Abstract

Turiaçu is a traditional pineapple cultivar in the state of Maranhão, Brazil, and its fruits have high potential for the fresh fruit market due to consumer acceptance. This cultivar is in the process of domestication, but information on the quality of its fruits and their standards for marketing is scarce. The objective of this study was to evaluate the biometric and chemical characteristics of the Turiaçu pineapple cultivar and the Pérola cultivar, which are grown in the main pineapple producing areas—Turiaçu, and São Domingos do Maranhão—in the state of Maranhão. The fruits were harvested at the green stage to evaluate the following biometric characteristics: fruit weight, infructescence weight, pulp yield, crown, peel and total residues, and base to apex diameter ratio; and the following chemical characteristics—total soluble solids (TSS), total titratable acidity (TTA), and TSS to TTA chemical ratio. The Turiaçu cultivar presented higher fruit and infructescence weights, more cylindrical fruits, and pulp with higher TSS concentration and less acidity, compared to the Pérola cultivar. Fruits of the Turiaçu cultivar had more desirable biometric and chemical qualities for the consumer market— they were large, cylindrical, sweet, and with low acidity—, compared to those of the Pérola cultivar.
一种传统的菠萝品种(turiau)与巴西最流行的品种(p罗拉)的果实质量比较
turiau是巴西maranh州的一种传统菠萝品种,由于消费者的接受,它的果实在新鲜水果市场上具有很高的潜力。该品种正处于驯化过程中,但有关其果实质量和销售标准的信息很少。本研究的目的是评价种植在主要菠萝产区——图里亚帕拉苏和多明戈斯·马拉尼赫 o - maranh o -的图里亚帕拉苏菠萝品种和p罗拉品种的生物特征和化学特性。在青期采收果实,评价其生物特征:果实重量、果序重量、果肉产量、树冠、果皮和总残量、基部与先端直径比;以及以下化学特性——总可溶性固形物(TSS)、总可滴定酸度(TTA)和TSS / TTA化学比。结果表明,与p罗拉品种相比,图里亚帕鲁品种的果实和果核质量更高,果实呈圆柱形,果肉TSS浓度更高,酸度更低。对于消费市场来说,turia品种的果实具有更理想的生物特征和化学品质——它们大,圆柱形,甜,低酸度——与p品种相比。
