Currently, the creation of a range of new products that improve human nutritional status is a timely and urgent problem facing scientists in the food industry. In food technology it is effective to use functional ingredients that have enhanced protective and improved technological properties. It is possible to confidently attribute the components of plant origin, namely, dietary fiber and plant phospholipids, to such substances. Phospholipids are a group of essential substances that are irreplaceable and enter the human body only with food. Phospholipids cannot be formed independently in the human body, but perform important functions that have a positive effect on the body: they restore cell walls; they are involved in lipid metabolism, as well as reducing the risk of cholesterol formation; they actively participate in the delivery processes of biologically active substances to cells, etc. A rich source of biologically active substances are flax seeds, its medicinal properties have been known for centuries and are recognized by official medicine. The influence of flax seed mucilage and phospholipids in the formulation of red main sauce on rheological and physical parameters was investigated. Samples of sauces with replacement of 50 and 100% of flour for flax polysaccharides and 30 % of animal fat for vegetable phospholipids were developed. The change of effective viscosity and density of the developed sauces is investigated. It was found that at a shear rate of 0.3333 s-1 the viscosity of the control sample is 14.32 Pa·s, of the same one with the replacement of 50 % flour and 10 g of fat and 100 % flour and 10 g of fat, respectively, is 16.49 and 19.6 Pa·s. This replacement in the experimental samples is accompanied by a slight increase in density. In order to substantiate the functional orientation of sauces in the introduction of herbal additives, studies were conducted to determine the antioxidant activity (AOA) of the developed sauces and their components. It was found that the maximum AOA a sauce with herbal additives has, which for 90 minutes is able to “quench” 89 % of the radicals formed in these conditions in the model system. Adding sauces to ready meals, even in small quantities, help to increase the nutritional value and attractiveness of the consumed food. Therefore, the effect of additives on the consumer characteristics of sauces was investigated. It is established that the developed types of sauces have a characteristic structure, creamy and homogeneous consistency, pronounced taste and aroma. The conducted complex of researches allows to state with confidence that use of available vegetable raw materials instead of the ingredients possessing the raised food value, allows to reduce energy value and to expand the range of sauces of functional orientation for restaurant enterprises.
