Abstract

The aim of the work is the development of a new way of deep processing of chlorophyll-containing vegetables that gives a possibility not only to preserve chlorophylls a and b and other biologically active substances (BAS) of raw materials, but also to transform hidden bound (inactive) forms of chlorophyll in the free easy-digestible form at getting steam-thermally processed semi-products and healthy food products in the nanoform.For achieving the aim, the complex effect of steam-thermal processing and mechanolysis at fine-dyspersed comminution using the new equipment was applied as an innovation for thermal processing and comminution.There was developed the new method of getting healthy products of chlorophyll-containing vegetables (broccoli, spinach, Brussels cabbage, green leguminous haricot bean), steam-thermally processed (by hot steam) in the steam-convectional stove and fine-dyspersed with high contents of chlorophylls and other BAS and prebiotics. The method is based on the complex effect of processes of thermodestruction, mechanodestruction and non-enzymatic catalysis on raw materials at fine-dyspersed comminution. It was demonstrated, that at steam thermal processing of chlorophyll-containing vegetables (CCV) in the steam-convectomat during 5 minutes, there takes place not only preservation of chlorophylls a and b, but more full separation (in 1,33…1,4 times) from the hidden (bound) form, comparing with fresh vegetables. There was elucidated the mechanism of this process. The more full extraction of hidden forms of β-carotene (2 times more than in fresh CCV) takes place in parallel.The essentially more effect of transforming hidden forms was revealed at fine-dyspersed comminution of steam-thermally processed CCV. It was demonstrated, that thermally processed nanoproducts of CCV contain 2…2,1 more chlorophylls a and b, 2,0…3,3 times more carotenoids in the bound form than fresh vegetables.The quality of obtained new types of fine-dyspersated steam-thermally processed green products as puree and soups-purees of CCV exceeds one of known analogues by contents of chlorophylls a and b, β-carotene and other BAS, which are in nanosize easy-digestible form.Using new types of fine-dyspersated purees of CCV, there was developed the new green line of healthy nanoproducts: soups-purees, nanodrinks, nanosorbets, sauces-dressings, sauces-deeps, ice-cream, snacks and so on. It was demonstrated, that new products exceed existing analogues by BAS content (chlorophylls, β-carotene, L-ascorbic acid, phenol compounds).
