Abstract In order to improve the utilization value of by-product mulberry, remaining residue mulberry wine was used as raw materials extract anthocyanins from by enzymatic method, and response surface method optimize extraction process. Firstly, single factor experiment carried out controlling four factors: liquid-solid ratio, time, temperature pH value. Then, Box-Behnken design a three-factor, three-level experiment. Finally, The results showed that optimal process pectinase ratio 1:20,...

In monsoonal climates, grape anthocyanin and proanthocyanidin (PA) accumulations are unsatisfactory for producing optimal wine. Agronomical practices often considered to be effective means regulating fruit components. However, there is a lack of quantitative information on the effects deficit irrigation (DI), basal leaf removal (LR) or their combination (DILR) characteristics PA compositions implications resulting wine quality. this study, dynamics accumulation were investigated in DI, LR...

Abstract Using local mulberry products in Chuxiong as raw material, skin residue was obtained after brewing wine, and the anthocyanin extraction process optimized by ultrasonic assisted water method. Firstly, single factor experiment used to study effects of four different factors, namely, ratio feed liquid, temperature, time power, on from mulberries. On basis test, optimal design response surface analyzed. According analysis results practical verification, ultrasound-assisted conditions...

Spine grapes are widely cultivated in southern China because of their strong adaptability to hot and humid climates. As a wild species native China, spine grape (Vitis davidii Foëx) was studied as resource proanthocyanidins (PAs). PA composition, biosynthesis, histochemistry different tissues (skins, seeds, stems) during berry development were analyzed this study.

The turbidity and precipitation affect seriously sensory quality of chaenomeles juice wine. In order to reduce the harmful effects turbid on fermentation ensure fruit wine, pectinase was used clarify in this experiment. gradient dosage designed into 20, 25, 30, 35, 40 45 mg/L. optimum selected for clarifying juice. chemical clarification method (bentonite chitosan) employed stabilize raw improve its appearance risk diseases storage process, by designing bentonite dosage, 0.8, 0.9, 1.0, 1.1,...

Abstract Northeast China is one of the major wine-making grape bases in China. It great significance to study influence climate change on planting regionalization northeast for industrial layout and variety selection. According 168 weather stations Daily meteorological data, calculate frost-free period, growing season dry degree, active accumulated temperature April September, average annual extreme low other indicators, 45 years from 1967 2011 grapes zoning index trend, using GIS analysis...

In order to study effect of oak sawdust on the quality Kyoho wine immersed by fermented Cabernet Sauvignon residual, aged without (KWO), including KWO1 and KWO2 according orders was taken as control compare (KO), KO1 KO2 sawdust. During 15 days aging, physical chemical indicators, such chroma, tonality, total phenol in were determined simultaneously using a spectrophotometer, tannin content KMnO 4 titration, once every 3 days. The results showed that chromaticities 3.21, 3.02, 4.46, 3.71 for...

The Hengduan Mountain region of China is one the world's highest altitude and lowest latitude wine grape cultivation areas. This study screened existing regional indexes; active accumulated temperature (AAT) for grapes in growing season was chosen as heat index, dryness index (DI) water climatic regionalization. An analysis 90-meter resolution digital elevation model (DEM) data corresponding slope degree direction range 97°E-103°E, 27°N-33°N, well daily meteorological over 30 years...

Abstract Effects of different acid-reducing methods on the deacidification effect papaya fruit juice and wine, thought as raw materials, were studied.
