How Rapid Freezing Preserves Over 90% of Vitamin C in Frozen Blackberries

In the competitive world of food ingredients, quality isn’t just a feature—it’s your edge. For processors and buyers seeking premium frozen berries, understanding how rapid freezing technology preserves nutrients like vitamin C and antioxidants is essential. At Yishangqiao, we don’t just freeze blackberries—we lock in their natural power.

The Science Behind the Speed

Traditional slow-freezing methods cause large ice crystals to form inside fruit cells—damaging cell walls and releasing valuable compounds like vitamin C. In contrast, our rapid freezing process cools blackberries from room temperature to below -18°C within minutes. This minimizes crystal formation and keeps cellular structure intact.

According to a 2023 study published in the Journal of Food Engineering, rapid freezing can preserve up to 94% of ascorbic acid (vitamin C) in blackberries compared to only 67% with conventional methods. The same research showed a 20–30% higher retention of anthocyanins—key antioxidants responsible for color and health benefits.

Real-World Impact on Quality & Shelf Life

For food manufacturers, this means consistent flavor, texture, and nutritional value across batches—even after long-term storage. Our clients report fewer customer complaints about “flat” or “sour” frozen berry blends, thanks to better sensory stability.

“After switching to Yishangqiao’s rapid-frozen blackberries, our smoothie line saw a 15% increase in repeat orders from health-conscious consumers.” — Product Manager, North American Beverage Co.

This isn’t just lab data—it’s real-world performance. From cold chain logistics to shelf-ready packaging, every step in our supply chain is optimized for nutrient preservation, not just convenience.

Whether you’re sourcing for functional foods, bakery applications, or nutraceuticals, choosing the right frozen berry supplier makes all the difference. With over 90% of key nutrients retained, Yishangqiao delivers more than just frozen fruit—it delivers confidence in every ingredient.
