Sweet Tea Extract is refined from fresh leaves of Rubus Suavissimus via low-temperature extraction, purification and spray drying technology.

Sweet Tea Extract core active ingredient is rubusoside, along with flavonoids, polyphenols and vitamins.

Sweet Tea Extract delivers intense natural sweetness with zero calories, no bitter aftertaste, excellent heat resistance and good water solubility. It contains no artificial sweeteners, preservatives or harmful impurities.

The health benefits of sweet tea extract are primarily attributed to its active ingredients, including rubusoside (sweet tea glycoside), tea polyphenols, and flavonoids.

• Regulating Blood Sugar and Lipids:
  • Lowering Blood Sugar: Studies show that rubusoside can significantly reduce blood sugar levels in diabetic models and improve glucose tolerance.
  • Lowering Blood Lipids: Rubusoside also positively reduces serum triglycerides and cholesterol while increasing beneficial high-density lipoprotein cholesterol (HDL-C) levels.

• Antioxidant and Anti-inflammatory Effects:
  • Flavonoids and tea polyphenols in sweet tea possess strong antioxidant capabilities, effectively scavenging free radicals. Some research indicates its flavonoid antioxidant efficacy may surpass certain synthetic antioxidants like BHT.
  • The extract can also inhibit the production of inflammatory factors, showing clear effects in alleviating swelling and other inflammatory responses.
• Anti-Allergic Effects:
  • Sweet tea extract has been proven effective in inhibiting various allergic reactions, such as passive cutaneous anaphylaxis and bronchospasm, leading to its use in developing anti-allergic health foods.
• Protecting Teeth and Oral Health:
  • Rubusoside can inhibit the activity and adhesion of Streptococcus mutans, which causes dental caries, making it a natural anti-cariogenic sweetener.
• Other Potential Benefits:
  • Traditionally, sweet tea is used for relieving cough and reducing phlegm.
  • Some studies suggest potential in anti-tumor effects, regulating gastrointestinal function (e.g., inhibiting excessive small intestine movement), and enhancing immunity.

Based on the above efficacy, sweet tea extract finds utility in various industries.

• Food and Beverage Industry:
  • With a sweetness 200-300 times that of sucrose and very low calories, rubusoside is an ideal natural sugar substitute widely used in beverages, pastries, candies, and yogurt.
  • Components like tea polyphenols can also serve as natural antioxidants to extend food shelf life.
• Pharmaceuticals and Health Products:
  • Leveraging its blood sugar-lowering, lipid-lowering, and anti-allergic properties, sweet tea extract is developed into various health products to assist in managing blood sugar, lipids, and allergies.
  • Its traditional effects, like clearing heat, moistening the lungs, relieving cough, and soothing the throat, also incorporate it into some herbal formulations.
• Personal Care and Daily Chemical Products:
  • In toothpaste, mouthwash, and other oral care products, sweet tea extract functions to prevent dental caries and maintain oral health.
  • Its anti-inflammatory and antioxidant properties also make it a potential ingredient in cosmetics.
• Agriculture and Other Fields:
  • Research explores using sweet tea polyphenols as natural antibacterial agents for food preservation to inhibit harmful bacteria.
