The purpose of this work is to justify the choice of wild plants of Kazakhstan (rosehip, sea buckthorn, hawthorn) based on the study of their chemical composition and safety, in order to expand the raw material base and the possibility of using them in the technology of functional foods. As a result of the study of the chemical composition of hawthorn, rosehip and sea buckthorn fruits it was found that the content of vitamin C in hawthorn fruits is 27.8 mg, in rosehip fruits - 578.01 mg, in sea buckthorn fruits - 285.05 mg per 100 g of product. The content of vitamin E is 7.8; 1.8; 3.18mg, β-carotene - 9.27; 2.7 and 2.13 mg, dietary fiber - 7.2; 12.28; 2.24 g. The content of potassium in hawthorn fruit is 14.72 mg, in rosehip fruit - 26.18 mg, in sea buckthorn fruit - 197.18 mg per 100 g of the product. The iron content is 0.05; 1.7; 1.14 mg, Zn - 0.08; 0.23 and 0.004 mg, respectively. According to safety indicators, the studied plants meet the requirements of the regulatory documents. As a result of research on the nutritional value and safety of fruits of wild plants, the expediency of using them in the production of functional food products has been substantiated.
