Objective To study the nutritional components of Weiying watermelon foranalyze and evaluate the nutritional quality of Weiying watermelon. Methods Namely “Meidu” watermelon from 2 main production areas of Weiying watermelon (S1 and S2) were used as experimental materials, and the same variety of watermelon from two other production areas (S3 and S4) as controls. The content of sugar, organic acid, amino acid, mineral, soluble solid, β-carotene, lycopene and vitamin C in the watermelons from the 4 production areas were detected and analyzed. Results The watermelon from different producing areas exhibited certain variations in quality characteristics. The sugar components in watermelon was mainly glucose and fructose, organic acids was mainly malic acid and lemon, free amino acids was mainly citrulline, and it also contains abundant mineral elements; the glucose content, sugar-acid ratio and sweetness-sourness ratio in S1 and S2 were higher than those in S3 and S4, while the total acid content was the opposite. In addition, the levels of the citrulline, β-carotene, lycopene and vitamin C in S1 and S2 were also higher than those in S3 and S4, respectively. The comprehensive performance of the nutritional quality of S1 and S2 were superior to that of S3 and S4 based on the principal component analysis. Conclusion Weiying watermelon has better flavor and texture, richer nutritional components, and superior nutritional quality.

目的 分析评价魏营西瓜营养品质, 探究魏营西瓜的营养成分。方法 以魏营2个西瓜主产地的“美都”西瓜为研究对象(S1和S2), 以其他2个产地的同品种西瓜为对照(S3和S4), 检测分析4个产地西瓜中的糖、有机酸、氨基酸、矿物质元素、可溶性固形物、β-胡萝卜素、番茄红素和维生素C等营养指标。结果 不同产地西瓜营养品质存在一定差异性, 西瓜中糖组分以葡萄糖和果糖为主、有机酸以苹果酸和柠檬为主、游离氨基酸以瓜氨酸为主, 并含丰富矿物质元素; S1和S2的葡萄糖含量、糖酸比和甜酸比均高于S3和S4, 总酸含量则相反; S1和S2的瓜氨酸、β-胡萝卜素、番茄红素和维生素C的含量也均分别高于S3和S4; 基于主成分分析, S1和S2营养品质综合表现均优于S3和S4。结论 魏营西瓜具有更好的风味口感, 更丰富的营养成分, 营养品质更佳。

