Description:
DESCRIPTION

Industrial food product with high water activity and filler and free of

preservative, coloring agent and emulsifier

Technical Field

The invention relates to a filled-laminar industrial food product with prolonged shelf life with the content, technology, packing, storage and distribution conditions used, and the production method of said food product.

The invention particularly relates to an industrial food product, and production method thereof, wherein packing technique comprising preservative gasses is employed, comprising the process of milk-based aerated sugary filling agent with low fat content, high water activity and free of preservative, coloring agent and emulsifier; production of bakery products; and combination of said bakery product with the filler agent.

Prior Art

In the prior art, food product produced such as pancake, crepe, and waffle can only be prepared as fresh and the filler varieties added within and/or on the same are added by the consumer prior to consumption. Said products cannot be supplied to the consumer as the end product and in an industrial fashion but as semi-products and they should be consumed in a very short time.

Another disadvantage of the products of the prior art is the use of preservative agents in the products containing high water activity fillers for the sake of prolonged shelf life. These preservative agents used, however, fails to provide adequate shelf life. Due to limited shelf life, the fillers used are restricted with products such as marmalade and jam with high sugar and low water activity. It is not possible to supply the consumers with fillers particularly with high milk content, low fat and free , of preservative and emulsifier with available methods and reasonable shelf lives. Another disadvantage, on the other hand, is the short storage period of the products containing milk. Therefore, the shelf life of the milk-based products is extended by addition of various preservatives and additives. The preservation period of the traditional homemade sugary desserts containing milk is also short even under refrigerator conditions.

When said milk-based products are used in conjunction with the bakery products for purposes such as filling and coating, microbial and chemical degradations occur within short time due to high water activity and moisture content. This fact poses a risk for human health and introduces products with deteriorated organoleptic properties.

One of the patents encountered on this subject matter during the studies conducted in the literature is the patent application no. US201 1280997 (A1 ) entitled 'Refrigerator-stable pancake & waffle batter in pressurized can'. Said application is a semi-product which contains flour, sugar, egg and water; can be stored in refrigerator; and put on the market in a pressurized can. A disadvantage of said invention is the necessity of applying cooking process by the consumer during consumption as it is a semi-product.

Another patent encountered is the patent application no. US5384139 (A). Said application is a semi-product containing cereal flour, egg, sugar, milk, and flavoring product. Said semi-product is packed in two separate phases as powder and liquid for the sake of improving shelf life.

In conclusion, a development in the relevant technical field concerning convenience food product such as pancake, crepe, and waffle with low fat content, high water activity, and free of preservative, coloring agent, emulsifier is necessitated due to aforementioned disadvantages and due to inadequacy of the existing solutions in this subject matter. Brief Description of the Invention

The present invention is an industrial food product with high water activity and filler, and free of preservative, coloring agent and emulsifier; which meets aforementioned requirements, eliminates all disadvantages and brings some additional advantages.

The primary object of the invention is to provide an industrial food product with high water activity (> 0.80), low fat content (max: 10%), filler and free of preservative, coloring agent and emulsifier and minimum 2 months shelf life at +4 to +10°C. An object of the invention is to have airing capability despite lower fat content compared to the products of the prior art. The product has lower fat content compared to the products of similar type (cake, waffle etc.). The fillers of the products having fillers of similar characteristics contain high rates of agents such as saturated fat (margarine etc.), emulsifier, and gelatin which can aerate. In order to aerate the filler of the invention, a multi-passage unit which is be used as crystallizer, homogenizer, and aerator is used. Air particles are linked into the matrices of the inputs used in the filler by means of the technology used.

A similar object of the invention is that the product contains water and fat but is free of emulsifier.

Another object of the invention is that the product is capable of aerating and preserving its stability (without any phase segregation and without losing air retention characteristics thereof) during the shelf life.

Another object of the invention is that the product is packed using packing materials inflated using oxygen and resilient and completely preservative gasses with low moisture permeability. Another object of the invention is to perform agitation-condensation-pasteurization- homogenization processes concomitantly using a multifunctional unit, and reducing the microbial load level down to zero. Moreover, concomitant execution of the processes in this unit not only reduces the byproduct conveying losses, but also prevents deterioration of the structure of the byproduct during pumping and transferring and reduces the energy costs.

Another object of the invention is to ensure that the temperature setting- crystallization- aeration-homogenization processes can be performed consecutively with a multi-passage secondary unit and at desired order, and to ensure that the absorption properties, stability of the filler and capability of retaining the air particles within the matrix structure remains stable during the shelf life. Another object of the invention is to reduce the fat globules contained in the colloidal structure obtained with aeration process to Nano size that cannot combine. By virtue of the surface increase due to such reduction, that is to say Nano size, re- coalescence due to variations in the environmental conditions is prevented, thus improving the product stability.

