    摘要:

    研究了體外消化前,、后重結(jié)晶紅薯淀粉的益生作用及其結(jié)構(gòu)特性,。實(shí)驗(yàn)結(jié)果表明，退火處理重結(jié)晶淀粉,、溫度循環(huán)處理重結(jié)晶淀粉與濕熱處理重結(jié)晶淀粉,、體外消化后的退火處理重結(jié)晶淀粉,、體外消化后的溫度循環(huán)處理重結(jié)晶淀粉和體外消化后的濕熱處理重結(jié)晶淀粉既具有抗消化道酶降解的穩(wěn)定結(jié)構(gòu)，又能選擇性促進(jìn)人糞便中乳酸桿菌群,、雙歧桿菌群,、糞鏈球菌群和梭狀芽孢桿菌群等益生菌的增殖。與退火處理重結(jié)晶淀粉,、溫度循環(huán)處理重結(jié)晶淀粉與濕熱處理重結(jié)晶淀粉相比,，體外消化后的退火處理重結(jié)晶淀粉、體外消化后的溫度循環(huán)處理重結(jié)晶淀粉和體外消化后的濕熱處理重結(jié)晶淀粉的結(jié)構(gòu)更穩(wěn)定,，對益生菌的選擇性增殖作用也更顯著,。因此，這種重結(jié)晶淀粉完全滿足作為益生元的條件,，可作為新一代益生元產(chǎn)品進(jìn)行深入研究,。

    Abstract:

    The probiotic function and structural properties of recrystallised sweet potato starch before and after in vitro digestion were studied. The results demonstrated that the annealed, temperature-cycled and heat-moisture treated sweet potato starches before and after in vitro digestion could resist the degradation of tract enzymes and selectively promoted the proliferation of Lactobacillus, Bifidobacterium, Fecal streptococci and Clostridium septicum in human feces. Compared with the annealed, temperature-cycled and heat-moisture treated sweet potato starches, the digested annealed, temperature-cycled and heat-moisture treated sweet potato starches possessed the more stable structure as well as the higher selective proliferation of probiotics. Therefore, the recrystallised sweet potato starches could accord with the conditions of prebiotic, and be further studied as the new prebiotic product.
