    • PROBLEM TO BE SOLVED: To obtain a soybean protein useful for producing processed meat products with good palate feeling and physical properties and also reduced in jellied meat development by proteolysis so as to keep the soluble nitrogen index of the final protein in a specific aqueous common salt solution within a specified range. SOLUTION: This soybean protein for pickling use with high solubility to salt, having 40-60% soluble nitrogen index in a 10% aqueous common salt solution at 5 deg.C is obtained by the following procedure: defatted soybeans as feedstock are dissolved in 9 wt. times of water, the resulting bean-curd refuse is removed by centrifugal separation to obtain soybean milk; the soybean milk thus obtained is adjusted to pH 4.5 to effect isoelectric point precipitation of soybean protein, which is then collected by centrifugal separation; the soybean protein thus collected is neutralized with caustic soda into a 4-12 wt.% soybean protein solution; a protease at 0.08-0.2 wt.% in the content on a dry basis is then reacted for 10-30 min to the above soybean protein solution; the resultant reaction liquid is then evaporated to dryness.

    • PURPOSE:To obtain the subject protein not foaming during its production processes, reduced in the foaming also when processed, and good in processing workability, by adding an O/W type emulsion comprising a specific component at a specific stage in the process for producing the separated soybean protein. CONSTITUTION:The separated soybean protein is produced by extracting a soybean raw material with water, precipitating the extract under an acidic condition, preferably at a pH of 4.4, neutralizing the obtained protein fraction, heating the neutralized product, and subsequently drying the product. In the method for producing the separated soybean protein, an O/W type emulsion comprising (A) two kinds of emulsifiers (preferably the combination of an emulsifier comprising a sucrose oleate ester having a HLB of 1-3 with an emulsifier comprising a sucrose fatty acid ester having a HLB of >=5) and (B) a medium chain triglyceride (e.g. the triglyceride of a 6-14C saturated fatty acid such as caprylfc acid) is added in an amount of 10-40% based on the weight of protein in the soybean raw material at an arbitrary stage after the process for obtaining the protein fraction and before the process for drying the product.
