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3952.17、2064.10、4900.43、2937.40 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。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 3952.17,2064.10,4900.43 and 2937.40 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.
