CHARACTERIZATION AND DETECTION OF BEEF FAT ADULTERATION IN DAIRY MILK FAT USING RHEOLOGICAL BEHAVIOR

Adulteration investigation using rheological characteristics of DMF (Dairy milk fat) with melted beef fat at various temperatures been evaluated. The change in properties of steady shear and dynamic shear were measured range of 0.01 to 100% by varying strain of 0.1-100 radian per seconds respectively. Generally, DMF resembles the non-Newtonian fluid with flow behavior index (n) for shear thinning fluid of 0.224 to 0.911. The rate of shear ranged 0 to 100/s, dynamic viscosity values decreased DMF, 10%, 20%,30% and 100% adulterated beef fat from 39 to 0.309, 0.591 to 0.103, 0.331 to 0.251, and 0.115 to 0.0858 and -22.1 to -0.65 Pa.s at 36°C, respectively. Herschel–Buckley model optimized to detect the concentration of adulteration with the shear and stress values at R2 ≤ 0.995. The whole value of dynamic viscosity (η*) is more than value of steady viscosity (η) at the pure DMF and concentration of 10% adulteration

Phenolics, tannins, flavonoids and anthocyanins contents influenced antioxidant and anticancer activities of Rubus fruits from Western Ghats, India

Rubus fruits are rich in nutrition with a wide range of phytochemical and consumed by humans, but many of its wild varieties are not commercially useful. Phytochemical exploration of these wild fruits could improve the commercial usage of these Rubus species.This study focuses to analyze the phytochemical, antioxidant and cytotoxicity of three wild Rubus ellipticus, R. niveus and R. fairholmianus fruits comparatively, which has not revealed. The in vitro antioxidant studies indicated the ethyl acetate and methanol extracts of studied Rubus species competent in scavenging different stable and generated radical. The correlation and regression analysis also statistically supported the contents in the extracts could act against various radicals. Correlation between phytochemical constituent and radical scavenging activity found to be highly positive. The results acquired from this investigation revealed that they are equally competent and could be recommended as dietary supplements or as nutraceuticals.
