Impact of GRAS compounds applied by ultrasonic nebulization on decay control and quality parameters in Persian lime.

The application of generally recognized as safe (GRAS) substances for postharvest fungal control of fruit is an alternative to the conventional use of synthetic fungicides. In this study, two GRAS compounds were applied by ultrasonic nebulization (USN) to lime fruit for the control of Penicillium italicum, the cause of blue mold. Lime fruits were treated with sodium bicarbonate (1, 2, 3% w/v), acetic acid (0.

Effect of thermosonication on bioactive compounds, enzymatic and microbiological inactivation in nectar with strawberry by-products.

The aim of this study was to evaluate whether the addition of strawberry by-products (pulp and achene) and thermosonication offers a nectar with a potential contribution of health and safety benefits. Strawberry nectar with 0, 10 and 20% of strawberry by-products (SB) was subjected to thermosonication (24 kHz) at 70 and 80% for 8 min at 50 °C. Total soluble solids, pH, polyphenol oxidase (PO) and pectin methylesterase (PME) activities, total soluble phenols (TSP), ascorbic acid (AA), anthocyanins and antioxidant capacity (AOX) were evaluated.

Gut metabolites produced during colonic fermentation of the indigestible fraction of a maize-based traditional Mexican fermented beverage, .

, is a Mexican fermented beverage prepared by germination-fermentation or nixtamalization-fermentation (artisanal and commercial mode respectively) of maize. The aim of this study was to evaluate the gut metabolites, volatile, and phenolic compounds (PC) produced by the indigestible fraction (IF) of during an colonic fermentation. Twenty-six PC in the IF were identified; the hydroxycinnamic acids (30-40 %) were the most abundant.

Evaluation of as indicator of the efficacy of high hydrostatic pressure and ultra-high pressure homogenization treatments for pasteurization-like purposes in milk.

The objectives of this study were: to assess the efficiency of high hydrostatic pressure or ultra-high pressure homogenization against Mycobacterium smegmatis in milk and to discuss whether M. smegmatis can be considered a suitable surrogate for other Mycobacterium spp. in high pressure inactivation trials using milk.
