Разработка технологии сухого концентрата напитка на основе модифицированного пектина с добавлением дикоросов Дальнего Востока

Разработана технология и рецептура сухого концентрата напитка, содержащего функциональные ингредиенты: гидролизованный пектин из Phyllospadix iwatensis, элеутерозиды, флавоноиды, аскорбиновую кислоту. Определены дозы всех ингредиентов с учетом норм суточного потребления. Исследован процесс гранулирования композиции пектина и сахарозы с добавлением экстрактов элеутерококка, шипов-ника и боярышника. Содержание пектина, элеутерозидов и аскорбиновой кислоты в однократной дозировке напитка (10 г) составляет 100 % от адекватного суточного уровня потребления, а флавоноидов – 20,5 %. Проведена органолептическая оценка напитка и определены его основные физико-химические показатели. Исследованы показатели безопасности сухого концентрата напитка. The technology of obtaining a dry concentrate of a functional beverage based on hydrolyzed pectin from sea grass Phyllospa-dix iwatensis with the addition of extracts of eleutherococcus, rosehip and hawthorn is presented. In order to classify the bev-erage as a functional, we used a composition containing 20% pectin. Quantitative determination of eleutheroside B and ascor-bic acid was performed by HPLC with spectrophotometric detec-tion at 270 nm and 243 nm, respectively. The quantitative con-tent of the total flavonoids (in terms of rutin) was determined by the spectrophotometric method at a wavelength of 406 nm. To improve the organoleptic characteristics, citric acid, stevioside and elderberry extract were added to the beverage. The formula-tion of the beverage was developed in accordance with the requirements of the State Standard of Russia number 28188-2014 and the norms of daily consumption. Consumer properties were assessed according to the current regulatory documents of the Russian Fed-eration (RD RF) and the countries of the Eurasian Economic Union. The organoleptic evaluation of the drink was carried out in accordance with ISO 11035: 1994 and State Standard of Russia number 6687.5-86, the main physical and chemical indicators (titrated acidity, humidity, mass fraction of dry substances and minerals) were determined. The resulting beverage has a sweetish taste and a pleasant berry aroma with a pronounced rosehip smell. According to the terms of storage, the drink was in ac-cordance with State Standard of Russia number 6687.6-88. The main standard indices of the safety of the drink according to TR CU 021/2011 - the content of heavy metals, microbiological indices. The quality and safety indices of the developed product corresponded to the requirements of the Russian Federation and the EAEC.
