不同小麦糊粉层粉添加量对馒头品质的影响

    Effect of different addition of wheat aleurone flour on the quality of steamed bread

    • 摘要: 为提高传统馒头的营养品质和食用品质,以小麦糊粉层粉代替部分小麦粉制作馒头。挤压处理的小麦糊粉层粉按照0%、5%、10%、15%、20%、25%、30%、35%添加至小麦粉中,采用酵子和酵母2种不同的发酵方式制作馒头,对馒头的质构特性、比容、色泽、宽高比、感官评分等进行测定,对不同添加量的糊粉层粉制作的酵子馒头与酵母馒头的综合品质进行评价。研究结果表明:酵子馒头的感官评分、比容、质构分析、色泽等综合评价整体高于酵母馒头,更容易被消费者接受。采用酵子发酵剂蒸制糊粉层粉馒头其糊粉层粉的最适添加量为10%~15%,采用酵母发酵剂在糊粉层粉添加量为5%~10%蒸制的馒头品质较佳。高添加量的糊粉层粉馒头硬度较大,口感较差,消费者能接受的最大添加量为30%。小麦糊粉层粉的适量添加不仅可以保留馒头的原有品质,还可以平衡营养组分,有助于改善馒头的品质。

       

      Abstract: Steamed bread, one of the traditional staple foods of the Chinese nation, is becoming increasingly popular in other Asian countries. With the rapid development of China's economy, science, and technology, steamed bread production in China has switched from the small family workshop to industrial production. In order to save time and cost, industrialized steamed bread is mainly fermented by yeast, however, a single strain usually lead to dull flavor and simple taste. Meanwhile, as a part of Chinese traditional pasta culture, Jiaozi is also used for the fermentation of steamed bread that performs unique taste and flavor. To improve the eating quality of traditional steamed bread, wheat aleurone layer powder was used to replace some wheat flour to make steamed bread. In this paper, the extruded wheat aleurone flour was added into wheat flour at the dosage of 0, 5%, 10%, 15%, 20%, 25%, 30%, and 35% respectively. Jiaozi and yeast fermentation methods were used to produce steamed bread. Texture analysis, specific volume, chromatic aberration, aspect ratio and sensory evaluation were used to evaluate the eating quality of the steamed bread. The comprehensive quality of Jiaozi steamed bread and yeast steamed bread made with different adding amount of aleurone layer powder was evaluated to provide theoretical basis for the research and development of aleurone layer powder and industrial production of steamed bread. The results showed that the sensory score, specific volume, texture analysis, color difference and other comprehensive evaluation of Jiaozi steamed bread were higher than yeast steamed bread, and it had higher acceptance by consumers. The optimum addition range for steamed bread of aleurone layer flour by using Jiaozi starter is 10%-15%, while that by using yeast starter is less than 10%. Thus, the optimum addition range for the steamed bread of aleurone layer flour by using yeast starter is 5%-10%. The maximum additive amount of aleurone layer powder steamed bread accepted by consumers is 30%. Too much wheat aleurone layer flour added into wheat flour will lead to high hardness of steamed bread, rough taste, and difficulty in acceptance. Therefore, proper addition of wheat aleurone layer flour could not only retain the original quality of steamed bread, but also balance the nutritional components of steamed bread.
