Postharvest softening of grape berries is one of the main problems affecting grape quality during export. Cell wall disassembly, especially of pectin polysaccharides, has been commonly related to fruit softening, but its influence has been poorly studied in grapes during postharvest life. In order to better understand this process, the Thompson seedless (TS) variety, which has significantly dec...

The knowledge generated by this stream has increased the wine industry’s capacity for meeting wine specification and consumer expectations and improving profitability. In particular, this stream was undertaken to provide the Australian wine industry with an improved understanding of structures, measurement, formation and function of phenolic compounds in red and white grapes and wines. Compound...

In this paper, we report measurements of wine viscosity, correlated to polarized laser speckle results. Experiments were performed on white wine samples produced with a single grape variety. Effects of the wine making cellar, the grape variety, and the vintage on wine Brix degree, alcohol content, viscosity, and speckle parameters are considered. We show that speckle parameters, namely, spatial...

Polyphenols are a large and complex group of compounds responsible for the characteristics, quality, and color of grape and wine, especially for red ones. The polyphenolic composition has been extensively studied and a large family of structures have been identied in grapes and wine (Ribereau-Gayon 1965; Somers 1971; Nagel and Wulf 1979; Slinkard and Singleton 1984; Bourzeix et al. 1986; Cheyn...

Although the biological function of fruiting is the production and dissemination of seeds, humans have developed seedless fruits in a number of plant species to facilitate consumption. Here we describe a unique spontaneous seedless mutant (Thai seedless; Ts) of Annona squamosa (sugar apple), a member of the early-divergent magnoliid angiosperm clade. Ovules (seed precursors) of the mutant lack ...

Chitosan is a natural biopolymer that must be dissolved in an acid solution to activate its antimicrobial and eliciting properties. Among 15 acids tested, chitosan dissolved in 1% solutions of acetic, L-ascorbic, formic, L-glutamic, hydrochloric, lactic, maleic, malic, phosphorous, and succinic acid. To control gray mold, table grape berries were immersed for 10 s in these chitosan solutions th...

The aim of the research was to study and isolate promising seedless grape varieties with a complex economically valuable traits adapted arid conditions Northwestern Caspian Sea. objectives included: studying features annual biological cycle grapes, determining leaf area studied varieties, assessing growth strength degree ripening shoots, dynamics shoots. studies were conducted in 2020...2021 vi...

-_ wines, both-white and red, are an excellent source of salicylic acid and its metabolites, 2,3-dihydroxybenzoic acid (DHB), and 2,5-DHB, both of which have proven vasodilator and anti-inflammatory activities, in addition to other healthrelated functions. Many plants, in additiyn to grapes, produce salicylic acid. It is produced in plants as a constitutive and as an inducible defence yhemical....
