Abstract

FIELD: food processing industry, in particular production of foodstuff for infant nutrition.

SUBSTANCE: cereal is cooked in water with pectin additive in amount of 0.5-1.5 %, mixed with fruit-and-vegetable puree and preparation, obtained from biomass of Mortierella elongata micromycete according to claimed technology, homogenized and dried.

EFFECT: target product of improved quality.

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 of obtaining 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 by weight, and when mixing, an additional preparation is introduced, obtained by sequential extraction of the biomass of micromycete Mortierella elongate with a non-polar supercritical extractant, water, acid, water, alkali, water, acid and water, followed by union of the 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 the micromycete Mortierella elongata 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 sequentially 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 prescription amount of pectin is introduced into the prescription amount of water and maintained for swelling and dissolution of pectin to obtain a 0.5-1.5% solution. The resulting solution was 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 a preparation from biomass micromycete Mortierella elongata 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 powder 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 is crumpled upon storage in an unpressurized package after 1-2 days.

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