Abstract

Effects of partially hydrolysed guar gum (PHGG) or intact guar gum (GG) on iron utilization in rats fed on several iron-deficient diets were examined. Hemoglobin, serum iron and iron storage in liver of rats fed on iron-deficient diets as a control group (without PHGG and GG) significantly decreased, while those of the test group fed together with PHGG or GG were unchanged. In an iron balance test for 3 days, administration of PHGG or GG caused an increase in iron absorption. The results suggested that PHGG or its metabolites increase the bioavailability of dietary iron in deficiency.

摘要

研究了部分水解瓜尔胶（PHGG）或完整瓜尔胶（GG）对以几种缺铁饮食喂养的大鼠铁利用的影响。作为对照组（不添加PHGG和GG），以缺铁饮食喂养的大鼠的血红蛋白、血清铁和肝脏铁储存显著降低，而与PHGG或GG一起喂养的试验组大鼠的这些指标没有变化。在为期3天的铁平衡试验中，给予PHGG或GG会导致铁吸收增加。结果表明，PHGG或其代谢产物可提高缺铁时膳食铁的生物利用度。
