Which Macromolecules Do Meat Tenderization Enzymes React With?

Commercial meat tenderizers, such as papain and bromelain, are enzymes that play a crucial role in the conversion of muscle into meat. Enzymatic glycolysis, proteolysis, and lipolysis are essential for the process, which involves breaking down tough connective tissues in meat to target specific proteins. Enzymes, such as papain, bromelain, and actinidin, are natural catalysts that speed up chemical reactions and play a significant role in the tenderizing process.

Some fruits, like pineapple, papaya, and kiwi, contain enzymes that can be used to tenderize meat before cooking. Most exogenous enzymes used to tenderize meat have an optimal activity in the 50-70°C range, and most of their activity occurs during the cooking process. Meat tenderizing powder contains an enzyme that weakens the bonds between muscle fibers when coming into contact with meat, known as protein denaturation.

Myofibril disruption at the N 2-line level is a key role in meat tenderization, as it affects the biochemical and ultrastructural changes occurring in meat. Enzymatic glycolysis, proteolysis, and lipolysis play a key role in the conversion of muscle into meat. Raw fruits, such as those containing papain, can be used to tenderize meat before cooking due to their enzymes that break down proteins.

Meat processing enzymes used in meat tenderizing include vegetable enzymes papain, bromelain, and ficin. The two major enzymes derived from plants that aid in meat tenderization are papain and bromelain, which are proteolytic in nature. Treating meat with papain, a protease enzyme, before cooking makes it more tender by breaking down proteins and connective tissue within the meat.

What things tenderize meat?

And fish lemon juice. And I’m going to let this set probably about four hours in the icebox. Bring it out about 40 minutes let it come to room temperature. Before we throw it on the grill.

What enzymes break down red meat?

Proteases. Also called peptidases, proteolytic enzymes, or proteinases, these digestive enzymes break down proteins into amino acids.

Digestive enzymes are substances that help you digest your food. They are secreted (released) by the salivary glands and cells lining the stomach, pancreas, and small intestine. There are several digestive enzymes, including amylase, maltase, lactase, lipase, sucrase, and proteases.

Some conditions can result in digestive enzyme deficiencies, such as lactose intolerance or exocrine pancreatic insufficiency. In that case, supplementation with foods, over-the-counter supplements, or prescription digestive enzyme supplements may be necessary.

Keep reading to learn about different types of digestive enzymes and how they work.

What is the chemical reaction in meat tenderizer?

Biochemistry of Meat Tenderization with Sodium Bicarbonate. Sodium bicarbonate, when applied to meat, initiates a series of biochemical reactions that fundamentally alter the protein structures within the meat:

– Denaturation of Proteins. Sodium bicarbonate raises the pH on the surface of the meat, causing proteins like collagen and myofibrillar proteins to denature. This denaturation process leads to the unwinding of protein structures, making them less tough and more tender.

– I ncreased Water Retention. The higher pH changes the electrical charges of protein molecules, enhancing their ability to bind water. This helps the meat remain moist and tender during cooking.

– W eakening of Protein Bonds. Alkaline conditions weaken the bonds within protein molecules, particularly the cross-links in connective tissue. This transformation reduces the toughness of the meat, converting tough collagen into softer gelatin upon cooking.

What enzymes are used to tenderize meat?

Plant proteases, such as papain, bromelain, and ficin, are commonly used for meat tenderization due to their lower cost, improved sensory attributes, and the presence of bioactive compounds like antioxidants and antimicrobial effects. However, uncontrolled plant protease action can lead to excessive tenderization and poor quality due to an indiscriminate breakdown of proteins. The food industry faces challenges such as higher costs of separation and purification of enzymes, unstable structure, and poor stability due to autolysis. To address these issues, the meat industry is targeting the recycling of enzymes and improving their stability and shelf-life through immobilization, encapsulation, protein engineering, medium engineering, and stabilization during tenderization.

