The Enzymatic Journey Invertase in Food Biochemistry

Enzymes play a crucial role in the field of food biochemistry, as they are responsible for catalyzing various chemical reactions that occur during food processing and digestion. One such enzyme is invertase, which plays a significant role in the breakdown of sucrose into its constituent monosaccharides, glucose, and fructose.

Invertase is an enzyme classified under the glycoside hydrolase family 32 (GH32) and is widely distributed among plants, animals, and microorganisms. It can be found naturally in many fruits such as bananas, pineapples, and strawberries. Additionally, it is also produced by certain yeasts and bacteria.

The primary function of invertase lies in its ability to hydrolyze sucrose into glucose and fructose through a process known as inversion. This reaction occurs when water molecules attack the glycosidic bond between glucose and fructose units within the sucrose molecule. The resulting products are two simple sugars that can be easily absorbed by our bodies.

During food processing or cooking methods involving high temperatures like baking or boiling, invertase activity may decrease due to denaturation or degradation. However, some studies have shown that low-temperature treatments can enhance invertase activity instead. For example, refrigeration has been found to increase invertase levels in certain fruits like tomatoes.

Invertase’s importance extends beyond its role in breaking down sucrose into simpler sugars; it also contributes to flavor development during fermentation processes. Yeast strains used for brewing beer or making wine produce invertases that convert complex carbohydrates present in grains or grapes into fermentable sugars like glucose and fructose. These sugars serve as fuel for yeast metabolism during fermentation while imparting desirable flavors to the final product.

Moreover, recent research has highlighted potential applications of invertases beyond their traditional use in food production. For instance, invertase has been utilized in the invertase enzyme production of high-fructose corn syrup (HFCS), a widely used sweetener. In this process, invertase is employed to convert glucose into fructose, resulting in a sweeter product with improved taste and stability.

Invertase also plays a role in the pharmaceutical industry. It has been investigated for its potential use in drug delivery systems due to its ability to break down complex carbohydrates found on cell surfaces. By modifying these carbohydrates using invertase, scientists aim to enhance drug targeting and improve therapeutic efficacy.
