Description

The technical solution relates to the food industry, namely to methods of producing a product from sea grasses of the ZOSTERACEAE family and can be used to obtain a biologically active product with therapeutic and prophylactic properties.

Known methods of processing sea grass of the Zosteraceae family to obtain a pectin-containing product (and.with. RU No. 921500, item RU No. 2000064). The methods include grinding raw materials, hydrolysis of raw materials with a solution of hydrochloric acid and extracting pectin with ammonium oxalate of 1.0% concentration at a temperature of 50 to 85 ° C.

The disadvantages of the known methods are to obtain a processed product with only one useful property: the resulting product according to a.c. RU, No. 921500 has only the properties of a sorbent, and according to item RU, No. 2000064, the product contains a complex of substances with P-vitamin activity, while other useful components of sea grass are not used. In addition, the disadvantages of the known method are the use of chemical reagents and auxiliary substances, including a non-food extractor (ammonium oxalate), which must be removed from the product, increasing the multi-operation process and, therefore, the cost of the product, while draining into the sewage system requires an expensive treatment system.

A known method of obtaining a pectin-containing product from sea grasses of the Zosteraceae family, including drying raw materials, grinding, hydrolysis of raw materials with a solution of hydrochloric acid at pH 2.0-4.0 for 2-3 hours at a temperature of 50-60 ° C, washing with water until neutral , extraction of pectin with 0.5-1.0% sodium hydroxide solution for 3-4 hours, followed by neutralization of the plant mass with citric acid (see p. RU No. 2200424 C2, A23L 1/524)

The disadvantages of this method are: the complexity and duration of the technological process, the use of toxic chemicals (acids, caustic alkalis) and therefore the process cannot be considered environmentally friendly, while the product does not contain the entire complex of useful substances of sea grass.

The task is to create an effective method for processing the sea grass Zosteraceae to obtain products with a wide range of biologically active substances included in its composition with optimal processing parameters and environmentally friendly production.

The technical result is to expand the spectrum of biologically active substances of sea grass in the composition of the product.

The technical result is achieved by the fact that in the method of processing sea grasses of the ZOSTERACEAE family to obtain a product in the form of a powder, including grinding, drying, before drying, a mixture of crushed raw materials and water, taken in a ratio of 1: 1-1: 2, is cavitated, followed by evaporation of water at temperature 60-70 ° C to a moisture content of 4-6% and further grinding to form a powder with a wide range of biologically active substances of sea grass ZOSTERACEAE.

The technical result is also achieved by the fact that in the method of processing sea grasses of the ZOSTERACEAE family to obtain an extract, including grinding, extraction, before extraction, a mixture of crushed raw materials and water taken in a ratio of 1: 1-1: 2 is cavitated, followed by evaporation of water at a temperature of 60 -70 ° C to a moisture content of 25-30% and additional grinding to a size of 5-10 mm, and the extraction is carried out with alcohol with a strength of 80-96% at a temperature of 20-40 ° C with a ratio of alcohol to raw materials 1: 1-1: 2, in for 30 days, followed by filtration to separate the liquid fraction from the meal and to separate alcohol from the liquid fraction to obtain a concentrated extract.

The use of cavitation in the processing of sea grass, in which the ionic bonds of all useful components of sea grass are broken, as a result of which the components (a wide range of biologically active substances of sea grass) pass into a free form available for assimilation by the human body. Carrying out extraction with alcohol, that is, with a food extractor, after cavitation, at lower temperatures of 20-40 ° C, preserves biologically active components of sea grass without destroying, ensuring environmentally friendly production. The alcohol is separated and reused in production, reducing the cost of the product.

The method is carried out as follows.

The harvested seagrass of the Zosteraceae family is sent to production no later than 12 hours after its catch. During the acceptance process, the ingress of fresh water in the form of precipitation or from another source is not allowed. The delivered seagrass is placed in baskets or nets that are suitable for contact with food products, for example, made of stainless steel to free it from sea water. After the seawater drains off, the sea grass is sorted and cleaned, for example, manually to remove impurities in the form of shells, stones, various types of debris, as well as impurities of other types of sea grasses and algae.

The method of obtaining a product of processing sea grass of the family Zosteraceae in the form of a powder is as follows.

The peeled seagrass is crushed to a length of 5 cm to 10 cm using automatic and semi-automatic equipment. Crushed sea grass is poured with water in the ratio of raw materials: water 1: 1-1: 2, after which the process of cavitation of a mixture of water and raw materials is carried out.

In the process of cavitation, the ionic bonds of all the components of the sea grass are broken, micro and macro elements are released into a free form, available for assimilation by the human body. The aqueous mixture of raw materials after the cavitation process is placed in a drying chamber and the process of water evaporation is carried out at a temperature of 60-70 ° C, to a moisture content of 4-6%. After drying, the raw materials are crushed to a finely dispersed powder to obtain a product in the form of a powder with a wide range of biologically active substances of the sea grass ZOSTERACEAE.

The method of obtaining a product of processing sea grass of the family Zosteraceae in the form of an extract is as follows.

The peeled seagrass is crushed to a length of 5 cm to 10 cm using automatic and semi-automatic equipment. Crushed sea grass is poured with water in the ratio of raw materials: water 1: 1-1: 2, after which the process of cavitation of a mixture of water and raw materials is carried out, followed by evaporation of water at a temperature of 60-70 ° C to a humidity of 25-30%. The dry product is additionally crushed to a particle size of 5-10 mm, placed in a container for food production and filled with ethyl alcohol with a concentration of 80-96.3%, food grade with a ratio of alcohol to raw materials 1: 1-1: 2. The process of extracting raw materials is carried out at a temperature of 20 ° C to 40 ° C, provided there is no direct sunlight. Extraction time is not less than 30 days. During the extraction process, the mass must be stirred at least 2 times a day. At the end of the extraction process, the solution is filtered using, for example, fabric filters made of coarse calico folded in two layers. As a result of filtration, a liquid fraction and meal are formed. The meal goes for further drying. The liquid filtered fraction enters the alcohol distillation stage. The alcohol is distilled off using a rotary evaporator under artificial vacuum. Temperature parameters of alcohol evaporation should not exceed 50-55 ° С to preserve the entire spectrum of biologically active substances of sea grass. The process is completed only after the complete removal of alcohol from the extract. At the end of the alcohol evaporation process, two fractions are obtained: ethyl alcohol and a concentrated sea grass extract. Ethyl alcohol is reused in the extraction of raw materials.

The meal obtained after filtration is dried to a moisture content of 4-6%. For drying, thermal drying ovens and lyophilic installations are used. After drying, the meal is crushed to a finely dispersed powder and used in the production of food products, biologically active food additives, as well as animal feed, as the main and (or) auxiliary raw material.

The products of processing sea grass of the ZOSTERACEAE family in the form of powder or extract are used as an independent product, or for the production of other food products and medicines, as the main and (or) auxiliary raw materials.

The method of processing sea grass of the Zosteraceae family, which allows to obtain an expanded range of biologically active substances of sea grass in the composition of the obtained products in environmentally friendly production, will find industrial application.
