摘要：

为确定橄榄果实留树保鲜最佳时间，判断橄榄果实留树保鲜技术的可行性，以‘锡1号’橄榄正季果（11月采摘）和留树保鲜果（12月采摘、1月采摘、4月采摘）为试验材料，采用微量法测定样品中的氨基酸（半胱氨酸、谷氨酸、赖氨酸、脯氨酸和羟脯氨酸）、营养成分（单宁、抗坏血酸、纤维素、水溶性果胶、总糖、蔗糖和还原糖）、功能性成分（原花青素、类黄酮、总酚和总抗氧能力）和酶活性（酸性磷酸酶，碱性磷酸酶、羧酸酯酶、过氧化物酶、过氧化氢酶、多酚氧化酶、乙酰胆碱酯酶和超氧化物歧化酶）共24个指标。‘锡1号’橄榄留树保鲜1个月与正季采摘相比，24个指标均无显著差异(P>0.05)；留树保鲜2个月，半胱氨酸、单宁、纤维素、原花青素、类黄酮、总抗氧能力、酸性磷酸酶、羧酸酯酶和过氧化物酶的含量均显著下降(P<0.05)，而抗坏血酸和水溶性果胶的含量却显著上升(P<0.05)，其他指标变化不显著；留树保鲜5个月，抗坏血酸、水溶性果胶、碱性磷酸酶和超氧化物歧化酶的含量均显著上升(P<0.05)，除脯氨酸外19个指标均呈显著下降趋势。‘锡1号’橄榄果实可留树保鲜1个月，其果实品质与正季采收无明显差异。

Abstract:

The paper aims to determine the optimal time for Canarium album to stay fresh, and to evaluate the feasibility of olive fruit tree preservation technology. Using ‘Xi No.1’ olive fruit in the season (harvested in November) and preserved fruit (picked in December, January, and April) as test materials, a total of 24 indicators of amino acids (cysteine, glutamic acid, lysine, proline and hydroxyproline), nutritional components (tannins, ascorbic acid, cellulose, water-soluble pectin, total sugar, sucrose and reducing sugars), functional components (proantho cyanidins, flavonoids, total phenols and total antioxidant capacity) and enzyme activity (acid phosphatase, alkaline phosphatase, carboxylates, peroxidases, catalases, polyphenol oxidases, acetylcholinesterase and superoxide dismutase) in the samples were determined by micro method. There were no significant difference in 24 indexes of ‘Xi No.1’ olive preserved for one month compared with that of picked in normal season (P>0.05). After two months of storage, the contents of cysteine, tannin, cellulose, proantho cyanidins, flavonoids, total antioxidant capacity, acid phosphatase, carboxylesterase, and peroxidase were significantly decreased (P<0.05), while the contents of ascorbic acid and water-soluble pectin were significantly increased (P<0.05), and other indexes had no significant changes. The contents of ascorbic acid, water-soluble pectin, alkaline phosphatase, and superoxide dismutase were significantly increased (P<0.05) after 5 months of tree preservation, while 19 indexes except proline were significantly decreased. The Canarium album of ‘Xi No.1’ can be kept fresh on tree for one month, and its fruit quality is not significantly different from that harvested in normal season.
