Summary Xyloglucan (XG) is an under‐utilised mucoadhesive hemicellulosic biopolymer extracted from tamarind industrial waste (tamarind seed), a commercial source. XG is a low‐cost, non‐toxic, biocompatible, and stable biopolymer at a wide range of pH, temperature, and ionic solutions. It is generally recognised as safe (GRAS) by FDA and used as a food additive as a gelling agent, emulsifier, thickener, stabiliser, etc. This review aims to explore the utilisation of tamarind industrial waste for the production of XG and their application in the food industry as alternative hydrocolloids by providing adequate knowledge in production, extraction, properties, chemical modification, and interactions. It is also highlighted that XG has been extensively studied recently in manufacturing gluten‐free foods (rice bread), food quality assessment, and packaging film production.
