There is an interest in sweet dishes such as aerated desserts, which are gaining popularity among consumers. Raw materials of plant origin, used in the technology of aerated products, are intended mainly to improve their quality characteristics. Especially for enrichment with protein substances, micro and macro elements, vitamins, as well as to obtain a product rich in dietary fiber content. In the segment of aerated dessert products, a distinctive feature of which is the multistage of the production process and the need to use special equipment, technologies involve the use of foam and structure-forming food additives. For the formation of a whipped and stable structure, as well as the addition of surfactants that can cover the surfaces of bubbles and prevent their coalescence, food additives of various origins are used. Therefore, it is relevant to investigate the foaming ability and stability of aerated desserts and improve the technological parameters of the processes or foam structures of desserts. It is necessary to take into account the structural and mechanical properties of aerated dessert products, which are the main characteristics of the quality of aerated desserts. Thus, it is relevant to devise technologies for aerated desserts and food additives in their composition, which will serve as a stabilizing agent, as well as a dietary supplement. A recipe for aerated dessert – mousse based on fermented milk cheese with the introduction of a complex additive into the recipe – was developed. The optimal amount of food additive in the composition of aerated dessert, which is 3 % of the recipe composition, has been established, which will ensure the stability of the food system of aerated products, in particular mousses. The influence of the additive on the structural and mechanical properties of the food system of dessert has been investigated. The experimental data could be used for improving technologies for the production of aerated desserts.

Background. An important problem of modern society is to provide the population with food products that guarantee a higher standard of living and health. The field of HoReCa (hotel and restaurant business) does not sell enough healthy food products, therefore it is important to develop health-promoting food products. Among the wide range of food products, whipped dessert products are in great demand among consumers. The work is devoted to the development of formulation for aerated desserts, namely mousses of protective action, which have pronounced ergogenic properties that can increase efficiency, accelerate recovery, protect the body from stress. When developing the composition of mousses, we paid considerable attention to the study of the nutrient composition of the raw material, its changes during the technological processes of product development. The devepoled mousse formula includes the food additive collagen hydrolyzate the functional property of which is the renewal of intra-articular fluid and the construction of cartilage. Also, the collagen hydrolyzate promotes collagen production and can also be used to prevent the development of degenerative conditions of the musculoskeletal system. Objective. We aimed to design formulations for the production of protective mousses with the optimal ratio of basic nutrients and by supplementation with an additional component – collagen hydrolyzate – to increase the nutritional and biological value of finished products, as well as to expand the range of health food products, in particular aerated desserts. Methods. We optimized the mousses formulation taking into account the recommendations for the daily human need for the main macronutrients using mathematical modeling employing MS Excel. The qualitative and quantitative composition of microbiota during storage were analysed in accordance with DSTU 4503:2005 "Cheese products. General technical conditions". The organoleptic evaluation was performed using the sensory method on indicators according to DSTU 3718:2007 "Food concentrates. Sweet dishes, jellies, mousses, puddings, milk concentrates. General technical conditions". High-performance liquid chromatography was used to determine the micronutrient content. Results. We analysed such indicators of mousses as amino acid score and macronutrient content. The study of the amino acid composition showed that the consumption of 100 g of mousses "Cream-cheese" and "Strawberry" satisfies the daily human need in valine by 12.97% and 5.93% respectively. The developed products have a high content of all essential for the human body micronutrients, namely sulfur, calcium, phosphorus and potassium. We found that the shelf-life of mousses is 5 days at the temperature of 5 ± 1 °C in a glass container. Such microorganisms as bacteria of the Escherichia coli group, Staphylococcus aureus, Salmonella spp. were not detected during the entire shelf-life, that meets the requirements of regulatory documents and indicates the sanitary cleanliness and safety of the products. We have experimentally established the rational amount of collagen hydrolyzate food additive that is 3% by weight of the prescription composition of the product. Conclusions. We developed the mousse formulations comprised the supplement of a food additive of collagen hydrolyzate, which made it possible to obtain products balanced in biological value and with improved consumer properties, taking into account the norms for a person's daily need for basic macronutrients. We obtained products of high consumer quality and biological value by supplementation the recipe composition with a collagen hydrolyzate.

Переробка промислових риб супроводжується утворенням вторинних ресурсів, область практичного застосування яких досить широка (рибні білки є унікальним природним матеріалом, що застосовується в різних галузях промисловості – харчової, мікробіологічної, медичної та ін.), але не використовується повною мірою. Відходи, що утворюються в результаті переробки риб, є джерелом цінних харчових та біологічно активних речовин, внаслідок чого служать сировиною для отримання різних продуктів, у тому числі й біологічно активних добавок. Метою статті є аналіз технологій переробки, методи виділення та отримання продуктів з вторинної рибної сировини. Сучасне виробництво рибопродукції супроводжується великою кількістю білокмісних відходів, що становлять від 30 до 70% від маси вихідної сировини. Науковцями розроблено ряд технологій виділення колагену та переробки рибної сировини. Розвиток теоретичних і практичних основ технологій в умовах раціонального використання основних і вторинних ресурсів рибного походження актуально в умовах чинної екологічної напруженості і проблем дефіциту вітчизняних аналогів високотехнологічних матеріалів на основі білків сполучних тканин гідробіонтного походження. Білокмісні відходи характеризуються високими поживними властивостями, є джерелом колагену та продуктів його гідролізу, які отримають за допомогою хімічного та ферментативного гідролізу. Традиційні технології не є ефективними, тому науковцями запропоновано інноваційні методи та технології отримання протеїнів, які в свою чергу будуть меншою мірою впливати на вихідні властивості продуктів, виділених з вторинної рибної сировини. М’ясо гідробіонтів багате на незамінні амінокислоти, вітаміни, мікроелементи і є повноцінною сировиною для виробництва харчових білкових гідролізатів та найбільш цінним джерелом протеїнів з економічної та екологічної позицій. Пошук нових технологій – актуальне завдання, зважаючи на все більше використання рибного колагену.
