The growth of the cultivation and processing of citrus fruits is accompanied by the formation of a large amount of waste, which contains a number of useful nutrients and can serve as a valuable biological resource for various fields of application. The vitamins, trace elements, dietary fibers present inthe composition allow you to use them as effective functional additives. The specificity of citrus dietary fibers is a large amount of protopectin, which determines their significant sorption properties. The ability of fibers to retain water makes them effective thickeners and attractive components of low-fat emulsion products, such as mayonnaise sauces. The article presents the results of a study of the properties of powders obtained from dried grapefruit and orange peels by grinding and dividing into fractions by sieving through sieves of different diameters. The indicators of the moisture-retaining capacity of grapefruit and orange powders, their blends and mixtures with coconut flour were determined. The stability of low-fat emulsion products obtained with the addition of the indicated additives in the amount of 5% to the recipe was studied.The introduction of grapefruit and orange powder additives into the low-fat mayonnaise sauce recipe will enrich them with dietary fibers, give a piquant taste and aroma, and contribute to the formation of a product with proper rheological properties and consistency.The analysis of research and publications showed that among the hydrocolloids used in the production of low-fat mayonnaise products, a special place is occupied by dietary fibers of citrus fruits with a high index of moisture retention capacity, which is higher than that of fibers from other raw materials, for example, carrots or oats. Considerable attention is paid to orange pulp powder products with a balanced content of soluble and insoluble dietary fibers, which serve as effective additives capable of retaining moisture and forming low-fat products with a thick consistency.The purpose of the article is to study the properties of grapefruit peel powder and its mixtures with other functional additives for low-fat mayonnaise sauces; determination of their moisture retention capacity; production and stability research of low-fat mayonnaise sauces based on them.For different size fractions of dried and crushed grapefruit and orange peel, indicators of moisture retention capacity were determined. It was established that this indicator has a larger value for the smallest fraction. For grapefruit powder with a particle size of less than 0.50 mm, the moisture retention capacity is 808%, and for orange -591%. A mixture of grapefruit and orange powder with different ratios of components was also found to have a high ability to retain water. Properties of mixtures of citrus powder and coconut flour were studied. Made samples of low-fat mayonnaise sauces with the addition of individual and complex functional additives in the amount of 5%. The effectiveness of their action was checked by determiningthe stability index of the manufactured emulsion products, which met the requirements set for mayonnaise and mayonnaise sauces by the current standard
