沙葱和油籽对羊肉中肌苷酸和腺苷酸含量的影响

文章旨在研究沙葱和油籽对羊肉中肌苷酸和腺苷酸含量的影响,为沙葱和油籽用于羊肉品质的改善提供科学依据。试验选用28只蒙古羯羊,采用完全区组试验设计,试验组分别为精料中添加4%沙葱、3种油籽(8%胡麻 2%向日葵籽 2%线麻籽)及沙葱 油籽(4%沙葱 8%胡麻 2%向日葵籽 2%线麻籽),对照组饲喂基础日粮。结果表明,添加沙葱 油籽组可显著提高背最长肌IMP的含量(P<0.05),添加4%沙葱组和3种油籽组有提高背最长肌IMP含量的趋势(P>0.05);添加4%沙葱组和沙葱 油籽组显著提高臀中肌IMP的含量(P<0.05),添加3种油籽组有提高臀中肌IMP含量的趋势(P>0.05)。添加3种油籽组显著提高背最长肌AMP的含量(P<0.05),添加4%沙葱组和沙葱 油籽组有提高背最长肌AMP含量的趋势(P>0.05);3个添加组对臀中肌AMP的含量无显著影响(P>0.05)。从结果可以看出,添加沙葱和油籽均有提高羊肉中IMP的含量,改善羊肉鲜味的作用,且沙葱 油籽组效果最好,臀中肌中IMP和AMP含量显著高于背最长肌(P<0.05)。

Effects of Allium mongolicum Regel and Oilseed ON Ionsine Monophosphate and Adenosine Monophosphate Content of Mutton

28 healthy Mongolia wethers were to used to study effects of 4% Allium mongolicum Regel,three composite oilseedss(8% Linseed 2% Sunflower seed 2%Juteseed), 4% Allium mongolicum Regel three composite oilseedss(4% Allium mongolicum Regel 8% Linseed 2%Sunflower seed 2%Juteseed)on inosine monophosphate(IMP) and adenosine monophosphate(AMP) content of mutton and provide scientific bases for producing more flavor mutton adopting single factors random experiment design as 4 groups.The results showed that in 4% Allium mongolicum Regel 8% Linseed 2%Sunflower seed 2%Juteseed group IMP content of m.longissimus dorsi was significantly increased(P<0.05),in 4% Allium mongolicum Regel and 8% Linseed 2%Sunflower seed 2%Juteseed groups IMP tended to increased(P>0.05),in 4% Allium mongolicum Regel and 4% Allium mongolicum Regel 8% Linseed 2%Sunflower seed 2%Juteseed groups IMP content of buttock muscle were significantly increased(P<0.05),in 8% Linseed 2%Sunflower seed 2%Juteseed group IMP tended to increased((P>0.05)).In 8% Linseed 2%Sunflower seed 2%Juteseed group AMP content of m.longissimus dorsi was significantly increased(P<0.05),but in 4% Allium mongolicum Regel and 4% Allium mongolicum Regel 8% Linseed 2%Sunflower seed 2%Juteseed groups AMP tended to increased(P>0.05);in tree adding groups AMP content of buttock muscle had no significant differences compared with control group(P>0.05).In conclusion,IMP contents and fresh flavor of mutton increase in three adding groups,but was best Allium mongolicum Regel oilseeds group.Contents of IMP and AMP in buttock muscle were significantly higher than those of m.longissimus dorsi.
