12th IFDC 2017 Special Issue – High protein sports supplements: protein quality and label compliance
This study will provide a better understanding of the current protein powder supplement industry to inform food control agencies for their future policy and program development. Actual protein contents analyzed were statistically different (p < 0.05) from the respective labels in 68.6% of the 70 products. Five products (7%) had protein content values differing by more than 25% of that stated on the product label. In addition, amino acid content (indicative of protein quality) was assessed on a subsample of 15 products. According to current draft label regulations of foods, the protein quality of 40% of these produ...

Individualized Human Milk Fortification to Improve the Growth of Hospitalized Preterm Infants.
CONCLUSION: About two-thirds of preterm infants needed to adjust the HM fortification to a higher level. The WGV of infants in the IF group was better than that of the standard group in the third week of this study.

Characterisation of water-soluble protein powder and optimisation of process parameters for the removal of sulphonamides from wastewater.
Abstract
A valuable method for the efficient removal of sulphonamides from wastewater using protein powder extracted from the seeds of Moringa stenopetala is presented in this study. The surface morphology, crystallinity and functional groups of protein powder were characterised by SEM, XRD, FTIR and Raman spectrometry. Parameters that affect the removal of sulphonamides, such as concentration, the adsorbent dosage and pH, were optimised. The method was applied to a real wastewater sample collected from the Daspoort Wastewater Treatment Plant located in Pretoria, South Africa. The percentage removal under ...

The Effect of Soy Isoflavones on Steroid Metabolism
Conclusion: In Vivo clinical data suggested inhibition of CYP17A1 17,20 lyase within the adrenal in men and within the ovary and adrenal in females. This was confirmed in vitro with inhibition of the lyase activity by both genistein and daidzein. In addition, 3βHSD2 was inhibited perhaps accounting for decreased A4 levels observed in females. The decreased DHEAS and A4 levels together with the inhibition of the 17,20 lyase activity of CYP17A1, may impact production of androgens in clinical conditions associated with androgen excess.

Influence of casein on the formation of whey protein microparticles obtained by dry heating at an alkaline pH
In conclusion, our study shows that the process of DH at pH 9.5 could be applied to all milk proteins to obtain PMs with functional properties that could be used in the food industry.Graphical abstract (Source: Food Research International)
