Antioxidant activities and phenolic compounds of raw and cooked Brazilian pinhão (Araucaria angustifolia) seeds

  In this study, the antioxidant properties and the polyphenolic contents of raw and cooked pinhão seeds were evaluated. Four methods were used to evaluate the antioxidant activity: 1,1-diphenyl-2-picrylhydrazyl free radical scavenging (DPPH), 2,2’-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid scavenging (ABTS), ferrous ions chelating activity and lipid peroxidation inhibition (LPO). The...

A comparative microbiological quality assessment of rural and urban milk samples

  The present study deals with the comparative microbiological quality assessment of raw cow milk samples procured from rural and urban farms of Sambalpur City, Odisha, India. The bacterial load of both the rural and urban milk samples in terms of total viable count was observed to be much higher than the acceptable limits. The average total viable count of urban sample was observed to be 8.756 ± 0.803...
