Background: Increased popularity of vegetarianism, lactose intolerance, and the high cholesterol content in dairy products, are all factors that have recently increased the demand for nondairy probiotic products. The objective of this study is to evaluate the effect of refrigeration on the viability of p...
Antecedentes: Los arándanos y productos de arándano tienen alto valor nutricional, especialmente por su alto contenido de antocianinas. Estas son potentes antioxidantes y poseen alta capacidad de secuestrar radicales libres. Así, los arándanos y productos de arándanos han resultado atractivos para l...
The fruits and vegetables intake has been associated to the reduction of chronic non-communicable disease incidence, such as cancer, metabolic syndrome and cardiovascular diseases. The biological activities attribute to them has been related mainly to the phenolic compounds, such as flavonoids and ellagi...
Background Several MYB genes belonging to R2R3 MYB transcription factors have been used in several plant species to enhance anthocyanin production, and have shown various expression or regulation patterns. This study focused on the effect of ectopic expression of an RsMYB1 isolated from radish (Raphanus ...
Background Black glutinous rice contains remarkable levels of anthocyanins, which possess anti-oxidative properties and thus have health benefits. The accumulation of anthocyanins in grains of thirty black glutinous rice varieties was measured, and the results revealed that the accumulated anthocyanin co...
ABSTRACT The fruits of Sideroxylon obtusifolium T.D. Penn. are small berries which have dark purple skin color at maturity due the anthocyanins presence. Therefore, the aim of this research was to evaluate the antioxidant activity of anthocyanins from mature fruits which were obtained at a semi-arid regi...
