Grupo Calidra, Graymont's new partner, is able to provide high purity hydrate to the food industry. Among the many industries using this food grade product are the tortilla and corn chip industries. All quality tortillas are treated with lime. Corn is first soaked in milk-of-lime before its conversion to cornmeal. Other lime uses in the food industry include:
- Dairy Industry
- Glue and Gelatin
- Baking Industry
- Fruits and Vegetables
An interesting market that Graymont participates in is the controlled atmospheric storage of fruit and vegetables. In this application, bags of hydrated lime are placed on racks in a storage room to absorb the carbon dioxide (CO2) that exudes from the ripening fresh produce. In this manner a higher ratio of oxygen to CO2 is maintained, permitting vegetables and fruit to be stored fresh for much longer periods. When placed in close proximity to the produce, the CO2 penetrates easily through the multiwall paper bags into the lime. For apples, lime consumption averages about 1 to 1.5 lb. /bushel. Pears, plums, and tomatoes, in addition to apples, have been stored in this way in Canada and the Northeastern U.S., as well as in Oregon and Washington. In California, this technique is commonly employed in storing lettuce.
