Product Description

Chicken gizzard membrane powder, named for its golden medicinal value, is a powdered product made from the dried inner lining of the gizzard of domestic chickens (Gallus gallus domesticus Brisson). With over a thousand years of documented use in traditional Chinese medicine, modern processing techniques have revitalized this traditional ingredient, transforming it into an important functional material for food, health products, and pharmaceuticals.

Key Nutritional Components

Digestive Enzymes: Although containing minimal pepsin and amylase, it stimulates gastric secretion and enhances stomach motility.

Proteins & Peptides: Rich in keratin and other proteins; enzymatic hydrolysis yields highly absorbable oligopeptides.

Functional Compounds:

Gastrin-like substances (promote digestion)

Ammonium chloride (aids detoxification)

Selenium and trace minerals

Polysaccharides: Shown to regulate blood sugar and lipids.

Vitamins: Contains B-complex vitamins.

Quality Control

Sensory: Uniform color, no clumping, mild odor.

Physicochemical: Moisture ≤5%, pH ~6, sieve pass rate ≥95% (80 mesh).

Activity Testing: Gastrin-like substances, peptide content.

Safety: Complies with microbial and heavy metal standards.

Technical Analysis

Digestive System Effects

Gastric Secretion: Oral intake (5g) increases gastric juice volume by 30–37% within 45–60 minutes.

Acidity Enhancement: Free acid increases by 32–113%, total acidity by 25–75%.

Gastric Motility: Prolongs gastric movement and accelerates emptying.

Detoxification & Antioxidant Properties

Radionuclide Excretion: Water decoctions accelerate strontium elimination (2–3x higher urinary excretion).

Antioxidant Activity: Selenium and polysaccharides enhance cellular defense.

Potential Anti-Tumor Effects

Preliminary in vitro studies show tumor cell inhibition.
