Abstract:

【Objective】 Fresh edible corn, which is rich in protein, amino acids, vitamins, and minerals, serves as an important resource. This study aims to systematically evaluate 31 nutritional parameters (including protein, starch, amino acids, and minerals) in nine fresh corn samples representing four varieties from five major producing regions in Xinjiang. 【Methods】 The 31 nutritional indexes (protein, starch, amino acid, mineral) were comprehensively evaluated by using analysis of variance (ANOVA) and cluster analysis. 【Results】 Black waxy corn (Jiaruize) exhibited the highest protein (4.62 g/100g), total sugar (5.80 g/100g), total amino acids (40.40 mg/g), and umami-associated amino acids content (10.43 mg/g) content (P<0.05). Its zero-amylose starch characteristic and zinc enrichment capacity (0.83 mg/100g) also provided unique processing advantages. White waxy corn (Moshangxing) demonstrated the highest VB2 (0.46 mg/100g) and total mineral content (561.29 mg/100g). 【Conclusion】 Cluster analysis categorized the nine samples into four distinct functional groups. The comprehensive evaluation identified black waxy corn (Jiaruize) from Changji as having the optimal nutritional quality.

摘要:

【目的】分析鲜食玉米富含蛋白质,氨基酸、维生素和矿物质等多种营养成分,为研究新疆不同品种鲜食玉米的营养品质特征提供参考。【方法】以新疆5大产区9个鲜食糯品种为对象,采用方差及聚类分析对鲜食糯玉米的31项营养指标(蛋白质、淀粉、氨基酸、矿物质等)进行综合评价。【结果】黑糯玉米(家瑞泽)在蛋白质(4.62 g/100g)、总糖(5.80 g/100g)、总氨基酸(40.40 mg/g)及鲜味氨基酸(10.43 mg/g)等指标含量最高(P<0.05),其零直链淀粉特性及锌富集能力(0.83 mg/100g)赋予其独特加工优势;白糯玉米(漠上行)VB2(0.46 mg/100g)及总矿物质(561.29 mg/100g)含量最高。聚类分析将9个鲜食糯玉米划分为4类,功能分异显著。【结论】9个鲜食糯玉米中,昌吉产黑糯玉米(家瑞泽)综合营养品质最优,明确了新疆鲜食玉米的营养成分和特征。
