A method for manufacturing an instant egg/edible bird's nest soup with fermented glutinous rice, comprising the steps of preparing the fermented glutinous rice wine, separating the wine juice from the rice dregs, preparing the dehydrated egg droppings/edible bird's nest shreds, vacuum freeze drying and vacuum packing; the instant egg/edible bird's-nest soup with fermented glutinous rice manufactured according to the method of the present invention is easily portable, and can be immediately consumed after being brewed in hot water; the flavor of the brewed egg/edible bird's nest soup with fermented glutinous rice is fresh and sweet; the shape of the rice dregs and the egg droppings/edible bird's nest shreds can be perfectly kept, and the rice dregs and egg droppings/edible bird's nest shreds are soft and good-tasting.

A method of freezing and preserving a frozen object includes: controlling a temperature in a container to keep the temperature at a predetermined freezing temperature and applying an AC voltage to the frozen object such that a weak current (1 A or more and 1,000 mA or less) flows through the frozen object in the container; and while applying the AC voltage to the frozen object in the container, freezing and preserving the frozen object at a predetermined freezing temperature for a predetermined preserved period or more.

A method of providing sushi for consumption. The method includes preparing the sushi; placing the sushi in a humidified refrigerated storage unit at an ambient humidity level over 65% and under 99% and at a temperature between about 0 C. and about 7 C.; preserving for a period under fifteen hours the sushi in the humidified refrigerated storage unit to reduce loss of moisture of the sushi rice of the sushi during the preservation period; and removing the sushi from the humidified refrigerated storage unit prior to being served.

A refrigerator comprises a refrigerator body, an air-conditioning membrane assembly and an air pump assembly. The refrigerator body defines a storage space and a compressor chamber therein, a storage container is arranged in the storage space, and a freshness-keeping space is defined inside the storage container. The air-conditioning membrane assembly is configured to allow more oxygen than nitrogen in airflow in a surrounding space of the air-conditioning membrane assembly to pass through the air-conditioning membrane and enter an oxygen-rich gas collection chamber. An inlet end of the air pump is communicated with the oxygen-rich gas collection chamber in a controlled manner via a pipeline and a pipeline switching mechanism, for pumping gas in the oxygen-rich gas collection chamber to the outside of the freshness-keeping space, such that the actual content of oxygen in the freshness-keeping space is in a range of 2% to 19%.

The insulated container having an internal support to separate ice, food, and drinks from melted ice water or liquids to prevent damage to the dry items. The dry items are placed on top of the flat upper surface of the removable support. The removable support may include apertures that allow melting ice water to drain past the top surface and through the apertures of the removable support.

The present invention, in an embodiment thereof, provides a latent heat storage material containing a supercooling inhibitor that, if added to an aqueous solution of an inorganic salt including sodium chloride, restrains supercooling by unfailingly precipitating as crystals upon cooling and therefore only marginally lowers the melting point and reduces latent heat. The latent heat storage material contains: an aqueous solution of sodium chloride; and a eutectic aqueous solution of sodium chloride and disodium hydrogen phosphate in an amount that, in comparison with the eutectic aqueous solution of sodium chloride, is greater than or equal to an amount that gives a saturation concentration at 0 C. This arrangement makes a sufficient amount of latent heat available for cooling white restraining supercooling, by using a latent heat storage material containing a supercooling inhibitor that restrains supercooling by unfailingly precipitating as crystals upon cooling and that therefore only marginally lowers the melting point and reduces latent heat.

A system and methodology for rehydrating perishable items (e.g., flowers, fresh food items, such as fruits, vegetables, other produce, and nuts) during storage and transportation thereof. The osmotic rehydration apparatus includes a pressurized chamber, a humidifier, an ozone generator, an electrostatic sprayer, a reservoir containing saline, and an air compressor. The perishable items are placed in the osmotic chamber under positive pressure. A film of saline solution is applied to the surface of the perishable items via an electrostatic sprayer. The saline/chlorine film on the perishable items is dried, and the osmotic chamber is saturated with ozone gas via an ozone generator. The osmotic chamber is then saturated with tiny pure water droplets via a humidifier or an electrostatic sprayer. The pressure within the chamber is raised to a pressure above atmospheric pressure. The osmotic chamber is then placed inside a cooler at a temperature slightly above freezing.

A system, apparatus, and method of storing food including a storage container having a base; a resilient liner nesting in the base, and a lid that interlockingly engages with the liner and/or base to close off access to foodstuffs retained in a compartment defined by the liner. A valve assembly in the lid is actuated by a pump to evacuate air from the liner's compartment and create a vacuum or near-vacuum condition therein. Apertures defined in the wall of the base allow air to flow into a compartment of the base as the resilient liner shrinks around the food. The closed storage container may be placed in a freezer to freeze the food therein. For defrosting, the base of the closed storage container is placed in a volume of water, some of which flows through the apertures in the base's wall and comes into direct contact with the liner.
