Study On The Pregnant Woman Formula Food And Its Functional Effect

During the gestation period, women need more nutrient, though Chinese pregnant women usually are lack of the necessary intakes, and the health between mother and baby is threatened by the phenomenon. According the Chinese medicine, the pregnant woman should be pay more attention to intake the variety nutrient. They should choose some traditional Chinese tonics to supply the intakes, improve the function of physiology, adjust the metabolism. In this topic, choosing Fructus Lycii, Chinese Date, Black rice and Rhizoma Dioscoreae as the raw material, after the pre-processing mix with milk the product is the formula milk. At the same time, according the DRIs reference and the data to show deficiency. Comparing the results on nutrient of basic formula milk, supplying the nutrient by man-made method. Using the final product into the animal experiment to inspect the function.Chinese Date is extracted two times. Taking the orthogonal experiment in the first time get the optimum condition: water (6 times ), 70C, 3hr, dry solid extraction rate (75.1%), and then add water (4times ), 70C, 2hr, total dry solid extraction rate (95.6%).Fructus Lycii is extracted by pectase liquefaction, taking the orthogonal experiment. Get the optimum condition for the dry solid: water (lOtimes), 40'C, [E/S]= 0.04%, 3hr, dry solid extraction rate 84.1%; get the optimum condition for the total sugar: water (lOtimes), 40*C, [E/SJ=0.05%, 1.5hr, extraction rate of the total sugar: 119.9%. According the optimum experiment, get dry solid of Fructus Lycii: 7.1%, Fructus Lycii Polysaccharide (LBP) 1.1%.By extrusion and gelatinization processing, the Black rice dissolved water to get sediment rate, extrusion: 16.45%, gelatinization: 43.30%. In the same condition hydrolysis sediment use the papain and a -amylase, get the hydrolysate, extrusion: 9.10%; gelatinization: 34.64%. Comparing the results, the fact show extrusion can effectively hydrolysis and improve the product stable. Measure TCA-NSI and reducing sugar of hydrolysate, extrusion: 84.5% and 3.99%, respectively; gelatinization: 76.9% and 1.05% respectively. As the results extrusion is more helpful to absorb the protein and starch. Considering the benefit to sense and digestibility of the product, extrusion is used in this experiment Single factor experiment is adopted to get the optimum condition: the water in raw material is 12%, grain size is 20 orifice.Pregnant woman intakes is marked by reference and sense of product, designed by four factors three level orthogonal experiment, get optimum formula is: Chinese Date 5.5g, Fructus Lycii 5g, Rhizoma Dioscoreae 3.26g, Black rice 4.4g (to maintain the dry solid, use the raw material: Chinese Date 9g, Fructus Lycii 6g, Rhizoma Dioscoreae 20g, Black rice 5g). Use skim milk powder adjust dry solid to product the basic formula milk (dry solid 12%). Because the liquid in the skim milk powder is 8.2%, the addition of skim milk powder is 32.5g, the rest part is replenished by water.The basic formula milk maintain the same time at different pressure, get the sedimentrate after centrifugalization the optimum condition is ISMpa. The basic formula milk is heated respectively 15, 20, 25, 30, 35, 40min under 60, 70, 80, 90, 100C to inspect the heating stability. The result show formula milk heating stability is more effectively by the higher temperature and the longer time.According the collected files suggest the pregnant women intakes from different local: although the energy intakes can satisfy the need of women, the subdepartment of three nutrient are unreasonable, the main reason is the lower protein, especially perfect protein; the intakes of mineral and vitamin are distinguished by area and person. The rules designed of entirely formula: the number supplied of every kind of nutrient in different step = the reference in every period - the real intakes in every period -content in the basic formula. According to die result of in entirely formula design made three multiple nutrient during the early, middle, late pregnancy. Choose the singl...
