STUDYING THE PROSPECTS OF USING PINEAPPLE WASTE RAW

Abstract

The problem of expanding the range of herbal medicines can be solved through the use of plant objects traditionally used in the food industry, characterized by the presence of a wide range of pharmacological activity, and the most promising raw materials are processing waste, in terms of the content of biologically active substances (BAS), not inferior to the pharmacopoeial vegetable raw materials, which allows you to create waste-free processing technologies, covering both the food and pharmaceutical industries. A promising crop from this point of view is pineapple fruit, the production and consumption of which in the world is increasing every year. To date, the global pineapple market has grown to $14.9 billion, approximately 26.4 million tons. Purchases of pineapple seeds to Russia are constantly increasing. According to the Agrobusiness expert and analytical center, pineapple supplies in Russia increased by 23.7% by 2022 and amounted to more than 11 thousand tons. In recent years, the study of the chemical composition of infructescences and the features of their pharmacological action, including in systemic metabolic disorders and oncology, has attracted significant interest from researchers. At the same time, pineapple seedlings in the Russian Federation are not pharmacopoeial raw materials. Significant waste from the processing of seedlings in the food industry is disposed of. The aim of the work is to study the yield of products remaining after processing pineapple fruits of different varieties, followed by a preliminary phytochemical analysis of leaves and pulp of pineapple fruits and an assessment of the prospects for their further study. The authors, using gravimetric analysis, revealed the amount of waste represented by leaves, peel and pulp of peeled fruits after mechanical squeezing of juice for pineapple varieties mainly purchased in the Russian Federation. To determine the preliminary qualitative composition of pineapple processing products, a set of qualitative phytochemical reactions, most often used in pharmacopoeial analysis, was carried out with aqueous extracts from pulp and leaves of processed raw materials. The analysis confirmed the presence of substances of polyphenolic nature, amino acids and vitamins in the raw material. According to the authors, further study of pineapple fruit processing waste is an urgent and promising area of pharmaceutical research.
