II. Product Introduction
1. Source
Naringin is refined through a meticulous process that includes impurity removal, pulverization, extraction, filtration, concentration, purification, and drying, using the peel of mandarins and aged tangerine peel—both key raw materials sourced from citrus plants of the Rutaceae family. This process effectively preserves the structural integrity and natural bioactivity of naringin. The raw materials undergo rigorous screening to remove impurities, adhering strictly to industry standards for plant extract processing. The product boasts a high purity level of 98%, making it suitable for a wide range of high-end application scenarios and ensuring consistent product quality and stability.
2. Core Efficacy and Applications
(1) The pharmaceutical field
Naringin (CAS: 481-53-8) exhibits relevant biological activities and holds considerable value in research on antioxidant, anti-inflammatory, and immune-modulating effects. It can be used as a pharmaceutical raw material in the development and production of related formulations. Any related applications must comply with pharmaceutical industry standards, clinical study findings, and national food safety regulations.
(2) The field of feed additives
As a natural active ingredient, naringin can be used as a feed additive in livestock, poultry, and aquaculture. Thanks to its anti-inflammatory, antioxidant, and digestive-promoting properties, it helps regulate the physiological functions of farmed animals and improve farming quality. This aligns with industry trends toward green and antibiotic-free farming. The use of naringin must comply with feed industry standards and follow the prescribed addition levels.
(3) Food Preservation Field
Naringin exhibits excellent antioxidant and antibacterial properties, making it suitable as a natural food preservative in food processing. It can delay food oxidation and spoilage, inhibit the growth of harmful microorganisms, and extend the shelf life of various foods, including fruits and vegetables, meat products, and baked goods. Naringin complies with industry standards for natural food additives.
