Reb M contains three β-D-glucosyl units (vs two in Reb A/D) with 1→2 and 1→6 linkages at C-13/C-19 positions. This triple-glycosylation gives it 500-550× sucrose sweetness (vs 350× for Reb A) and reduces bitterness threshold to ≤0.15ppm.

Reb M's higher molecular weight (1287.4 g/mol vs 967.0 for Reb A) necessitates: ethanol-water ratio of 55:45 (vs 65:35 for Reb A), prolonged nucleation phase (120min vs 60min), and strict temperature control at 40±0.5°C to achieve ≥98% purity crystals.

Reb M demonstrates exceptional stability with only 3.2% degradation at 180°C for 30min (vs 8.5% for Reb D, 15% for Reb A). Its degradation activation energy (Ea=102.5 kJ/mol) is 23% higher than Reb A, making it ideal for baking applications.

Sample preparation requires 2mL extraction with methanol/water (7:3) at 80°C for 30min. HPLC analysis follows GB1886.355-2022 Annex A with detection limit of 100mg/kg. Calibration range is 200-1000mg/L for accurate quantification

Reb M shows 12g/L solubility in water (25°C), increasing to 85g/L in 40% ethanol. In oil-in-water emulsions, its partition coefficient (log P=-1.3) ensures 92% remains in aqueous phase, making it ideal for beverages and dressings.

According to GB1886.355-2022, use C18 column (4.6×150mm, 5μm) with 0.8mL/min flow rate and 210nm detection wavelength. The mobile phase requires 25-45% acetonitrile gradient in 0.1% phosphoric acid for baseline separation[2][6].

Reb M is used in tablets, protein powders, and pet foods due to zero-calorie property and clean taste. It masks bitter flavors in medicines while meeting GB1886.355-2022 safety standards for pharmaceutical excipients.

Reb M's superior taste profile (no bitter aftertaste) makes it ideal for premium drinks. It's 500x sweeter than sucrose with clean flavor, complying with GB1886.355-2022 for beverage additives (usage level 100-500mg/L)[1][2].

Sinopure controls 10,000 acres of stevia farms across China, yielding 5,000 tons dried leaves/year. Leaves must be processed within 8hrs after harvest with moisture ≤10% to maintain glycoside content per GB1886.355-2022.

Reb M provides clean sweetness without bitter aftertaste, making it perfect for high-end beverages. With 500× sucrose sweetness intensity and excellent stability in acidic conditions, it outperforms other sweeteners in clarity and taste profile .

Sinopure utilizes a five-stage membrane separation system combined with continuous chromatography to produce 200 tons/year of high-purity Reb M (≥98%). The process achieves 92% recovery rate while maintaining strict GB1886.355-2022 standards.

With zero calories and excellent stability (≤3.2% degradation at 180°C), Reb M effectively masks bitter drug flavors in tablets and protein powders while meeting GB1886.355-2022 pharmaceutical excipient requirements.

GB1886.355-2022 specifies 80°C extraction for 30 minutes using methanol/water (7:3 v/v) solution for optimal recovery. HPLC analysis requires column temperature at 40°C with 0.8mL/min flow rate for accurate quantification

Sinopure controls 10,000 acres of stevia farms in China (Anhui, Henan, Jiangsu, Gansu), producing 5,000 tons of premium dried leaves annually. Leaves are processed within 8 hours of harvest with moisture ≤10% to maintain glycoside content .

GB1886.355-2022 specifies calibration using 100-1000mg/L standards for routine analysis, with detection limit of 100mg/kg. Sample injection volume is 2-10μL using C18 column (4.6×150mm, 5μm) at 210nm detection.
