Types of fermentation enzymes

Fermentation enzymes are crucial components in the fermentation process of various industries, such as food and beverage, pharmaceutical, and biofuel. Different types of fermentation enzymes play distinct roles in breaking down organic matter to produce valuable end products.

Generally, enzymes are proteins that help to speed up and catalyze biochemical reactions in the fermentation process. Fermentation enzymes are classified based on the organic compounds they break down into the following categories, such as carbohydrases, proteases, lipases, and others.

• Fermentation enzymes carbohydrases

  Carbohydrases are carbohydrates-hydrolyzing enzymes that break down carbohydrates into simple sugars during the fermentation process. They play a crucial role in various fermentation processes, such as brewing, baking, and biofuel production. Carbohydrases encompass an extensive group of enzymes, including amylases, glucoamylases, and alpha-galactosidases, among many others.

• Fermentation proteases enzymes

  Proteases are enzymes that break down proteins into peptides and amino acids. They are crucial in several fermentation processes, such as soy sauce and sauerkraut production. Similarly, proteases play important roles in the decomposition of organic matter by yeasts and fungi. In such cases, the amino acids produced by protease activity can serve as nutrients for yeast and fungal cells, thereby supporting their growth and reproduction. This, in turn, leads to the fermentation process and the eventual production of final products like alcohol, carbon dioxide, and other metabolites.

• Lipase enzymes for fermentation

  In simple terms, lipase enzymes are those that break down fat and oils into fatty acids and glycerol during the fermentation process. Lipases are crucial in several fermentation processes, such as cheese production and the breakdown of lipids in food products. In the context of alcoholic beverages like beer and wine, lipases may be involved in breaking down lipid compounds that could contribute to off-flavors. For example, some fatty acids can result in undesirable tastes when reacted upon by lipase enzymes during fermentation. This is one of the reasons why controlling enzyme activity during fermentation is essential for achieving desired flavors in fermented products.

• Other fermentation enzymes

  These are various enzymes involved in fermentation that break down different organic compounds. For instance, pectinase is a group of enzymes that break down pectin, a polysaccharide found in plant cell walls and fruit. The primary role of pectinase enzymes in fermentation is to break down pectin and thereby enhance juice extraction, clarification, and textures. Cellulases are another example of fermentation enzymes. These enzymes catalyze the breakdown of cellulose, which is a complex sugar and the primary structural component of plant cell walls. Cellulases are important in the fermentation of biomass to produce biofuels, such as ethanol. This is because they break down plant material to release fermentable sugars.

Specification and maintenance of fermentation enzymes

Specifications

• Particle Size: The fermentation enzyme powder typically has a fine particle size that increases surface area and solubility. Fermentation enzymes are often measured in microns, and the precise particle size may vary depending on the enzyme type and specific application requirements.
• pH : Fermentation enzymes function best within a specific pH range. Whether they work best in acidic (pH 6-9) or alkaline (pH 4-6) settings depends on the enzyme type. The fermentation process may be influenced or depend on enzyme activity at the right pH levels.
• Moisture content: Fermentation enzyme powder's efficiency may be impacted by its moisture content. The moisture content is typically expressed as a percentage and needs to be kept low (2-5%) to assure the stability and shelf life of the product.
• Temperature range: Fermentation enzymes may have an optimum temperature for activity, which can range from 30 to 70 degrees Celsius or higher. Enzyme fermentation effectiveness and yield depend on the temperature of the enzyme.
• Shelf life: Fermentation enzyme powders typically have a shelf life of 1–5 years if kept properly. Products with the highest potency will have a longer shelf life.
• Packaging: Enzyme powders for fermentation are often found in airtight, moisture-proof containers like plastic jars or multi-layered composite bags. These are made for industrial use and easily accommodate storing and transporting the goods.

Maintenance

• Environmental control: For fermentation enzymes to survive environmental control, temperature and moisture must be maintained within a specific range. Keep ferment enzymes away from heat sources and direct sunlight, and try to keep the surroundings dry and well-ventilated to prevent dampness and mold growth.
• Airtight storage: To maintain enzyme fermentation activity, tightly store the originals and containers. Make sure the lid of the container is tightly closed after using it to prevent air, moisture, and contaminants from getting inside.
• Separate storage: Avoid storing fermentation enzymes with other chemicals or hazardous items. Keep them apart from one another to avoid pollution or chemical reactions.
• Protect from light: Since fermentation enzymes are light-sensitive, avoid exposing them to bright light. If not in use, keep them in a dark area to shield them from the sun or artificial lighting.
• Attention to use: To ensure enzyme stability and activity, wash and sterilize all fermentation enzyme-containing equipment and utensils before use. Try not to touch the enzymes with your bare hands.

Uses of fermentation enzymes

Industrial-scale usages of fermentation enzymes are primarily seen in the food industry, but the following six industries with enzyme companies use enzymes for various applications:

• Food Fermentation

  Fermentation enzymes are crucial in food processing and production, such as brewing, baking, dairy products, nutrition supplements, making organic acids like citric and lactic acid, pickled products, and solvent. Enzymes like amylases, proteases, and lipases break down carbohydrates, fats, and proteins to produce specific flavors, textures, and nutritional profiles.

• Textile Industry

  Textile uses fermentation enzymes like cellulases and amylases. Cellulases improve fabric quality by enhancing softness, brightness, and durability. Amylases remove starch-sized substances, promoting smoother weaving and improving fabric quality.

• Pulp and Paper

  Pulp and paper manufacturers use fermentation enzymes to break down lignin and cellulose, which makes trees fibrous. The pulp and paper product becomes lighter and smoother after the fermentation enzymes have been added. Less chemical waste is produced after fermentation enzymes have been used in the paper-making process.

• Feed Additives

  Fermentation enzymes are employed as feed additives in animal nutrition to improve the digestibility and bioavailability of nutrients in animal feed. Enzymes such as phytase and protease are added to optimize nutrient absorption and enhance animal growth.

• Bioremediation

  Fermentation enzymes are utilized in bioremediation applications to degrade pollutants and contaminants in the environment. Enzymes such as lignin peroxidase and organophosphate hydrolase can degrade complex organic compounds, pesticides, and hydrocarbons, aiding in environmental cleanup processes.

• Bioenergy production

  Fermentation enzymes play a vital role in bioenergy production. They break down biomass, such as agricultural residues, food waste, and plant materials, into fermentable sugars. These sugars are subsequently converted into biofuels like ethanol through fermentation, powered by specific microorganisms.
