Application Solutions
Pharmaceutical & Nutraceutical Industry
Modified Citrus Pectin (MCP) is widely used for adjunctive anti-cancer therapy, while also helping detoxify heavy metals such as lead, mercury, and arsenic, and supporting blood pressure, cholesterol, and blood sugar management. Phosphatidylserine (PS) promotes cognitive function, liver protection, and antioxidant activity, while Pyrroloquinoline Quinone (PQQ) provides antioxidant and mitochondrial support, helping to reduce fatigue and delay aging. Serine and L-Alanine, as essential amino acids, support metabolic regulation and liver health, making them popular in dietary supplements.
01
Functional Foods & Beverages
MCP, HM Pectin, and LM Pectin act as dietary fibers and natural gelling agents, improving gut health and post-meal blood sugar control, and are commonly used in jams, jellies, and meal replacement powders. PS and PQQ are added to functional drinks for brain support, energy boosting, and anti-fatigue effects, while L-Alanine is often included in liver support and hangover relief beverages.
02
Beauty & Personal Care
MCP and PQQ provide strong antioxidant and free radical scavenging effects, making them suitable for anti-aging and skin health products. PS helps reduce stress and regulate hormones, indirectly improving skin condition. HM and LM Pectin serve as natural moisturizers and thickeners, suitable for both topical skincare and oral beauty formulations.
03
Food Industry & Animal Nutrition
Natural Fermented Calcium Propionate functions as a natural preservative and calcium supplement, widely used in bakery, dairy products, and animal feed. HM and LM Pectin are used as gelling and stabilizing agents in the food industry. Serine and L-Alanine enhance metabolism and liver function in animals, supporting healthy growth and performance.
