摘要: 为降低魔芋育种成本、缩短育种年限,采用小型粉碎机粉碎,烘箱烘烤样品对魔芋品质进行分析。结果表明,仅需600 g鲜芋就能准确测定一份样品的含水量、出粉率和精粉黏度,含水率测定值绝对偏差在0.3%以内,出粉率测定值绝对偏差在0.16%以内,精粉黏度测定值绝对偏差远小于NY/T494—2010中规定的二次独立测定结果的绝对差值不超过1 000 mPa.s,该方法为魔芋优良种芋的选育提供了重要的参考依据,为加快魔芋育种进程奠定了基础。

Abstract: In order to reduce breeding cost and shorten breeding years, the quality of konjac was analyzed by means of oven baking a few samples and small pulverizer grinding. The results showed that only 600 g fresh konjac could accurately measure the water content, powder yield and viscosity of a sample, absolute deviation of moisture content measurement value was within 0.3%, absolute deviation of powder yield measurement value was within 0.16%, the absolute deviation of the determination value of the viscosity of fine powder was far less than that of the secondary independent determination result specified in the national standard for agricultural industry NY/T494—2010, which was less than 1 000 mPa.s. This method provided an important reference for the selection and breeding of konjac superior varieties, and laid a foundation for accelerating the breeding process of konjac.

Key words: konjac, quality, analysis
