摘要:

将叶黄素水溶性微囊粉添加至面包,研究叶黄素在面包制作以及贮藏过程中的稳定性。结果表明,和面、发酵和焙烤过程能引起全反式叶黄素含量的显著减少以及13-顺式、13’-顺式、9-顺式和9’-顺式叶黄素的生成,但焙烤对叶黄素含量的影响最大。和面和发酵过程中总叶黄素保留率下降了3.24%和5.40%;焙烤导致面包芯和面包皮中总叶黄素保留率分别下降了6.32%和41.12%。面包20 ℃避光贮藏7 d,面包芯和面包皮中总叶黄素保留率分别下降了13.64%和8.72%,色泽值基本无变化。面包贮藏稳定性良好,可以满足面包产品货架期需求。

Abstract:

Lutein is a yellow pigment with a variety of nutritional functions. The stability of lutein from bread flour fortified
with water-soluble lutein microcapsule was studied during processing steps and subsequent storage. Results showed that
dough making, fermentation and baking caused a significant reduction in all-trans lutein and the formation of 13-cis, 13’-
cis, 9-cis, and 9’-cis-lutein, but baking had the greatest influence on the content of lutein. Dough making and fermentation
caused a decrease in the retention rate of total lutein by 3.24% and 5.40%, respectively, and baking led to a reduction in the
retention rate of total lutein in bread core and bread crust by 6.32% and 41.12%, respectively. After being stored at 20 ℃
in the dark for seven days, the retention rates of total lutein in bread core and bread crust decreased by 13.64% and 8.72%,
respectively, but color value changed little. The storage stability of bread was good, which could meet the requirement for
the shelf life of bread.

Key words: lutein, stability, bread, processing, storage
