This study was carried outto investigate the effect of ultrasound-assisted extraction (UAE) on polyphenols from olive pomace with methanol (80%) as an extracting medium and studythe effects of addingthe extract to refined sunflower oilduring accelerated oxidationconditions. Ahigh amount of polyphenols was extracted from the olive pomace with a solvent-to-solid ratio of 40 at 50% of the maximum ...

Abstract This study aims to assess kinetic modelling of the solid–liquid extraction process total polyphenolic compounds (TPC) from apple pomace (AP). In this regard, we investigated effects temperature and solvent (i.e. water, ethanol, acetone) on TPC over various periods. The highest yield 11.1 ± 0.49 mg gallic acid equivalent (GAE)/g db (dry basis) was achieved with a mixture 65% acetone–35%...

Pectin extracted from the apple pomace was evaluated for the in vitro inhibition of pancreatic lipase (steapsin). Pectin was extracted from two different varieties of apples, i.e., Malus pumila and Spondias dulcis using two extractants, i.e., hydrochloric acid and citric acid (CA), separately at pH 2.5.

This study was conducted to investigate the metabolizable Nutrient values of Tomato Pomace (TP) in Nile tilapia (Oreochromis niloticus). Ninety days (three month) old fish were divided into 2 groups, each group consists from 12 aquariums, and each aquarium contains 12 Nile tilapia fingerlings whereas the excreta could be collected. Fish in each group were randomly fed basal diet or basal diet m...

The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg(-1) body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg(-1) body weigh...

Apple pomace extract (APE) in aerobic variable fed batch culture under standardized fermentation parameters was evaluated for the production of baker’s yeast. The substrate was fed at a flow rate of 0.39 dm h to regulate fermentable sugar concentration between 1-2 % in bioreactor. An average specific growth rate of 0.24 h and cellular yield coefficient of 0.48 g/g sugar was obtained during bake...

Pectinase (Pectin methyl esterase) produced by Aspergillus niger in solid state fermentation of apple pomace using the optimized conditions was partially purified by (NH4)2SO4 fractionation (20-80% concentration). The purified enzyme was found to be stable up to 60 days. It remained heat stable up to 50oC but completely inactivated at 90oC. The partially purified enzyme showed highest activity ...

W.F. FETT, C. WIJEY, R.A. MOREAU AND S.F. OSMAN. 1999. Ten strains belonging to various Thermomonospora species were tested for their ability to hydrolyse the insoluble plant polyester cutin. One strain, the thermophile T. fusca ATCC 27730, was found to produce a highly inducible cutinase when grown in broth medium containing purified apple cv. Golden Delicious cutin. Apple pomace, tomato peel,...

Apple pomace which is the main waste of fruit juice industry was utilized to extract pectins in an environmentally friendly way, which was then compared with chemically-extracted pectins. The water-based extraction with combined physical and enzymatic treatments produced pectins with 693.2 mg g(-1) galacturonic acid and 4.6% yield, which were less than those of chemically-extracted pectins. Che...
