Food waste is a growing global concern. Green banana peels can contain a significant amount of starch by dry weight, making them a resource for waste reduction. Extracting starch from these peels is a sustainable way to create a versatile product.

Unripe, green bananas are known to contain a high concentration of starch, with some cultivars holding up to 70-80% on a dry weight basis, a figure that plummets as the fruit ripens. For those seeking to benefit from this abundant source of resistant starch, learning how to extract starch from unripe bananas is a straightforward and rewarding process.

Across the globe, approximately 60 million tons of starch are produced each year, with the process of preparing starch being a critical step in creating a fundamental ingredient for countless food and industrial applications. This complex process involves multiple stages, from initial raw material preparation to final drying and purification, ensuring a high-quality end product suitable for thickening, binding, and other uses.

Starch is a critical component in countless food and industrial products, derived from plant sources like corn, cassava, and potatoes. This article explores the essential stages of how to process starch, detailing the physical and chemical methods used for commercial extraction and purification.

While potatoes consist of up to 80% carbohydrates by dry weight, only a fraction of that is readily available as pure starch, requiring isolation. Learning how to isolate starch from potatoes is a straightforward kitchen science experiment that yields a versatile ingredient for cooking and baking.
