Effect of high density planting on the quality of cold pressed rapeseed oil
摘要
Abstract
In order to determine the effect of high density planting on the quality of cold-pressed rapeseed oil,six rapeseed varie-ties with significantly different plant architectures were selected and planted with 450,000 plants hm-2 and 750,000 plants hm-2.The mature seeds were harvested and cold-pressed,and the physicochemical indexes,fatty acid composition,and typical lipid concomitants contents of rapeseed oil were analyzed.The results showed that compared with 450,000 plants hm-2,the oil content,chlorophyll,red value,peroxide value,and acid value under the density of 750,000 plants hm-2 increased on average by 4.67%,65.28%,22.16%,30.36%,and 7.23%,respectively.But all of them met the national standard gradeⅠ rapeseed oil quality stan-dard.Under the density of 750,000 plants hm-2,the contents of unsaturated fatty acids increased by 0.02%-4.26%,and the con-tents of carotenoid and polar total phenol increased by 0.52-4.54 mg kg-1 and 1.18-12.06 mg 100 g-1,respectively.At the same time,the contents of tocopherol and phytosterol of'Chuanyou 20'and'Huayouza 62'were increased.Comprehensive evaluation results showed that the quality of cold-pressed oil obtained from different plant architectures of rapeseed was different in response to the two planting densities.The quality of cold-pressed oil obtained from different heights and leaf types of rapeseed was better than 450,000 plants hm-2 under the density of 750,000 plants hm-2,among which the comprehensive quality of"Chuanyou 20"and"Huayouza 62"was superior under the density of 750,000 plants hm-2.Thus,the results of this study can provide a reference for the density planting,variety breeding,and the production of high-quality rapeseed oil raw materials.关键词