In order to fulfill the aforementioned objects, the invention is a production method for an industrial convenience food product with high water activity and filler, and free of preservative, coloring agent and emulsifier, comprising the process steps of;

a) preparation and cooking of the bakery products,

b) in order to prepare the filler,

-obtaining byproduct by executing agitation-condensation- pasteurization-homogenization processes within a single unit,

-reducing the temperature of the by-product and fixing the same at a certain range (50-55 °C),

-processing the by-product with fixed temperature in individual passages (K1 ,K2,K3,K4), and cooling the same down to a temperature (down to +8°C) far below the freezing point (15 °C) without allowing crystallization (constant agitation), and execution of crystallization- aeration processes by retaining air particles within the viscous matrix structure formed by minimizing the temperature variation at this temperature,

c) combining the cooked bakery product with the filler, and

d) packing with packages filled with preservative gases. Figures to Facilitate Comprehension of the Invention

In this detailed description, industrial food product with filler of the invention and its preferred embodiments are explained only for better understanding of the subject without any limiting effects.

The invention comprises an industrial food product with high water activity (> 0.80), low fat content (max: 10%), and filler, and free of preservative, coloring agent and emulsifier, and having minimum 2 months shelf life at +4 to +10°C. Said food product comprises bakery products (1 ) such as pancake and crepe containing filler (2). The food product of the invention is packed using flexible packing materials with low oxygen and moisture permeability. The packages are completely deflated and then filled with preservative gas mixtures (Nitrogen, C0 2 , similar gasses and mixtures), thus ensuring that the food product is not affected by the physical impacts until the package is open by means of the pressure which the gas mixture exerts in the package (inflated package).

In general, the production method for the food product of the invention comprises the process steps of;

-preparation of the filler (2),

-preparation and cooking of the dough layer (1 ) forming the bakery product, -combination of cooked bakery product (1 ) with the filler (2),

-packing of obtained food product.

Preparation of the filler (2)

In the prior art, the main ingredients that enable aeration of the filler products during the process are highly saturated fats or fats in solid form. The filler (2) of the invention, on the other hand, has desired aeration capability despite its lower fat content. The products currently available contain minimum 15% fat. The filler (2) of the invention contains lower fat (max: 10%) compared to available fillers with low density. What is meant with the aeration capability is to be able to reduce the density down to 0.2 gr/cm 3 levels by employing this method. Although the filler contains water and fat, no emulsifier is used. It has aeration capability and maintains its stability (without any phase segregation, without losing air retention characteristics thereof) during the shelf life. Said filler (2) can be converted into products and semi products (spreadable, depositable, and injectable) with long shelf life processable with high stability in broad viscosity (20.000-75.000 cp), density (0.20-1.2 gr/cm 3 ) and temperature (9-80°C) ranges.

Hereunder, the raw materials forming the filler (2) and the usable % by weight for these raw materials are provided in tabular form.

Table 1 : Content rates of the filler (2)

Said filler (2) (with low fat content, high water activity, high milk content (min 10%), free of preservative and emulsifier) is prepared using multifunctional and multi- passage equipment that enables execution of numerous process steps concurrently, consecutively and at desired order. Said equipment comprises;

-a multifunctional unit (HPK) which enables execution of agitation- condensation-pasteurization-homogenization processes concurrently and reduces microbial load level down to zero;

- a secondary multi-passage unit (K1 ,K2,K3,K4) which maintains the absorption property and stability of the filler (2) during the shelf life, and enables execution of the temperature setting-crystallization- aeration-homogenization processes consecutively and at desired order; and

-an interim process tank (T1 ) which sets the temperature of the filler (2) mixture between said two units.

There is no technology available in the prior art that is multi-staged, multi-functional, and capable of making input addition with special flow rate-controlled dosing systems before each stage. Figure 2 illustrates the schematic view of the equipment used for the production of filler (2).

• Agitation-Condensation-Pasteurization-Homoqenization Process

During preparation of the filler (2), the preliminary processes are performed within the multifunctional unit. The multifunctional unit is a combined unit that enables execution of agitation-condensation-pasteurization-homogenization processes within the same equipment. Use of multifunctional unit reduces byproduct conveying losses. It further eliminates the risks of contamination from pumps and installation elements and change of product characteristics. During any stage of the processes, controlled feed of the substances that do not dissolve within each other under normal conditions is made possible, thus products, where stable mixtures cannot be achieved under normal conditions, can be mixed. Further use of chemicals is not required in order to form said stable mixtures. Moreover, capability to execute 3 processes (condensation-pasteurization-homogenization) within the same unit at the same time reduces the energy costs required for the production process. Use of combined unit precludes secondary processing of the mixture formed by the existing inputs unnecessarily due to some inputs incorporated in intermediate passages. This, in turn, ensures that the nutritional value of the final product sustains minimum damage, that the product is stable and combination of inputs which do not mix easily.

