Fruit tree gum

Polysaccharide materials Starch, cellulose, plant gums (arabic gum, tragacanth, karaya, ghatti, guar, locust bean, fruit tree gum) Paper, paint binders, adhesives... 

Although the pyrolysis of some classes of polysaccharide materials has been studied quite extensively in the food, petrol and tobacco industry, very little has been published specifically on polysaccharide binders (arabic gum, tragacanth gum, fruit tree gum, honey and starch). The pyrolysis of glucane based polymers, especially cellulose, has been studied in detail [6,55], highlighting how anhydrosugars and furan derivatives are the main pyrolysis products, together with one-, two- and three-carbon aldehydes and acids. 

Plant gums may be defined as those substances of plant origin which are obtained as exudations from the fruit, trunks or branches of trees spontaneously or after mechanical injury of the plant by incision of the bark or by removal of a branch, or after invasion by bacteria or fungi. 

Gum is found upon the hark of certain trees as an exudation, which gradually concretes in. transparent or translucent amorphous drops. It may also he detected, in greater or Icsb quantity, in the juices of most plents and fruits.

Marmosets and tamarins feed on the gum and sap of trees, which they obtain by scraping the bark with their teeth. All other primates that eat gum or sap use holes dug by insects. Marmosets and tamarins also eat fruit, flowers, and insects. 

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. 

Botanists disagree as to the nomenclature and identity of acacia trees, particularly in reference to species, subspecies, and varieties. Formerly all the gum arabic was believed to be collected from Acacia arabica. There seems to be agreement now that the tree is Acacia verek, which some botanists consider a variety of Acacia arabica. Other authorities state that the common acacia in the lands from the Red Sea across the African continent to Cape Verde on the Atlantic Coast is the Acacia verek. Still others set Acacia Senegal aside as a separate and distinct species. The acacias differ in tree size, shape, and size of leaf, flower, or fruit as do other families of plants. These greater or lesser differences are evident in the acacia trees of Morocco, Senegal, Upper Egypt, Arabia, and India, but the differences in their exudations are not readily distinguishable in a chemical sense. 

Cellulose not only provides the support substance of wood, but also that for all other plants. Flax stalk husks provide linen and hemp is obtained from the leaves of the sisal plant. Cotton fibers are recovered from the seed hairs of the cotton bush. What are known as vegetable gums, which are also polysaccharides, are to be found in other seeds and algae. Starch is recovered from grain seeds, and starch is a mixture of the polysaccharides amylose and amylopectin. Pectin, an acidic polysaccharide, is provided by fruits. Latices containing the polyprenes natural rubber, balata, gutta percha, or chicle are obtained from certain trees and plants. 

KINDS OF FIBER. Fiber may be obtained from diverse sources, such as grains, vegetables, fruits, nuts, seaweed, gum trees, and the laboratory of the organic chemist. Therefore, it is worthwhile to consider the plant constituents that comprise most of the fiber in the human diet.
