α-galactosidase is widely used in the food industry to break down complex sugars, such as raffinose and stachyose, found in legumes and vegetables. By doing so, it helps reduce gas and bloating often associated with consuming these foods, making them easier to digest. In the production of animal feed, it is added to improve nutrient absorption and enhance the digestibility of plant-based ingredients. Additionally, it plays a role in the sugar refining process, where it aids in the conversion of galactose-containing sugars into simpler forms. In biotechnology, α-galactosidase is utilized in research to study glycoside hydrolases and their mechanisms, as well as in the development of enzyme-based therapies for metabolic disorders. Its application also extends to the medical field, where it is used in diagnostic assays and as a potential treatment for conditions like Fabry disease.
