Absorption difference between diacylglycerol oil and butter blend containing diacylglycerol oil

Abstract

This study aims at investigating whether the intake of butter blends containing diacylglycerol (DAG) oil may result in reduced fat accumulation, in similarity to DAG oil, and the potential metabolic differences between butter blends and DAG oil. Four experimental diets containing either 10 wt% DAG butter blend (BDAG), triacylglycerol (TAG) butter blend (BTAG), DAG oil (ODAG) or TAG oil (OTAG) were prepared, and each was fed to a group of 8 male Wistar rats. The design of the experiment was a combined balance and feeding experiment. The rats fed the BTAG and ODAG‐diets had a significantly higher protein content than rats fed the BDAG and OTAG‐diets, and the fat content was significantly lower in rats fed the ODAG‐diet as compared to rats fed the OTAG and BDAG‐diets. A significantly higher content of ash was observed in rats fed the two TAG diets. The ratio of abdominal fat weight/body weight was significantly higher for rats fed the BDAG‐diet than for rats fed the BTAG and ODAG‐diets. To conclude, the beneficial effects of DAG oil in reducing body fat accumulation cannot be observed in DAG oil containing butter blends, and the effect of DAG on bone health requires further investigation.

Comparative in vitro intestinal digestion of 1,3-diglyceride and 1-monoglyceride rich oils and their mixtures

“…The 1,3-DG has been reported as a hypocaloric lipid that decreases weight, body fat and serum triglycerides (TG), or increases energy expenditure; but the mechanism of these effects is still under intense research (Dhara, Dhar, & Ghosh, 2013;Jandacek, 2007;Kristensen, Jørgensen, & Mu, 2012;Lo, Tan, Long, Yusoff, & Lai, 2008;Meng, Zou, Shi, Duan, & Mao, 2004;Murase, Aoki, Wakisaka, Hase, & Tokimitsu, Food Research International 64 (2014) Rudkowska et al, 2005;Yanai, Yoshida, Hirowatari, & Tada, 2012;Yanai et al, 2010). The most popular mechanism has been related to the metabolism of 1,3-DG within the enterocyte.…”
