In the production of wine distillates, factors influencing their composition, respectively quality, can be divided into following directions: composition grapes (as raw material), technology for its processing and alcoholic fermentation to obtain material, as well method distillation material derive a distillate. Each these is important quality distillate significantly affects concentration che...

Aroma is an important part of quality in table grape, but the key aroma compounds and the aroma series of table grapes remains unknown. In this paper, we identified 67 aroma compounds in 20 table grape cultivars; 20 in pulp and 23 in skin were active compounds. C6 compounds were the basic background volatiles, but the aroma contents of pulp juice and skin depended mainly on the levels of esters...

The aim of this study was to evaluate the effects silver nitrate (AgNO3) and nano-silver (Ag-NPs) on physiological biochemical characteristics, quality grape bunches during a cold storage period. For investigations, two varieties grapes were used, Shine Muscat Kyoho, with different concentrations AgNO3 Ag-NPs post-harvest dipping. data indicated that enhanced fruits’ longevity quality. Dependin...

During recent years a large annual surplus of grapes has been produced in the United States, and the development of new grape products to take care of this increasing supply is at present an important phase of the grape industry. Because of the general interest in a fruit so abundantly grown, it seemed desirable to study the nutritive value of grapes and grape juices more extensively than had p...

Traditionally, when making white wines, the musts are subjected to clarification and settling, even those from harvests in perfect phytosanitary condition. The increasingly perfected technical technological procedures, involved operation of clarifying deburring musts, lead total removal undesirable impurities, but also small fragments skins core, only carriers varietal aromas specific each vari...

2-Methoxy-3-isobutylpyrazine (MIBP) contributes a bell pepper aroma to many grape cultivars and has a reported aroma threshold of ∼2 ng L(-1) in water. The purpose of this study was twofold: (1) develop a procedure using headspace solid phase micro-extraction combined with GC-MS in the selected ion monitoring mode (HS-SPME-GC-MS-SIM) for analysis of MIBP in grape berries, and (2) determine the ...

Grapes are rich in phenolic compounds, being important for human health with anti-inflammatory, antiatherosclerotic, antimutagenic, anticarcinogenic, antibacterial, antiviral, and antimicrobial activity. The winemaking of the grapes generates significant amounts waste. These wastes contain bioactive compounds their biomass that can be used as a source food improvement or nutrition supplementati...

The soluble solids content (SSC) is one of the important evaluation indicators for internal quality fresh grapes. However, current non-destructive detection method based on hyperspectral imaging (HSI) relies manual operation and relatively cumbersome, making it difficult to achieve automatic in batches. Therefore, this study, we aimed conduct research an improved SSC bunch-harvested This study ...

grown in California because of its high productivity, wide soil adaptability, seedless fruit, and versatility for use in different grape and raisin products. About 95 percent of California raisins are currently produced from ‘Thompson Seedless’ grapes, followed by ‘Fiesta’ (3 percent) and ‘Zante Currant’ (1.5 percent). The remainder are produced from ‘DOVine,’ ‘Muscat of Alexandria,’ “Sultana” ...
