Chemical composition, antioxidant profile and physicochemical properties of commercial non-cocoa- and cocoa-flavoured plant-based milk alternatives

Abstract

In recent years, there has been a significant rise in the popularity of plant-based milk alternatives (PBMAs). This work examined the nutritional value, antioxidant profile and physicochemical characteristics of commercial non-cocoa- and cocoa-flavoured PBMAs. The examined products were either nut or oat-based ones. In the absence of protein fortification, the products' protein content was found to be low. Fat content was also low, whereas carbohydrate and sugar contents were related to sugar addition. Oleic, linoleic and α-linolenic acids were the primary unsaturated fatty acids. PBMAs have low Atherogenicity (AI) and Thrombogenicity (TI) indices and high hypocholesterolaemic:hypercholesterolaemic fatty acid ratio (h/H). The antioxidant profile significantly differed (P < 0.001) between non-cocoa- and cocoa-flavoured PBMAs. The antioxidant profile of cocoa-flavoured PMBAs improved due to the polyphenols present in cocoa beans. The physicochemical characteristics of the analysed PBMAs demonstrated great versatility. The nutritional profile of PBMAs also showed considerable variability, influenced by factors, such as product type and ingredient formulation. Additionally, differences in the nutritional composition and physicochemical properties were observed between non-cocoa and cocoa-based PBMAs.
