METHOD FOR FOAMING FOOD BY USING NITROUS OXIDE AS FOAMING AGENT

摘要

A container (1) containing a foaming-target food is charged at a predetermined pressure with nitrous oxide and a gas having a smaller solubility in the food than nitrous oxide. Then, the container (1) is shaken sufficiently, and a lever (3c) is operated to let the food come out, whereby the gas in the food begins foaming to give a foamed food product in which fine cells distribute uniformly.
