❓ "What's the optimal dosage for bread dough strengthening?"
→ Recommended usage:
• 50-75ppm (based on flour weight)
• Increases dough elasticity by 30-40%
• Improves loaf volume by 20-25%
• Best added during first mixing stage
❓ "Can it replace potassium bromate in bread making?"
→ Clean-label conversion:
✔ 75ppm ascorbic acid + 0.1% enzyme blend
✔ Provides comparable dough strengthening
✔ No residual chemical concerns
❓ "How to prevent browning in fresh juices?"
→ Effective protocol:
• 0.03-0.05% ascorbic acid
• Combined with 0.01% citric acid (pH adjustment)
• Reduces browning by 80-90% for 7-10 days
❓ "Does ascorbic acid affect beverage flavor?"
→ Flavor impact analysis:
• ≤0.05%: No detectable taste
• 0.05-0.1%: Slight tartness (beneficial in citrus drinks)
• >0.1%: Requires flavor masking
