Jasmine (e.g., Jasminum sambac, Jasminum officinale) is a highly prized flower renowned for its intense, delicate fragrance (derived from volatile aromatic oils like linalool and jasmone) and bioactive components (flavonoids, phenolics). Vacuum Microwave Drying (VMD)—a technology that merges microwave volumetric heating with a low-pressure vacuum environment—solves the critical limitations of traditional jasmine drying methods (e.g., hot air, sun drying), such as severe aroma loss, petal browning, and nutrient degradation.
VMD-dried jasmine retains exceptional aroma, color, and nutritional value, making it ideal for high-value applications:
Food & Beverage: The primary use is jasmine tea (blended with green/black tea to infuse fragrance). It is also added to pastries (jasmine cakes), beverages (jasmine sparkling water, milk tea), and desserts (jasmine pudding) for a delicate floral note.
Cosmetics & Aromatherapy: Recovered aromatic oils are used in perfumes, lotions, facial masks, and candles. Dried jasmine powder (ground petals) is added to skincare products for its antioxidant and soothing properties (beneficial for sensitive skin).
Traditional Medicine (TCM): Used to soothe the nerves, relieve anxiety, and clear heat. Processed into herbal teas, tinctures, or sachets (superior to hot air-dried jasmine for medicinal efficacy).
Ornamental & Craft: Intact VMD-dried jasmine is used in flower arrangements, resin crafts, wedding decorations, or scented sachets (retains color and faint fragrance for 6 ~ 10 months).
Jasmine flower oil: The jasmine flower cell liquid collected in the condenser, after oil-water separation, can yield high-purity rose essential oil.
In summary, vacuum microwave drying is a revolutionary technology for jasmine processing. By combining efficient microwave heating with a protective vacuum environment, it maximizes the retention of jasmine’s signature fragrance, delicate color, and bioactive components—while drastically reducing drying time and energy costs. This technology has become the gold standard for high-quality jasmine products in the tea, cosmetic, and aromatic industries, replacing traditional methods due to its unmatched performance.