The fluid raw materials (water, glucose, glycerin) forming the filler (2) are added into the multifunctional unit and agitated at 30°C until achieving a homogenous distribution. Then, the powdered raw materials (milk powder, starch, salt, vanillin) forming the filler are added by keeping the temperature constant and effectively dissolved within fluid raw materials through high speed (1000-3000 d/d) agitation without pellet formation. Then, thickener (Sodium alginate) and fat (Coconut-palm mixture) are added. Then, the mixture is agitated with the agitator (high shear mixing) at high speed (1000-3000 d/d) in order to enable the raw materials in the mixture to form a homogenous matrix. The mixture homogenized through high speed agitation is then transformed into the byproduct through condensation and pasteurization at low temperature (60-80°C) under vacuum (-0.8 bar) until desired dry matter value (Brix: 65-75%) is achieved. Viscosity of the obtained byproduct varies in the range of 20.000-28.000 cp while its density varies in the range of 1 -1 .2 gr/cm 3 . Achieving desired viscosity and density properties, the filler (2) is then fed to the cooling interim tank (T1 ) through closed circuit pumps and piping.

By virtue of the multifunctional process unit, the mixture is processed under same medium without relocation. In this manner, fillers (2) with desired properties can be produced through processes (agitation, condensation, pasteurization, and homogenization) applicable in desired order with minimum process steps without any risk of microbial contamination.

• Interim Process Tank

The interim process tank (T1 ) comprises a tank with heating-cooling jacket, automatic temperature control, variable-speed agitator, and pump for transfer to the next operation, and level control.

In the interim process tank (T1 ), the temperature of the byproduct obtained through preliminary processes in the multifunctional unit (HPK) is automatically set to the next process temperature (50-55°C). Therefore, the viscosity of the byproduct achieves a value in the range of 25.000-35.000 cp. Moreover, it is also possible to store the byproduct in the interim process tank. In this tank, automatic agitation process is performed until the temperature of the byproduct mixture is reduced down to the temperature required for next operation. When desired temperature is reached, the byproduct mixture is forwarded to the feed tank (T2) of the next process. This tank has desired temperature and enables in time maintaining the temperature variations at a range not exceeding ±3 °C. Moreover, it ensures constant feed to the multi- passage crystallization-homogenization-aeration unit, thus ensuring quality sustainability of the final byproduct. The pump feeding the byproduct from the tank (T2) to the crystallization-homogenization-aeration unit is designed with precision flow rate adjustment and automatic control. · Crystallization- Aeration-Homogenization Process

The byproduct leaving the interim process tank (T1 ) is then received by the feed tank (T2) that feeds product to the next operation at desired flow rate and temperature. From the feed tank, the byproduct is transferred to the crystallization-aeration process unit wherein processes such as temperature fixation, crystallization, density adjustment, and obtaining processable conditions can be executed at a single unit. Crystallization-aeration process unit is a multi-passage (K1 ,K2,K3,K4) unit wherein critical parameters such as temperature and pressure can be adjustable in a broad range. At crystallization and density adjustment stages of this unit, the gasses (N 2 , C0 2 ), aromas and other pumpable inputs are added to the mixture. Examples for such inputs include aromas, natural coloring agents, gelling agents, food particles pumpable in liquid, some special food fats, water, etc.

Use of crystallization-aeration process unit enables addition of different inputs (aromas, natural coloring agents, gelling agents, food particles pumpable in liquid, some special food fats) between or at the end of each passage and providing different properties (low density, high stability, broad viscosity range, distinct tastes, distinct absorption properties etc.) to the product.

The ability of adding pumpable ingredients not intended to be subjected to heat treatment to the passages with different temperature between each passage and thus adjusting the temperature, agitator speed, inner pressure parameters of each passage for the ingredients sensitive to the temperature (aromas, natural coloring agents, gelling agents, food particles pumpable in liquid, some special food fats) enables transfer of the same to the mixture without any damages.

