Analysis and Evaluation of Benefits and Nutritional Quality of Different Broccoli Varieties
摘要
Abstract
[Objective]To evaluate the cultivation value of different broccoli varieties,clarify the screening criteria for varieties with benefit advantages,nutritional value advantages and comprehensive advantages,and select high-quality broccoli varieties in each dimension.[Method]Eight broccoli varieties grown in major vegetable-producing counties of Guyuan City were used as test materials.Spectrophotometry,Bradford method,phenol-sulfuric acid method and other techniques were employed to determine their appearance quality(agronomic traits,marketability,yield)and nutritional components(vitamins,soluble sugar,soluble protein,trace elements,glucosinolates,flavonoids,etc.).Analysis of variance(ANOVA),multiple comparisons(Tukey Test/Fisher Test),membership function method and comprehensive evaluation index method were used to comprehensively assess the benefits and nutritional quality of each variety,and the nutritional commonalities and individualities of the eight broccoli varieties were analyzed.[Result]There were significant differences in ap-pearance quality and nutritional quality among different broccoli varieties:①Varieties with benefit advantages:Meiqing 70 had the highest average yield(29,935.5 kg/hm²),23.80%higher than the control,with an economic benefit of 164,600 yuan/hm²,33.50%higher than the control;Zhongqing 16 and Xiyingmen followed,with yield and income increases exceeding 10%compared with the control,and all three had excellent marketability;②Varieties with nutritional value advantages:Meiqing 70 had the highest soluble protein content(19.82 mg/g);Zhongqing 16 was superior in vitamin C(63.16 mg/100g)and kaempferol(4.52 mg/100g);Xiyingmen led in soluble sugar(23.70 mg/g)and selenium(13.27 µg/100g),and all had at least 2 core indicators significantly higher than the control;③Nutritional commonalities:All varieties were rich in vitamin C(54.21-63.16 mg/100g),vitamin A(733.39-739.35 µg/100g),potassium,selenium,etc.The nutritional quality index(INQ)of mineral elements was all>1,and they contained active components such as sulforaphane(0.54-1.23 mg/100g)and kaempferol(1.97-4.52 mg/100g);④Indicators with no significant differences:There were no statistical dif-ferences in the contents of soluble solids(all 1.33 RI),potassium,calcium,etc.among varieties(P>0.05).[Conclusion]Meiqing 70 is a comprehensive advantage variety(optimal in both benefit and nutrition),Zhongq-ing 16 is a variety with prominent advantages in active components,and Xiyingmen is a benefit-nutrition bal-anced variety with leading soluble sugar and vitamin A contents.All three are superior to the control and can be popularized and planted according to production needs.关键词
