Q: Why is calcium ascorbate a better choice than regular ascorbic acid in food applications?
A: Unlike acidic ascorbic acid, calcium ascorbate is pH-neutral (6.0–8.0), making it ideal for sensitive formulations like dairy or infant nutrition. It also provides bioavailable calcium (10–12%) alongside Vitamin C’s antioxidant benefits.
Q: How does your 98% purity compare to competitors?
A: Renze’s lab-tested ≥98% assay ensures superior potency and compliance with USP/FCC standards, while competitors often range at 95–97%. Our low heavy metal limits (<10ppm Pb) further guarantee safety.
2. Application-Specific Insights
Q: Can this powder be used in effervescent tablets without reactivity issues?
A: Yes! Calcium ascorbate’s non-acidic nature reduces fizzing instability, unlike ascorbic acid. Pair it with sodium bicarbonate for optimal effervescence.
Q: What’s the recommended dosage for meat preservation?
A: Trials show 0.1–0.5% by weight effectively inhibits lipid oxidation in meats, extending shelf life while meeting FDA/EFSA limits for antioxidants.
3. Supply Chain & Compliance
Q: Is this product certified for global markets?
A: Renze’s powder meets USP, FCC, and EU food-grade standards (E302). Custom documentation (COA, TDS) is available for export compliance.
Q: What’s the MOQ and lead time for bulk orders?
A: MOQ starts at 25kg, with lead times of 10–15 days. We offer flexible packaging (25kg drums or custom retail sizes) and logistic support.
4. Scientific Differentiation
Q: How does calcium ascorbate enhance bioavailability vs. synthetic Vitamin C?
A: The calcium bond improves intestinal absorption rates by ~20% (per J. Nutr. Sci studies), especially in low-iron diets.
Q: Does heat processing degrade its potency?
A: Our tests show ≤5% activity loss at 150°C/10min, outperforming standard ascorbic acid (15–20% loss), ideal for baked goods.
5. Troubleshooting
Q: The powder turned slightly yellow—is it still safe?
A: Mild yellowing is natural oxidation but doesn’t affect functionality. Store in airtight containers below 25°C to maintain whiteness.
Q: Can I blend it with other antioxidants like Vitamin E?
A: Absolutely! Synergistic effects are documented—e.g., 1:1 ascorbate + tocopherol boosts radical scavenging by 30%
