Whole-grain rye and wheat foods and markers of bowel health in overweight middle-aged men.
Whole-grain cereal foods including rye have been identified as providing significant health benefits that do not occur when refined-cereal foods are ingested.. Foods (90 g) containing whole-grain rye flour and whole-grain wheat flour were compared with low-fiber refined-cereal foods for their effects on markers of bowel health and the metabolic markers insulin and glucose.. Three 4-wk interventions were undertaken in a randomized crossover design with 28 overweight men aged 40-65 y who had no history of bowel disease. Against a background intake of 14 g dietary fiber (DF), the men were fed low-fiber cereal grain foods providing 5 g DF for a total of 19 g DF/d. High-fiber wheat foods provided 18 g DF, and high-fiber rye foods provided 18 g DF, both giving a total of 32 g DF/d. Fecal samples (48-h) and fasting and postprandial blood samples were collected at the end of each period and assayed.. Both high-fiber rye and wheat foods increased fecal output by 33-36% (P = 0.004) and reduced fecal beta-glucuronidase activity by 29% (P = 0.027). Postprandial plasma insulin was decreased by 46-49% (P = 0.0001) and postprandial plasma glucose by 16-19% (P = 0.0005). Rye foods were associated with significantly (P = 0.0001) increased plasma enterolactone (47% and 71%) and fecal butyrate (26% and 36%), relative to wheat and low-fiber options, respectively.. High-fiber rye and wheat food consumption improved several markers of bowel and metabolic health relative to that of low-fiber food. Fiber from rye appears more effective than that from wheat in overall improvement of biomarkers of bowel health.

A highly efficient microextraction technique based on deep eutectic solvent formed by choline chloride and p-cresol for simultaneous determination of lignans in sesame oils.
For simultaneous determination of lignans (i.e. sesamin, sesamolin and sesamol) in sesame oils, a highly efficient ultrasonic-assisted liquid-liquid microextraction (UALLME) technique was developed based on deep eutectic solvents (DESs) composed of choline chloride and p-cresol. Compared with the common polyols-based DESs (i.e. choline chloride-ethylene glycol), the phenolic DESs exhibited higher extraction efficiency for both polar lignans (i.e. sesamol) and non-polar lignans (i.e. sesamin and sesamolin) due to the π-π interaction between lignans and DES. After the UALLME process, DES phase was analyzed by HPLC-UV. Under optimized condition, all three lignans showed good linear calibration curves and low limit of detection. The recoveries were in the range of 97.3-120%, and the intra-day and inter-day precisions were less than 0.97%. Moreover, this method was used for simultaneous determination of lignans in 15 commercial oil samples. The results showed that the new microextraction technique achieved similar efficiency as the conventional liquid-liquid extraction method.
