A clathrate of 1-methylcyclopropene with α-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.

Disclosed are methods and systems for inhibiting melanosis. The methods comprise the step of placing a melanosis-susceptible object, such as a crustacean or a vegetable, into a closable container or enclosure and exposing the object to aldehyde. In another aspect, disclosed are anti-melanosic articles and polymer compositions that incorporate tea (preferably green tea), matcha or epigallocatechin gallate (EGCG) that function as anti-melanosic agents by releasing aldehyde.

Described herein are systems and methods for ripening produce in a container during transit. The method includes maintaining, by a controller, an initial refrigerated climate in the container, detecting a first climate modification event, controlling automated vents in the container to an open state that exposes an interior of the container to an external environment until a temperature within the container increases to a predetermined temperature value, controlling, when the temperature reaches the predetermined temperature value, a ripening agent generator to inject a ripening agent into the container, continuously monitoring and controlling the ripening agent generator to maintain a target concentration of the ripening agent, detecting a second climate modification event, controlling the ripening agent generator to stop injecting the ripening agent, controlling a refrigeration unit to lower the container temperature to the initial refrigerated climate, and maintaining the initial refrigerated climate until arrival at a destination location.

The use of a palladium-doped zeolite for the adsorption of volatile organic compounds is described wherein the zeolite has a CHA framework type and is polymer-bound. Such zeolites have been found to have particular utility as packaging materials for the adsorption of volatile organic compounds, such as those originating from organic matter.

The invention discloses a food container for preserving freshness of food, comprising a container body having a cavity adapted for containing food items; a lid detachably secured on the container body to close the cavity of the container; and one or more food preserving elements capable of absorbing food spoiling gas to preserve freshness of the food items. The one or more food preserving elements are disposed inside the cavity and/or into a material of the food container to preserve the food items for an extended period of time and remove odors.

A food preservation system is provided. The system includes a storage cabinet for storing foods, an electrolytic gas generator, a gas sensor and a control unit. The electrolytic gas generator is in fluid communication with the storage cabinet to output a first gas and a second gas to preserve the foods. The gas sensor is arranged in the storage cabinet to detect the concentration of the gases in the storage cabinet for obtaining gas concentration information which includes a first gas concentration and a second gas concentration. The control unit is electrically connected to the electrolytic gas generator and the gas sensor. According to the received gas concentration information, the control unit adjusts the applied voltage of the electrolytic gas generator to control the gas species generated by the electrolytic gas generator and the first and second gas concentrations in the storage cabinet.
