The Latin name for goji berry extract is Lycium barbarum L., appearing as a brownish-yellow powder. Its primary components are goji polysaccharides and betaine.
Lycium barbarum polysaccharides are water-soluble polysaccharides. These polysaccharides have been identified as proteoglycans with a molecular weight of 22–25 kDa. They consist of six monosaccharides: arabinose, glucose, galactose, mannose, xylose, and rhamnose, with a content of 20% and 50% (UV).Light yellow powder, hygroscopic. Water solubility: Soluble in water, no precipitation. Heavy metal content: As < 1.0 ppm, Cd < 2 ppm, Cr < 1 ppm, Pb < 2 ppm, Hg < 0.5 ppm. Sanitary standards: Bacterial count < 1000 CFU/g, E. coli and live mites not detectable, Mold count < 100 CFU/g. Loss on drying: ≤ 9%.
Betaine Molecular formula: C5H11NO2 Molecular weight: 117.15 CAS: 107-43-7 Melting point: 301°C Water solubility: 160g/100mL Properties: Pure betaine is a white hygroscopic crystalline substance, neutral, with good stability and flowability.Betaine hydrochloride is a white hygroscopic powder or crystal with pH=0.8–1.2. 40% betaine powder is pale yellow, neutral, low hygroscopicity, with good stability and flowability.
Goji berries are the fruit of Lycium barbarum L., a plant of the Solanaceae family.Harvested in summer and autumn when the fruit turns orange-red. Air-dry until the skin wrinkles, then sun-dry until the outer skin is dry and hard while the pulp remains soft. Remove the pedicels. Characteristics: The fruit is ellipsoidal, 6–18 mm long and 6–8 mm in diameter. The surface is bright red or dark red with irregular wrinkles and a slight sheen. The apex bears a stigma scar, and the opposite end has a pedicel scar.Texture: Soft and moist, with thick, sticky pulp containing 25–50 seeds. Seeds are flat-kidney-shaped, up to 2.5 mm long and 2 mm wide, light brown in color. Odor faint; taste sweet with slight acidity. Main components: Lycium polysaccharides, betaine, zeaxanthin, carotene, amino acids, etc.
