Abstract
In Russian Far East, one of the types of plant raw materials, which exhibits high antioxidant activity, is fireweed (Chamerion angustifolium). We studied the safety of this raw material and a tea drink produced from it. The studies were carried out in the period 2021–2023. Aqueous extracts of Dahurian rose hips (Rosa davurica), cranberries (Vaccinium vitis-idaea) and sea buckthorn (Hippophae rhamnoides) were used as additional raw materials. We herein present the data on microbiological contamination study and hygienic indicators of the safety of used plant raw materials, the duration of safe storage of the finished drink based on fireweed, as well as the compliance of raw materials and products with the requirements of regulatory documentation, including Technical Regulations of the Customs Union “On food safety” 021/2011.
