Abstract:

In order to explore the difference of nutritional components between fresh and mature broad beans in different regions, and to provide data support for breeding and popularization of broad beans. In this study, protein, vitamins, mineral elements, amino acids and other nutrients of broad beans from different sources were analyzed. The dietary fiber content of fresh and mature seeds of Jiading ‘Sanbai’ broad beans is high, and the Ca content and Fe content are higher than those of broad beans in other regions. The content of vitamin B1 and B2 in Jiading ‘Sanbai’ mature kernel is high. The amino acid composition of Jiading ‘Sanbai’, other faba beans and Japanese broad beans is similar, which further confirms that Jiading white broad beans and Japanese broad beans have a certain correlation. Jiading ‘Sanbai’ is an excellent broad beans germplasm resource, which is suitable for further development and utilization.
