Thirty-seven apricot varieties, including four new releases (Rojo Pasión, Murciana, Selene, and Dorada) obtained from different crosses between apricot varieties and three traditional Spanish cultivars (Currot, Mauricio, and Búlida), were separated according to flesh color into four groups. The L*, a*, b*, hue angle, and chroma color measurements on the skin and flesh as well as other quality indices including flesh firmness, soluble solids, titratable acidity, and pH were plotted against the total carotenoid content measured by HPLC. Among the 37 apricot varieties, the total carotenoid content ranged from 1,512 to 16,500 microg 100 g(-1) of edible portion, with beta-carotene as the main pigment followed by beta-cryptoxanthin and gamma-carotene. The wide range of variability in the provitamin A content in the apricot varieties encouraged these studies in order to select the breeding types with enhanced carotenoid levels as the varieties with a higher potential health benefit. The carotenoid content was correlated with the color measurements, and the hue angle in both flesh and peel was the parameter with the best correlation (R = 0.92 and 0.84, respectively). An estimation of the carotenoid content in apricots could be achieved by using a portable colorimeter, as a simple and easy method for field usage applications.
37个杏品种,包括通过杏品种间不同杂交获得的4个新品种(罗霍·帕西翁、穆尔西亚纳、塞勒涅和多拉达)以及3个西班牙传统品种(库罗特、毛里西奥和布利达),根据果肉颜色分为4组。将果皮和果肉的L*、a*、b*、色相角和色度颜色测量值以及包括果肉硬度、可溶性固形物、可滴定酸度和pH值在内的其他品质指标,与通过高效液相色谱法测定的总类胡萝卜素含量进行绘图。在这37个杏品种中,可食部分的总类胡萝卜素含量在1512至16500微克/100克之间,以β-胡萝卜素为主要色素,其次是β-隐黄质和γ-胡萝卜素。杏品种中维生素A原含量的广泛变异性促使开展这些研究,以便选择类胡萝卜素水平更高、具有更大潜在健康益处的品种作为育种类型。类胡萝卜素含量与颜色测量值相关,果肉和果皮中的色相角是相关性最好的参数(分别为R = 0.92和0.84)。使用便携式色度计可以估算杏中的类胡萝卜素含量,这是一种简单易行的田间应用方法。
