With a conventional method of causing impregnation of a liquid
seasoning into food, it takes many hours for the liquid
seasoning to substantially make
permeation. Occasionally, impregnation was not at all attained. Such proposals have been made that food soaked in a liquid
seasoning is pressurized, or that
water content of food is dehydrated. An apparatus and a facility for carrying out
processing to food need to be larger in size, thereby taking cost and being not suitable for
mass production. Also, uniform
permeation of the liquid seasoning in a short time was not achieved.The present invention provides a liquid seasoning used for seasoning food subjected to
processing with a micro-nano bubble generating device, thereby enabling the liquid seasoning to have impregnation to food in a short time, particularly, facilitating impregnation of good
flavor and taste compositions other than salt. Moreover, providing the
processing to the liquid seasoning enables the apparatus and equipment to be simple in comparison with the conventional art applying processes to food, resulting in cost reduced and energy-saving.food
