Papain, also known as papain, is a proteolytic enzyme. Papain is a low-specificity proteolytic enzyme contained in papaya (r). It is widely present in the roots, leaves and fruits of papaya, and is most abundant in immature milk. The active center of papain contains cysteine and is a thiol protease. It has the characteristics of high enzyme activity, high thermal stability, good natural health and safety, and is widely used in food, medicine, feed, daily chemical, leather and textile industries.
Papaya is distributed in tropical and subtropical regions of the world. Originating in southern Mexico and adjacent central America, it is now mainly distributed in Southeast Asia, Malaysia, the Philippines, Thailand, Vietnam, Myanmar, Indonesia, and India and Sri Lanka, Central and South America, the West Indies, the United States, Florida, Hawaii, Cuba, and Australia. China is mainly distributed in Guangdong, Hainan, Guangxi, Yunnan, Fujian, Taiwan and other provinces (regions).
. ) Plant pictures
.
. The leaves are large and clustered at the top of the stem, nearly shield-shaped, up to 1 cm in diameter, usually deeply split, each lobe is then pinnately split, and the petiole is hollow. Up to centimeters
. Flowers are unisexual or bisexual. Some varieties occasionally produce bisexual or female flowers on male plants and bear fruits. Sometimes a few male flowers appear on female plants. There are male, female and hermaphrodite plants. Male flowers: Arranged in panicles up to 1 meter in length. Drooping flowers. Sessile sepal base. Corolla. Creamy yellow. Tube-shaped. Tube-shaped. 1cm long. Corolla lobes are lanceolate. About .cm wide. .mm. Stamens are short, almost filament-free. Long filaments are white in color. White tomentous ovary reduced. Female flowers: solitary or arranged in corymbs. The leaves are short-stemmed or nearly sessile in the axils. The sepals are about 1 cm long and connate below the middle. The corolla lobes are separated and are creamy yellow or yellow-white. They are oblong or lanceolate. They are long.cm wide. .cm. Upper ovary, ovoid, sessile style, stigma several-lobed, nearly tassel-shaped.
. Hermaphrodite flowers: stamens are borne on a very short corolla tube near the base of the ovary or stamens are borne on a longer corolla tube and are arranged in a whorl. The tube is 1 cm long. The corolla lobes are oblong and about 1 in. cm wide mm ovary smaller than female plant ovary.
. When the berry flesh is ripe, it is orange or yellow, oblong, spherical, obovate, oblong, pear-shaped or nearly spherical, 1 cm or longer in length. The flesh is soft and juicy, with a sweet taste. The seeds are mostly ovoid. When mature, the outer testa is black and the inner seed is fleshy. Leather furniture wrinkles. Flowering and fruiting period throughout the year.

. )Product Application
.
. Papain has broad application and development prospects in medicine, food, beverage, chemical reagent, feed, textile, cosmetics, etc.
. Food Industry
. In the food industry, papain can be used for meat tenderization, beer clarification, biscuit loosening and other purposes.
. Beer clarifier
. The main cause of turbidity in beer refrigeration is that the protein in beer easily combines with polyphenols to form macromolecular complexes. The papain in the beer clarifier has a wide range of specificity for proteins that form turbidity. It can degrade large molecular proteins into small molecules and improve the solubility of the protein and polyphenol complex. On the other hand, papain is a biologically active enzyme. The protein can form a stable state balance with the polyphenols that cause refrigeration cloudiness of beer to prevent refrigeration cloudiness of beer.
. Meat tenderizer
. The use of papain can cleave the collagen and muscle fibers in meat to loosen the structure of the meat. Because papain is a cysteinyl protease, it can degrade collagen fibers and connective tissue proteins. It will degrade actomyosin and collagen into small molecule peptides and even amino acids, break muscle filaments and tendon filaments, and make meat tender and smooth. It also simplifies the protein structure to make it easier for the human body to digest and absorb after consumption.
. Biscuit loosening agent
. Utilizes the enzymatic reaction of papain to degrade the protein of the dough into small molecule peptides or aminoases, thereby reducing the tensile resistance of the dough and making the dough softer and more plastic. Elastic and easy to shape. The dosage depends on the processing method of the biscuit factory and the protein content in the dough. Research shows that it is better to add 10,000 units/g per kilogram of dough.
