六盘水市六枝特区牛场辣椒品质分析

Quality Analysis of Niuchang Pepper of Liuzhi Special Zone in Liupanshui City

为了测定牛场辣椒单椒重、果型指数等感官形态和辣椒碱、辣椒红色素含量,分析牛场辣椒的品质,本试验随机抽取牛场鲜辣椒与干辣椒各50个,用分光光度法检测辣椒碱和辣椒红色素含量,用蒽酮比色法检测可溶性糖含量,用灼烧重量法检测灰分含量。结果表明,牛场鲜椒中叶绿素与类胡萝卜素的含量分别为1.314 mg/L及4.530 mg/L;牛场干辣椒中辣椒红色素的含量为170.271 mg/kg,辣椒碱含量为1.652%,可溶性糖含量差异极显著(P<0.01)。牛场辣椒的辣椒碱、辣椒红色素、可溶性糖含量等理化性状明显优于贵州地区其他牛角椒,是具有独特地方特色的牛角辣椒品系。

In order to determine the sensory morphology(individual fruit weigh,fruit type index and so on) and the content of capsaicin and capsanthin of Niuchang pepper,and analyze the quality of the pepper,50 fresh fruits and 50 dry fruits were randomly selected in this experiment to detect the content of capsaicin and capsanthin by spectrophotometry,soluble sugar by anthrone-colorimetric method,and ash by cauterization gravimetric method.The results showed that the content of chlorophyll and carotenoid in fresh fruit was 1.314 mg/L and 4.530 mg/L,respectively.The content of capsanthin and capsaicin in dry fruit was 170.271 mg/kg and 1.652%,respectively;the difference of soluble sugar content was extremely significant(P<0.01).Physical and chemical properties of Niuchang pepper(the content of capsaicin,capsanthin and soluble sugar etc.)were obviously better than those of other cattle-horn pepper in Guizhou.In conclusion,Niuchang pepper is a unique cattle-horn pepper strain which has local characteristics.
