Microwave (MW) vacuum dehydration using temperature to control the level of MW power demonstrated potential in improving the performance of the process. Product surface temperature measured by an infrared temperature sensor was used to control MW power at any level between 0 and 3 kW. Multiple linear regression analysis indicated an r2 = 0.942 for prediction of final moisture content and r2 = 0...

In accordance with data provided from Mathematics Modeling Competition for National University students in 2012, it can be found whether grapes are high-quality or not as well as the direct relationship between the grape and wine quality by means of SPSS and other statistical softwares, through multivariate statistical analysis and data analysis, and by verifying the credibility what comments m...

Samples of grapes are originating from different Italian areas and purchased from local and Romanian markets.During the fermentation, yeasts convert most of the sugar in the grape juice into ethanol. Grapes may be potent against tumors because of their high concentration of tannin. Selenium enriched yeasts may be a safe source as a diet supplement. Saccharomyces cerevisiae is normally present o...

Recently published research has identified that the use of a ‘wine-like’ 15% ethanol extraction method when analysing grape tannins provides a strong indication of tannin concentration that is likely to result when those grapes are made into wine. The AWRI has developed a rapid and practical method for determining extractable tannins in red grapes, which involves gentle crushing of grapes by ha...

Anthocyanins, synthesized via the flavonoid pathway, are a class of crucial phenolic compounds which are fundamentally responsible for the red color of grapes and wines. As the most important natural colorants in grapes and their products, anthocyanins are also widely studied for their numerous beneficial effects on human health. In recent years, the biosynthetic pathway of anthocyanins in grap...

The present study compared the effects of consuming red versus white whole grapes on oxidative and lipidemic indices in people with hypercholesterolemia. Sixty nine patients were randomized into three groups. The two treatment groups consumed 500 g of either Condori red grapes or Shahroodi white grapes daily for 8 weeks, and the third group served as a control. Plasma glucose, triacylglycerol (...

The paper briefly outlines the business modeling language GRAPES-BM and the CASE tool GRADE-BM based on it. The business modeling language GRAPES-BM is a semiformal graphic language for modeling and simulation of complicated business systems (production processes, offices, information systems). GRAPES-BM relies on such basic concepts as task, event, performer, triggering condition etc. and cont...

Table grapes (Vitis vinifera cv. Cardinal) are highly perishable and their quality deteriorates during postharvest storage at low temperature mainly because of sensitivity to fungal decay and senescence of rachis. The application of a 3-day CO2 treatment (20 kPa CO2 + 20 kPa O2 + 60 kPa N2) at 0°C reduced total decay and retained fruit quality in early and late-harvested table grapes during pos...

Grape harvest date is determined according to the technological and phenolic maturities. These parameters were calculated for different red grape (Vitis vinifera L.) varieties (Cabernet Sauvignon, Merlot, Syrah, Cabernet Franc) over four years (2008, 2009, 2010, and 2011) (642 samples). Titratable acidity and sugar content of the grapes were used to determine the technological maturity, whereas...

This study investigated the efficacy of ultraviolet-C (254 nm) and induced stilbenes to inhibit Aspergillus carbonarius and Aspergillus tubingensis and control ochratoxin A production in grapes. In addition, the stilbene synthesis as a response to UV-C treatment and to infection of ochratoxigenic Aspergillus was compared. The initial microbial inactivation by a previously optimized UV-C illumin...
