In addition to Mantrose products, our NatureSeal division continues to grow rapidly by developing high quality formulations to keep cut produce fresh. What started with a CRADA with the USDA-ARS has grown into a full product line of fresh cut solutions. From keeping guacamole fresh and vibrant to ensuring sliced apples don’t lose their succulent-crisp appearance, NatureSeal offers formulations that treat a vast variety of sliced produce. Our UK subsidiary, Agricoat NatureSeal Ltd offers natural edible coatings for pre-harvest as well as post-harvest and are designed to effectively extend the storage and shelf-life of whole fruits and vegetables.
