Seventy-two Yorkshire boar pigs were used to study growth rate and feed efficiency in pigs weaned at 3 weeks of age and fed either casein or soy-protein as a source of supplemental protein in corn based diets. Treatments consisted of a corn-casein diet, a corn-isolated soy protein diet, a corn-ethanol extracted soy protein diet and a corn soybean meal diet. Feed intake was not affected by sourc...

To the Editors: Goodin et al. (1) reported a 19% decrease in mean serum testosterone levels among 12 men over a 4-week period in response to the daily consumption of 56 g isolated soy protein. These data are inconsistent with the results of a meta-analysis recently completed by the authors of this letter. This inconsistency, as judged by Fig. 1 in the paper by Goodin et al. (1), may stem largel...

Changes of structure and thermal stability of soy protein isolate after pulsed electric field treatment were analyzed by Fourier transform infrared spectroscopy and differential scanning calorimetry (DSC). When the applied pulsed electric field (PEF) treatment intensity was over 35 kV/cm, the amino acid side chain, anti-parallel b-sheets, b-turn as well as b-sheets in soy protein isolate (SPI) ...

Soybeans (Glycine max) are an abundant source of proteins that have been recognized for their high nutritional value and bioactive properties. Soybeans are legumes, and possess high protein content (approximately 40%) as compared to most other legumes (Aguirre et al., 2008; Yimit et al., 2012). The health benefits of soybeans are attributed to the presence of bioactive compounds, and in particu...

Athletes as well as elderly or hospitalized patients use dietary protein supplementation to maintain or grow skeletal muscle. It is recognized that high quality protein is needed for muscle accretion, and can be obtained from both animal and plant-based sources. There is interest to understand whether these sources differ in their ability to maintain or stimulate muscle growth and function. In ...

CONTEXT Isolated soy protein reduces plasma concentrations of total and low-density lipoprotein (LDL) cholesterol. OBJECTIVE To identify the agent(s) responsible for the cholesterol-lowering effect of soy in mildly hypercholesterolemic volunteers: isoflavones isolated together with soy protein or soy protein itself. DESIGN Double-blind randomized parallel trial. SETTING Single-center stud...

The elderly population in developed countries has increased rapidly recent years; the may be at greater risk of protein deficiency due to dietary, socio-economic, dental, and physical restrictions. Therefore, address issue people, present study aimed enhance content high-gluten flour noodles, an Asian staple food, by supplementing them with soybean isolate (SPI) powder. effect SPI addition (5–2...

This manuscript focuses on the production of polymeric matrices enriched in minerals and antioxidant compounds. The biopolymers employed are obtained from different by-products agro-food industry (porcine plasma protein, pea protein concentrate soy isolate), which helps to revalorize them. Two manufacturing techniques produce these matrices: 3D-printing injection molding. Bioactivity was enhanc...

Soy isoflavones exhibit a number of biological effects, suggesting that they may have a role in cancer prevention. Our objectives are to determine whether components of soy products or purified soy isoflavones can inhibit the progression of bladder cancer. We compared the in vitro effects of pure soy isoflavones and soy phytochemical concentrate on growth curves, cell cycle progression, and apo...
