Method for the production of dried supplies from vegetable raw materials

 

(57) Abstract:

The invention relates to the technology of production of dried supplies from vegetable raw materials. Raw materials in the preparation process before the drying process a drug derived from biomass micromycete Mortierella exigua for a given technology, and maintain. The invention improves the quality of supplies.

The invention relates to the technology of production of dried supplies from vegetable raw materials intended for use in whole or slices in the composition of sterilized canned food.

A method of producing supplies of plant materials, including preparation, in which raw materials are treated with a mixture of chitosan and arachidonic acid and incubated for 2-5 hours, and the removal of moisture (RU # 2167531 C2, 27.05.2001).

The disadvantage of this method is to obtain supplies, prone to cooking during further processing into sterilized canning.

The technical result of the invention is to improve the quality of supply, in particular improved resistance form for subsequent recovery, including when heated to a temperature sterilization of canned food.

This is the preparation, in the process where raw materials are treated immune stimulator and incubated for 2-5 hours, and the removal of moisture, according to the invention as immunostimulant drug use, obtained by sequential extraction of biomass micromycete Mortierella exigua nonpolar solvent in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue, in amounts of about 0.01% by weight.

The method is implemented as follows.

Dry biomass micromycete Mortierella exigua extracted with a nonpolar solvent, for example carbon dioxide or hexane, supercritical condition. At this stage, separating the first extract used in the future when receiving the drug. Further biomass sequentially extracted with water, alkali, water, acid, water, alkali and water. Obtained after completing all these stages of extraction of the solid residue combined with the first extract. Thus obtained product contains mainly chitosan and higher polyunsaturated fatty acids. As part of related substances no toxic, carcinogenic, mutagenic and anti-nutritional, vases imennyh fatty acids are present in significant amounts of arachidonic and eicosapentaenoic acids, which in combination with chitosan have a high immunostimulatory activity compared to higher plants. At the same time, as part of the preparation there are no substances that can inhibit this activity. This allows you to use the drug as a coil resistance of dried vegetable supplies to the mould during storage.

Plant material is subjected to the preparation, the composition of which is determined by the kind of raw material. In the preparation of the raw material is treated with a drug derived from biomass micromycete Mortierella exigua on the above-described technology, in the amount of about 0.01% by weight. It is most expedient to carry out the processing after washing raw material and drying the surface and definitely before any operation machining type cleaning, cutting, branch crests, knock out the bones, etc., In this case, for 2 to 5 hours depending on the type and size of the fruit being processed substrate is assimilation part of immunostimulatory substances, which do not exceed 0.1 by weight of the preparation, and induction of resistance to the development of microflora. As noted above, the preparation of the biomass micromycete Mortierella exigua in considerably the effective pectic substances of vegetable raw materials, mainly in the surface layer, because the mentioned time high-molecular compounds do not have time to diffuse to a considerable depth. This leads to the conversion of a portion soluble pectic substances of vegetable raw materials in > protopectin and strengthening of the structure of the outer layers of plant materials. Further, after soaking remove moisture allows to fix the past in raw materials chemical and structural changes.

Thus obtained supplies in storage are resistant to the development of mold as well as the closest analogue, but due to increased introduction of higher fatty acids with antioxidant properties, is somewhat better retain color. At the same time when the recovery and use of supplies in the composition of sterilized canned their flash is greatly reduced.

Example 1.

Pear varieties Priest washed, treated with a mixture of arachidonic acid and chitosan in an amount of 10 g/t in the closest analogue or drug derived from biomass micromycete Mortierella exigua on the above described technology as a non-polar extractant carbon dioxide, as alkali - is Yaya seed chamber and the stem, and dried. After 1 month of storage samples supplies reference and experienced parties inoculant mold spores of the fungus Aspergillus niger in number 21012spores/g and incubated at 36C for 10 days. The development of mold in both cases is not observed. After 2 months of storage of supplies used for the production of juice. The number of cracked slices in the reference compote is 8%, in the experimental compote 2%.

Example 2.

Apricots varieties Anniversary Navoi wash, separate the stem, is treated as in example 1, but using a drug derived from biomass micromycete Mortierella exigua using as a nonpolar solvent hexane, as alkali - hydroxide ammonium and propionic acid. After soaking for 5 hours apricots cut in half, removing the seeds, and dried. Tests funginertness carried out as in example 1, but using spores mold fungus Penicillium funiculosum. The result is the same as example 1. After 2 months of storage of supplies used for the production of juice, the Amount of boiled halves in the standard was 98%, in the experience of 7%.

Example 3.

The seed vegetable pea varieties Sunrise canning maturity stage process of example 1, but the popular extractant nitrous oxide, as the alkali is sodium hydroxide and acetic acid. After processing, the peas stand for 3 hours and dried. Tests funginertness carried out as in example 1. The result is the same as example 1. After 6 months of storage supplies used for the production of canned Green peas”. The number of cracked grains, fields of grain and detached shells in the standard is 88%, in the experience of 3.5%.

Thus, the proposed method can improve the quality of supplies from vegetable raw materials.

Method for the production of dried supplies from vegetable raw materials, including preparation, during which the raw material is treated with immunostimulant and incubated for 2-5 hours, and removing moisture, characterized in that as immunostimulant drug use, obtained by sequential extraction of biomass micromycete Mortierella exigua nonpolar solvent in the supercritical state, water, alkali, water, acid, water, alkali and water followed by combining the first extract from the solid residue, in amounts of about 0.01% by weight.
