Bromelain is a proteolytic enzyme that is commercially produced from the fruit or stem of pineapples. It is often used as a meat tenderizer, targeting and breaking down collagen, the connective tissue in meat. In addition, bromelain can be used to break down proteins in beer to prevent cold turbidity and improve stability. It is also used to hydrolyze dairy, animal, and plant-based proteins to reduce allergenicity and improve digestibility. In the context of mushrooms, bromelain has been employed in the production of mushroom protein hydrolysates, which are potential flavor enhancers in food applications, particularly in chicken soup.

What You'll Learn
Bromelain is a protease enzyme that breaks down proteins
In the food industry, bromelain is used to clarify beer, preventing cloudiness by breaking down proteins that can cause turbidity. It is also used as a meat tenderiser, targeting and breaking down collagen, the connective tissue in meat, which softens muscle fibres. Additionally, bromelain is used to reduce the allergenicity of cow's milk by hydrolysing proteins such as alpha-lactalbumin and beta-lactoglobulin, which are recognised as allergens for humans.
Bromelain's ability to break down proteins also has therapeutic benefits. It can be used to manage sinusitis, bronchitis, angina pectoris, surgical trauma, and thrombophlebitis. It is also a potent anti-inflammatory agent, effective in treating osteoarthritis, dental plaque, gingivitis, and various infections. Furthermore, bromelain aids in dental bleaching by weakening the protein component of the pellicle layer that adheres to the tooth surface, enhancing the effectiveness of hydrogen peroxide treatments.
In the production of mushroom protein hydrolysates, bromelain is used to break down the proteins in mushrooms. This process results in hydrolysates with improved taste, aroma, and mouthfeel, making them suitable for use as flavour enhancers in food applications, such as chicken soup.

It's derived from pineapple and used in food production
Bromelain is a proteolytic enzyme derived from pineapples, specifically the stem, although it is present in all parts of the plant. It has a long history of use in folk medicine and was first isolated by Venezuelan chemist Vicente Marcano in 1891. It is mainly produced in regions where pineapples are grown, such as Thailand and Malaysia.
In food production, bromelain is commonly used as a meat tenderizer, breaking down the cross-links between myofibrillar meat proteins to improve the eating quality. It is often found in prepared meat products like meatballs and marinades. Additionally, bromelain is used in baking, to prevent the browning of cut fruit, and in the manufacturing of textiles and cosmetics.
Bromelain is also used in toothpastes as a tooth plaque removal enhancer. It has been studied for its potential therapeutic effects on various health conditions, such as acute rhinosinusitis, rheumatoid arthritis, and osteoarthritis. However, there is limited scientific evidence to support its effectiveness in most of these applications.
While bromelain is generally considered safe, certain precautions should be taken. For instance, it may cause an allergic reaction in individuals allergic to pineapple or other plants. It can also increase the risk of bleeding, especially during surgery, and interact with certain medications like antibiotics.

It has been used to improve the taste of chicken soup
Bromelain is a protease that can be produced from all parts of the pineapple plant (Ananas comosus). It is a combination of several thiol endopeptidases and other protease inhibitors. It is known to break the cross-links between myofibrillar meat proteins, improving the eating quality of meat.
The use of bromelain in food products has been studied extensively. It has been found to improve the quality and nutritional value of local Indonesian food. For example, it is used in the production of tempeh gembus, virgin coconut oil, and fish sauce from dumbo catfish.
In one study, the effect of bromelain on chicken soup was investigated. The aim was to examine the physicochemical properties of stem bromelain-treated mushroom protein hydrolysates and to evaluate their taste-enhancing properties. Shiitake, oyster, bunashimeji, and enoki mushrooms were selected to produce protein hydrolysates by stem bromelain hydrolysis. The mushroom protein hydrolysates were then added to chicken soup, and their taste-enhancing effects were evaluated by 58 untrained panelists.
The results of the study showed that while soup with MSG had the highest score for the tested attributes, soups with bunashimeji and oyster mushroom protein hydrolysates showed higher aroma, taste, mouthfeel, and overall preference scores than the negative control, which contained neither MSG nor any hydrolysates. This finding suggests that bunashimeji and oyster mushroom protein hydrolysates have the potential to be used as taste enhancers in food applications, including chicken soup.
In summary, bromelain has been shown to improve the taste of chicken soup when used to produce mushroom protein hydrolysates. These hydrolysates can enhance the aroma, taste, mouthfeel, and overall preference of the soup, making them promising natural taste enhancers for food applications.

It can be used to tenderise meat by breaking down collagen
Bromelain is a natural enzyme derived from the stems and fruit of pineapple plants. It is a combination of several thiol endopeptidases, protease inhibitors, glucosidase, cellulase, phosphatase, peroxidase, and escharase. Bromelain is known to have a variety of fibrinolytic, anti-edematous, antithrombotic, and anti-inflammatory effects.
Bromelain is a cysteine protease that targets the peptide bond inside the protein molecule where they have a cysteine amino acid. This hydrolysis breaks down the larger protein molecules, by breaking the peptide bonds, into smaller parts through the combination with water.
One of the most common food applications of bromelain is as a meat tenderizer. Collagen is the connective tissue in meat that gives it structure and toughness. Bromelain targets this collagen, breaking it down and softening the muscle fibres in the meat. The tenderizing process breaks down the structural binding of collagen, making the meat easier to chew.
When used shortly before cooking, bromelain efficiently softens the meat without compromising its texture. The enzymes are neutralized by heat, so they stop working once the meat is cooked. If left on the meat for too long, bromelain can break down the collagen to the point where the meat becomes noticeably mushy and unappetizing.
Bromelain is a versatile and valuable enzyme in various industries, including food processing, beverage production, pharmaceuticals, and cosmetics. Its ability to efficiently break down proteins makes it a useful tool for meat tenderization, dough relaxation, and improving the stability and shelf life of beverages.

It has been studied for its potential health benefits
Bromelain is a mixture of enzymes derived from the pineapple fruit or stem. It is a protein-digesting enzyme that breaks down proteins in the body. It is often sold as a health supplement or skin cream. While it is a natural substance, it can have side effects, and people with pineapple allergies should avoid it. It is also not recommended for those taking blood-thinning medications or who have bleeding disorders.
Bromelain has been studied for its potential health benefits, including its anti-inflammatory properties. Research suggests that it can help reduce inflammation and swelling, promote wound healing, ease digestion, reduce pain, benefit heart health, and reduce allergies or asthma. It has been found to help the body absorb nutrients and medications more efficiently. Studies have also shown that it can be beneficial for people with gastrointestinal issues, as it decreases colonic inflammation and reduces the secretion of pro-inflammatory cytokines that damage the gut lining.
Additionally, bromelain has been studied for its therapeutic effects in managing sinusitis, bronchitis, angina pectoris, surgical trauma, and thrombophlebitis. It may also have applications in dental care, as it can aid in dental bleaching when used in conjunction with hydrogen peroxide.
Bromelain has also been explored as an alternative medicine for obesity. Some studies indicate that it can help downregulate fatty acid-binding proteins and reduce triglyceride accumulation, potentially inhibiting adipogenesis and the formation of fat cells.
While bromelain has shown promise in these areas, it is important to note that there is a lack of large-scale human research studies to back up its effectiveness. The specific amount of bromelain that a person should take to observe health benefits has also not been established, and the dose may depend on factors such as the type of bromelain and preparation.
