Each raw material contains a different amount of the necessary sub- stances for the mixture. The mixture should meet the mini- mum utility requirements. It is necessary to determine the amount of each j-th type of raw material, forming a mixture of minimum cost, subject to the requirements for the total consumption of the mixture and its nutritional value. The op- timization problem based on a mathematical model will have the form 2-5 , under restrictions: • total consumption of the mixture: ; • nutritional value of the mixture: ; • ; where: xj is the amount of j-th raw material in the mixture; n is the number of types of raw materials; m is the amount of nutrients; aij is the amount of the i-th nutrient contained in the unit of the j-th type of raw material; b 1 – the minimum amount of the i-th nutrient contained in the unit of the mixture; c j – unit cost of raw material j; q – minimal general view of the mixture. Vitamins have extremely high biological activity and are re- quired by the body in very small quantities (from a few mi- crograms to tens of mg), i.e. are minor components of food (micronutrients). Unlike other essential nutrients (essential amino acids, polyunsaturated fatty acids), vitamins are not a Int J Cur Res Rev | Vol 12 • Issue 19 • October 2020 54 Sultaniyazovich et al.: Nutrition modeling during the prenatal development of the fetus building material or energy source and participate in metabo- lism mainly as biocatalysts and regulators. The human need for vitamins (physiological need) is an objective value that has developed during evolution and does not depend on our knowledge. Based on scientific data on the study of physi- ological needs, the recommended intake rate (RNP) of vita- mins is established (Table 2). It fully covers the need of any person. The need and, accordingly, RNP for pregnant women is approximately 25% higher than for women of childbear- ing age. Download 411.25 Kb. Do'stlaringiz bilan baham: |
