Development of technology for obtaining lycopene-containing dry powder from tomato pomace
Abstract
The development of an effective technology for obtaining lycopene-containing dry powder from pomace of zoned tomato varieties, for the purpose of enriching food products, has novelty and significance for the country, since lycopene is not produced in Kazakhstan. This technology has the potential to have a beneficial effect on people's health, labor productivity and the development of the state's economy. As a result of the study, the quantitative yield of tomato powder from tomato pomace was determined, drying modes were compiled, including temperature and drying time. The obtained samples of lycopene-containing tomato powder were analyzed for nutritional value, including proteins, fats, carbohydrates, vitamins, micro- and macroelements. At the same time, special attention was paid to the content of lycopene, a strong antioxidant present in tomatoes. The aim of the study was to develop a technology for obtaining lycopene-containing dry powder from the pomace of zoned tomato varieties for food purposes with a natural health effect and to study its qualitative indicators. During the work, the yield of dry lycopenecontaining tomato powder from tomato pomace was determined in the samples, which was at the level of: 6.0-6.1 ± 1.0%. The drying modes (drying temperature, drying time) of tomato pomace have been worked out. In the resulting tomato powder, nutritional values were determined: proteins – 15.83 g / 100g, fats – 9.3 g / 100g, carbohydrates – 51.89 g /100g. The study showed that tomato powder contains a significant amount of lycopene, along with other important vitamins and trace elements such as vitamin C, vitamin E, vitamin B2 and beta-carotene. It is also noted that toxic substances in tomato powder do not exceed the permissible norm, which confirms its ecological purity. Based on the results obtained, an optimal technology for obtaining lycopene-containing dry powder from tomato pomace, suitable for enriching food products with a natural health effect, has been developed.
