The invention relates to a preparation method of composite gel Xinjiang brown cow leather jelly with high gel characteristics, which comprises the following steps: adopting Xinjiang brown cow leather, performing enzymolysis and depilation by using
neutral protease and
xylanase, boiling, filtering,
seasoning, adding low-acyl
gellan gum,
guar gum and
calcium chloride according to a specific proportion, boiling, canning, sterilizing and sealing, thereby obtaining the composite gel Xinjiang brown cow leather jelly. And thus, the composite gel cowhide jelly is obtained. The texture performance of the prepared composite gel cow leather jelly is superior to that of traditional cow leather jelly, the
hardness and
chewiness are remarkably increased by 63.64% and 60.59% respectively, and the storage modulus in
dynamic viscoelasticity is increased; the highest
melting temperature and solidification temperature of the compound
skin jelly are 53.63 DEG C and 36.60 DEG C, and the
melting temperature is increased to 156.06 DEG C; and the freeze-thaw water
loss rate is reduced by 51.31% compared with that of the traditional
skin jelly. The digestibility of the composite gel kraft jelly
protein is delayed, and the predicted
shelf life is 114 days. According to the preparation method disclosed by the invention, the edible hydrophilic
polysaccharide can be added into the traditional cow leather jelly to improve the
gel strength and improve the gel quality.
