Method for imparting a foedemiddel, based on raw materials consisting of minced fish or meat, a porous structure

摘要

A porous food product is prepared by mixing sodium alginate and a calcium compound with ground fish or meat, heating the mixture, introducing a pressurized gas and an acid into the mixture, the acid liberating calcium ions from the calcium compound to cause the sodium alginate to form a gel which confers a porous structure on the product, and reducing the pressure to liberate gas and form gas bubbles in the product.
