ARTICLE INFO	ABSTRACT
TYPE: Original scientific paper https://doi.org/10.17508/CJFST.2024.16.1.05 PDF	Spray drying is still the most significant method for polyphenols encapsulation, which offers numerous advantages such as facilitating the handling of unstable polyphenols from liquid extracts, improving their solubility, and enhancing stability, degradation protection, controlling or delaying the release, and masking unappealing tastes or odours. The selection of the most suitable wall material is one of the most challenging tasks. Over the past decade, there has been a growing trend toward using new types of wall materials for polyphenols encapsulation by spray drying, either as additional compounds or as complete substitutes for traditional wall materials. This review aims to present the properties and applications of such alternative green wall materials. The term “alternative green” refers to the origin of materials derived from by-products and waste.

	KEY CONTRIBUTION Spray drying remains the primary method for polyphenol encapsulation, offering advantages like handling unstable polyphenols, improving solubility, enhancing stability, and masking tastes or odors. However, selecting suitable wall materials poses a significant challenge. In recent years, there has been a surge in utilizing new wall materials, termed “alternative green,” derived from by-products and waste, either as additives or substitutes. This review provides insights into the properties and applications of these alternative green wall materials, aiming to advance sustainable practices in polyphenol encapsulation via spray drying.
