Seed oil content and selected qualitative parameters of oils from grape seeds

Antioxidant Potential of Eugenia caryophyllus, Satureja hortensis and Artemisia dracunculus Essential Oils in Grape Seed Oil

BACKGROUND: Autoxidation is an irreversible reaction which occurs with the effect of oxygen in the air, and results in unpleasant taste and smell that are known as the signs of rancidity in oil. OBJECTIVES: In this study, the antioxidant potential of clove, summer savory and tarragon essential oils (EOs) in grape seed oil was evaluated. METHODS: Effects of EOs at different concentrations (0.3, ...

Analysis of Proanthocyanidins in Grape Seed Extracts, Health Foods and Grape Seed Oils

Grape seed extract (GSE) is one of Japan's natural food additives, and is recommended for use as an antioxidant. The component of interest is polyphenol, mainly proanthocyanidins, which are condensed tannins. A vanillin-hydrochloric acid (HCl) assay is specific for flavan-3-ol. The sensitivity of GSE components to the vanillin-HCl assay differed according to the chemical structure. We applied t...

Influence of Pomegranate Seed Oil and Grape Seed Oil on Cholesterol Content and Fatty Acids Profile in Livers of Chickens.

Oils are important food ingredients, mainly as a source of unsaturated fatty acids. The offer of novel edible oils from herbs, spices and fruit seeds has grown and many of them are used as functional food and dietary supplements but also as feed additives in animal feeding. Poultry meat is recommended.in properly balanced diet and its consumption in Poland has been growing. The objective of pre...

Study of Influential Parameters on the Yield of Oil Extracted from Grape Seeds; Using Statistical Experimental Design

Alterations in seed development gene expression affect size and oil content of Arabidopsis seeds.

Seed endosperm development in Arabidopsis (Arabidopsis thaliana) is under control of the polycomb group complex, which includes Fertilization Independent Endosperm (FIE). The polycomb group complex regulates downstream factors, e.g. Pheres1 (PHE1), by genomic imprinting. In heterozygous fie mutants, an endosperm develops in ovules carrying a maternal fie allele without fertilization, finally le...
