Ethnographic examples of stone-tool makers in Australia and archaeological examples from three different areas in the western United States indicate that the availability of lithic raw materials is an important variable conditioning stone-tool production technology. Attributes of availability such as abundance and quality of lithic raw materials condition the production of formal- vs. informal-tool types. Poor-quality raw materials tend to be manufactured into informal-tool designs. High-quality lithic raw materials tend to be manufactured into formal-tool designs when such materials occur in low abundance. When high-quality materials occur in great abundance both formal- and informal-tool designs are manufactured. Other factors, such as residential mobility or sedentism, are found to be less-important determinates of lithic-production technology.

A technology, based on the production of wine beverages from grape cryopowders in the mountain-valley zone of the Republic of Dagestan, is proposed. The data on the vacuum microwave drying of grape raw materials and subsequent grinding in a cryomill are presented. The modes of grape raw material preparation and its subsequent dehydration and cryo-grinding, which provide the possibility of successful use in the dried state in the production technology of wine drinks, are proposed. The principal feature is the use of whole grapes as a raw material, with rinds and seeds. The physical and chemical indicators, the content of phenolic substances and the organoleptic indicators of wine beverages made according to the traditional technology and the beverage made from grape cryopowders were studied. A comparative assessment of beverages was made. It is established that vacuum microwave drying conduces to better preservation of the properties of raw materials and finished products. The organoleptic assessment showed that the wine drinks developed according to the proposed technology had a more intense color and a more pronounced flavor of sweetness and sourness than traditional wine beverages. The advantage of this technology is the ability to transport grape cryopowders in unregulated temperature conditions to any point close to the consumer and carry out the production of wine beverages there.

The common food container product was made from plastic such as polypropylene, polystyrene, etc which has slowed to degrade hence affected to the environmental pollution and health disorder. Therefore, environmentally friendly food container composite is developed from sustainable resources such as sorghum bagasse and citric acid. The effects of sorghum species, sorghum particles and citric acid content on the composite properties were investigated. Local species of sorghum was used as raw material such as Super 2 in the manufacturing of food packaging.  The size and moisture content of the particles were passthrough on 40 mesh and 10%, respectively. The content of the particle was variated such as 10, 15, and 20% wt. Furthermore, citric acid was used as a binder with difference content such as 10, 20, and 30% wt.  Those raw materials were mixed with tapioca starch, polyvinyl alcohol (PVA), and glutaraldehyde. The mixing material was hot pressed at 180 ℃ for 15 minutes. The composite dimension was 12 cm x 10 cm x 3 mm. The physical and mechanical properties of the composite were carried out. Considering the properties of the composite, sorghum bagasse and citric acid are suitable as raw material of food container composite.

The growth in demand for gluten-free products linked mainly to health aspects has led to an increased interest in the production of mixed flours for use in bakery products. This work aimed to evaluate the use of different mixtures of cassava starch with banana flour, obtained from the pulp and peel of green fruits, for the production of gluten-free biscuits. In the preparation of the biscuits, seven mixtures were prepared with varying percentages of cassava starch, banana pulp flour and banana peel flour. A formulation with wheat flour was used as a control. Wheat flour, cassava starch and banana flours were analyzed for chemical composition. The results showed that the banana peel flour stood out for its higher levels of proteins, fibres, lipids, ash, total phenols, total flavonoids and antioxidant activity which make this flour effective as a functional additive. However, the results of physical and sensory characteristics of the biscuits showed that the variation in the percentage of banana peel flour led to greater changes in the quality attributes of the biscuits, so the percentage of inclusion should be limited. Banana pulp flour (UBF) had high starch content, however, the biscuits produced with higher percentages of this flour and lower percentages of cassava starch showed lower propagation rates, greater hardness and less sensory acceptance, showing the importance of the starchy raw material in the physical properties of biscuits. Formulations containing cassava starch mixed with up to 15% banana flour (1:1, pulp and peel) are a good basis for making gluten-free biscuits.

This article reflects the results of a set of studies on obtaining a face ceramic brick of soft molding with the search for raw materials and the development of an optimal production technology. It proposed and formulated the basic requirements for opoka-like rocks for the production of various types of wall ceramic products. They include recommendations on the chemical composition and such physical, mechanical and technological properties as density in the piece, natural humidity, porosity, mineral composition, compressive strength of the baked samples, fire shrinkage, water absorption, average density, etc. We proposed the so-called "soft molding" as a production technology. It is based on the principle of filling individual forms with a ceramic mass that has a certain plasticity and binding capacity. The appearance of such a brick is characterized by the absence of smooth edges and sides and rounded corners. The sand used for spilling forms produces a special effect of velvety and old-looking brick. The conclusions based on the results of laboratory and technological research as well as factory tests revealed the great promise for using opoka-like rocks as a raw material for the production of face ceramic bricks of soft molding.
