In vitro chemical properties and antioxidant potential and in vivo mutagenic activity of honey-sweetened cashew apple nectar (HSCAN), a beverage produced from the cashew pseudo-fruit (Anacardium occidentale L.) and of its constituents were assessed. Analytical procedures were carried out to investigate the honey used in the HSCAN preparation, and the results observed are in accordance with Brazilian legal regulations, except for diastase number. HSCAN and pulp were investigated for ascorbic acid, carotenoid, anthocyanin and total phenolic contents, and both showed high acid ascorbic concentrations. Antioxidant capacity using 2,2-diphenyl-1-picrylhydrazyl radical (DPPH) and/or β-carotene/linoleic acid systems were applied and demonstrated a weak antioxidant capacity of honey and HSCAN, but cashew apple pulp demonstrated high antioxidant capacity. A weakly positive mutagenic effect of cashew pulp 20% was observed using the somatic mutation and recombination test (SMART) in Drosophila melanogaster only in the high-bioactivation (HB) cross. On the contrary, HSCAN was not mutagenic in both standard and high bioactivation crosses. HSCAN exhibited slight antioxidant activity, which could be associated with the high amount of ascorbic acid found in the samples evaluated. The beverage prepared did not induce DNA damage in somatic cells of D. melanogaster, which means that it is neither mutagenic nor recombinagenic in this test system.

评估了用腰果假果 (Anacardium occidentale L.) 生产的饮料蜂蜜甜味腰果苹果花蜜 (HSCAN) 的体外化学特性,抗氧化潜力和体内诱变活性及其成分。进行了分析程序以调查HSCAN制剂中使用的蜂蜜,观察到的结果符合巴西法律法规,但淀粉酶编号除外。研究了HSCAN和纸浆中的抗坏血酸,类胡萝卜素,花青素和总酚含量,两者均显示出较高的抗坏血酸浓度。使用2,2-二苯基-1-微肼基自由基 (DPPH) 和/或 β-胡萝卜素/亚油酸体系进行了抗氧化能力,表明蜂蜜和HSCAN的抗氧化能力较弱,但腰果苹果浆具有较高的抗氧化能力。仅在高生物活化 (HB) 杂交中,使用果蝇的体细胞突变和重组试验 (SMART) 观察到腰果果肉20% 的弱阳性诱变作用。相反,HSCAN在标准和高生物活化杂交中均没有诱变。HSCAN表现出轻微的抗氧化活性,这可能与评估样品中发现的大量抗坏血酸有关。制备的饮料不会诱导黑腹大白鼠体细胞的DNA损伤,这意味着它在该测试系统中既没有诱变性也没有重组性。
