Abstract

ABSTRACT Macaúba (Acrocomia aculeata) is an oleaginous plant for use in biodiesel production. After harvest, the fruits of this palm tree have high water content, thus attracting microorganisms. Therefore, it is necessary to adopt appropriate fruit storage strategies to ensure oil quality. The objective of this study was to evaluate the effect of the combined use of drying and ozonation on the quality of macaúba fruit oil used to produce biodiesel. The fruits were dried at 60 °C and subsequently subjected to ozonation (treatments with different dosages and application intervals). The treatments with the combined use of drying and ozonation were efficient in maintaining FFA content below 5% for up to 45 days of storage. Furthermore, these treatments did not affect the oil content in the mesocarp of macauba fruits during 180 days of storage. Thus, the combined technique of drying and ozonation of macauba fruits without epicarps can become a viable alternative post-harvest.

采用干燥和臭氧氧化相结合的方法保存澳门果实，用于生产生物柴油

Macaúba (Acrocomia aculeata)是一种产油植物，用于生产生物柴油。收获后，这棵棕榈树的果实含水量高，从而吸引微生物。因此，有必要采取适当的果品贮藏策略，以保证油质。本研究的目的是评价干燥和臭氧氧化联合使用对用于生产生物柴油的macaúba果油质量的影响。果实在60°C下干燥，随后进行臭氧化(不同剂量和施用时间间隔的处理)。干燥和臭氧化联合处理可有效地将游离脂肪酸含量维持在5%以下，最长可达45天。此外，这些处理对贮藏180天的澳门果实中果皮油脂含量没有影响。因此，对没有外皮的澳门巴果实进行干燥和臭氧化处理的结合技术可以成为一种可行的采收后替代方法。
