This paper presents a new method to lubricate, cool, and evacuate chips in metalworking operations using supercritical carbon dioxide (scCO2). Water-based and straight oil metalworking fluids (MWFs) are currently being used to perform these functions even though they are characterized by high economic, occupational health, and environmental costs. Carbon dioxide above its critical temperature a...

The influence of frying with four different oils (sunflower oil, soybean oil, olive oil, and corn oil) on the fatty acid composition of silver carp was evaluated. The fat content of the fillets increased after frying while the moisture content decreased in all evaluated samples. Mean saturated (SFA), monounsaturated (MUFA), polyunsaturated (PUFA) fatty acids, ∑ω3, and ∑ω6 contents of raw fish w...

The use of coconut oil in human nutrition and diet and its effect on the cholesterol level were investigated at the New England Deaconess Hospital, at Harvard affiliate. Based on the study, consumption of up to 50% of dietary fat as coconut oil does not significantly alter either total cholesterol or LDL cholesterol in otherwise healthy young men. Coconut oil when included in a well-balanced di...

Fish oil and shortening have been suggested to have opposite effects on cardiovascular disease (CVD). This study investigated the effect of shortening and fish oil on CVD risk factors and aorta histopathology, and the association between risk factors and aorta histopathology. Male Wister rats (n=30) were fed an AIN-93G diet containing 20% fat in the form of fish oil, shortening, or soybean oil ...

background: considering the wide consumption of some synthetic antioxidants and their probable negative health effects, in this study, the protective effects of satureja hortensis l. extracts in stabilizing soybean oil against oxidation at different concentrations (200 and 400 ppm) were tested. methods: the aerial parts of s. hortensis l. were collected from isfahan province and extracted with ...

This study was conducted with broilers to evaluate the effects of growth-promoting antibiotic (flavomycin) and probiotic (7 bacterial species) supplementation in diets containing soybean oil or free fatty acids (FFA) on performance, morphological parameters of the small intestine, apparent digestibility of gross energy (GE) in the ileum, and apparent digestibility of fat in the ileum and total ...

Fluorescence spectra of some common vegetable oils, including olive oil, olive residue oil, refined olive oil, corn oil, soybean oil, sunflower oil, and cotton oil, were examined in their natural state, with a wavelength of 360 nm used as excitation radiation. All oils studied, except extra virgin olive oil, exhibited a strong fluorescence band at 430-450 nm. Extra virgin olive oil gave a diffe...

BACKGROUND Soybean oil lipid emulsion may compromise immune function and promote hepatic damage due to its composition of long-chain fatty acids, phytosterols, high proportion of ω-6 fatty acids, and low α-tocopherol levels. Combination lipid emulsions have been developed using medium-chain triglyceride oil, fish oil, and/or olive oil, which provide adequate essential fatty acids, a smaller con...

Epoxidized vegetable oils are the product of vegetable oil epoxidation reactions. Since the epoxidized vegetable oil is a nonpoisonous plasticizer, it has been wildly used in the plastic packaging of food and medicine. Among the various epoxidized vegetable oils, the application of epoxidized soybean oil is broader than others. Nowadays, it’s the third largest category of plasticizers. However,...

To evaluate the effect of adding calcium salt of soybean oil on the performance and growth of suckling calves, 18 Holstein calves, after the birth with weight average 3.94 ± 42.43 kg were randomized into three groups. The experimental allotments including: 1) the starter without calcium salt of soybean oil (control), 2) starter with 0.3% calcium salt of soybean oil and 3) starter containing 0.5...
