Description

The invention relates to the food industry. A known method for the preparation of carotenoid preparations by repeated extraction of the skin of tomatoes with dichloroethane, condensation of the extract, followed by distilling off the solvent: in a vacuum and separating the ballast materials fl. The disadvantages of this method are the low quality of the product as well as the presence of tocopherone or hydroquinone in the resulting preparation. The purpose of the invention is to improve the quality, increase the yield and expand the raw material base. The goal is achieved by the method of obtaining carotenoid preparation by repeated extraction of tomato skin with dichloroethane, condensation of the extract followed by distillation of the solvent in vacuum and separation of ballast substances, as a raw material used are spreading marigold flowers, calendula flowers, and sunflower petals, before extraction from they extract the essential oil, the extraction of dyestuffs from the resulting waste is carried out simultaneously on the extraction of the skin of tomatoes, while the ratio of raw materials and dichloroethane is set to 1:10, and to remove the ballast substances, alumina is added to the resulting mass in a 1: 1 ratio, a. then elute with acetone, followed by distillation. Example 1. Fresh crushed flowers of spreading marigolds (Tagetes pa tula L.) are poured with water and the essential oil is distilled according to the Ginzburg method. In the process of distillation, simultaneously with the accumulation of essential oil in the Ginzburg tube, water-soluble flavonoids are transferred into the water. The water is drained and the remaining waste is dried to an air-dry state. The extraction of carotenoids is carried out by extraction of the crushed dried raw material after the distillation of the essential oil with organic solvents (for example, chloroethane). 1 kg of the dried raw material is extracted 4 times with dichloroethane in the ratio of 1:10 to the weight of the raw material at 18-20 s. The duration of the first, second, third and fourth extraction is 30 minutes each. Dichloroethane extracts are combined, total volume 40 liters. The resulting extract

distilled off under 80-90 mm Hg at 40-45 s to obtain a pasty product (ml), which contains mainly carotenoids and a small amount of ballast substances: flavonoids in the form of glycosides and aglucones, wax. To remove the ballast substances, alumina in ratios of 1: 1 to 200 g (of any activity) is added to the pasty product and mixed. The resulting mass is transferred to a chromatographic column of size cm, filled with alumina in an amount of 300 g. Carotenoids are eluted with 3 liters of acetone for 5 hours. At the same time, the carotenoids are completely washed out of the column. Acetone is distilled off to obtain a pastos carotenoid preparation. The total yield of the amount of carotenoids from 1 kg of air-dry material is 6%.

The resulting target product is a dark orange color, odorless and contains almost no impurities. Carotenoids should be stored in a dark glass container, hermetically sealed, in a cool place. The obtained target product is not toxic.

Example 2. Essential oil is preliminarily distilled off from freshly crushed calendula medicinal flowers (Calendula officinalis L.) in a known manner, and dyestuffs are extracted from dichloroethane 4 times in obtained ratios in ratio 1:10. Further processing of the raw material after the distillation of the essential oil and extraction with dichloroethane is carried out analogously to example 1.

The total yield of the sum of carotenoids from 1 kg of air-dry material is 4.7%. The resulting target product is bright orange, odorless and does not contain any impurities. The obtained target product is not f toxic. Pharmacological studies have established that the dye obtained from calendula is completely harmless and can be used in food industry.

Example 3 Essential oil is distilled off from freshly crushed sunflower petals (Helianthus annuus L.)

Q method and from the resulting waste dyes are extracted with dichloroethane 4 times in a ratio of 1:10. Further processing of the raw material after the distillation of the essential oil and extraction with dichloroethane is carried out analogously to example 1.

The total yield of the sum of carotenoids from 1 kg of air-dry material is 11%. The resulting target product is yellow-orange in color, odorless and contains no impurities. The product is non-toxic and is approved by the State Pharmacopoeia.

Example 4. 1kg of air-som5 of chopped tomato skins, which are non-edible waste of tomato-canned production, are poured. dichloroethane and extraction of the colorants was carried out analogously to example 1.

1 Due to the absence of essential oil in the used waste, the process of distillation of essential oil falls out. Further processing of the raw materials is carried out according to the method described in Example 1.

The total yield of the sum of carotenoids from 1 kg of air-dry material is 251.7 mg or 0.252%. Half- The target product is dark orange, odorless and does not contain any impurities.

The table shows the results obtained for the proposed and known methods.

6 The invention is of interest to the national farm. The use of the proposed method in canning as well as in specialized carotene plants will make it possible to discontinue such valuable products as carrots and pumpkin. / To obtain the sum of carotenoids by the proposed method, it does not take much time, special equipment and the use of a significant amount of reagents. As a result of the preparation of the carotenoids preparation by the proposed method, their quality is improved and the yield is increased. The invention of the method of obtaining carotenoids by repeated extraction of the skin of tomatoes with dichloroethane, cr the extract of the extract with the subsequent distillation of the solvent in vacuum and the separation of ballast substances, characterized in that raw materials. in addition, they use flowers of marigolds of rakaki thistyas, flowers of coiled calendula and petals. Before extraction, essential oil is extracted from them, extraction of the beautiful substances from the resulting waste is carried out simultaneously with extraction of the cutters; 1: 1, and then eluted with acetone followed by distillation. ° Sources of information taken into account in the examination 1.
