Title: Protein emulsion stable in presence of salt, by treating soya protein - used in chopped meat foods pref. sausages
IPC: A23L11/30
Filed: 1975-11-28
Abstract: A protein emulsion stable in the presence of salt is prepd. by (a) a suspension of isolated soya protein is formed with a pH 5.7-8, and a solids content is not >15%, (b) the suspension is heated dynamically under a positive pressur to >71 degrees C and kept under a positive pressure for at least a few seconds, (c) the pressure is released to give a rapid volatilisation by expansion of moisture contg. undesired flavour and taste constituents, (d) the suspension is dried at 116 degrees C, and (e) the product is emulsified with water, salt and fatty material. In another process between stages (c) and (d) an edible reducing agent is added in quantity >=0.1% (based on the suspension solids). The product is used to prepare chopped meat products such as sausages. Previous soya products have either been unsuitable for making an emulsion stable on the presence of salt or such a large amount had to be used which rendered the price prohibitive. Also soya tends to give an undesirable taste. The above process gives a stable emulsion with a comparatively small amount of protein and with no undesirable flavour.
