1. Optimization of extraction time and temperature for natural antioxidants of öküzgözü grape pomace using various solvent ratios
Abstract Grape pomace, a press residue of winemaking process, has great usage potential in many fields because of its phenolic components such as anthocyanins, antioxidants and dietary fiber. In this study, it was aimed to determine most suitable parameters for production of food colorant from grape pomace (variety of öküzgözü) under different extraction

2. Production of functional products using grape processing residuals
Abstract The viticulture – winemaking of Azerbaijan has a rich history and traditions. Grapes have been cultivated and wine made in these places since the ancient times. In the 1980s, the field was in a boom period and provided economic benefits at a level comparable to the country's oil industry revenues. Although the area is currently experiencing a rece

3. Hypolipidemic and antioxidant effects of grape processing by-products in high-fat/cholesterol diet-induced hyperlipidemic hamsters
Abstract Investigations have shown the presence of bioactive substances in agricultural by-products. As some of these compounds present hypolipidemic and antioxidant activities, they could be considered economical alternatives to be used as supplements. This study investigates the hypolipidemic and antioxidant properties of grape processing by-products, feed

4. Optimization of the extraction of phenolic compounds from olive pomace using response surface methodology
ABSTRACT Extraction of olive oil gives rise to large quantities of pomace and liquid effluents, since on average only 21% of the weight of the olive corresponds to oil, the remaining 79% consists of water, bark, pulp and stone. With the intention to make available new forms of use of this residue, this research was proposed, with aimed to optimize the extrac

5. Optimization of beef patties produced with vegetable oils: a mixture design approach and sensory evaluation
Abstract The exaggerated consumption of fast food and ready to eat products is a common practice which results in an unbalanced intake of saturated fats. In order to improve the fat composition of beef patties, mixture design was used to optimize the inclusion of pomace olive oil (POO) and canola oil (CO). Cooking yield, moisture retention, diameter reductio

7. PRODUCTION OF FATTY ACID METHYL ESTERS FROM AN OLIVE OIL INDUSTRY WASTE
ABSTRACT This work studies the synthesis of fatty acid methyl esters (FAME) using crude olive pomace oil as raw material and zinc stearate as catalyst. Pomace oil is a non-edible by-product of olive oil production. The oil was characterized. In order to reduce the plant pigment content in the oil, the liquid was contacted with a modified clay. An experimenta

8. Osseous malformation in calves and its relationship with ingestion of apple pomace in pregnant cows
RESUMO: Descrevem-se 3 surtos de malformações ósseas em bezerros, nascidos de vacas prenhes alimentadas com bagaço de maçã. Estudos foram realizados a partir de levantamento de históricos em propriedades onde bagaço de maçã foi utilizado na alimentação de bovinos. Os surtos ocorreram nos municípios de Lages em Santa Catarina, de 2007 a 2012, e I

9. Blueberry pomace, valorization of an industry by-product source of fibre with antioxidant capacity
Abstract The industrial by-product of blueberry juice, a source of fibre with antioxidant capacity was used to develop cookies. Once dried and ground the blueberries by-product, its composition and functional properties were analyzed and used to develop fibre enriched cookies. A central composite design was used to optimize the cookie formulation maximizing

10. Alternative use of oily fractions of olive oil
Abstract Oily fractions of olive oil not suitable for human consumption used were: lamp oil (AL), olive pomace oil (OO) and clear oil lees (CB). Polyols were obtained by modifications of epoxidation with subsequent hydrolysis (ALH, OOH, CBH) and transesterification (ALHT, OOHT, CBHT) in order to favor, then, the polymerization reactions. The analysis of the

11. Grape (Vitis Vinifera) Pomace Flour as Pigment Agent of Quail Eggs
ABSTRACT The aim of the study was to evaluate the effect of dietary grape pomace flour (GPF) inclusion on the performance and egg quality of European quails (Coturnix coturnix coturnix) in lay. One hundred ninety-two (192), 42-day-old quails were distributed in a completely randomized design with four treatments (0, 2, 4 and 6% grape pomace flour inclusion)
