Description
Method for preserving food products, in particular vegetable and soft fruit pieces
[001] The invention relates to a method of preserving food products, in particular vegetable and soft fruit pieces, exposed to the risk of bacterial growth and rapid putrefaction processes, for storage in the frozen state.
[002] There is known from the Russian patent specification RU-2185080 a method of jet freezing of semi-products comprising initial cooling of the semi-products in a jet of cool air, rapid freezing and glazing, the temperature and moisture content at the initial cooling are moreover much higher than at the rapid freezing step. The air from the rapid freezing chamber is passed to the initial cooling chamber, next to the glazing chamber, and from there again to the rapid freezing chamber. The moisture for glazing is obtained from the moist air by desublimation at atmospheric pressure.
[003] Furthermore, there is known from the American patent specification US-2861889 a method for preparation of candied glaze on frozen food by using dry boiled food starch and dry sugar in the ratio 1 to 10 parts of boiled starch for each 150 parts of sugar and freezing the food when the starch can still absorb water during the freezing process and forms a gel that sticks to the surface of the foodstuff and binds sugar in the form of candied glaze. Moreover, colouring and flavouring agents are added to the dry sweetening mix.
[004] Moreover, there is known from the American patent specification US-6143343 a method of improving taste and reducing bacterial contamination of seafood, in particular oysters, by ice glazing.
[005] The object of the present invention is to develop a method for preserving food products that would make the storage period longer along with tolerating temporary freezing temperature fluctuations during storage and at the same time improving their taste value and appearance.
[006] The essence of the freezing and glazing method with the use of an aqueous solution mist according to the present invention is that immediately before, during and/or after the initial freezing stage, the food product is UV-irradiated, preferably irradiated with UV-C light, and/or the moisture content of the air used for glazing is increased by a mist of an aqueous solution containing from 0.01 to 80% of flavouring agents and/or taste enhancing agents and/or 0.5 - 5 percent glycerine. The aqueous solution deposited in the form of glaze contains
with respect to the food product weight from 0.01 to 1 percent of taste enhancing agents from the group of inosates and/or guanylates, preferably as sodium, calcium or potassium salts, and/or up to 20% of natural flavourings which differ in taste from the frozen food product.
[007] An advantage of the method according to the present invention is that the bacterial DNA structure is destroyed by UV-irradiation and thereby the initial level of rotting processes is lowered in cases of temporary temperature excursions to temperatures higher than recommended in continuous storage of frozen food, for instance, in the case of a failure of the network supplying power to refrigerating units. In the glazing process, taste value of the food product is improved by also using in the aqueous solution applied for glazing a taste enhancing agent or a mixture of such agents along with other foodstuffs like natural juice or an extract of preserved foodstuff.
[008] The method consists in initial surface freezing using blast freezing (IQF) in a fluidisation-belt tunnel in the temperature range obtained by expanding liquid nitrogen, - 195°C, to the temperature of -15°C, and subsequent deep freezing and glazing by using a mist of an aqueous solution of foodstuffs. Immediately before, during and/or after the initial freezing step, the food product is UV-irradiated, preferably by UV-C light. At the glazing stage, the moisture content of the air used for glazing is increased with the use of a mist of an aqueous solution containing 0.01 to 80% of flavouring agents and/or taste enhancing agents, and/or 0.5-5 percent glycerine. The aqueous solution deposited in the form of glaze contains with respect to the food product weight from 0.01 to 1 percent of taste enhancing agents from the group of inosates and/or guanylates, preferably as sodium, calcium or potassium salts, and/or up to 20% of natural flavourings which differ in taste from the frozen food product.
The invention is elucidated below in implementation examples.
[009] Example I. A food product in the form of potato chips undergoes a process of blast freezing (IQF) in a fluidisation-belt tunnel with simultaneous UV-C irradiation. A stream of cold air is directed vertically up through the belt and a layer of products. Continuous separation and fluidisation of the product occurs and rapid freezing of its surface. At the same time, due to UV-C radiation, DNA structures of the bacteria which could have contaminated the potatoes are destroyed. The time of the surface freezing of the product depends on the device design, the product and the applied temperature in the range from the temperature achieved by expanding liquid nitrogen to -15°. By expanding the liquid nitrogen, the temperature can be lowered to -195°C. After initial hardening of the frozen product surface, in the freezing chamber with an air stream flowing from the bottom and churning up the product
layer, for a time longer than the initial freezing, the process of complete freezing of potato chips is conducted, at the same time the moisture content of the air used for glazing is increased with a mist of an aqueous solution containing 5 percent of vegetable flavourings extract, 0.5 percent glycerine, 1 percent of taste enhancing agents in the form of disodium inosate (E631) and potassium guanylate (E628) and 10 percent sodium glutamate. The glazing process is conducted in a separated terminal part of the freezing tunnel. The film formed on the product surface makes a kind of very tight, closely sticking packaging that protects the plant tissue from air access and prevents tissue water loss and further adverse changes in the product quality. The vegetable flavouring extract improves the taste value of potato chips and the addition of taste enhancing agents in the form of disodium inosate (E631) and dipotassium guanylate (E628) and 10 percent sodium glutamate (E621) affects umami.
[010] Example II. Soft fruits like raspberries undergo irradiation with UV-C lamps placed in the fruit layer directly before the blast freezing in the fluidisation-belt tunnel. Due to UV-C radiation, DNA structure of bacteria that grew in the juice and on the surface of raspberries is destroyed. In the tunnel, by expanding liquid nitrogen, a temperature decreased to -195°C is achieved, at the same time continuous separation and fluidisation of raspberry fruits occurs and rapid freezing of their surface. After initial hardening of the frozen product surface, in the freezing chamber with an air stream flowing from the bottom and churning up the product layer, for a longer time and at higher temperature, the process of complete freezing of raspberries is conducted, at the same time the moisture content of the air used for glazing is increased with a mist of an aqueous solution containing 70 percent of raspberry juice, 5 percent glycerine, 0.8 percent of taste enhancing agents in the form of calcium inosate (E633) and guanylic acid (E626). The glazing process is conducted in a separated terminal part of the freezing tunnel. The film being formed on the product surface makes a kind of very tight, closely sticking covering that protects the plant tissue from crushing and air access. The addition of taste enhancing agents affects umami when consuming the raspberry fruits covered with a raspberry juice film, and the addition of glycerine improves the appearance of raspberries after thawing, because water vapour contained in the air does not form frost on the surface of the fruit. The product is generally stored at a temperature lower than the glazing temperature.
