This study was conducted to verify if the processing and storage of brown flaxseed whole flour result in loss of functional properties, such as reduced linolenic acid content, increased lipid peroxidation and sensory changes. The flours were obtained from seeds dried by heat treatment in oven at 150 ̊C, for 15 minutes and subsequent grinding to obtain flour with a particle size of 20 mesh. Meal ...

BACKGROUND Photoautotrophic microalgae are a promising avenue for sustained biodiesel production, but are compromised by low yields of biomass and lipids at present. We are developing a chemical approach to improve microalgal accumulation of feedstock lipids as well as high-value alpha-linolenic acid which in turn might provide a driving force for biodiesel production. RESULTS We demonstrate ...

PURPOSE This study aimed to evaluate the possible estrogenic activity of some ingredients of Nigella sativa including Linoleic acid and Gama-Linolenic acid by vaginal cornification assay. METHODS Forty ovariectomized (OVX) rats, aged 16 weeks were allotted randomly to five groups: negative control (taking 1 ml olive oil/ day); positive control (taking 0.2 mg/kg/day Conjucated Equine Estrogen-...

One of the two branches of the α-linolenic acid metabolism pathway is catalyzed by 12-oxo-phytodienoic acid reductase I, and the other is involved in jasmonic acid (JA) synthesis. The former is known to be active in the response to salinity tolerance in wheat (Triticum aestivum), but the participation of the latter in this response has not been established as yet. Here, the salinity-responsive ...

BACKGROUND The increased consumption of n-6 polyunsaturated fatty acids (PUFA) has been shown to coincide with the increased prevalence of atopic diseases. We aimed to investigate whether maternal diet and atopic status influence the PUFA composition of breast milk and the serum lipid fatty acids of infants. METHODS Maternal diet was assessed by a food questionnaire. The PUFA composition of b...

In this review the quality properties of linseed oil for food uses are discussed as well as factors affecting this quality. Linseed oil has a favourable fatty acid composition with a high linolenic acid content. Linseed oil contains nearly 60% α-linolenic acid, compared with 25% for plant oils generally. The content of linolenic acid and omega-3 fatty acids is reported to be high in linseed gro...

Emulsion fat products are a promising direction for the enrichment of unsaturated groups with fatty acids. This is possible by introducing rarely used types vegetable oils into formulations these products. Due to fact that acid composition differs depending on properties raw materials from which it produced, there need its analysis more accurate formulation emulsion product. As result conducted...

Conjugated fatty acids (CFA) have received increased interest because of their beneficial effects on human health, including preventing cancer development. Conjugated linoleic acids (CLA) are such CFA, and have been reviewed extensively for their multiple biological activities. In contrast to other types of CFAs including CLA that are found at low concentrations (less than 1%) in natural produc...

Received 22 January 2004 Revised 26 February 2004 Accepted 27 February 2004 Fungi, like plants, are capable of producing the 18-carbon polyunsaturated fatty acids linoleic acid and a-linolenic acid. These fatty acids are synthesized by catalytic reactions of D12 and v3 fatty acid desaturases. This paper describes the first cloning and functional characterization of a yeast v3 fatty acid desatur...

The effects of dietary Korean pine (Pinus koraiensis)-seed oil containing a peculiar trienoic acid (cis-5,cis-9,cis-12-18:3, pinolenic acid, approximately 18%) on various lipid variables were compared in rats with those of flaxseed (Linum usitatissimum L.) oil, safflower (Carthamus tinctorius L.) oil and evening primrose (Oenothera biennis L.) oil under experimental conditions where the effects...
