中文摘要:
      以湘西南主栽黑老虎品种“湘黑–0701”的果实为材料,研究其果皮、果肉果汁、种子和果芯4部分的基本加工特性和主要营养成分。结果表明:果皮在聚合果中占比(42.48%~47.70%)最大,出汁率低;果肉果汁在聚合果中占比(35.01%~37.47%)较大,且果肉果汁较为浑浊,L*、a*和b*值均最小,总糖质量分数(5.27%)和还原糖质量分数(2.34%)最高;种子苦涩味明显且含有厚实种壳,在聚合果中占比(7.65%~11.16%)小,灰分质量分数(7.20%)、蛋白质质量分数(11.14%)和粗脂肪质量分数(21.70%)均最高;果芯在聚合果中占比(8.21%~11.21%)小。果皮、果肉果汁、种子和果芯4个部分中的矿质元素均以钾含量最高,分别达3 952.17、2 064.10、4 900.43、2 937.40 mg/kg;维生素含量则以胆碱含量最高,其含量分别达590.33、621.67、692.33、248.33 mg/(100 g)。鉴于黑老虎各部分加工特性和主要营养成分的差异,可分别用于不同类型健康产品的开发。
英文摘要:
      In this study, the basic processing properties and nutrient ingredients of fruit peel, pulp juice, seeds and core were investigated for Xianghei-0701, a variety of Kadsura coccinea cultivated in the southwest part of Hunan Province. The results showed that the peel occupied the largest proportion(42.48%-47.70%) in the whole aggregate fruit with low juice yield. The pulp juice(35.01%-37.47%) was turbid with the lowest value of L*, a* and b* and had the highest contents of total sugar(5.27%) and reducing sugar(2.34%). The seed(7.65%-11.16%) had thick seed shells with obvious bitterness, and had the highest contents of ash(7.20%), protein(11.14%) and fat(21.70%). The proportion of fruit core was 8.21%-11.21%. In fruit peel, pulp juice, seeds and core, the content of potassium was the highest of the tested minerals, reaching 3 952.17, 2 064.10, 4 900.43 and 2 937.40 mg/kg, respectively. The content of choline was the highest of the tested vitamins with 590.33, 621.67, 692.33 and 248.33 mg/100g, respectively. In conclusion, K. coccinea fruit can be used for developing different types of health products since remarkable differences existed in processing characteristics and main nutrients among different parts of it.
