This study aimed to evaluate the effects of extraction time, extraction temperature and water to pomace ratio on the total phenolic content and antioxidant activity of apple pomace aqueous extracts. Pomace was extracted using water (20-90°C) for 5-60 min. The extracts were evaluated for their total phenolic content (Folin Ciocalteu assay) and antioxidant activity (DPPH, FRAP and ABTS assays). A...

Environmental problems have encouraged investigation of renewable energies. The organic waste treating through fast pyrolysis seems to be a highly promising option for decreasing pollutants. Olive pomace, major source in countries with high production olive oil (mainly Spain, Italy, and Greece), is clear target valorisation. Dried pomace together the ashes obtained during drying process was ble...

PURPOSE The objective of this study was to establish the composition of polyphenolic preparations obtained from industrial strawberry pomace with two methods of extraction: the water and the water-alcoholic one and then to analyse their effects in the gastrointestinal tract depending on the composition of dietary fibre-cellulose or fructooligosaccharides (FOS). METHODS Freeze-dried water extr...

Grape pomace contains high levels of valuable antioxidants such as anthocyanins and phenolic compounds that help prevent chronic diseases such as cardiovascular problems and cancers. In this study, Concord grape pomace was soaked in acidic solutions at different time intervals and pHs in a water bath at 80 o C. Five kinds of anthocyanins were released and identified in the pomace after acid hyd...

this experiment was carried out to study effect of supplementary multi enzyme (0, 4 gr per 100 kg of diet) to corn-soybean meal based diets with different levels of tomato pomace (tp, 0, 2, 4, 6 and 8 %, respectively) on chick performance and carcass traits. four hundred and eighty 480 day-old chicks (ross-308) were employed [four replicates (n=20)] in a completely randomized experimental desig...

Sustainable food production is one of the main goals of the modern world. Nowadays, there is a growing interest in the exploitation of the by-products generated from agriculture and food production as raw materials for obtaining high-value products, which can be used for various purposes in the pharmaceutical, cosmetics and food industries. During the winemaking process, about 20 % of the grape...

Samples of fresh apple pomace were collected from 14 loads of apple pomace as delivered from the processing plant in October 1968 and from stored apple pomace that had been obtained in October 1967 and fed during a feeding trial from mid-November 1967 through April 1968. All samples were analyzed for dicofol (kelthane), tetradifon (tedion), DDT, DDD and DDE. For the pesticide residues in fresh ...

UNLABELLED Grape juice processing by-products, grape seed and pomace are a rich source of procyanidins, compounds that may afford protection against chronic disease. This study was undertaken to identify optimal extrusion conditions to enhance the contents of monomers and dimers at the expense of large molecular weight procyanidin oligomers and polymers in grape seed and pomace. Extrusion varia...
