Anacardium occidentale, more commonly known as cashew tree, is a tropical tree native from South America. The industrial use of the cashew is basically aimed at the processing of the nut and, minor extent, the use of the peduncle, generating high losses due to the large quantity of cashew apple bagasse that are discarded. Another cashew’s tree reject is the exudate, a yellowish-colored resin obtained by natural exudation or by incisions made on the stem of the cashew, which serves as raw material for the cashew gum production. In this context, the present work carries out a technological prospection in databases of patents and scientific articles mapping the cashew’s rejects applications, such as cashew apple bagasse and cashew gum as a byproduct. After the analysis of patents and scientific articles, it was possible to perceive that cashew apple bagasse presents a good potential, as an abundant and low-cost source of bioactive compounds, being an excellent raw material for functional food composition. In particular, many studies involving the cashew gum are in the area of medicine. Thus, the present study mapped the potentiality of the cashew rejects that can add environmental and social dimensions that are often overlooked in the context of small-scale agricultural production.

Statement of novelty

This work identified the potential in agroindustrial cashew rejects in order to develop new sustainable perspectives for its use. Sustainable alternatives were also identified in the cashew production chain and new applications for the use of cashew apple bagasse and cashew exudate.

西洋参，通常被称为腰果树，是一种来自南美的热带树。腰果的工业用途基本上是针对坚果的加工，而在较小程度上是指柄的用途，由于丢弃了大量的腰果苹果蔗渣，因此产生了很高的损失。腰果的另一种树渣是渗出液，一种淡黄色的树脂，是通过自然渗出或通过在腰果茎上切开的切口获得的，用作腰果胶生产的原料。在这种情况下，本工作在专利和科学文献数据库中进行了技术展望，映射了腰果渣申请，例如腰果苹果渣，腰果胶等副产品。经过对专利和科学论文的分析，可以看出，腰果苹果蔗渣具有很好的潜力，它是生物活性化合物的丰富而低成本的来源，是功能性食品组合物的极佳原料。特别地，涉及腰果胶的许多研究都在医学领域。因此，本研究绘制了腰果渣的潜力，这些果渣可以增加环境和社会方面的影响，而在小规模农业生产的背景下，这些方面常常被忽视。

新奇声明

这项工作确定了农用工业腰果废弃物的潜力，以便为其使用开发新的可持续性观点。在腰果生产链中，以及在使用腰果苹果蔗渣和腰果渗出液的新应用中，也确定了可持续的替代方法。
