Q1: What is the difference between food-grade and vape-grade flavor concentrates?
A:While both are generally safe for ingestion, vape-grade flavor concentrates are specifically formulated to ensure thermal stability, purity, and compatibility with e-liquid bases (PG/VG/nicotine). Food flavors may contain oils or additives unsuitable for inhalation.

Q2: Can I use the same flavor concentrate for nicotine and nicotine-free e-liquids?
A:Not always. Some flavor molecules may interact with nicotine, causing flavor shifts or discoloration. Vape-grade concentrates from Guangdong Unique Flavor Co., Ltd. are tested for nicotine compatibility.

Q3: What causes e-liquid flavors to fade over time?
A:Flavor fade may result from oxidation, volatile loss, or chemical interactions with nicotine or container materials. Proper storage and use of stabilized flavor concentrates can slow down this process.

Q4: Are your flavors heat-stable for sub-ohm vaping?
A:Yes. Our vape-grade concentrates are designed to withstand high-temperature vaporization (above 200°C), minimizing thermal degradation of key aroma compounds.

Q5: How to select the right fruity flavor for high-VG formulations?
A:Choose highly concentrated, low-viscosity flavors with enhanced diffusion. Our "ProFruit Series" is optimized for VG-heavy e-liquids with stronger vapor-phase performance.

Q6: Are your flavor concentrates diacetyl-free?
A:Yes. All flavor concentrates comply with international safety standards and are rigorously tested to be diacetyl-free. COAs and safety data sheets are available upon request.

Q7: Why does my e-liquid taste burnt after a few puffs?
A:This may result from poor wick saturation, coil overheating, or use of unstable flavor compounds. Choosing high-temperature-stable concentrates helps prevent flavor breakdown.

Q8: Can you customize flavor concentrates for specific market trends?
A:Absolutely. Our R&D team closely tracks global trends and offers custom flavor development services for tropical, dessert, herbal, or regional profiles.

Q9: How do you ensure consistency in every batch?
A:We employ standardized raw material sourcing, automated proportioning systems, and GC-MS quality checks to ensure every batch delivers consistent aroma and strength.
