摘要：

本研究旨在降低第三茬小果枸杞的干制成本，为外观性状欠佳的枸杞探索新加工途径，并系统测定吊干枸杞的营养与功能成分。以诺木洪种植区柴达木枸杞主栽品种‘宁杞1号’和‘宁杞7号’为研究对象，测定了吊干枸杞的外观性状、基础营养成分、活性成分，并采用电感耦合等离子体技术测定了矿质元素的含量，采用主成分分析构建柴达木吊干枸杞品质综合评价模型。研究结果显示：吊干‘宁杞1号’百粒长为164.2 cm、百粒宽为65.7 cm、百粒重为23.6 g；‘宁杞7号’的百粒长为163.3 cm、百粒宽为73.3 cm、百粒重为26.0 g；吊干枸杞‘宁杞1号’与‘宁杞7号’水分均值12.10%、灰分均值4.74%、蛋白质含量均值12.25%、粗脂肪含量均值2.75%、碳水化合物含量均值68.16%；‘宁杞1号’粗多糖含量为341 mg/g、总酚含量为2.76 mg/g、黄酮含量为4.34 mg/g、维生素C含量为40.35 mg/100g、类胡萝卜素含量为0.03 mg/g、甜菜碱含量为0.53%；‘宁杞7号’粗多糖含量为412 mg/g、总酚含量为3.10 mg/g、黄酮含量为4.58 mg/g、维生素C含量为43.44 mg/100g、类胡萝卜素含量为0.04 mg/g、甜菜碱含量为0.50%；吊干‘宁杞1号’和‘宁杞7号’枸杞之间矿质元素差别较大的为Ca、Mg；主成分分析将21项品质指标归纳为4个主成分因子，并据此建立评价模型，‘宁杞7号’样品的综合得分最高(1.94)。

Abstract:

The purpose of this study was to reduce the drying cost of the third crop of small-fruited lycium barbarum, explore new processing methods for the market lycium barbarum with poor appearance traits, and systematically determine the nutritional and functional components of hang-dried lycium barbarum. The appearance traits, basic nutrients and active ingredients of the main varieties of Qaidam Basin lycium barbarum in the Nomuhong planting area were determined, and mineral elements content was determined by inductively coupled plasma technology, and the quality evaluation model of Qaidam Basin lycium barbarum was constructed by principal component analysis. The results showed that the 100-fruit length of 'Ningqi No.1' was 164.2 cm, the 100-fruit width of 'Ningqi No.1' was 65.7 cm, and the 100-furit weight of 'Ningqi No.1' was 23.6 g. The 100- furit length of 'Ningqi No.7' was 163.3 cm, the 100- furit width of 'Ningqi No.7' was 73.3 cm, and the 100- furit weight of 'Ningqi No.7' was 26.0 g. The moisture content was 12.10%, ash content was 4.74%, protein content was 12.25%, crude fat content was 2.75%, and carbohydrate content was 68.16%. For 'Ningqi No.1', the crude polysaccharide content was 341 mg/g, the total phenol content was 2.76 mg/g, the flavonoid content was 4.34 mg/g, the vitamin C content was 40.35 mg/100g, the carotenoid content was 0.03 mg/g, and the betaine content was 0.53%; for 'Ningqi No.7', the crude polysaccharide content was 412 mg/g, the total phenol content was 3.10 mg/g, the flavonoid content was 4.58 mg/g, the vitamin C content was 43.44 mg/100g, the carotenoid content was 0.04 mg/g, and the betaine content was 0.50%. The minerals with large differences between 'Ningqi No.1' and 'Ningqi No.7' were Ca and Mg. Principal component analysis summarized 21 quality indicators into four principal component factors, and an evaluation model was established accordingly, and the comprehensive score of 'Ningqi No.7' sample was the highest (1.94).
