Abstract:

The article investigates the composition of the properties of various kinds of pentosan-containing raw materials germinating in the Republic of Uzbekistan. More than 15 types of plant raw materials germinating in Uzbekistan have been selected. Their composition was analyzed and their suitability as raw materials for the hydrolysis industry was determined. The yield of furfural and other products from the corresponding raw materials has been determined. It is shown that Uzbekistan has huge reserves of PSS, which are renewed annually on the territory of the Republic of Uzbekistan.

Abstract:

The article provides justification and development of the methodology for modeling the recipe composition of health food products based on functional compositions. The basis of the modeling is the principle of food combinatorics, which consists in the justified quantitative selection of the main raw materials and food additives, which together ensure the formation of the necessary organoleptic and physicochemical properties, the given level of nutritional (food, biological) and energy value. Modeling of food products is the process of creating a product as a single integrated system consisting

Bio-pellets are a renewable alternative energy source with great potential in Indonesia. This study made bio-pellets into two compositions with the raw materials used: coconut coir waste, rice husks, and sawdust. The composition of bio-pellet A was made in a ratio of 1:1:1, and the composition of bio-pellet B was made in a ratio of 1:0,5:0,5.

The progressive changes in ceramic raw materials during firing processes are a complex area. This is partly due to the large number of raw material characteristics, primarily mineral composition, and partly to the relatively inadequate particle distribution in the unfired clay body. The most important starting point is always the optimal raw material composition which should give appropriate physical and mechanical characteristics to the final products after firing processes and should provide an efficient and economical production.
