黑小豆沙加工工艺研究

Processing technology of black adzuki bean paste

以黑小豆不同浸泡温度和时间下的吸水率、不同蒸煮时间下黑小豆沙的出沙率、感官评价及质构特性为指标,研究黑小豆沙的最佳加工工艺。结果表明:黑小豆沙加工的最佳工艺参数为浸泡温度40℃,浸泡时间150 min,蒸煮时间40min,该工艺条件下黑小豆沙出沙率为(72.93±1.53)%,且质地均匀、柔软、豆香浓郁。蒸煮对硬度、黏着性、弹性、内聚性、胶黏性、咀嚼性、回复性的影响显著(P<0.05),黑小豆的蒸煮程度直接影响豆沙的品质。本研究扩大了目前豆沙原料的来源,可为黑小豆沙的工业化生产提供依据。

To make full use of the black adzuki bean resources and make black adzuki bean paste with high nutritional value, the water absorption of black adzuki beans with different soaking temperatures and time, the bean paste rate, sensory evaluation and the texture profile of different cooking time of black adzuki beans paste were de tcrmined. The research showed that the optimum process parameters of black adzuki bean paste were： soaking temperature 40℃ soaking time 150 min, cooked time 40 min; under tbis condition, the yeild rate of bean paste reached 72.93±1.53%. The making black adzuki hean paste was estimated uniform texture, soft, strong bean smell under the condition of in this process. Different cooking time had significant effects on the hardness, adhesiveness, springiness, cohesiveness, gumminess, chewiness, resilience （P〈0.05）. The quality of black adzuki bean paste was influenced by the cooked degree of black adzuki beans. Black adzuki bean could be used to peel and black adzuki bean paste with the skin to take advantage of raw material. The study has expanded the present source of raw material, and provided the basis for the industrial productions of black adzuki hean paste.
