Grape (Vitis vinifera L. var. Albariño) and mulberry (Morus nigra L.) seeds pomace were characterized in terms of tocopherols, organic acids, phenolic compounds bioactive properties. Higher contents tocopherols (28 ± 1 mg/100 g fw) obtained mulberry, whilst grape richer acids (79 4 fw). The analysis hydroethanolic extracts characterised by catechin oligomers (36.0 0.3 mg/g) ellagic acid derivat...

Abstract Background Sixty five percent of procyanidins in grape seeds is polymeric (PPC), and they could not be assimilated directly by human. To enhance procyanidin assimilation, steam explosion treatment (SE) was used to facilitate the preparation oligomeric (OPC) from seeds. Results The results indicate that SE made loose porous, decreased mean degree polymerization (mDP) procyanidins. conte...

Paradox (Juglans hindsii × J. regia), the dominant rootstock used in California, USA walnut production, has many desirable horticultural characteristics, but is highly susceptible to crown gall. Crown gall, caused by the bacterium Agrobacterium tumefaciens, is not consistently controlled with soil fumigation. This observation, in conjunction with observations of galls occurring in above ground ...

The was carried out coincide with July 19, 2020, until September 17, in Sarirejo Hamlet, Pereng Village, Mojogedang District, Karanganyar Regency, an altitude 350 meters above sea level. uses a Completely Randomized Design (CRD) procedure which consists treat...

Maceration techniques which promote the extraction of color pigments and tannin from grapes are often sought in Pinot noir winemaking to optimise stability; alternatively, exogenous grape tannins may be included during fermentation. To examine effect seed-derived use pectolytic enzymes on development wines, conventional must preparations Vitis vinifera L. cv were compared with wines made using ...
