Abstract

Cashew apple is a source of by-products in the cashew industry. Powder products provide convenience to the process of use, transport, and preservation of nutrients. In this study, the production of soluble powder from cashew apples was developed through the investigation of hydrolysis process (time, temperature, and enzyme tannase) and convective drying conditions (temperature and maltodextrin content). The following indicators are evaluated, such as the total polyphenol content (TPC), total tannin content, total ascorbic acid, solubility, turbidity, and color. The results have shown that TPC increased by 1.67 times, and more than 50% of tannins was removed after the hydrolysis process. At the same time, the efficiency of the process over 30% under all processing conditions was evaluated. These results are the foundation for the development of cashew apple powder and related products, thereby improving the economy of the cashew industry in Vietnam and the world.

评估腰果苹果粉在水解和对流热风干燥过程中的多酚和抗坏血酸含量、单宁去除能力以及物理性质

腰果苹果是腰果产业副产品的一种来源。粉末产品为使用、运输和营养保存过程提供了便利。本研究通过对水解过程（时间、温度和单宁酶）和对流干燥条件（温度和麦芽糊精含量）的研究，开发了腰果苹果可溶性粉末的生产方法。评估指标包括总多酚含量（TPC）、总单宁含量、总抗坏血酸、溶解度、浑浊度和颜色。结果表明，TPC 提高了 1.67 倍，水解后单宁的去除率超过 50%。同时，在所有加工条件下，该工艺的效率都超过了 30%。这些结果为腰果苹果粉和相关产品的开发奠定了基础，从而提高了越南和世界腰果产业的经济效益。

期刊介绍： Open Chemistry is a peer-reviewed, open access journal that publishes original research, reviews and short communications in the fields of chemistry in an ongoing way. The central goal is to provide a hub for researchers working across all subjects to present their discoveries, and to be a forum for the discussion of the important issues in the field. The journal is the premier source for cutting edge research in fundamental chemistry and it provides high quality peer review services for its authors across the world. Moreover, it allows for libraries everywhere to avoid subscribing to multiple local publications, and to receive instead all the necessary chemistry research from a single source available to the entire scientific community.
