A device for the preparation of foods includes a container having a bottom and a lateral surface, a grid adapted to be removably placed into the container, a cover for closing the container with the grid therein. A presser is coupled to the cover for pressing a content in the container, an adjustment device is configured for adjusting the insertion of the presser in the container.

A clathrate of 1-methylcyclopropene with -cyclodextrin, obtained as a solid particulate product, is modified by comminuting, classifying, or both to obtain a modified particulate. When subjected to identical atmospheric disgorgement conditions of humidity and temperature, identical masses of the modified and unmodified particulates exhibit different rates of 1-methylcyclopropene disgorgement. Specifically, we have found that a smaller mean particle size is inversely related to a greater rate of 1-methylcyclopropene release.
