摘要
研究添加不同浓度的胶体(羟丙基甲基纤维素、海藻酸钠、黄原胶)对发芽糙米面包品质的影响。结果表明,不同胶体对面包的改善作用不同,且不同食品胶适宜添加浓度不同。与未添加胶体的发芽糙米面包相比,添加2%的羟丙基甲基纤维素,面包比容增大25%,硬度降低35%,弹性增加9.5%,内聚性增加9.8%;添加0.1%的海藻酸钠,面包比容增大19%,硬度降低31%,弹性增加10%;而添加黄原胶,对高含量发芽糙米面包的品质无明显改善作用。
The effect of different hydrolloids on quality of the germinated brown rice（GBR）bread was investigated in this study,by adding different content of hydroxy propyl methyl cellulose,sodium alginate and xanthan gum.The results showed that different hydrolloids had different effects and suitable adding concentration on the bread.Compared with the GBR bread without any hydrolloids,the specific volume of bread increased by 25%, whereas its hardness decreased by 35%.However,the springiness and the cohesiveness increased by 9.5% and 9.8%,respectively,when added with 2% hydroxy propyl methyl cellulose in the bread.After adding 0.1%sodium alginate,the specific volume and the springiness of bread increased by 19% and10% respectively,while the hardness decreased by 31%.However,the xanthan gum could not improve the quality of the GBR bread.
