Determination of Commodity Characteristics of Emulsion Based on Low-methoxylated Pectin for Dishes of the «Eat Healthy» System in the Restaurant Service

The object of research is emulsions based on low-methoxylated apple pectin for dishes of the «Eat Healthy» system in the restaurant industry. The subject of the research is the commodity characteristics of emulsions for dishes of the «Eat Healthy» system. In the course of the study, methods were used to determine commodity characteristics based on sensory and physicochemical analysis. The proposed ingredient composition of emulsions based on low-methoxylated apple pectin makes it possible to form not only high consumer qualities, but also to provide the target product with functional health properties. The sorption activity of pectin makes it possible to bind and remove heavy metals, radionuclides from the body; removal of strontium isotopes has a high activity. As a highly hydrophilic, biocompatible biopolymer of plant origin, it provides a high viscosity of the structure at low concentrations, has a pronounced neutral, pleasant sour taste. Low-methoxylated apple pectin is one of the most common hydrocolloids, which is used in the technology of products with therapeutic, prophylactic, sorption, bactericidal properties. In addition, low-methoxylated pectin substances are a harmless and economical material, and can be considered as an alternative to antibiotics and synthetic preservatives to prevent bacterial spoilage and extend the shelf life of health food for public catering with high consumer properties. The influence of the technological properties of low-methoxylated pectin in the formation of commodity characteristics for food products based on emulsions in healthy food products of restaurant establishments of different styles and concepts has been determined. Samples of food emulsions were studied using different amounts of low-methoxylated pectin as a stabilizer to obtain a sedimentation-stable emulsion system. The use of low-methoxylated apple pectin in the composition of food emulsions increases the aggregate stability of the product, functional and merchandising characteristics. On the basis of a complex quality indicator, the optimal parameters of the emulsion formulation were determined. High-quality consumer characteristics are ensured due to the size of uronic particles up to 0.78–0.81 μm in size

Determining the Efficiency of Spontaneous Sourdough for Stabilizing the Quality of Bread Products in Bakeries and Catering Enterprises

Old baking traditions have been analyzed from the point of view of improving the technologies, assortment, and quality of bread products in modern enterprises of bread and restaurant business. Considerable attention has been paid to the problems that impede the introduction of spontaneous sourdough technology. The expediency of forming the theoretical basis of such technologies, specifying the requirements for raw materials, semi-finished, and finished products, and harmonizing the terminology, technologies, and regulatory documents accepted throughout the world has been emphasized.The expediency of studying the authentic Ukrainian spontaneous wheat sourdough (hop and wine yeast), as well as traditional Caucasian pea-anise sourdough, has been substantiated.The significant effect of formulation and properties of raw materials on the quality of sourdough has been established. It has been proven that sourdough acquires the required quality within 1–3 days when using wine yeast in the dilution cycle. Hop sourdough requires 7–8 days for fermentation, and pea-anise sourdough requires 15 days. Sourdough has general and specific properties: fermentation ability and acidity, special sensory and biotechnological properties, and microbiological composition. This affects the course of the technological process and requires adjusting the parameters of fermentation and sourdough bread preparation. Good sensory characteristics are typical for bread made with spontaneous sourdough. The ability of sourdough to inhibit the staling of products and prevent microbiological damage has been shown. It has been established that hop and pea-anise sourdoughs are stable for 90 days and wine yeast sourdough for 30 days of propagation.The obtained results give grounds for asserting the prospects of using spontaneous sourdough in bakeries and catering enterprises. This could be the basis for developing recommendations for problem solving and forming high-quality products and expanding the range of modern industrial and craft enterprises
