| 摘 要： | 为比较分析广东省主要鲜食橄榄果实质构特性的差异,探讨鲜食橄榄果实质地评价的量化参数,验证感官评价质地的有效性。采用质构刺穿试验法对7个优质鲜食橄榄品种果肉质构参数和2种水肥管理方式不同成熟期的‘香甜榄’果实品质进行测定和比较分析。结果表明,不同品种之间果肉的各质构参数变异系数为12.57%~23.95%,差异性显著,与感官评价一致;果皮强度与果皮脆性和果皮韧性均呈显著正相关,果皮破裂深度与果肉硬度呈显著负相关。采用本次试验栽培管理方式可以提高橄榄完熟果实可溶性固形物6%、可滴定酸3.5%、单宁54.9%、果皮强度12.7%、果皮脆性23.5%,降低粗纤维10%、果皮韧性13.7%。果实质地品质参数主成分分析表明,果皮强度、果实硬度和纤维指数可作为质地参数量化区分不同品种间的差别,并明确果皮强度、果实硬度分别小于2300、1600 g和纤维指数大于10,为鲜食橄榄果肉质地品质较好的数值范围。研究初步建立了利用质构刺穿试验法量化评价鲜食橄榄果实质地品质的方法。

| Abstract: | To analyze the differences of fruit texture quality of fresh Canarium album in Guangdong Province, the quantitative parameters of texture evaluation of fresh C. album fruits were investigated to verify the validity of sensory evaluation of texture. The texture puncture test was used to measure the texture parameters of seven varieties of fresh C. album fruits, and the effects of different water and fertilizer management on the fruit quality of C. album ‘Xiangtianlan’ were evaluated. Results showed that the texture parameters of fruits among different varieties were significantly different, with a variation coefficient of 12.57%-23.95%, which was consistent with the sensory evaluation. The correlation analysis results showed that the pericarp strength was positively correlated with pericarp brittleness and toughness, while pericarp breaking depth was significantly and negatively correlated with pulp hardness. Under the water and fertilizer management in this study, the soluble solid content, titrable acid content, tannin content, pericarp strength and pericarp fragility increased by 6%, 3.5%, 54.9%, 12.7% and 23.5%, respectively, while the crude fiber content and pericarp toughness decreased by 10% and 13.7%, respectively. Principal component analysis of fruit texture and quality parameters showed that pericarp strength, pulp hardness and fiber index could be used as texture parameters to quantitatively distinguish the differences among different fresh C. album varieties, and the numerical ranges of texture in fresh C. album fruits with good quality were: the pericarp strength and fruit hardness were less than 2300 and 1600 g, respectively, and the fiber index was greater than 10. In this study, a method for detecting the texture quality of fresh C. album fruits was preliminarily established by whole fruit texture puncture test. |
