Description:
MARINADE

This invention relates to a fat composition, a marinade comprising the fat composition and a method for its production.

Shea oil (butter) is a fat obtained from the shea tree. The butter is sometimes fractionated to form a stearin fraction (shea stearin) and an olein fraction (shea olein). Shea products are used in cosmetics and in the food industry. Shea oil is relatively rich in stearic and oleic acids. A marinade is a mixture of ingredients, in which meat, fish, or other food is soaked before cooking in order to flavour and/or soften it. Typically, marinades comprise oil, wine, spices, vegetables or similar ingredients. Marinades are usually applied to refrigerated food and the marinating process usually takes place at refrigerator temperatures of about 5 °C for a period of several hours.

Marinades are described in, for example, US 2016/302460.

Fats and oils are important components of food products and can be responsible for texture, mouthfeel and flavor attributes. For instance, the solid fat profile can affect properties such as flavor release and structure.

Fats and oils contain glycerides. Glycerides may be in the form of mono-, di- or tri- glycerides having one, two or three fatt acid acyl groups, respectively, bonded to a glycerol backbone. Triglycerides are the predominant type of glycehde in edible fats and oils.

Fats and oils are sometimes subjected to an interesterifi cation process which randomises the fatty acid acyl residues amongst the glycehde molecules. This can alter the physical properties of the fat or oil. Usually, interesterifi cation is carried out in order to effect complete randomisation of the fatty acid acyl groups.

US 4482576 describes the directed interesterification of an edible oil. The process is carried out under low temperature conditions such that some of the oil is in the solid phase. This results in a product that does not have complete randomization of the fatty acid residues but has a partially randomised distribution of the fatty acids depending on the composition of the liquid and solid oil phases at the time of randomization. There remains a need for improved marinades, in particular having good consistency and/or viscosity both at refrigeration temperatures and at room temperature, so that the marinade has sufficient flowability to be applied to food when taken out of a refrigerator, and to be reapplied at refrigerator temperatures, and yet which does not run off the food at higher room temperatures.

According to the present invention, there is provided a fat composition comprising:

greater than 45% by weight oleic acid;

from 10% to 35% by weight stearic acid; and

from 1% to 10% by weight palmitic acid;

said percentages of acids referring to acids bound as acyl groups in glycerides in the fat composition and being based on the total weight of C8 to C24 fatty acids; and

greater than 5% by weight of combined P2St, PSt? and StStSt triglycerides based on total triglycerides present in the composition, and a weight ratio of (StOSt+POSt):(StStSt+PStSt) triglycerides of less than 3, wherein P is palmitic acid, O is oleic acid and St is stearic acid.

The fat composition of the invention has been found to be particularly useful as a fat for a marinade. For example, the fat composition imparts good rheological properties to the marinade, generally in a blend with one or more liquid oils, allowing the marinade to be applied at refrigeration temperatures but to generally retain consistency at higher temperatures.

Also provided by the invention is a process for making the fat composition of the invention, which comprises chemically interesterifying a fat at a temperature of from 30 to 50 °C. Further provided by the invention is a marinade comprising the fat composition of the invention, preferably in an amount of from 1 % to 99% by weight, and optionally one or more ingredients selected from herbs, spices and vegetables.

In another aspect, the invention provides the use of the fat composition of the invention in a marinade.

In a further aspect, the invention provides a method of preparing a food product which comprises contacting the marinade of the invention with food for cooking, preferably with raw meat, and cooking the marinated food. The term "fat" refers to glyceride fats and oils containing fatty acid acyl groups and does not imply any particular melting point. The term "oil" is used synonymously with "fat". Fats predominantly comprise triglycerides. Amounts of triglycerides specified herein are percentages by weight based on total triglycerides present in the fat composition. The notation triglyceride XYZ denotes triglycerides having fatty acid acyl groups X, Y and Z at any of the 1 -, 2- and 3- positions of the glyceride. The notation A2B includes both AAB and ABA, and AB 2 includes both ABB and BAB. Triglyceride content may be determined for example by GC (ISO 23275).

