Frequently Asked Questions

Q1. Is the purple color natural?

Yes, completely natural. The vivid deep purple color comes from anthocyanin pigments naturally present in purple sweet potato flesh — no artificial coloring is used. The intense purple is preserved by our low-temperature VF process.

Q2. What is VF (Vacuum Frying) technology?

Vacuum Frying is a low-temperature frying technology that processes vegetable sticks under vacuum conditions at temperatures much lower than conventional deep frying. This preserves the natural color, anthocyanins and nutrients while delivering a light crispy texture — essential for retaining the iconic deep purple color.

Q3. What is the difference between purple sweet potato and taro?

Purple sweet potato has uniformly deep purple flesh and a naturally sweet caramel-like flavor — closer to regular sweet potato but with bold purple color and higher anthocyanin content. Taro has cream-colored flesh with purple veining and a distinctive nutty aromatic flavor. Both make excellent VF chips for different applications and visual profiles.

Q4. What are anthocyanins and why do they matter?

Anthocyanins are powerful natural antioxidants that give purple sweet potato its deep color. They are recognized in nutrition science for supporting cellular health and free radical defense. Purple sweet potato is one of the most concentrated natural sources of dietary anthocyanins.

Q5. What is the difference between VF and conventional fried sweet potato sticks?

Conventional high-temperature frying would fade the deep purple color into brown, destroy heat-sensitive anthocyanins and create a heavy oily mouthfeel. VF uses low-temperature vacuum frying, preserving the vivid purple color, antioxidant content and crispy texture.

Q6. What type of oil is used in the frying process?

We use food-grade vegetable oil (typically palm or sunflower oil) certified for food production. The vacuum frying process uses oil at much lower temperatures than conventional frying, resulting in a cleaner finished product. Specific oil type can be confirmed based on your market requirements.

Q7. Can purple sweet potato sticks be combined with other vegetable chips?

Absolutely. The vivid purple color makes it a visual highlight in any mixed veggie chip blend, pairing beautifully with orange carrot, cream lotus root, golden pumpkin and green snap peas. It instantly elevates the visual richness and superfood appeal of mixed packs.

Q8. Can you provide OEM and private label service?

Yes. We offer full OEM service including stick length and thickness customization, seasoning options, custom packaging design, your brand logo, nutrition label printing and multilingual packaging for different markets.

Q9. What is your MOQ?

MOQ depends on the packaging type and specifications. Please contact us with your detailed requirements for an accurate quotation.

Q10. What is the shelf life and how should it be stored?

Shelf life is 12 to 18 months when stored in a cool, dry place away from direct sunlight. Once opened, please reseal tightly and consume within a short period to maintain crispness and prevent oil oxidation.
