Slow Set High Methoxyl Pectin (e440i) is extracted from the peels of citrus fruit. Pectin consists of a complex set of polysaccharides that are present in most primary cell walls of plants. The main use for pectin is as a gelling agent, thickening agent and stabilizer in food. The classical application is giving the jelly-like consistency to jams or marmalades, which would otherwise be sweet juices. Pectin can also be used to stabilize acidic protein drinks, such as drinking yogurt, and as a fat substitute in baked goods.
Slow Set High Methoxyl Pectin works best at pH from 2.8 to 3.2. It forms gels more slowly which prevents premature gelation and facilitates filling of large scale jam and jelly batches.