魏营镇位于宿迁市泗洪县西南岗, 地处淮河流域, 地形以岗地坡地为主, 且四季分明, 昼夜温差大, 其土壤为黑淤土、岗潮土等, 腐殖质含量高, 土质肥沃, 透气性较好, 钾、铁等元素含量丰富[1]。该镇种植西瓜(Citrullus lanatus L.)的历史已有50余年, 良好的水土、温光资源等自然条件为西瓜养分吸收提供了得天独厚的条件, 有利于西瓜高品质的形成, 魏营西瓜已成为当地特色优势产业。2020年, 魏营西瓜获批为国家农产品地理标志登记保护产品(证书号: AGI02836), 其具有肉质酥脆细腻、籽少、汁多、味甜、爽口等特征。目前, 当地政府正在大力发展魏营西瓜产业, 积极打造魏营西瓜品牌。因此, 对魏营西瓜营养品质进行研究具有重要的意义。
西瓜是一年生蔓生藤本, 属于葫芦科, 是世界5大水果之一, 生产规模仅次于葡萄、香蕉、柑橘和苹果[2-3]。西瓜的品质包括商品品质和营养品质[4]。商品品质即外观品相, 是指果实大小、形状、果肉颜色、果皮颜色条纹、果皮厚度等外观特征; 营养品质则是西瓜内在营养成分, 包括总糖、可溶性固形物、膳食纤维等, 决定果实的风味[5-7]。根据相关文献报道, 由于土壤、气候等环境差异, 西瓜在各地方种植的营养品质、风味口感均有差异。高歌等[8]研究发现东台西瓜营养品质优于其他产区西瓜, 梁朴等[9]研究了宁夏不同地区的麒麟西瓜, 得出不同地区西瓜品质有差异, 唐桃霞等[10]发现靖远地区不同乡镇旱砂西瓜产品品质也存在差异。目前, 关于魏营西瓜营养品质的研究极少, 仅局限于检测维生素C和可溶性固形物等常规营养品质指标, 未见全面的营养品质评价分析的报道。本研究以魏营镇种植规模最大, 能代表魏营西瓜的品种‘美都’为研究对象, 选取魏营镇2个主产基地—欧岗村和刘营村的美都西瓜进行营养成分检测分析, 以紧邻魏营镇的上塘镇及南京江宁区横溪街道的美都西瓜为对照, 分析评价魏营西瓜的营养品质, 以期为魏营西瓜品质提升、品牌打造、产业升级提供理论支撑。

可溶性膳食纤维含量参照GB/T 22224—2008《食品中膳食纤维的测定 酶重量法和酶重量法-液相色谱法》测定。
甜度值参照张素敏等[11]的方法, 即甜度=蔗糖×1+果糖×1.75+葡萄糖×0.75; 糖酸比=可溶性固形物/总酸; 甜酸比=甜度/总酸。
集样品重复测定3次, 试验数据结果用平均值±标准偏差表示。数据采用Excel 2003进行处理, 运用SPSS 20.0分析软件对数据进行主成分分析和最小显著差别(least significant difference, LSD)检验, 设置P<0.05为显著性差异。
根据表1可知, 不同产地西瓜中蔗糖、葡萄糖和果糖含量均有差异, 葡萄糖和果糖含量分别在29.17~ 40.89 mg/g之间和36.59~42.59 mg/g之间, 均高于蔗糖含量(18.12~24.23 mg/g)。其中, S1和S2的葡萄糖含量分别达到40.05 mg/g和40.89 mg/g, 均分别高于S3和S4, 显著高于S3的29.17 mg/g (P<0.05), 而S1的蔗糖和果糖含量(18.12 mg/g和36.59 mg/g)则均略低于其他3个产地。相比之下, 整体上S2在糖分积累方面表现更佳, 蔗糖、葡萄糖和果糖的总含量达到107.56 mg/g, 显著高于其他3个产地(P<0.05)。
根据表2可知, 不同产地西瓜中有机酸主要包括苹果酸、丙二酸、柠檬酸、富马酸和琥珀酸, 其中苹果酸是构成有机酸的主要成分, 介于318.44~408.49 mg/100 g之间, 占比80.70%~84.21%, 其次是柠檬酸, 介于65.90~68.21 mg/100 g之间, 占比14.02%~17.28%, 其余几种有机酸含量较低。S1的苹果酸和S2的柠檬酸含量最高, 分别为408.49 mg/100 g和68.21 mg/100 g。另外, S1的琥珀酸含量最高, 显著高于其他3个产地(P<0.05), S1和S2的丙二酸、柠檬酸和富马酸含量均分别高于S3和S4。相比之下, 整体上S1有机酸积累更丰富, 其总含量为485.64 mg/100 g, 高于其他3个产地。
