郑州地区野生贼小豆资源特性研究初报

以郑州地区野生贼小豆为材料,阐述了野生贼小豆的部分特性,采用国标方法和传统方法对其籽粒形状、千粒重、容重、果荚出果率、粒度变幅、自流角、含水量、酸度等15项理化指标进行了测定,以期为贼小豆自然野生资源的种植、加工和开发利用提供最基本的科学依据.结果表明:贼小豆籽粒为椭圆型褐色小粒,千粒重为27.1176～28.1799 g,不完善粒小于2％,酸度为每10 g贼小豆样品中含H+ 8.0～8.6 mmol,容重为807.5～809.5 g/L,相对密度在1.25～1.28之间,水分含量范围为9.43％～9.60％,平均净度为95.09％,自流角平均值为14.3°,静止角为31.9°,果荚平均出果率为66.72％,果荚比率平均为2.00.贼小豆在我国传统食品领域有一定的开发应用前景.

Preliminary study of resources characteristics to Vigna minima (Roxb.) in zheng zhou region

In order to provide basic scientific basis for the natural wild resource cultivation, processing and utilization in Vigna minima (Roxb.), the grain shape, thousand seeds weight, bulk density, pod fruit rate, particle size range, angle of gravity, water content,acidity and so on 15 the physical and chemical indicators were determined by the national standard and traditional method with Wild Vigna minima (Roxb.) for materials in Zhengzhou region, and also the characteristics were expounded. Results showed that the grains of Vigna minima (Roxb.) were elliptic brown small grain, thousand seeds weight were 27.1176~28.1799 g, imperfect grains were less than 2% and the acidity between 8.0~8.6 mmol H+ /10g, bulk density were 807.5~809.5 g/L, relative density between 1.25~1.28, water containing amount range were 9.43%~9.60%, average clarity was 95.09%, their average angle was 14.3 degrees, repose angle was 31.9degrees, the rate of fruit was 66.72%, pod ratio was 2.00 on average. Vigna minima (Roxb.) has a certain development application prospect in the field of Chinese traditional food.
