【摘要】 对大头鲤、黑龙江鲤、德国镜鲤及杂种F3背部肌肉的肉色、嫩度、pH、失水率、系水力和肌纤维性状进行研究,评价杂种F3的肌肉品质。结果表明:(1)杂种F3肌肉的亮度为47.37,红度为1.85,黄度为3.27,嫩度为1.65kg.f,pH为6.62,失水率为22.54%,系水力为97.30%,肌纤维的横截面积为128.76μm2,纤维的密度为183.38根每平方毫米,肌纤维面积的比例为55.55%。(2)杂种F3与亲本肌肉品质的比较,肉色亮度与黑龙江鲤相近,高于大头鲤和德国镜鲤;红度与大头鲤和黑龙江鲤相近,低于德国镜鲤;嫩度与大头鲤相近,小于黑龙江鲤和德国镜鲤;肌纤维的横截面积与大头鲤相近,小于黑龙江鲤和德国镜鲤;肌纤维密度与大头鲤相近,大于黑龙江鲤和德国镜鲤;pH、失水率、系水力、肉色的黄度和肌纤维面积的比例与3亲本差异不显著。研究表明杂种F3具有与大头鲤相似的肌肉品质,经进一步选育可以育成一个优质的鲤新品系。更多还原

【Abstract】 In order to compare the flesh quality of hybrid F3 and its parents of Big-head carp, Amur carp and German mirror carp,the muscle color,tenderness,pH,holding water capacity, losing water capacity and the fiber characteristic were studied in this paper.The results showed that:1) For the hybrid F3,the lightness was 47.37,redness was 1.85,yellowness was 3.27, tenderness was 1.65kg·f,pH was 6.62,losing water capacity was 22.54%,holding water capacity was 97.30%,the fiber cross section was 128.76μm2 and the fiber density was 183.38 fiber.mm-2,the ratio of fiber area to unit area is 55.55%.2) Comparison between hybrid F3 and its parents,The brightness of F3 was near the Amur carp,but was higher than Big-head carp and German mirror carp;the redness was near Big-head carp and Amur carp,but was lower than German mirror carp;the tenderness of F3 is near the Big-head carp,but lower than Amur carp and German mirror carp;the fiber cross section was near the Big-head carp,but lower than Amur carp and German mirror;the fiber density was near the Big-head carp,but higher than Amur carp and German mirror;and there are no significant differences of pH, losing water capacity,holding water capacity,muscle yellowness and the ratio of fiber area to unit area between the hybrid F3 and the parents.The results showed that the hybrid F3 has inherited the better flesh quality,which was near the Big-head carp,and the hybrid carp can be cultivated to be a good aquaculture species.更多还原
