摘要： A food product containing microfibrillated cellulose is prepared by mixing together an edible liquid which swells cellulose, a food additive and fibrous cellulose to form a liquid suspension. The suspension is repeatedly passed through a small diameter orifice in which the mixture is subjected to a pressure drop of at least 3000 psig and a high velocity shearing action followed by a high velocity decelerating impact. The process converts the cellulose into microfibrillated cellulose and forms a stable homogeneous suspension of the microfibrillated cellulose, liquid and food additive.

摘要： Microfibrillated celluloses having properties distinguishable from all previously known celluloses, are produced by passing a liquid suspension of cellulose through a small diameter orifice in which the suspension is subjected to a pressure drop of at least 3000 psig and a high velocity shearing action followed by a high velocity decelerating impact, and repeating the passage of said suspension through the orifice until the cellulose suspension becomes a substantially stable suspension. The process converts the cellulose into microfibrillated cellulose without substantial chemical change of the cellulose starting material.
