Diacylglycerol (DAG) may undergo differential metabolism compared with triacylglycerol (TAG) in humans, possibly resulting in decreased serum TAG concentration and TAG synthesis and increased energy expenditure (EE), thus reducing fat accumulation. Our objective was to examine the efficacy of DAG oil (Enova oil) consumption on serum lipid profiles, hepatic lipogenesis, EE, and body weight and c...

The objective of the study was to investigate the effects of supplementing different plant oils to the basal diet on milk yield and milk composition in mid-lactating dairy cows. Forty Chinese Holstein dairy cows averaging 120 days in milk (DIM) at the start of the experiment (body weight = 580 ± 18.2 kg; milk yield = 33.0 ± 2.00 kg/day) were used in a completely randomized block design. The ani...

Biodiesel is a promising non-toxic and biodegradable alternative fuel in transport sector. Of all the biodiesel properties, specific gravity and viscosity are the most significant for the effects they have on the utilization of biodiesel fuels in unmodified engines. This paper presents models, which have been derived from experimental data, for predicting the specific gravity and dynamic viscos...

Sunflower (Helianthus annuus L.), belonging to the family „Asteraceae‟ is a diploid species (2n = 2x = 34). Sunflower is an important oilseed crop and is the preferred source of oil for domestic consumption and cooking worldwide (Hu et al., 2010). In the oilseed scenario, sunflower competes with other three major oilseeds, i.e. soyabean, groundnut and rapeseed mustard at global level. Sunflower...

Near-infrared spectroscopy (NIRS) was used as a rapid and nondestructive method to determine the fatty acid composition in intact seed samples of rapeseed (Brassica napus L.). A total of 349 samples (about 2 g of intact seeds) were scanned in the reflectance mode of a scanning monochromator, and the reference values for fatty acid composition were measured by gas-liquid chromatography. Calibrat...

Rapeseed (Brassica napus L.): We analyzed a total of n = 136 rapeseed in-breds proprietary to Norddeutsche Pflanzenzucht Hans-Georg Lembke KG (Holt-see, Germany). In 2004, all entries were evaluated in a series of field trials. All trials included a set of three common checks and were conducted at Hohenlieth and Malchow (Germany). The experimental design of each trial was a 6×6 lattice design w...

We have earlier reported the reduction of total cholesterol, low-density lipoprotein (LDL) cholesterol and oxidized LDL caused by short-term modification of diet with cold-pressed turnip rapeseed oil (CPTRO) instead of butter. The aim of this supplementary study was to determine whether the beneficial effects resulted from altered cholesterol metabolism during the intervention.Thirty-seven men ...

Nonylphenol (NP) has been suspected as an endocrine-disrupting chemical. Japanese polyvinyl chloride (PVC) stretch films contained 0.5-3.3 mg/g of NP and 100-400 mg/g of plasticizers such as diisononyl adipate (DINA), di-n-alkyl adipate (DAA), and diacetyllauroyl glycerol (DALG). Migration of NP and plasticizers from PVC stretch films into food simulants (water; 4% acetic acid; 20%, 50%, and 95...

Relationship among malondialdehyde (MDA), 2-thiobarbituric acid (TBA)-reactive substances (TBA-RS), and tocopherols in the oxidation of rapeseed oil was investigated. MDA was determined by a new HPLC method with chemical derivatization. When the oil was heated at 170 degrees C, TBA-RS and MDA increased. The contents of TBA-RS were approximately 1.6 times higher than those of MDA. Correlation be...
