Fresh-cut fruit and vegetables are a staple of school nutrition programs—and one of the biggest sources of preventable food waste. You slice apples Monday morning, and by Monday afternoon they're brown. Students push them aside. Staff throw them out.
NatureSeal solves this. It's a produce treatment made from vitamins and minerals that prevents enzymatic browning for up to 14 days—without sulfites, preservatives, or flavor changes.
How Browning Happens
When you cut an apple or potato, enzymes (polyphenol oxidases) are exposed to oxygen, triggering browning within minutes. Traditional solutions have drawbacks:
- Citric acid / lemon juice: A few hours of protection, changes the flavor.
- Sulfites: Banned by the FDA on fresh fruits and vegetables.
- Ascorbic acid dips: Inconsistent and short-lived.
How NatureSeal Works
NatureSeal uses a blend of vitamins and minerals—primarily calcium and ascorbic acid derivatives—formulated to block browning at the cellular level. Dissolve the powder in water, dip your cut produce, and drain.
- 14 days of protection under refrigeration
- No flavor change—apples taste like apples
- No sulfites—GRAS rated by the FDA
- Vitamin fortification—treated produce gains a nutritional boost
What Produce Can You Treat?
- Apples — the most popular use case
- Pears and bananas
- Avocado and guacamole
- Lettuce and salad greens
- Potatoes, carrots, celery
Real-World Impact
A district serving fresh apple slices to 2,000 students per day can:
- Prep on Monday for the entire week. Apples served Friday look as fresh as Monday's.
- Reduce labor costs. One long prep session replaces five short ones.
- Cut waste 30–50%. Fresh-looking produce gets eaten, not trashed.
- Expand salad bar offerings. Pre-cut produce stays fresh for days.
