BACKGROUND Plant cell walls are known to influence the rate and extent of lipid release from plant food tissues during digestion; however, the effect of cell wall structure on postprandial lipemia is unknown. OBJECTIVE The objective was to investigate the effects of lipid release (bioaccessibility) on postprandial lipemia by comparing lipid encapsulated by cell walls with lipid present as fre...

Two studies with growing pigs were conducted using the regression analysis technique to estimate the true digestibility of P (TPD) in canola (CM) and soybean (SBM) meals, and quantify the effect of microbial phytase on TPD of CM and SBM. In each study, 48 (Exp. 1) or 36 (Exp. 2) 17-kg barrows were assigned to 6 dietary treatments arranged in a 3 x 2 factorial of 3 graded levels of CM (Exp. 1) o...

BACKGROUND The process of randomization is used commercially to harden fats as an alternative to partial hydrogenation, but its effects on cardiovascular disease risk factors are uncertain. OBJECTIVE The objective was to compare the chronic and acute effects of randomization of a fat rich in 1,3-distearyl, 2-oleyl glycerol on fasting and postprandial lipids, glucose, insulin, and activated cl...

The present study evaluates the influence of different amounts of fat added to starch on postprandial glucose metabolism (exogenous and endogenous). Nine women (24 (se 2) years old, BMI 20.4 (se 0.7) kg/m(2)) ingested 1 week apart 75 g glucose equivalent of (13)C-labelled starch in the form of pasta without (low fat; LF) or with 15 (medium fat; MF) or 40 (high fat; HF) g sunflower oil. During t...

Binary blends of palm olein (PO) with sunflower oil (SFO), canola oil (CNO), and cottonseed oil (CSO) were formulated to assess their stability under continuous frying conditions. The results were then compared with those obtained in PO. The oil blends studied were: (1) 60:40 for PO + SFO; (2) 70:30 for PO + CNO; and (3) 50:50 for PO + CSO. The PO and its blends were used to fry potato chips at...

Cold-pressed canola cake is a coproduct of biodiesel production that contains more residual oil than expeller-pressed and solvent-extracted canola meal. Cold-pressed canola cake might be an attractive feedstuff for swine due to local availability from small plants. However, the nutritional quality and content of anti-nutritional factors of cold-pressed canola cake are poorly defined and vary wi...

Abstract This study investigated an alternative approach to valorizing canola proteins by hydrolyzing them generate amino acids (AAs). Pre‐treatment of cold‐pressed (CP) cake and desolventized‐toasted (DT) meal with ethanol (99%, vol/vol) followed protein separation was studied as process optimizations maximize recovery higher purity. The optimum pre‐treatment conditions achieve a containing le...