Meat tenderness is crucial for determining the eating qualities of meat, such as juiciness, mouthfeel, palatability, flavor, texture, and appearance. Consumers are more likely to purchase meat that is guaranteed to be tender, as it influences overall palatability and acceptance. Poor meat tenderness results in significant losses to the meat industry. The components involved in meat tenderness include connective tissue, sarcomere length, post-mortem changes, proteolytic potential, and degradation of myofibrillar proteins. Tenderness is a primary concern for red meat due to its production practices and age at slaughter.

What is the science behind tenderizing meat?

Physically Tenderizing Meat. These amino acids can be broken down in a few different ways. The most common way to break those bonds is to apply physical force, either through a meat mallet or an electric meat tenderizer. The physical force will break down these bonds between the amino acids, resulting in the meat becoming softer over time.

Too Much Force. Applying too much force or doing so for too long will eventually result in the meat itself breaking apart, essentially ruining it and rendering it unsuitable for serving.

Utilizing Acidic Ingredients. Marinating the cut of meat in vinegar, lemon juice, or other acidic liquids will break down the protein in the meat. These acids will eat away at the amino acids until it becomes soft and ready to serve.

What are the three types of enzymatic reactions?

What are the factors that make meat tender?

Meat tenderness is influenced by the biochemical properties of muscle fibers as well as connective tissue matrix and is improved by aging – primarily due to degradation of cytoskeletal proteins.

What is the process of tenderizing meat?

In cooking, tenderizing is a process to break down collagens in meat to make it more palatable for consumption. Research in Australia and in New Zealand has shown that when stress in transport, yarning, handling and slaughter was minimized beef meat was consistently at the tender end of the scale regardless of breed.

What does meat tenderizer do to proteins?

Meat tenderizer enzymes are proteins that are used to break down the proteins and fibers in meat, resulting in a more tender and delicious product.

One of the main benefits of using meat tenderizer enzymes is that they can enhanced meat texture. For example, enzymes can be used to tenderize tough cuts of meat, making them more appealing to consumers. They can also be used to improve the texture and mouthfeel of meat, enhancing the overall eating experience. This not only reduces food waste but also opens new possibilities for creative dishes.

Meat tenderizer enzymes can also be used to improve the efficiency and productivity of the meat processing industry. For example, enzymes can be used to reduce the time and energy required to tenderize meat, allowing manufacturers to produce more product in a shorter amount of time. This can help to reduce production costs and improve the overall profitability of the industry.

Meat tenderizer enzymes are commonly used in the production of various meat products, including beef, pork, and poultry. They are also used in the production of processed meat products, such as sausages and deli meats. Meat tenderizer enzymes are also used in the production of plant-based meat substitutes, such as tofu, steak vegetarian and nugget vegetarian.

What are the enzymatic reactions in meat?

Meat aging is a process that involves transformations in the animal’s muscle after slaughter, resulting in changes in color, tenderness, and aroma. These biochemical processes are mainly caused by endogenous enzymes, leading to glycolysis, proteolysis, and lipolysis. In glycolysis, glucose is metabolized to produce lactic acid, which lowers muscle pH and depletes energy reserves (ATP). This energy depletion leads to the degradation of myofibrillar proteins by endopeptidases and exopeptidases. Endogenous proteases play a crucial role in proteolysis, while exogenous proteases secreted from microorganisms involved in meat fermentation increase the concentration of peptides and amino acids. Lipolysis occurs in muscle and adipose tissue.

The products resulting from protein and lipid degradation are precursors of the characteristic flavor and aroma of meat and meat products. The fragmentation of myofibrils also leads to changes in texture that lead to meat softening. Post mortem changes in the muscle, which affect the organoleptic properties of meat, are mostly related to the action of enzymes.

Enzymatic reactions in the transformation of muscle into meat occur at relatively low reaction rates and are affected by various intrinsic and extrinsic factors. Exogenous enzymes are used in the meat industry to produce restructured meat, obtain bioactive peptides, and induce meat tenderization. The application of emerging technologies in meat processing could intensify enzymatic reactions involving endogenous and exogenous enzymes, ensuring food safety and preserving the quality and safety of processed food products.