不同产地西瓜糖酸比和甜酸比如表3所示。不同产地西瓜的可溶性固形物含量在11.31%~13.10%之间, 总酸含量在0.11%~0.15%之间, 其中, 可溶性固形物含量依次为S2>S3>S1>S4, 总酸含量依次为S2<S1<S4<S3, 且S1和S2的总酸均分别显著低于S3和S4 (P<0.05)。另外, 糖酸比和甜酸比是重要的口感指标, 不同产地西瓜糖酸比在80.96~122.12之间, 依次为S2>S1>S3>S4; 甜酸比在77.05~119.77之间, 依次为S2>S1>S4>S3。因此, 可以得知, S1和S2的在口感表现均比S3和S4更好, 尤其是S2。
根据表4可知, 不同产地西瓜中均含有多种游离氨基酸, 且以瓜氨酸为主, 其含量在1.61~2.49 g/kg之间, 占比51.51%~56.33%。其中, S1和S2的瓜氨酸含量分别为2.31 g/kg和2.49 g/kg, 均分别高于S3和S4 (2.21 g/kg和1.61 g/kg), 尤其是S2的瓜氨酸含量显著高于S4 (P<0.05)。另外, 苯丙氨酸、亮氨酸、异亮氨酸、精氨酸、色氨酸、谷氨酰胺和天冬氨酸含量相对较低, 在0.10~0.50 g/kg之间; 所测游离氨基酸的总量在2.99~4.42 g/kg之间, 依次为S1=S2>S3>S4, 可见魏营西瓜主产区西瓜中游离氨基酸含量比其他2个产地更高。
西瓜矿物质元素含量检测结果如表5所示。不同产地西瓜中含有丰富的矿物质元素, 且钾、镁、磷和钙元素含量较高, 分别在434.12~493.10 mg/kg、91.01~149.16 mg/kg、84.23~109.41 mg/kg和42.21~73.10 mg/kg之间。S1的锌、钙、钾和磷元素含量最高, 且锌、钙和钾含量显著高于其他3个产地(P<0.05); S2除钠元素含量显著高于其他3个产地外, 其他元素含量较低; S3的铜、铁、镁和锰元素含量最高, 钾和钠元素最低; S4的铜和锰元素含量最低。由此可见, 不同产地西瓜矿物质元素含量有一定差异。
表6可知, 不同产地西瓜含水量差异小, 在90.01%~91.65%之间, S1和S2的β-胡萝卜素(分别为5.83 μg/g和2.53 μg/g)、番茄红素(分别为4.29 μg/g和2.09 μg/g)和维生素C含量(分别为5.88 mg/100 g和5.91 mg/100 g) 均分别高于S3和S4, 尤其S1的β-胡萝卜素和番茄红素含量显著高于其他3个产地(P<0.05)。同时, 蛋白质和可溶性膳食纤维含量分别介于0.72~0.91 g/100g和2.25%~3.57%之间, 并且S4蛋白质和S3可溶性膳食纤维含量最高。由此可见, 不同产地西瓜中上述营养成分方面具有一定差异性。
通过对不同产地西瓜营养品质指标进行主成分分析, 由表7表8可知, 前4个主成分的累计方差贡献率为85.694%。第1个主成分的特征值为10.157, 方差贡献率为29.019%, 葡萄糖、糖酸比、甜酸比、镁、锰、磷、维生素C、蛋白质和可溶性膳食纤维含量的载荷均在0.70以上; 第2个主成分方差贡献率为24.673%, 决定其大小的指标主要是蔗糖、苯丙氨酸、亮氨酸、色氨酸、钙、铜和钾; 第3个主成分方差贡献率为18.895%, 总酸、可溶性固形物、谷氨酰胺和瓜氨酸的载荷较大; 第4个主成分方差贡献率为13.106%, 载荷较大的指标为苹果酸含量。
根据前4个主成分的累计贡献率超过85%, 以前4个主成分建立不同产地西瓜营养品质指标的比较综合模型。以各个主成分的特征值和载荷值计算特征向量, 得到表达式:

据现有文献报道, 西瓜果实成熟时糖组分主要为果糖和葡萄糖[12-13], 这与本研究得出不同产地西瓜糖组分中的葡萄糖和果糖占比较大结论是一致的, 但也有研究发现有些品种西瓜果实成熟时糖组分以蔗糖为主[14], 这可能是西瓜果实糖分的积累除了自身遗传因素外, 同时受到产地环境影响较大。杨玉梅等[15]研究发现昼夜温度与可溶性糖含量呈正比关系, S1和S2的葡萄糖含量分别高于S3和S4, 总酸则反之, 这可能说明与魏营地区当地昼夜温差大等气候条件确实有利于西瓜糖分的积累。
可溶性固形物是果蔬中糖类以及各种可溶于水的其他物质的总称[16]。由可溶性固形物、总酸和可溶性糖得到的糖酸比、甜酸比是影响西瓜风味的重要因素, 是水果特征口味指标, 直接影响水果口感[17-20]。本研究结果显示, S2的可溶性固形物含量最高, S1的略低于S3, 但是S1和S2的糖酸比、甜酸比均高于S3和S4, 表明S1和S2在口感上表现更佳。有机酸是决定水果风味的重要成分[21], DUNE等[22], 刘景安[23], GAO等[24]研究表明西瓜成熟果实中有机酸主要为苹果酸, 其次是柠檬酸, 与本研究结论一致, 这可能和西瓜自身特性有关, 但是可能因不同产地的环境、种植技术、管理模式等导致其有机酸含量有一定的差异性。
游离氨基酸作为植物体内重要的组分之一, 在植物生长发育过程中发挥着重大作用[25], 可通过多种代谢途径形成有机酸、糖类、香气物质等风味营养物质[26]。有研究表明, 瓜氨酸、亮氨酸、精氨酸、色氨酸、谷氨酰胺和天冬氨酸对人体都有很高的营养价值, 比如瓜氨酸具有保护心肺, 增强免疫力作用, 谷氨酰胺是人体中含量最丰富的循环性氨基酸, 是免疫细胞基因表达的重要组成部分[27]。本研究对西瓜中游离氨基酸进行分析, 结果表明, 不同产地西瓜游离氨基酸中瓜氨酸含量最高, 占总游离氨基酸的51.51%~56.33%, 这与万学闪等[28]、杨东东等[29]研究得出的西瓜果实氨基酸中是瓜氨酸含量最高的结论一致; 同时, S1和S2的瓜氨酸、β-胡萝卜素、番茄红素和维生素C含量均比S3和S4高, 这在某种程度上表明魏营西瓜营养品质相比其他2产地西瓜更佳, 可能受不同产地环境的土壤、气候等因素的影响较大, 与产地环境的具体关联性有待进一步研究。
矿物质元素是构成有机体组织的重要物质, 人体必须每天摄入一定量矿物质营养来维持身体的正常需要。西瓜矿物质含量和产地土壤条件密切相关, 钾肥用量、土壤有效钾含量均影响西瓜矿物质元素[30-31]。本研究结果显示, 西瓜中含量丰富的矿物质元素, 包括锌、钙、铜、铁、钾、镁、锰、钠、磷, 不同产地西瓜的矿物质元素含量有一定差异。相比其他3个产地, S1的锌、钙、钾和磷元素含量最高, 可能与该产地施肥管理及土壤环境关系较大。
单一的营养指标很难去全面评价西瓜的营养品质。主成分分析能够用少量综合指标代替原来多个指标的大部分信息, 可以在不损失或者较少损失原有信息的情况下对指标进行综合评价。本研究应用主成分分析的方法以累计贡献率大于85%的4个主成分对4个不同产地西瓜的营养指标进行综合评价, 结果表明, S1和S2的营养品质优于S3和S4, 说明魏营主产地的西瓜营养成分含量的综合表现较其他2产地更高, 营养品质更优。
不同产地西瓜中的糖、有机酸、氨基酸、矿物质、蛋白质、维生素C、可溶性固形物、可溶性膳食纤维、番茄红素等含量存在一定差异。西瓜中糖组分以葡萄糖和果糖为主、有机酸以苹果酸和柠檬为主、游离氨基酸中以瓜氨酸为主, 并含丰富矿物质元素。S1的葡萄糖、瓜氨酸、β-胡萝卜素、番茄红素和维生素C含量分别为40.05 mg/g、2.31 g/kg、5.83 μg/g、4.29 μg/g和5.88 mg/100 g, S2的分别为40.89 mg/g、2.49 g/kg、2.53 μg/g、2.09 μg/g和5.91 mg/100 g, 分别均高于S3和S4; 糖酸比依次为S2>S1>S3>S4, 甜酸比S2>S1>S4>S3; 营养品质综合评价得分为S2>S1>S3>S4。因此, 魏营西瓜相比其他2产地的具有更好的风味口感和营养品质表现。