The term "fatty acid", as used herein, refers to straight chain saturated or unsaturated (including mono- and poly- unsaturated) carboxylic acids having from 8 to 24 carbon atoms. A fatty acid having n carbon atoms and x double bonds may be denoted Cn:x. For example, palmitic acid may be denoted C16:0 and oleic acid may be denoted C18:1. Percentages of fatty acids in compositions referred to herein include acyl groups in tri-, di- and mono- glycerides present in the glycerides as is customary terminology in the art and are based on the total weight of C8 to C24 fatty acids. The fatty acid profile (i.e., composition) may be determined, for example, by fatty acid methyl ester analysis (FAME) using gas chromatography according to ISO 15304. The fat composition of the invention comprises greater than 45% by weight oleic acid based on the total weight of C8 to C24 fatty acids. Preferably, the fat composition comprises from 50% to 75% by weight oleic acid, such as from 50% to 70% by weight or from 51 to 60% by weight oleic acid.

The fat compositions of the invention may be made from naturally occurring or synthetic fats, fractions of naturally occurring or synthetic fats, or mixtures thereof, that satisfy the requirements for fatty acid and triglyceride composition defined herein. A preferred composition of the invention comprises, consists essentially of, or consists of an interesterified shea olein. Alternatively, the fat composition may comprise, consist essentially of, or consist of an interesterified stearin fraction of high stearic high oleic sunflower oil or an interesterified high stearic high oleic sunflower oil.

The fat composition of the invention is preferably made by a process which comprises chemically interesterifying a fat at a temperature of from 30 to 50 °C. Directed interesterification in this way results in a non-random distribution of fatty acids across the triglycerides. Preferably, the interesterification is carried out chemically, more preferably using sodium methoxide as catalyst. The interesterification is preferably carried out for at least 200 hours, such as from 200 to 400 hours. The fat that is interesterified in the process of the invention is preferably a shea olein or a stearin fraction of high stearic high oleic sunflower oil.

Preferably, the marinades are packaged, for example in a bottle or jar.

A method of preparing a food product comprises contacting the marinade of the invention with food for cooking, preferably with raw meat, and cooking the marinated food. Suitable foods for marinating with the marinade of the invention include, for example, chicken, turkey, duck, goose, beef, veal, pork, lamb, fish and bean curd. The listing or discussion of an apparently prior-published document in this specification should not necessarily be taken as an acknowledgement that the document is part of the state of the art or is common general knowledge.

Preferences and options for a given aspect, embodiment, feature or parameter of the invention should, unless the context indicates otherwise, be regarded as having been disclosed in combination with any and all preferences and options for all other aspects, embodiments, features and parameters of the invention.

The following non-limiting examples illustrate the invention and do not limit its scope in any way. In the examples and throughout this specification, all percentages, parts and ratios are by weight unless indicated otherwise. Examples

Example 1

5 kilogram shea olein was chemically interesterified by mixing with sodium methoxide at 90°C to 1 10°C, followed by reaction at 37°C to 44° C for at least 200 hours. The analytical results for the product are shown in Table 1.

Example 2 5 kilogram of a stearin fraction obtained from high stearic high oleic sunflower oil by dry fractionation was chemically interesterified by mixing with sodium methoxide at 90°C to 1 10°C, followed by reaction at 37°C to 44°C for at least 200 hours.

The consistency of the marinade oil blends stored at 4°C and 20°C was compared in duplicate using a Bostwick Consistometer. The results were reported as the distance travelled (cm) in 30 seconds. The difference between the scores at 4°C and 20°C was calculated and the results are given in the following Table.

The performance of marinade oil blends containing the fats of Example 1 and Example 2 (Marinade oil blends A and B) performed better compared to the fats made by standard interesterifi cation (Marinade oil blends C and D). Both marinade oil blend B and marinade oil blend A could be successfully used in oil-based marinades. Example 5

The evaluation was repeated twice and the average calculated. The difference between the scores at 4°C and 20°C was calculated. The performance of marinade oil blends containing the fats of Example 1 and Example 2 (Marinade oil blends A and B) performed better compared to the products made by standard interesterification (Marinade oil blends C and D). Example 6

Two different marinades were prepared using the marinade oil blends. The formulations are shown in the table below.
