Description

Inventors relate to food production about 1,:} stnos and fuschie dye technology from vegetable raw materials

There is a known method of sticking green ил h о o from shredded dry, pepper, two-fold O2 abstraction with ethanol, filtering and (centrifuging by distilling off ethanol to a dry matter content of 0 83 - 0 85%, followed by extraction with vegetable matter

This method is complex with a TDS, as it provides for 3 extraction of airborne dust obtained by this method is relatively expensive due to the use of vegetable oil as extractants and

Most likely, a half-edged green food dye method involves a 3-fold extraction with ethanol of the crushed mass of tomato plants or a pumpkin family after each stage, followed by mixing the filtrates, concentrating the mixture and settling the sediment and adding acetone with stirring and separating the extractor. evaporation until acetone is removed; mixing of the evaporated mass with precipitate and drying

This method is complex (includes 14 operations) is long (11 5 1 bh), which affects the cost of dye

The chain of the invention is to simplify the method of reducing the cost of the final product and expanding the functionality of the method

With this CRT, when implementing a method of populating a green food dye involving the extraction of ground green mass of tomato or pumpkin oats with a solvent filter: and drying, the extraction of ground green mass is carried out simultaneously with squeezing the juice and then separating it from the meal, water is used as bodies green mass. water 11-115 after filtration HarpeaeiKrf extract Up to 80-90 ° С the liquid is decanted and the solvent is precipitated

The sucker is dried, while the UIDOT is extracted with ethanol at a ratio of 1: 2 for 30-40 minutes, the extract is filtered, dried under an azum and mixed with dried sediment, and the decanted liquid is concentrated to a dry matter content 78 80% ..,

Example 1. 1000 kg of freshly harvested green mass of cucumbers were crushed {passed a cutting machine through m), loaded into a screw press, poured 1000 l of water and squeezed juice, and the meal was removed. The pressed juice was filtered, the filtrate was heated to 80 ° C. at the same time, the chlorophyll mass floated up, and the decanted liquid was poured into a separate vessel. The precipitate was dried, got 15.4 kg of dry green dye. The separated meal was poured in two times the amount of ethanol, extracted for 30 minutes, filtered and dried under vacuum to regenerate the step. Received additional 14.2 kg of dry green hrssitel

The decanted colorless liquid was concentrated to a dry substance content of 78%, and an amber-colored concentrated mass of 72 ml was obtained.

EXAMPLE 2 1000 kg of freshly green green mass of tomatoes were crushed, loaded into a shake press, poured 200 l of water and squeezed out juice. and the meal was removed. Pressed juice was filtered, the filter was heated. up to 85 ° C with a print, chlorophyll surfaced, the liquid was decanted, and the precipitate dried out and obtained 17.3 kg of dry green dye. Separated meal was washed down with twice the amount of ethanol, extracted for 35 minutes. filtered and dried under vacuum until the liquid was completely removed; 16.5 kg of dry green dye was obtained additionally; Decanted liquid was concentrated to a dry matter content of 79%. received an amber-colored syrupy liquid in the amount of 64 ml.

PRI me R 3. 1000 kg of freshly bred green pumpkin were crushed, a screw press was loaded, 1500 l of zod was poured and squeezed. filtered, the filtrate was heated to 90 ° C. the liquid was decanted. Osade dried and obtained 14.8 kg of dry green dye. Separated meal (compressed juice pressing) was poured with two times the amount of etamope, extracted 40

m shh, filtered, “we sewed under vacuum and obtained an additional 13.1 kg of dry food green dye.

The decanted liquid was concentrated to a dry content of 80% and 58 ml of an amber-colored syrupy liquid were obtained.

Example 4. 200 kg of green mass of cucumbers crushed, loaded into a screw press, poured 200 liters of water and squeezed juice. filtered, the filtrate was heated to 78 ° C. however, chlorophyll did not surface. The experience stopped.

When the temperature rises above 90 ° C, the biologically active components included in the composition of the scoop.yoi active properties:

The dyes obtained by the proposed method are half the price of the dye according to the prototype method and can be used in the production of soft drinks and confectionery, as well as lotions and slippers of toothpastes and the like. And amber syrup-like liquid is used in perfumery and cosmetics D1z of nutrient preparation compositions, for example, skin creams, as well as in microbiology as a nutrient medium for growing microorganisms.

P-rmula of the invention

A method for producing a green food dye, which involves extracting crushed green mass of tomato; x i, i i t y k z nn y x grow with solvent, filtering and drying, due to the fact that. in order to simplify the process, the cost of dye and cost-saving functionality of the method. extraction of crushed green mass is carried out simultaneously with squeezing the juice and its subsequent separation from the meal; water is used as a solvent in the ratio of zylens mass to 1: 1-1 1.5. after filtration, the extract is heated to 80 -90 ° C. the liquid is decanted, and the resulting precipitate is dried. moreover, the separated meal is extracted with ethanol at a ratio of 1: 2 for 304-40 min, the extract is filtered, dried and mixed with dried precipitate. The dry liquor is dried to a dry matter content of 78 -80%.
