Chitinase in banana

Chitinases occur naturally in many common foods. Bananas significant levels of chitinase, as defense against fungal and invertebrate attack. Proteomic analysis revealed that chitinases are the most abundant proteins in the pulp of unripe bananas.

Chitin, the second most abundant polysaccharide in nature after cellulose. Chitinases are enzymes that degrade chitin. Chitinases contribute to the generation of carbon and nitrogen in the ecosystem. Chitin and chitinolytic enzymes are gaining importance for their biotechnological applications, especially the chitinases exploited in agriculture fields to control pathogens.

Chitinases are involved in many physiological and bioconversion processes. It plays a major role in nutrition and parasitism in bacteria. In case of plants and vertebrates, it is involved in the defense mechanisms.

Chitinases are involved in morphogenesis in invertebrates, protozoa and fungi. Baculoviruses also produces chitinases for pathogenesis. Chitotriosodase enzyme was also used as marker of lysosomal storage disorder.

Chitinases are a well‐known group of food allergens, mainly of plant origins. Even if many of them have been detected in fresh fruits and berries, and therefore not subjected to any food processing before assumption, it also emerged that chitinases present in processed food (flour, beer and polenta) can be allergenic.

Allergy to banana

Allergy to banana
Type 1 allergy mean that the people allergy to banana. It also name as contact allergy. There is a protein called chitinase, which can cause body can overreact and treat the protein as foreign body. The protein called chitinase also found in avocado and kiwi fruit.

History showed that the banana originated in Malaysia 4000 years ago before it spread to Philippines and India. Today bananas are grown in most tropical and subtropical regions around the world with the main commercial producers located in Central America.

Another chemical found in banana is serotonin, which symptom including cramping, flushing of the skin, headache, and heart palpitations. The severity of the symptoms is dependent on the amount the histamine like substance ingested and the lack of the histamine metabolizing enzyme diamine oxidase in your system.

Most reactions happened last less than a day and can involve a rash on the skin, cramps, diarrhea, nausea, and vomiting, runny nose, watery eyes, wheezing and coughing.
