Sapota achras

Certain crops require a special climate and soil. Plants native to the American tropical rain forest give coca (Erythroxylum cocoa), avocado (Persea americana), the American counterpart of the mango (Spondias mombin), guava (Psidium guqjava), papaya (Carica papaya), the Brazilian nut (Bertholletia excelsa), and chewing-gum (latex om Achras sapota). 

Sapotilla, Chico (Achras sapota) is the fruit of the chicle tree, the source of the natural chewing gum base. The fruit has a very sweet taste with a pear-like, soft structure. The flavour is reminiscent of a mixture of pear with hazelnut. 

Chide. The partially evaporated, milky juice from Manilkara zapatiBa (Jaoq.) Gilly (Achras sapota LJ. Sapota-ceae. Habit. West Indies, Mexico and Central America. 

Usually, either the Z- or 5-isomer, but not both, is produced in any species with the major exception of chicle Achras sapota, Sapotaceae). Rubber occurs in the form of latex as minute particles which are accumulated in specialized cells or in vessels known as laticifers. 

Chicle, a mixture of Z- and -isomers of polyisoprene is isolated from Manilkara Achras) sapota (Sapotaceae). The biosynthesis of this material does not appear to have been examined. There is little doubt that there are two stereospecific enzyme systems metabolizing IPP in chicle latex, one producing rubber (2) and the other yielding gutta (Chari-wood and Banthorpe, 1978). Chicle is one of the few known examples where a mixture of the two structures occurs (Archer and Audley, 1973). Chicle, which is commonly used in chewing gum, has been partially replaced by synthetic substitutes (Loomis and Croteau, 1980). 

CijHpOn 342.299 Obt. industrially from whey. Occurs in mammalian milk (human 6-7%, cow 4-5%), fruits of Achras sapota, and a few other plants. V. inexpensive starting material for synthesis. Common excipient for tablets. Nutrient, sweetener, food blending agent. 

Occurs in acorns of Quercus spp. oak barks, leaves of Chamaerops humilis, seeds of Mimusops elengi and Achras sapota. Prisms (H2O). 

From the latex of Achras sapota, a mixture of cis- and tram-polyisoprene plus polysaccharides. 

Chicle is the coagulated latex from red and white sapodilla trees Achras sapota). Its main use is as chewing gum base.

Of the polyterpenes rubber, gutta-percha, and balata, our discussion will be restricted to the technically most important product, rubber. About 2,000 species of higher plants produce rubber but only a few of them, mainly from the families Apocynaceae, Asclepiadaceae, Compositae, Euphorbiaceae, and Moraceae, do so in sufficient quantity as to make its extraction technically worthwhile. A few of the more important species are listed in Table 5. The main source of rubber is the rubber tree Hevea brasiliensis. Achras sapota, the chicle of which provides the basic ingredient of chewing gum, is also included in the list.
