The composition of kiwifruit is important for understanding the nutritional value of kiwifruit for consumption. Our aim was to develop a reference nutritional composition profile for a gold-fleshed kiwifruit Zespri® SunGold Kiwifruit and a green-fleshed kiwifruit Zespri® Sweet Green Kiwifruit. Ten representative single-replicate (10 growers) samples, each containing 40 fruit, were prepared for both kiwifruit varieties. Samples were analysed for macronutrients, minerals, and vitamins. The analytical results reveal that the nutrient composition of SunGold and Sweet Green are largely similar to other commercially available kiwifruits. However, a key difference is the elevated levels of vitamin C in SunGold (161mg/100g edible flesh) and Sweet Green, (150mg/100g), compared to 85mg/100g commonly found for the green 'Hayward' variety. Levels of dietary fibre, potassium, vitamin E, and folate are similar to other commercial kiwifruit Zespri® Gold Kiwifruit ('Hort16A') and Green Kiwifruit ('Hayward'), confirming kiwifruit as a good source of these nutrients.
了解奇异果的营养成分对于理解其食用营养价值至关重要。我们的目标是为金果肉奇异果佳沛®阳光金果和绿果肉奇异果佳沛®甜蜜绿奇异果制定一份参考营养成分概况。为这两个奇异果品种各准备了10个具有代表性的单重复样本（来自10位种植者），每个样本包含40个果实。对样本进行了常量营养素、矿物质和维生素分析。分析结果表明，阳光金果和甜蜜绿奇异果的营养成分与其他市售奇异果大致相似。然而，一个关键差异在于，阳光金果（每100克可食果肉含161毫克）和甜蜜绿奇异果（每100克含150毫克）中的维生素C含量高于绿色的“海沃德”品种常见的每100克85毫克。膳食纤维、钾、维生素E和叶酸的含量与其他市售奇异果佳沛®金奇异果（“Hort16A”）和绿奇异果（“海沃德”）相似，证实奇异果是这些营养素的良好来源。
