The method to produce cheese chips according to the present invention allows obtaining healthy and tasty chips that are addressed to children, youth, and adults.

The object of the present invention has been explained in exemplary embodiments.

Example 1

The method to produce cheese chips consists in that the delivered cheese is weighted and recorded in the production report, and then cleaned and thoroughly rinsed with a water stream, and passed through a metal detector in order to eliminate possible impurities. The cheese is then cooled and frozen. Such prepared cheese is sliced into slices 7 mm thick, wherein while feeding the cheese to the slicer, the material is fed in a substantially uniform way in order to evenly load the slicing chamber. The cut slices are pre-dried at the temperature of 20 °C for 200 minutes to reach 10% humidity, after which they are cooled with air at the temperature of about 15°C, and the pre-dried cheese flakes are frozen to the temperature from minus 5 °C in a cold air stream at the temperature from minus 20 °C. The cut cheese slices are then pre-frozen in a fluidize bed tunnel. The pre- freezing is carried out at the temperature of minus 80 °C for 25 minutes. The pre-frozen cheese slices are mixed with a paprika topping in the amount of 30% by product weight that contains dried paprika and paprika flavour in the amount of 50%, pepper extract in the amount of 25%, and ground oregano in the amount of 25%. The spiced and pre-frozen slices in the amount of 3 kg are raised by rapid water evaporation resulting in the occurrence of characteristic smaller and larger air pockets increasing the volume of the product. The raising is carried out in a microwave and vacuum drier for 10 mins at the pressure of 25 hPa and the supplied microwave power of 24 kW, after which the slices are finally dried at the temperature of 65 °C for 1 hour to the humidity level of 7% producing the crunchiness effect. After the final drying, the slices are screened on a sieve screen with square mesh of 15 mm. The accepted fraction is bagged into aluminium Triplex 60x40 bags of 2 kg. Such prepared bags are labelled and packed in cartons of 3 pieces each. The finished product is stored in the storehouse on a pallet with 24 stacked cartons protected with stretch foil. Cheese chips are characterised in that their density is 0,188 g/cm 3 , their porosity measured by analyzing the displacement of sea sand is 74,3%, their crunchiness is 9,5 of microcracks in the process of destroying chip cheese as determined by penetrometer testing.

After that the slices are finally dried at the temperature of 40 °C for 4 hours to the humidity level of 4% producing the crunchiness effect, and the finally dried flakes are screened on a sieve screen with square mesh of 10 mm, and bagged. The flavour of the individual flakes is different, which is connected with the amount of topping deposited on the flakes during mixing. Cheese chips are characterised in that their density is 0,392 g/cm 3 , their porosity measured by analyzing the displacement of sea sand is 53,8%, their crunchiness is 8,5 of microcracks in the process of destroying chip cheese as determined by penetrometer testing.

Cheese slices are transported to the freeze tunnel and frozen to the temperature minus 5 °C by cold air stream at the temperature of minus 70 °C for 15 minutes. Then, the cheese slices in the amount of 8 kg are raised by rapid water evaporation resulting in the occurrence of characteristic smaller and larger air pockets increasing the volume of the product.

Example 8

Method to produce cheese chips that runs as in Example 7, except that the cheese is sliced into slices 1 mm thick and checked on an optical detector for foreign bodies. Cheese slices are transported to the freeze tunnel and frozen to the temperature of minus 15 °C by cold air stream at the temperature of minus 120 °C for 10 minutes.

Cheese chips are characterised with high crispness and crunchiness, resulting from the fact that the tissue of dried cheese slices is raised by means of air pockets by rapid volume water evaporation, increasing the volume of the product whose surface is covered with smaller and/or larger crispy air pockets. Such texture makes the cheese chips light and delicate, with crispness comparable with that of potato, carrot, beetroot, tomato, and topinambour chips. The percentage selection of components and additives in the embodiments is only an attempt at showing the possibilities offered by the application of cheese to produce cheese chips that can be made without salt as well as with hot and sweet flavours, and solely due to the known flavour preferences of the customers only typical product flavours have been presented. Cheese chips are characterised in that their density is 0,453 g/cm 3 , their porosity measured by analyzing the displacement of sea sand is 44, 1%, their crunchiness is 6 of microcracks in the process of destroying chip cheese as determined by penetrometer testing. The greater the amount of local cracks, which stimulates the process of biting the sample, the longer it takes to pick up noise events generate a better impression of crispness.

Example 9

Cheese chips were prepared according to the method disclosed in patent application No. PL396326 and according to Example 1. Cheese chips were characterised by higher density at level 0,726 g/cm 3 , lower porosity al level 9,09% and worse crunchiness where microcracks in the process of destroying chip cheese as determined by penetrometer testing were at the level 1,5.
