Pectin is a polysaccharide complex extracted from the peel and pulp of citrus fruits, lemons, oranges, and grapefruits. Natural citrus pectin is commonly used as a food additive, providing excellent gelling, stabilizing, emulsifying, thickening, and suspending properties. Pectin is also a pure, natural, water-soluble dietary fiber without any toxic side effects. It plays a crucial role in health foods and is gradually gaining recognition and application.
Modified citrus pectin, also known as small-molecule citrus pectin, is the hydrolysis product of natural citrus pectin. After hydrolysis, the molecular weight ranges from 2,000 to 50,000, and the degree of esterification is 2% to 30%. Hydrolysis cleaves the pectin chains, reducing the molecular weight, and lowering the degree of esterification. Modified citrus pectin is easily absorbed by the intestines and enters the bloodstream, directly stimulating the systemic immune system. It can also bind to heavy metals in the blood, promoting their excretion.
Modified citrus pectin has four main functions: cancer prevention and treatment, cardiovascular regulation, heavy metal elimination, and improving the quality of life for diabetic patients.
Modified citrus pectin can support cardiovascular health.
Modified citrus pectin can effectively lower blood sugar levels and has a protective effect against hyperlipidemia caused by high blood sugar. Furthermore, modified citrus pectin can improve obesity and reduce high blood lipid levels.
Modified citrus pectin has excellent anti-cancer activity.
Research has shown that low-molecular-weight citrus pectin is a competitive inhibitor of the galectin-3 ligand in vivo. It shares significant sequence similarity with Bcl-2, containing the NWGR motif at its carboxyl terminus. This motif is required for Bcl-2 to inhibit apoptosis. Bcl-2 is an oncogene that inhibits apoptosis, acting on endogenous apoptosis signaling pathways.
Research experiments have shown that modified citrus pectin has a strong inhibitory effect on PC3 prostate cancer cells, with an inhibition rate of 38% at a medium dose (2.5 mg/mL) and 80%-90% at a high dose (5-10 mg/mL).
Modified citrus pectin improves the quality of life for diabetic patients.
After entering the gastrointestinal tract, modified citrus pectin forms a gel filtration system within the intestine, altering the digestion and absorption of nutrients, including monosaccharides and disaccharides. It also forms a barrier layer on the surface of the small intestinal mucosa, hindering glucose absorption and allowing excess glucose to be excreted. Furthermore, modified citrus pectin can reduce the secretion of the gastrointestinal hormone "gastric inhibitory polypeptide," thereby reducing glucose absorption. Low-molecular-weight citrus pectin offers a new avenue for drug and dietary treatment of diabetes. It has a protective effect against hyperlipidemia caused by high blood sugar levels.
Modified citrus pectin has a preventive and therapeutic effect against lead poisoning.
Animal and clinical studies have confirmed that the natural chelation function of modified citrus pectin is currently the most ideal and successful solution for addressing heavy metal contamination in the body. Therefore, it has the potential to prevent a variety of diseases, particularly in the removal of harmful cells and toxins from the body. Unlike common chemical chelators, modified citrus pectin detoxifies by removing harmful toxins like lead, mercury, and arsenic from the body without affecting the levels of other key minerals like calcium, magnesium, and zinc.
