Abstract

FIELD: food industry.

SUBSTANCE: one should sieve the groats and pectin to be passed through magnetic catcher and washed. Dry Pythium ultimum micromycete biomass should be extracted with a nonpolar extracting agent, for example, carbon dioxide or hexane in supracritical state. The first extract should be separated against biomass, and the latter should be successively extracted with water, acid, water, alkali, water, acid and water. On finishing these operations one should combine solid residue with the first extract at obtaining the preparation. Formula pectin quantity should be introduced into formula water quantity to be kept for swelling and pectin dissolving at obtaining 0.5-1.5%-solution to be filtered. Pectin solution should be mixed with groats prepared at the ratio of 1:10. The groats should be cooked to a pulp up to the content of dry matters being about 11.5%, then fruit-vegetable puree should be introduced into the groats at the quantity ranged 30-50% and a preparation obtained out of the biomass at the quantity of 0.01-0.02% against the weight of the mixture under manufacturing. The mixture should be mixed, homogenized and dried up. At another method of drying, not a spraying one, dried mixture should be reduced up to a powder-like condition to be sieved. The innovation enables to increase the quality of the target product for it is very easily reduced with water up to homogeneous, puree-like consistence, forms no agglomerates and demonstrates no lumpiness when being stored in nonhermetic packaging for 1 wk at air moisture up to 76%. Moreover, the target product is of curative-prophylactic properties being characteristic for products at increased pectin content, of hypoallergenic action, in particular. The innovation, also, enables to decrease age qualification in applying the mixture and is recommended for nutrition in children since the age of 3.5 mo.

EFFECT: higher efficiency of manufacturing.

Description

The invention relates to a technology for the production of baby food.

A known method of obtaining a dry mixture for baby food, involving boiling cereals in water, mixing it with fruit and vegetable puree, homogenization and drying (RU 2013066 C1, 05/30/1994).

The disadvantage of this method is to obtain the target product, prone to clumping.

The technical result of the invention is to improve the quality of the target product.

This result is achieved by the fact that in the method for producing a dry mixture for baby food, comprising boiling cereals in water, mixing it with fruit and vegetable puree, homogenizing and drying, according to the invention, pectin in an amount of 0.5-1.5% is introduced into the water before boiling the mass, and when mixing, the preparation is additionally introduced, obtained by sequential extraction of the biomass of Pythium ultimum micromycete with a non-polar supercritical extractant, water, acid, water, alkali, water, acid and water, followed by combining neniem first extract with the solid residue in an amount of 0.01-0.02% by weight of the prepared mixture.

The method is implemented as follows.

Raw fruits and vegetables are prepared according to the traditional technology adopted for it and wiped with mashed potatoes. It is allowed to use mashed semi-finished product preserved by aseptic method. The groats are sieved, passed through a magnetic trap and washed. Pectin is sieved and passed through a magnetic trap. The dry biomass of Pythium ultimum micromycete is extracted with a non-polar extractant, for example carbon dioxide or hexane, in a supercritical state. At this stage, the first extract is separated, which is used later in the preparation. Next, the biomass is subsequently extracted with water, acid, water, alkali, water, acid and water. The solid residue obtained after completion of all the extraction steps listed above is combined with the first extract. The recipe amount of pectin is introduced into the recipe amount of water and kept for swelling and dissolution of pectin to obtain a 0.5-1.5% solution. The resulting solution is filtered.

The prepared cereal is mixed with a pectin solution in a ratio of 1:10, which is traditionally used for cooking cereals in the production of baby food, and is boiled to a solids content of about 11.5% in cereal, as in traditional technologies for the production of baby food. Into boiled cereal, fruit and vegetable puree is introduced in an amount from 30 to 50%, recommended for the corresponding type of puree used in similar mixtures for baby food, and Pythium ultimum micromycete biomass preparation in an amount of 0.01-0.02% of the mass of the prepared mixture, mix, homogenize and dry. In the drying method other than spray, the dried mixture is crushed to a powdery state and then sieved. The residual moisture in the target product should not exceed 5%.

Due to the increased pectin content in the target product by about 2 times compared with the closest analogue, the target product obtained by the proposed method has therapeutic and prophylactic properties characteristic of products with a high pectin content, of which a hypoallergenic effect is especially important for baby food products. This, combined with the content in the target product of arachidonic acid, which is absent in the product obtained by the closest analogue, allows reducing the age limit and recommending the product obtained by the proposed method for feeding children from 3.5 months of age.

It has been experimentally established that the target product obtained by the proposed method is easily restored by water to a uniform puree consistency, does not form agglomerates and does not crumple when stored in an unpressurized packaging for a week at an air humidity of up to 78%. The product obtained by the closest analogue crumbles upon storage in an unpressurized package after 1-2 days.

Thus, the proposed method improves the quality of the target product.
