消费者对桃子和油桃达到较高接受度所需的最低 RSSC 是通过使用低 RTA 和高 RTA 融化果肉品种的“店内”消费者测试来确定的，作为我们制定最低质量指数计划的一部分。对于低酸白肉桃“Ivory Princess”、低酸黄肉桃“Honey Kist”、高酸黄肉桃“Elegant Lady”和高酸黄肉桃“Spring Bright”来说，喜爱程度和消费者接受度与成熟可溶性固形物浓度（RSSC）相关，而与成熟可滴定酸度（RTA）无关。对于测试的两个高酸（0.70-0.90% RTA）品种，消费者接受度随着 RSSC 的增加而迅速增加，达到相似的 90%。在这些品种中，消费者的接受度达到了一个稳定水平，超过这个水平，消费者对 RSSC 的任何额外增加都变得不敏感。 “Elegant Lady”和“Spring Bright”的 RSSC 分别达到了 11-12% 和 10-11% 的稳定水平，消费者接受度接近 90%。对于低酸品种（0.30-0.50% RTA）、“Ivory Princess”和“Honey Kist”，消费者接受度随着 RSSC 的增加而逐渐增加，但未达到平台期，并且达到接近 100% 的接受度，RSSC 分别为 16% 和 15%。 对于这些低酸和高酸品种，消费者接受度与 RSSC 密切相关，但根据 RSCC 水平的不同，消费者接受度在不同的 RSCC 水平上达到了最大。品种。这些品种以不同的 RSSC 水平获得了消费者的高度认可，这一事实表明单一通用 RSSC 质量指数无法可靠地确保所有品种的消费者满意度。 (c) 2005 Elsevier B.V. 保留所有权利。
The minimum RSSC needed to reach high consumer acceptance for peach and nectarine was determined by using 'in-store' consumer tests of low and high RTA melting flesh cultivars as a part of our program to develop minimum quality indexes. For 'Ivory Princess', a low acid, white flesh peach, 'Honey Kist', a low acid, yellow flesh nectarine, 'Elegant Lady', a high acid, yellow flesh peach, and 'Spring Bright', a high acid, yellow flesh nectarine, degree of liking and consumer acceptance were associated with ripe soluble solids concentration (RSSC) regardless of ripe titratable acidity (RTA). For the two high acid (0.70-0.90% RTA) cultivars tested, Consumer acceptance increased rapidly as RSSC increased, reaching similar to 90%. In these cultivars, consumer acceptance reached a plateau and above which, it became insensitive to any additional increase in RSSC. For 'Elegant Lady' and 'Spring Bright', the plateau was reached at 11-12%, and 10-11% RSSC with similar to 90% consumer acceptance, respectively. For the low acid cultivars (0.30-0.50% RTA), 'Ivory Princess' and 'Honey Kist', consumer acceptance progressively increased as RSSC increased without reaching a plateau, and attained nearly 100% acceptance with RSSC of 16 and 15%, respectively.For these low acid and high acid cultivars, consumer acceptance was closely related to RSSC but maximum consumer acceptance was attained at different RSCC levels depending on the cultivar. The fact that these cultivars reached high consumer acceptance with different RSSC levels indicates that a single generic RSSC quality index would not be reliable to assure consumer satisfaction across all cultivars.
