Abstract
The study of functional ingredients to change the composition of water-soluble vitamins in the developed pastille of marmalade products was studied. The large concentration of riboflavin, nicotinic acid, pantothenic acid, folic and ascorbic acids, pyridoxine was observed in the sample with the addition of 1% Hypericum, which shows that the high content of these vitamins in the herb (Hypericum olympicum). The vitamin composition of marmalade samples with the addition of various functional oils has been studied. In these samples, as in the control sample, thiamine chloride was not detected, which is supposed to be due to the influence of technological processing modes when obtaining oils. According to the content of riboflavin, nicotinic acid and pantothenic acids, the sample with walnut oil prevailed, corresponded to 0.06, 0.011 and 0.12 mg/100 g. In the sample with Hypericum oil, 0.011 mg/100 g of nicotinic acid and 0.1 mg/100 g of pantothenic acid were found more. The sample with milk thistle oil contained more riboflavin 0.068 mg/100 g, pyridoxine 0.158 mg/100 g, folic acid 0.08 mg/100 g. There was more ascorbic acid in the sample with the addition of Hypericum oil and amounted to 0.145 mg/100 g. According to the results of a comparative analysis of water-soluble vitamins, it is recommended for use in the preparation of marmalade products: Hypericum in the form of a herbal component, including in combination with aerial parts of sea buckthorn; oils of walnut plants, milk thistle, Hypericum wort, sea buckthorn.
