Food freeze-drying technology

Water out. The fruit stays.

Freeze-drying removes water from a frozen ingredient under vacuum. The result is a dry, light, stable format that keeps shape, color and aroma — and that your operation can measure and dose.

Process

From fresh ingredient to operational format.

We are based in Jalisco, Mexico.

  1. Selection & prepFruit is received, selected, washed and cut at origin, under specification.
  2. FreezingWater in the fruit becomes ice.
  3. Primary dryingUnder vacuum, ice moves directly to vapor (sublimation). Structure is preserved.
  4. Secondary dryingResidual moisture is removed to the specification target.
  5. Format & packSlices, pieces, cubes or powder, packed to protect from moisture and oxygen.

Our freeze-drying

Industrial equipment. A controlled process.

Stainless-steel vacuum chambers in a clean area: fruit goes in on trays, is frozen and loses its water by sublimation down to the moisture on its specification sheet.

Two numbers that are not the same

Yield is not hydration.

Fresh equivalent

How much fresh goes in

A 20% yield for avocado means roughly 5 kg of fresh avocado is needed to produce 1 kg of powder. It is used to compare mass, freight and storage.

Hydration ratio

How much water your application takes

It is not derived from yield. It depends on the target texture, the recipe and the use, and it is set through formulation testing. That is why we don’t publish water ratios until they are validated with you.

Specifications

Every SKU, with its own specification sheet.

Shelf life, storage conditions and origin are confirmed per product and lot. We don’t apply one number to the whole portfolio.

Glossary

Freeze-drying (liofilización · lyophilisation)
Drying by freezing and vacuum sublimation. Spanish: liofilización; French: lyophilisation.
Sublimation
Ice turning directly into vapor without becoming liquid water. It is what preserves the food’s structure.
Yield
Freeze-dried mass ÷ fresh mass. It shows how much fresh produce is needed to make 1 kg of product.
Fresh equivalent
1 ÷ yield. Used to compare mass, freight and storage with the fresh ingredient.
Specification sheet
Per-SKU document with format, target moisture and water activity, microbiological parameters, validated shelf life, packaging and allergens.
