Pectinase enzymes used today are naturally produced by fungi and yeasts (50%), insects, bacteria and microbes (35%) and various plants (15%), [4] but cannot be synthesized by animal or human cells. [5] In plants, pectinase enzymes hydrolyze pectin that is found in the cell wall, allowing for new growth and changes to be made.
When making jam or fruit butter, worrying about pectin is not really necessary since those preserves contain actual fruit matter, which provides body to the preserve.
Pectin is composed of complex polysaccharides that are present in the primary cell walls of a plant, and are abundant in the green parts of terrestrial plants. [5] Pectin is the principal component of the middle lamella, where it binds cells. Pectin is deposited by exocytosis into the cell wall via vesicles produced in the Golgi apparatus. [6]
Ficus pumila var. awkeotsang seeds contain pectin, a viscous gelation material. [12] Stirring and extracting the dried seeds with water for 15-20 minutes at room temperature, can obtain the gel easily. [12] It is noteworthy that Aiyu jelly does not require high temperature to form gel, which is different from other gel-forming material.
Pour some water over the bananas to fill up the jar, then cover it. Let the mixture sit for at least two or three days. By three weeks, the water should have absorbed all the potassium it can from ...

Pectinesterase (EC 3.1.1.11; systematic name pectin pectylhydrolase) is a ubiquitous cell-wall-associated enzyme that presents several isoforms that facilitate plant cell wall modification and subsequent breakdown. It catalyzes the following reaction:
The leaves can be used to make a pectin-rich gel that is something like tofu. [10] [9] The jelly is similar to grass jelly but it not usually called that, unlike other grass jelly plants. This green gel is called 神仙豆腐 (shénxiān dòufu, immortal/divine tofu) [9] or 观音豆腐 (Guānyīn dòufu, Guanyin tofu). [10]
