Development of technology of dry concentrate beverage based on pectin from sea grass<i> Phyllospadix iwatensis</i> with the addition of <i>Eleutherococcus senticosus</i> extract
The technology of obtaining a dry granulated beverage of functional purpose based on pectin from sea grass Phyllospadix iwatensis with the addition of eleutherococcus extract is presented. To increase the rate of dissolution of native pectin acid hydrolysis was carried out. In addition, sucrose was added to reduce the viscosity of the hydrolysed pectin and increase its solubility. A composition with a pectin content of 30 % was used in the work, so that the resulting beverage could be classified as functional. The quantitative determination of eleutheroside B in the beverage was carried out by HPLC with spectrophotometric detection at a wavelength of 266 nm. It was found that in the original extract of eleutherococcus liquid 0.272 % of eleutheroside B was contained, and in the finished functional beverage 0.003 %. The development of the beverage formulation was carried out in accordance with the requirements of State Standard of Russia number 28188-2014. The current regulatory documents of the Russian Federation (RD RF) and the countries of the Eurasian Economic Union assessed consumer properties. Organoleptic evaluation of the drink according to ISO 11035: 1994 and State Standard of Russia number 6687.5-86 was carried out, and the main physicochemical parameters (titratable acidity, humidity, mass fraction of dry substances and minerals) were determined. The drink with the addition of eleutherococcus extract had a tart flavor, inherent in eleutherococcus, which not only did not spoil the organoleptic properties of the drink, but also gave it some originality. According to the terms of storage, the drink was in accordance 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.