The temperature of the emulsion entering the system is fixed at the first passage (K1 ) and thus variations that might affect the stability of the end product can be prevented by virtue of the thermal variation property of the multi-passage system. Prior to final passage (K4), in the second and third passages (K2,K3), critical parameters that are not possible to be furnished at other single passage prior art technologies can be regulated (temperature, pressure, circulation). In this manner, aeration of the emulsion and regulating the fat content in the emulsion to desired crystal structure are ensured. Thus, it is possible for the product to achieve desired colloidal structure. The agitator characteristics of the multi-passage unit at its inner design and control of the parameters such as agitator speed, inner pressure that can be set individually and inner temperature enable reduction of the product temperature to very low values (down to +9°C) without solidification and the desired structure can be achieved by utilizing the rheological properties of the product at this temperature. Currently, there is no embodiment which is multi-passaged and where the parameters of each passage can be adjusted independently of each other or such embodiments are not used for this purpose. By means of the characteristics of the multi-passage unit, homogenous distribution of the air cells at small diameters and between fat globules can be achieved by aerating the obtained emulsion, thus obtaining a matrix structure with broad surface area. Homogenous distribution is ensured by utilizing temperature, pressure, agitator speed, agitator type etc. features of the multi-passage unit.

The fat globules contained in the obtained colloidal structure are reduced down to a size (Nano) that doesn't enable them to merge. In this manner, the quantity and surface area of the fat globules at the same unit area increase logarithmically. The surface of the fat globules subjected to the temperature applied to the same unit area becomes resistant to heat more than any surface obtained with known technologies and methods. As the surface area of the fusible inputs reduced to Nano size increases, when same amount of heat is applied, the heat per unit area is reduced compared to the available products (Total heat/ surface relation). This, in turn, ensures that the product is more resistant to heat variations compared to other products and renders the product more stable.

Re-coalescence arising from variations at the environmental conditions is precluded as the ingredients in the filler are reduced to colloidal size (1 nm-1 \im), thus improving the product stability. In the final passage (K4), on the other hand, the temperature of the filler (2) is adjusted without deteriorating the structure of the crystals contained in the colloidal structure obtained in the previous third passage (K3). In this manner, the filler (2), the structure of which is modified up to a non-processable extent in the previous passages, is again rendered processable.

First of all, the temperature (15°C - 30°C) of the byproduct entering the multi-passage unit is fixed in the first passage (K1). In this manner, variations that might affect stability at the properties of the final product are precluded.

The density of the byproduct is reduced (reduction down to 0.2 gr/cm 3 ) by aerating the byproduct in the third passage (K3) prior to the final passage (K4).

Aerated and crystallized byproduct obtained is taken to the final passage (K4) and its temperature is set to 9±1 °C in such manner to experience no variation at its structure, thus, is rendered processable.

The byproduct with insufficient crystallization-aeration processes in the multi-passage unit is returned to the De-crystallizer- De-aerator tank (DT) for further processing.

Preparation and cooking of the dough layer (1 ) forming the bakery product

The dough layer (1 ) forming the bakery product is prepared and cooked in an environment that is completely closed to external environment for zeroing microbial risk, where the temperature is maintained under control (12-15°C), the ambient air is cleaned using special filters, having positive pressure, special hygiene barriers and sanitation conditions (air shower, UV, special lighting, floor coating materials, dyes, special equipment etc.).

Hereunder, the raw materials forming the bakery product (1) and the usable % by weight for these raw materials are provided in tabular form.

At a certain stage of cooking, the dough layer (1 ) should be inversed in order to achieve homogenous color on both surfaces. It is possible to shape the dough layer (1 ) smoothly without using template. Moreover, rapid cooking enables high moisture content for the dough layer (1 ).

Dough layers (1 ) can be prepared with any desired geometric (square, round etc.) shape. • Pre-Cooling

Cooked bakery products (1) are cooled down to a suitable temperature (28-30°C) before addition of filler (2) thereon or therein. Depositing, Sandwiching and Seasoning Process Steps

- Cooked bakery product (1 ) is cooled and sorted in order to make it suitable for depositing filler (2).

- Special filler depositor (a depositor at very narrow grammage tolerances (±1 %), and broad viscosity range (4.000-80.000 cp) and that doesn't exert pressure-temperature to the product) enables coalescence of fillers (2) with a broad range of physical properties with the dough layer.

- Food product of the invention can be prepared in the form of a single layer (1 ) with filler (2), two or more layers (1 ) with filler (2) therebetween, and layers (1 ) containing multiple fillers (2) (mingled, abreast, superposed etc.).

- Patterns can be printed on the bakery products (1 ) combined with the filler (2) through heat treatment or food dyes.

Packaging process steps

- Thermoform packaging equipment (form, fill, seal) is used for packing the food product of the invention.

- The package geometry can be designed specifically for the product. The package can also be designed in a different manner if and when desired. By means of this technology, resilient lower and upper packing materials (6,7) can be shaped in desired geometry and at the time of introducing the product to the package, the air between upper and lower material is completely vacuumed out and replaced with pressurized preservative gas mixtures and sealed. - The oxygen in the package medium is reduced down to zero by using packing materials with low moisture and gas permeability. In this manner, it is possible to sterilize the product in the package from microbial risks during the shelf life.
