The invention relates to low-
protein starch paste easy in
brewing. The low-
protein starch paste is mixed and prepared from, by weight percentage, 35-50% of rice
starch, 30-45% of
corn starch, 8-13% of soybean
fiber powder and 4-7% of
xylitol, wherein the rice starch and
corn starch are the main raw materials, the soybean
fiber powder, the
xylitol and the like are auxiliary materials, and the auxiliary materials are added after the main raw materials are processed. A preparation method of the low-
protein starch paste includes the steps of mixing and regulating, extruding,
drying,
superfine grinding, mixing and blending, and the like. The low-protein
starch paste has the advantages that an extruding generator in multi-gradient physical-field generators is fully utilized and combined with the
superfine grinding technology, the prepared low-protein
starch paste can satisfy the
protein intake requirement of a patient with
kidney disease, and the low-protein starch paste is good in taste and edibility, high in
digestion rate and
utilization rate, and the like as compared with other low-
protein food. In addition, compared with paste products with
normal protein contents, the low-protein starch paste has the advantages that after the patient with the
kidney disease eats the low-protein starch paste for a certain period of time, the
urinary protein, serum
creatinine and
urea nitrogen contents of the patient are in a decreasing trend, the total
serum protein and
serum albumin contents of the patient are in an increasing trend, and the state of the
kidney disease can be relieved.
