Bromelain The purified proteolytic substance derived from the pineapples Ananas comosus and Ananas bracteatus L. (Fam. Bromeliaceae). Produced as a white to light tan, amorphous powder soluble in water (the solution is usually colorless to light yellow and somewhat opalescent), but practically insoluble in alcohol, in chloroform, and in ether. Major active principle bromelain. Typical applications used in the chillproofing of beer, in the tenderizing of meat, in the preparation of precooked cereals, in the production of protein hydrolysates, and in baking.

The volatiles of fresh pineapple (Ananas comosus [L] Merr.) crown, pulp and intact fmit were studied by capillary gas chromatography and capillary gas chromatography-mass spectrometry. The fnjit was sampled using dynamic headspace sampling and vacuum steam distillation-extraction. Analyses showed that the crown contains Cg aldehydes and alcohols while the pulp and intact fruit are characterized by a diverse assortment of esters, h rocarbons, alcohols and carbonyl compounds. Odor unit values, calculated from odor threshold and concentration data, indicate that the following compounds are important contributors to fresh pineapple aroma 2,5-dimethyl-4-hydroxy-3(2H)-furanone, methyl 2-methybutanoate, ethyl 2-methylbutanoate, ethyl acetate, ethyl hexanoate, ethyl butanoate, ethyl 2-methylpropanoate, methyl hexanoate and methyl butanoate.

PINEAPPLE, Ananas comosm (L). Merr., Family Bromdiaceae and PAPAYA, Carica papaya, L., Family Carica-ceae are two plants which contain proteolytic enzymes bromelain in pineapple and papain in unripe papaya fruits. These two are proteases and can degrade protein in meat in cases where there is a deficiency of digestive enzymes. Papain is widely used as a meat tenderiser as are ficin from Ficus glabra and the bromelains. It is also used in more purified form (Chymopapain) in chemonucleolysis to shrink ruptured or slipped vertebral discs. 

Bromelain is the collective name for closely related proteolytic enzymes found in tissues of the plant family Bromeliaceae, of which pineapple, Ananas comosus, is the best known. Two distinct types of pineapple bromelain are recognized stem bromelain (EC 3.4.22.32), the major proteolytic cysteinyl protease in pineapple stem, and fruit bromelain (EC 3.4.22.33), formerly called bromelin, which is the major proteolytic component in pineapple fruit [1]. Stem bromelain has been known under a variety of synonyms, namely, pineapple stem bromelain, EC 3.4.4.24 (formerly), EC 3.4.22.5 (formerly), included in EC 3.4.22.4 (formerly), ananase, bromelase, pinase, extranase, traumanase, pineapple enzyme, and juice bromelain.

Pineapple (Ananas comosus), which is native to Brazil, is a tropical plant with leaves rich in cellulose. Being relatively inexpensive and abundantly available, pineapple fiber may be considered for polymer composite reinforcement. Today, pineapple leaves are a by-product of pineapple cultivation [3]. Devi et al. [43] investigated the dynamic mechanical behavior of pineapple leaf fiber-reinforced polyester composites. Threepopnatkul et al. [44] studied the effects of fiber surface treatments on the performance of pineapple leaf fiber-carbonate composite.

Neales (1973 b), using pineapple (Ananas comosus) demonstrated a correlation between the ratio of dark to light CO2 fixation and night temperature. As night temperature increased (day at 27.5° C) from 15° to 35° C, there was less night-time CO2 fixation relative to day-time fixation (see Chap. 5.1.3).
