本研究旨在探讨红枣水溶性浓缩糖（WSCC）对金黄地鼠不同肠道和粪便指标的影响。WSCC含有碳水化合物（771 g kg（-1）WSCC），包括葡萄糖、果糖、果胶多糖和半纤维素。WSCC的管理（5.0和15 g kg（-1）饲料）有效缩短胃肠通过时间（P < 0.05）（34.2-57.3%），盲肠氨减少（58.1-60.3%），盲肠中总短链脂肪酸浓度升高（3-4倍），粪便水分增加（147-170%），减少每日粪便氨排出量（31.9-75.8%），降低β-D-葡萄糖醛酸酶活性（73.0-73.8%）、β-D-葡萄糖苷酶（58.2-85.7%）、粘蛋白酶（46.2-72.6%）和尿素酶（31.9-48.7%）。本研究提示，适量食用红枣WSCC（至少5.0 g/kg或40 mg/d）可改善胃肠道环境，减少肠粘膜对有毒氨和其他有害化合物的暴露。
This study was to investigate the effects of water-soluble carbohydrate concentrate (WSCC) prepared from Chinese jujube (Zizyphus jujuba) on different intestinal and fecal indices in a hamster model. WSCC contained carbohydrates (771 g kg(-1) of WSCC) including glucose, fructose, pectin polysaccharide, and hemicellulose. The administration of WSCC (5.0 and 15 g kg(-1) of diet) effectively (P < 0.05) shortened gastrointestinal transit time (by 34.2-57.3%), reduced cecal ammonia (by 58.1-60.3%), elevated total short-chain fatty acid concentrations in cecum (3-4-fold), increased fecal moisture (147-170%), reduced daily fecal ammonia output (by 31.9-75.8%), and decreased the activities of beta-D-glucuronidase (by 73.0-73.8%), beta-D-glucosidase (by 58.2-85.7%), mucinase (by 46.2-72.6%), and urease (by 31.9-48.7%) in feces. This study suggested that adequate consumption of jujube WSCC (at least 5.0 g kg(-1) of diet or 40 mg day(-1)) might exert favorable effects on improving the gastrointestinal milieu and reducing the exposure of intestinal mucosa to toxic ammonia and other detrimental compounds.
