The Practice of Employing the Water Steeping Method to Extract Native Starch from Potatoes

Abstract

Many plants manufacture starch, a naturally occurring, renewable, and biodegradable polymer, as a means of storing energy. Starches can be used in a variety of ways due to their diverse structures and functions. Starch's functional characteristics can be altered and improved through a variety of physical, chemical, and enzymatic changes, enabling its application in a range of medicinal contexts. The Food and Drug Administration (FDA) of the United States has authorized certain starches, such as sodium starch glycolate (modified starch by chemical reaction), native starch and pregelatinized starch (a starch that has been physically enhanced), for use as a matrix or as an isolated excipient in drug delivery systems, such as capsules, granules, tablets, suppositories, implants, stents, transdermal, and ophthalmic systems. However, formulators are under pressure to find current excipients that accomplish the required set of functionalities due to the growing number of drug moieties with differing stability and physicochemical properties as well as the development of new drug production techniques and drug delivery systems. Whether used as excipients or as drug delivery systems, native and modified starches are widely used in pharmaceutical and biomedical applications. Recent advancements in pharmaceutical applications highlight the characteristics of potato starch. This paper provides a thorough review of making potato starches.
