nut oil was extracted from (black, brown and yellow) cultivars using n-hexane. Physiochemical properties (refractive index, specific gravity, acid value, free fatty acid, peroxide, saponification and iodine values of the oil samples were determined. Storage studies on the tiger nut oils were done by monitoring changes in the thiobarbituric acid, peroxide value, free fatty acid and moisture content for twelve (12) weeks. The refractive index, specific gravity, acid value and free fatty acid value ranged between 1.46 ̵ 1.47, 0.89 ̵ 0.90, 0.4 ̵ 1.40mg/g, and 0.20 ̵ 0.75% respectively. The peroxide, saponification and iodine values ranged between 3.99 ̵ 4.43meq/kg, 183.25 ̵ 202.87mg/kOH/g and 29.69 ̵ 31.74g/l2/g respectively. The major fatty acids (FAs) of the tiger nut oil were oleic (77.71%), palmitic (16.17%), and stearic (5.08%) acids for the black cultivar, oleic (64.12%), palmitic (11.86%), linoleic (11.87%) and dihum ̵ g ̵ linolenic (1.71%) for the brown cultivar while the yellow cultivar had oleic (68.89%), linoleic (12.77%), palmitic (13.33%) and stearic (4.46%). During storage peroxide value, free fatty acid, moisture content and thiobarbituric acid of the oil were within the maximum limits as recommended by CODEX Alimentarius.

Article is devoted to the results of modeling-a certain mathematical function that describes the behavior of the object of study, abstracting from the internal structure of the real substrate. Materials and Methods: discusses the construction of models of experimental dependencies extruding abnormally viscous fluids, includes the following stages: clarification, depending on the specific tasks optimized parameters (specific energy consumption in the extrusion process, the pressure in predatrice area, complex organoleptic quality score, etc.); the choice of factors determining the variability of the optimized parameters (initial moisture of the product, the frequency of rotation of the screw, the living section of the matrix, etc.); the selection of intervals of change of factors; recruitment plan and the conditions of the experiment; analysis of experiment data and construction of mathematical model of dependencies of optimized parameters on selected factors.Results: when planning an experiment, the conditions for conducting experiments, obtaining reliable and accurate information about the object, with minimal effort, providing information in a convenient form and quantitative accuracy assessment.

Conclusion: the obtained results reveal the influence of individual factors on the operation of extruders and can be used in the design and optimization of their operation. They will have an impact on the development of scientific, scientific, technical and technological directions in the field of creating new food products with programmable properties (including therapeutic and prophylactic action). Made on their basis, experimental design will reveal new technological solutions in the field of creation of new generation technological equipment for various branches of the food industry. The developed recommendations and proposals for the use of the results are already used in the ongoing innovative projects for the creation of extruders, as well as other equipment.

Micronutrient deficiency is a major concern now a days as more than 30 percent of world’s population is suffering from nutritional deficiency. People are getting awareness regarding food biodiversity, therefore they demand value added and nutritionally enriched food products to counter appetite as well as to improve their health. This study was conducted to assess the nutritional potential of Moringa oleifera leaves powder (MOLP) and a product was developed to ensure its efficient utilization in chapatti (Unleavened flat bread). For this purpose proximate composition was analyzed for both moringa oleifera leaves powder and whole wheat flour (WWF). The depicted results for MOLP were as 10.75% moisture, 7.79% ash, 6.49% crude fat, 23.72% crude protein, 12.48% crude fiber. Afterward, raw materials were analyzed for mineral profile, MOLP showed better mineral content as; 1295 mg/100g K, 211.92 mg/100g Mg, 6.32 mg/100g Cu, 7.37 mg/100g Fe, 12.83 mg/100g Na, 6.3 mg/100g Zn and 8.67 mg/100g Mn, as compared to WWF. Then antioxidant activity of both materials was analyzed and again MOLP showed better results as compared to WWF. The recorded values for Total Phenolic Content (TPC), Total Flavonoid Content (TFC) and antioxidant activity of MOLP were as; 88.63 mg GAE/g, 30.86 mg CE/g and 89.27%, respectively. Furthermore composite flour blend was prepared with the addition of 5, 10, 15 and 20% MOLP in WWF and analyzed for pasting properties then chapattis ware developed and analyzed for mineral profile and antioxidant activity as well as sensory attributes. It was observed that chapatti with 20% MOLP contained highest level of minerals as; 286.07 mg/100g K, 147.75 mg/100g Mg, 5.12 mg/100g Cu, 4.09 mg/100g Fe, 12.83 mg/100g Na, 4.78 mg/100g Zn and 5.78 mg/100g Mn. Similarly the treatment with highest proportion of MOLP showed maximum antioxidant activity; TPC, TFC and DPPH depicted results 8.83 mg GAE/g Extract, 3.66 mg CE/ g of extract, 80.52% respectively. The sensory evaluation of chapatti exhibited that treatments which had 5 and 10% of MOLP demonstrated comparatively better results with overall acceptability scores 6.90 and 6.20, respectively, however T2 (10% MOLP) was the best acceptable combination regarding its sensorial attributes. Conclusively the micronutrient profile and antioxidant activity of chapattis gradually enhanced by increasing the level of MOLP.

The physicochemical, functional and sensory properties of acha-tamba based ogi enriched with hydrolyzed soy peptides were investigated. The proximate value moisture content increased with percentage inclusion of acha tamba and peptides additions (10.1-11.5) % Similar trend were observed in protein values (2.15-8.02) %, Ash (3.05-3.34) %, crude, fiber (7.05-10.6) % and carbohydrate content 65.9-69.2) % which had down tail trends on acha ,tamba and peptides percentage inclusions. Water absorption capacity (1.07-1.24) g/ml oil absorption capacity (1.10-1.91) g/ml and swelling index (3.06-3.50) g/ml revealed increased content with material inclusions. The chemical properties of PH (4.27-4.6), Titratable acidity (0.88-0.97) and Total soluble solids were favored with material percentage inclusion. The sensory results revealed that sample Band sample C with moderate percentage inclusion of 10% and 20 % acha, tamba and soypeptides were more acceptable by panelists.

A modern progressive direction in the development of confectionery production is the creation of new resource-saving technologies and the development of flour confectionery products with a reduced energy value based on the use of various types of non-traditional and local raw materials. The application of oilseed cake in the food industry makes it possible to enrich products chemical composition with proteins, lipids, dietary fiber, vitamins and minerals. The use of amaranth oil cake as a dry component allows the biological value increase, as it is characterized by a high content of easily digestible protein (18-20%) containing all essential amino acids in sufficient quantities. Recently, special attention has been paid to the introduction of animal fats to the food industry. Bone fat occupies a special place among them. It is produced from bones, regardless of the type of meat from which they were obtained. The application of bone fat allows to enrich foods with polyunsaturated fatty acids, as well as improve the ?-3 / ?-6 ratio of fatty acids in the diet. Taking into account the traditional technology, as well as the properties of amaranth cake and bone fat, the recipe for "Mayachok" gingerbread was developed to adjust chemical and fatty acid composition. The recipe for custard gingerbread with the addition of 15% amaranth oil cake and 11% bone fat to the flour mass in the dough improves organoleptic and physicochemical indicators; to increase their biological value (by 24.5%); to obtain products with the most balanced amino acid composition (amino acid rate for lysine is 44.5%); to balance the ?-3 / ?-6 ratio of fatty acids; to increase the calcium content in products and to normalize its ratio with magnesium and phosphorus - Ca: Mg: P - 1: 0.65: 1.65. The components added improve the structural and mechanical properties of the choux pastry, such as plasticity, elasticity, absorptivity.
