The purpose of present work is the development of formulation and evaluation of syrups consumer properties with the addition of an extract of marine green algae. As a basic commodity syrups based on syrups from the aqueous extracts of rosehip, lemongrass, hawthorn were used. The development of formulations syrups was carried out according to State Standard of Russia number 28499-90. The consumer properties of experimental syrups were evaluated by the current regulatory documents of the Russian Federation (RD RF) and the countries of the Eurasian Economic Union. Sensory evalua-tion of syrups was carried out according to State Standards of Russia number 6687.5-86, ISO 11035: 1994; mass fraction of dry substances in accordance with State Standard of Russia num-ber 6687.2-90; titratable acidity was according to State Standard of Russia number 6687.4-86. The safety indicators of syrups were studied according to TR CU 021/2011. Indicators of quality and safety developed syrups meet the requirements of the RD RF and the EAEU. Syrups with addition of the Ulva extract, were more dense than control samples, had faintly expressed algal taste which did not just spoil the organoleptic properties of products, but also gave them some originality. According to the terms of storing all syrups which meet the requirements of State Standard of Russia number 6687.6-88. Indica-tors of titratable acidity of all the studied indications of syrups were in accordance with State Standard of Russia number 6687.4-86, but slightly higher of acidity from syrup with lemongrass, which depend-ed on natural feature of the base component. Safe-ty indicators of the studied syrups meet the re-quirements of TR CU 021/2011. In the Ulva's ex-tract and syrups with it, the toxic elements were found, but in acceptable quantities of standard documentation. Thus, the study shows the absence of technological risks of water-ethanolic extract of seaweed Ulva using as a new ingredient in syrups based on native raw material of the Far East. Re-ceived positive results of consumer properties syr-ups evaluation, their quality, safety, proven by sci-entists hepatoprotective effect of the extract from marine green algae, determine the prospects of its application (with additional research) as a function-al ingredient.
