Edible kernels are popular food items since ancient times. Although in-shell nuts are naturally protected and relatively shelf stable, convenience demands require their commercialization in shelled form. However, whereas shelled kernels are more convenient, they are more exposed to oxygen, and thus more susceptible to oxidative rancidity and loss of crunchiness, which negatively affect the product acceptability. In this review, we discuss the role of edible coatings in extending stability of edible kernels, which is an opportunity to be better explored by the industry. The discussion also includes the role of antioxidants in the context of active coatings. Finally, future prospects and research challenges are addressed. This article is protected by copyright.

简而言之：可食仁包衣的前景与挑战

自古以来，可食用的仁是受欢迎的食品。尽管带壳坚果受到天然保护并且相对货架稳定，但对便利性的需求需要它们以带壳形式进行商业化。然而，尽管去壳仁更方便，但它们更容易暴露在氧气中，因此更容易发生氧化酸败和松脆度下降，从而对产品的可接受性产生负面影响。在这篇综述中，我们讨论了食用包衣在延长食用仁稳定性方面的作用，这是行业更好地探索的机会。讨论还包括抗氧化剂在活性涂层中的作用。最后，讨论了未来的前景和研究挑战。本文受版权保护。版权所有。
