A method of making a porous, dehydrated food product comprises subjecting a food product to pulsed electric field treatment to form pores in the cell membranes of the food product, freezing the treated food product, and exposing the treated frozen food product to microwave radiation in a vacuum chamber at a pressure that is less than atmospheric and at which the boiling point of water is above 0 C., causing the frozen food product to thaw and water to evaporate to produce the porous, dehydrated product. The process is faster than freeze-drying and consumes less energy. The pulsed electric field treatment does not result in structural damage to the product, despite the thawing of the frozen product during the drying process.

A frozen sushi pack includes: a container; and a plurality of sushi pieces arranged in the container. Each of the sushi pieces includes: a shari rice base; and a neta topping. Using a water content per unit volume ranging from 55% to 65% as a reference value, the sushi pieces in the container are classified into: first sushi pieces of a first group in which the neta topping contains a water content below the reference value; and second sushi pieces of a second group in which the neta topping contains a water content equal to the reference value or above.

The disclosure relates to an Ice maker. Specifically, the disclosure relates to an ice maker having a circulating coolant fluid that is separate and distinct from the circulating refrigerant used to control the coolant's temperature in a hot coolant reservoir and a cold coolant reservoir.

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.
