Analysis of Correlation between the Slaughter Performance and Meat Quality of Frizzle Chicken
2014年
[Objective]This study aimed to evaluate the meat quality of frizzle Chick-en, and to find out the correlation between the meat quality and slaughter perfor-mance. [Method] The slaughter performance such as live chicken weight, carcass weight, semi-eviscerated weight, eviscerated weight, chest muscle weight, leg mus-cle weight, abdominal fat weight and the meat quality indices like color, pH and shear force of 12-week-old frizzle chickens were measured to analyze the correla-tion between slaughter performance and meat quality. [Result] The carcass percent-age, semi-eviscerated percentage, eviscerated percentage, chest muscle percentage, leg muscle percentage, abdominal fat percentage, intramuscular fat width and subcu-taneous fat thickness of the male chickens were 89.76%, 81.54%, 67.53%, 7.82%, 11.29%, 2.42%, 0.69 cm and 0.48 cm, of female chickens were 89.78%, 80.87%, 62.94%, 6.19%, 9.92%, 3.91%, 0.78 cm and 0.61 cm. Some of these traits exhibit-ed significant difference between the male and female chickens (P〈0.05). In male chickens, the chest muscle color, pH and shear force were 5.93, 6.15 and 3.72 kg, and the leg muscle color, pH and shear force were 6.18, 6.54 and 3.41 kg; in fe-male chickens, the chest muscle color, pH and shear force were 5.77, 6.05 and 3.41 kg, and the leg muscle color, pH and shear force were 6.03, 6.21 and 2.74 kg. The quality of chest and leg muscles of frizzle chickens significantly differed (P〈0.05). Carcass weight had significant positive correlations with semi-eviscerated weight and meat color (P〈0.05), and an extremely significant positive correlation with pH (P〈0.01). Semi-eviscerated weight and pH value shared a significant posi-tive correlation (P〈0.05). Eviscerated weight and leg muscle weight shared an ex-tremely significant negative correlation (P〈0.01). Abdominal fat weight correlated sig-nificantly and negatively with shear force (P〈0.05). Meat color and pH value had a significant positive correlation (P〈0.05). [Conclusion]

柚皮果酱制备工艺研究被引量:9
2014年
探索利用柚子皮下脚料来研制具有独特风味的果酱食品。采用盐碱法优选最佳的柚皮脱苦方案,通过单因素试验和正交试验确定柚皮果酱的最佳工艺条件为糖量/果酱0.8∶1.0,添加0.15%柠檬酸调试p H值至3.0,并添加0.8%β-环糊精对果酱起到脱苦除涩的作用,制得的果酱具有独特的柚子香味,甜酸适中,口感舒适。
