| 摘 要： | 为了解不同干燥方法对即食扇贝柱干燥后品质的影响，以海湾扇贝柱为原料，研究了微波干燥、真空冷冻干燥、自然干燥和烘箱干燥4种方法对即食扇贝柱理化特性和感官品质的影响。结果表明：不同干燥方法所得产品在水分活度、pH值、硬度、咀嚼性和黏聚性方面存在着显著性差异，不同干燥方法对产品的色泽和弹性影响均不显著；烘箱干燥产品感官品评得分8.82分，其氨基酸总量最高，微波干燥氨基酸总量最低；真空冷冻干燥后产品中必需氨基酸和呈味氨基酸含量最高，自然干燥最低。综合考虑，烘箱干燥是即食扇贝柱较适宜的干燥方法，产品感官品质和氨基酸总量较高。较佳的烘箱干燥参数为：80℃干燥2 h。研究结果可以为即食扇贝柱的工业化生产提供参考。 |

| Abstract: | The effects of different drying methods(i.e.microwave drying,vacuum freeze drying,natural drying and oven drying) on the quality of instant scallop were investigated.The bay scallop was chosen as the raw material,furthermore,two significant parameters,the physicochemical properties and sensory characteristics were tested in detail.The results showed that water activity,pH value,hardness,chewiness and cohesiveness of product have significant variation with different drying methods.The statistics results of t... |
