I. Basic Information
Product Name : White Pepper Extract
Plant Source : Piper nigrum L.
Medicinal Part : Mature pepper fruits are soaked and the outer skin is removed to obtain white pepper. This is used as raw material to extract PMC (black pepper is made from unripe fruits dried with the skin on, and the raw material processing techniques are different)
Alternative Names : White Pepper Extract, White Pepper Oil Resin (liquid type
Core Indicator Component : Piperine(determines spiciness and biological activity)
Piperine
CAS: 94-62-2
Molecular formula: \(\boldsymbol{C_{17}H_{19}NO ₃}\)
Molecular weight: 285.34
Appearance: Pale yellow crystals
Solubility: Lipid-soluble, almost insoluble in cold water, readily soluble in ethanol, acetone, and oils
Ii. Chemical Composition
1.Piperamide alkaloids (main activity) : Piperine is the main component, and it also contains piperidine, piperine, etc. The volatile oil content of white pepper raw materials is lower than that of black pepper, but the purity of piperine is relatively clean and it has less off-flavors. Pharmaceutical practice and…
2. Volatile Oils (terpenoids) : Limonene, β -caryophyllene, pinene, etc., provide aroma
3. Others: Phenols, organic acids, a small amount of polysaccharides, minerals
Iii. Extraction Process and Product Specifications
Extraction method
1. Ethanol reflux extraction : Most commonly used, obtaining powder extract; Suitable as raw materials for health products
2. Supercritical CO₂ extraction: Low temperature, aroma retention, mostly used for pepper oil resin (viscous liquid, rich flavor)
>
Oil resin: Concentrated flavoring compound, with a spiciness and aroma dozens of times that of original pepper powder, directly used for food seasoning
Mainstream specifications on the market (HPLC detection)
1. Proportion extract: 10:1(Extract 10kg of raw materials to obtain 1kg of extract, total extract, not labeled piperine)
2. Standardized piperine specifications: 5%, 10%, 95%, 98%** (The most commonly used 95%/98% piperine in health products)
Appearance
- Powder: Light yellow to grayish white fine powder
- Oil resin: Yellowish-brown viscous oily liquid
Iv. Core Biological Functions
1.Biological enhancer (the most core commercial value)
Piperine can inhibit intestinal CYP metabolic enzymes and P-glycoprotein excretion transporters, significantly enhancing the bioavailability of liposoluble active substances. The most classic combination: Curcumin + piperine , significantly increasing the blood concentration of curcumin; It can also enhance the absorption of puerarin, carotene and other substances. This mechanism also affects the metabolism of some prescription drugs. Pharmaceutical Practice and…
2. Promoting digestion : Stimulating the secretion of saliva and gastric juice; Relaxes the smooth muscles of the gastrointestinal tract and is traditionally used for cold stomach, loss of appetite and abdominal distension.
3. Antioxidant and anti-inflammatory : In vitro and animal experiments have shown that it can eliminate free radicals and inhibit the expression of inflammatory factors.
4. Antibacterial : It has an inhibitory effect on some food spoilage bacteria and can be used as an auxiliary raw material for natural food preservation.
5. Metabolic Regulation : Animal studies have shown that it can regulate lipid and sugar metabolism. This is only basic research and does not have therapeutic effects
V. Application Fields：
1：Dietary supplements (the largest market)
2：Food Industry (mainly oil resin)
3：Cosmetics
4：Feed, flavors and fragrances, etc. (Secondary uses)
