Genes, Vol. 14, Pages 1491: The Diversity in Grapes of Vitis labrusca Grown in Bolu (T & uuml;rkiye) Assessed by Multivariate Approaches
This study evaluated the grape genetic resource belonging to the Vitis labrusca species. The diversity was assessed according to morphometric, antioxidant, physicochemical, and colorimetric characteristics. The diversity was evaluated using a variation index and multivariate analyses. The bunch weight of the vines exhibited a range from 21.05 g to 162.46 g, with a coefficient of variation (CV) of 38.97%. The average bunch weight was 64.74 g. In terms of the berry properties, the highest CV was observed for the berry weight (21.95%). The peel thickness displayed a CV of 36.40%, and an average of 0.23 mm. The CVs for the jui...

Efficacy of pterostilbene suppression on Aspergillus flavus growth, aflatoxin B < sub > 1 < /sub > biosynthesis and potential mechanisms
Int J Food Microbiol. 2023 Jul 10;404:110318. doi: 10.1016/j.ijfoodmicro.2023.110318. Online ahead of print.ABSTRACTAspergillus flavus, a widespread saprotrophic filamentous fungus, could colonize agricultural crops with aflatoxin contamination, which endangers food security and the agricultural economy. A safe, effective and environmentally friendly fungicide is urgently needed. Pterostilbene, a natural phytoalexin originated from Pterocarpus indicus Willd., Vaccinium spp. and Vitis vinifera L., has been reported to possess excellent antimicrobial activity. More importantly, it is quite safe and healthy. In our screening ...

Vitis vinifera L. Bioactive Components Modulate Adipose Tissue Metabolic Markers of Healthy Rats in a Photoperiod ‐Dependent Manner
ConclusionsThese results clearly show that bioactive compounds of grapes can modulate the metabolic markers of white and brown adipose tissues in a photoperiod and depot-dependent manner, partly affecting EE when consumed out of season. (Source: Molecular Nutrition and Food Research)

Molecules, Vol. 28, Pages 5227: Rapid In-Field Volatile Sampling for Detection of Botrytis cinerea Infection in Wine Grapes
In this study, zeolitic imidazolate framework-8 (ZIF-8) crystal was applied as an absorbent material for volatile extraction from B. cinerea infected and healthy grapes in a vineyard, followed by thermal desorption gas chromatography&amp;ndash;mass spectrometry. The performance of ZIF-8 in regard to absorbing and trapping the targeted volatiles was evaluated with a standard solution of compounds and with a whole bunch of grapes enclosed in a glass container to maintain standard sampling conditions. The results from the sampling methods were then correlated to B. cinerea infection in grapes, as measured and determined b...
