Stv Series – Natural Sweetener Solutions

What are key quality specifications for food-grade STV?

JECFA & FCC standards require: ≤1.0% moisture, ≤0.1% sulfated ash, ≤2.0% residue on ignition, lead ≤1mg/kg, arsenic ≤3mg/kg, microbial counts

What is Sinopure’s production capacity for STV products?

Sinopure has an annual production capacity of 200 tons for high-purity steviol glycosides including STV, utilizing advanced five-stage membrane separation and continuous chromatographic purification systems . The company controls over 10,000 acres of stevia plantations producing 5,000 tons of premium dried leaves annually.

What are the industrial uses of STV in China?

In China, STV is widely used as semi-finished product for further processing in preserved fruits (particularly in candied plums and melon seeds) due to its high stability and clean taste profile . It's also applied in bakery, dairy products, and premium beverages.

What quality certifications does Sinopure hold for STV production?

Sinopure maintains FDA GRAS, Organic, ISO9001, ISO22000, FSSC22000, HALAL, and KOSHER certifications for its steviol glycoside products including STV . The company implements integrated quality systems meeting international standards for food additives .

What’s the standard testing method for STV purity?

Our specifies HPLC analysis using C18 column (250mm length, 0.25mm diameter, 0.25μm particle size) with mobile phase flow rate at 5.0mL/min and detection at 210nm. Sample preparation requires 80°C extraction for 30 minutes.

What are the global ADI limits for STV consumption?

JECFA/WHO established an ADI of 4mg steviol equivalents/kg bw/day (equivalent to ~12mg STV/kg). This translates to approximately 720mg STV for a 60kg adult. Notably, STV has 90%+ renal excretion within 24 hours (clinical studies) and shows no mutagenicity (AMES test negative) at 5000μg/plate [1][4]. Our products carry usage guidelines compliant with all major markets including FDA GRAS and EU.

What’s the standard HPLC method for STV quantification?

According to JECFA and ISO 21253-1:2019, analysis requires C18 column (4.6×250mm, 5μm) with acetonitrile/water (32:68) mobile phase at 1.0mL/min, 210nm detection. Retention times are: Stevioside (6.5min), Reb A (8.2min), Reb C (10.1min).

How do STV sweetness levels compare to sugar?

STV sweetness ranges from 200-350× sucrose depending on glycoside composition. Reb A is 200-250×, Stevioside 250-300×, and purified Reb D/M can reach 350-450×. Blends are typically formulated to match sucrose's temporal profile.

What are STV’s thermal stability characteristics?

STV remains stable up to 200°C with ≤5% degradation after 1 hour. In acidic conditions (pH 3), solutions maintain >95% integrity after 6 months at 25°C. Degradation follows first-order kinetics with Ea=62.4 kJ/mol between 100-200°C.
