Abstract:
... BACKGROUND: The ‘clean label’ trend is pushing the food industry to replace synthetic colorants with plant‐based colorants. However, technological efficacy and undesirable side effects restrict the use of plant‐based colorants in industrial applications. This research studied the production of fermented maize dough coloured by apigeninidin‐rich red sorghum biocolorant, as practised for centuries i ...

Abstract:
... BACKGROUND: Climatic and dietary shifts predispose ruminal microbes to hyperthermal and hyperosmotic stress, leading to poor fermentation and subsequently adverse effects on ruminant productivity. Betaine may function as substrate, osmolyte, antioxidant, and methyl donor for microbes. However, its effect depends on the extent of microbial catabolism. This study revealed the ruminal disappearance k ...

volatile compounds; sensory evaluation; free radicals; photosensitivity disorders; plant fats and oils; triacylglycerols; antioxidants; oxidation; gas chromatography; aldehydes
Abstract:
... In a major pathway of the autoxidation of methyl linolenate, peroxyl radicals of the internal hydroperoxides undergo rapid 1,3-cyclisation to form hydroperoxyepidioxides. Because linolenate hydroperoxides are relatively unstable, free radical antioxidants are much less effective in linolenate oils than in linoleate oils. Tocopherols and carotenoids effectively, inhibit photosensitised oxidation of ...

The first assay was conducted in 1999 and 2000 in Beaumont, TX and included five light-brown, two purple and 10 red pericarp coloured cultivars. 'Bran colour' was highly statistically significant for both bran ph ...
