TL;DR: In this paper, a rice bran oil (RBO) deodorizer distillate using solvent at low temperature was used to extracttocopherols and tocotrienols.
Abstract: Tocols (tocopherols + tocotrienols) have been concentrated efficiently from rice bran oil (RBO) deodorizer distillate using solvent at low temperature. The levels of total tocols, total tocopherols, and total tocotrienols in RBO deodorizer distillate (starting material) were 31.5, 14.9, and 16.6 mg/g, respectively. Nine different solvents were tested, and acetonitrile was selected as the optimal solvent for concentrating tocols from the RBO deodorizer distillate. There was a significant (p <0.05) increase in the tocol level of the liquid fractions with decreasing temperature, for incubation temperatures up to -20 °C. In addition, significant differences (p <0.05) were observed in the relative percentages of α-tocopherol, γ-tocopherol, α-tocotrienol, and γ-tocotrienol between the raw sample and liquid fractions obtained at different temperatures using acetonitrile as the solvent. The concentration of the tocols from the RBO deodorizer distillate was temperature dependent, and a maximum of 89.9 mg/g was attained in the liquid fraction at - 40 °C. The relative percentage of tocotrienol homologs in the liquid fraction obtained at - 40 °C was approximately 80%. With acetonitrile as the solvent, the optimal temperature for concentrating the tocols from RBO deodorizer distillate was -20 °C when yield was considered.

Abstract: The invention discloses a pomegranate peel feed for chicken. The feed is prepared from the following raw materials in parts by weight: 50-55 parts of cornmeal, 15-20 parts of cottonseed meal, 5-8 parts of rice bran meal, 5-8 parts of wheat meal, 22-26 parts of soybean meal with content of crude proteins being more than 48%, 3-6 parts of corn protein meal, 0.5-1 part of fish meal, 1-2 parts of apple leaf meal, 1-2 parts of feed-grade dicalcium phosphate, 0.3-0.8 part of rice bran oil, 0.2-0.4 part of salt, 0.1-0.3 part of choline chloride, 0.1-0.2 part of lysine, 0.1-0.2 part of methionine, 2-4 parts of oil residues, 0.4-0.8 part of multi-vitamin, 0.5-1 part of seabuckthorn oil, 0.1-0.5 part of loofah lyophilized meal, 15-25 parts of fresh brewer's grains, 2-5 parts of Muyu stone meal, 3-5 parts of pomegranate peel meal, 0.1-0.4 part of zeolite meal pickled in vinegar, 0.5-1 part of bitter orange petal meal, 1-2 parts of peanut kernel meal and 4-6 parts of traditional Chinese medicine additives. The feed has the beneficial effects that the utilization rate of the feed is improved, the feed conversion ratio is reduced and growth is promoted.

TL;DR: In this paper, the effects of three high monounsaturated edible oils with different fatty acid compositions on plasma lipid metabolism in man were investigated, and the reducing effects of the rice bran oil and soybean oil diets on percent changes of the plasma total lipids, total cholesterol and LDL-C were significantly larger (P P S and P+M S ratio of various edible oils had no consistency with the responses of plasma lipids).

TL;DR: Results provided the first mass spectrometric evidence suggesting that a portion of orally administered OZ is directly absorbed by the intestine and is present in the intact form in plasma, which may explain the beneficial effects of OZ in vivo.
Abstract: Although the beneficial effects (e.g., lipid-lowering activity) of γ-oryzanol (OZ), a mixture of ferulic acid esters of plant sterols and triterpene alcohols, have been extensively investigated, few studies have evaluated the absorption and metabolism of OZ. Moreover, it is unclear whether OZ, once ingested, is directly absorbed by the intestine into the bloodstream at a sufficient level to exhibit activity. Here, we prepared OZ concentrate from purified rice bran oil (Rice Oil OZ), determined the concentration of OZ in the preparation (cycloartenyl ferulate equivalent concentration; 52.2%), and then carried out chromatography-mass spectrometry analysis of plasma samples from mice after oral administration of Rice Oil OZ. The OZ concentrations of plasma from the control (vehicle-treated) mice were low (trace levels); however, at 5 h after a single oral administration of the Rice Oil OZ (600 mg per kg body weight), the levels significantly increased, reaching 17.6 ng mL−1 for cycloartenyl ferulate, 28.2 ng mL−1 for 24-methylenecycloartanyl ferulate isomers, 15.6 ng mL−1 for campesteryl ferulate, and 5.1 ng mL−1 for β-sitosteryl ferulate, respectively, expressed in equivalence of cycloartenyl ferulate in plasma. These results provided the first mass spectrometric evidence suggesting that a portion of orally administered OZ is directly absorbed by the intestine and is present in the intact form in plasma. The presence of a significant amount of OZ in its intact form in plasma may explain the beneficial effects of OZ in vivo.
