Study On Functional Nutritious Protein Powder

According to the protein suppplementary action, the soy protein isolate and Whey Protein Concentrate ( WPC ) was mixed in an optimal proportionment, in order to make sure the contents of essential amino acid were enough for the human demand, and that the mixed protein powder has a good quality, and can be absorbed easily. In order to prevent the Postmenopausal osteoporosis, the soyisoflavone was supplemented, and the DHA and taurine was supplemented in order to enhance the learning ability of children.In this paper, the preventive effects of soyisoflavone-rich nutritious protein powder on Postmenopausal osteoporosis in ovariectomized rats was studied. The results have shown that the soyisoflavone-rich nutritious protein powder can increase femoral BMD ( P<0.01 ). bone calcium and phosphor ( P<0.01 ), and it can decrease the BGP and the activity of TRACP, and also can increase the activity of ALP. So it was provided with a better prevention for Postmenopausal osteoporosis.The effects of DHA and taurine supplemented nutritious protein powder on brain in 3-weeks old mice ( female and male ) was studied in this paper. The Morris water maze task and step down test were used to test the learning ability of mice, and the examination index includes protein and MDA content of brain, SOD and TChE activity. The results indicates: DHA and taurine supplemented nutritious protein powder can decrease the escape latency ( P<0.05 ), and increase the time and distance of swimming in the target quadrant in the Morris water maze task ( P<0.05 ); and it can decrease the number mistake and increase the times of electric shock in the step down test ( P<0.05 ). And protein content of brain and SOD activity increased significantly, but the MDA content and TChE activity did not show a significant change. All of the results show that DHA and taurine supplemented nutritious protein powder can improve the ability of learning and memory of growing mice.
