The invention discloses a making method of fermented chilli sauce. The preparation method includes the following steps that firstly, fruit paste is prepared; secondly, the fruit paste is subjected to enzymolysis so that an
enzymatic hydrolysis solution can be prepared; thirdly,
cane sugar is added into the
enzymatic hydrolysis solution, the concentration of cage
sugar is made to be 0.5-0.7 g / mL, by weight, 20-30 parts of water is immediately added after placement lasts for 15-25 min, uniform stirring is performed, filtering is performed, and filter liquor is prepared; fourthly, by weight, 3-5 parts of
agar is added into the filter liquor, heating and boiling are performed for 5-10 min after the mixture is placed for 2-3 h at
room temperature, then temperature is lowered to 42-45 DEG C, then by weight, 5-10 parts of salt is added and is uniformly stirred, and an
agar solution is prepared; fifthly, by weight, 60-80 parts of fresh chillies are smashed, temperature is raised to 42-45 DEG C, then the ager solution is added and uniformly stirred, and a mixture is obtained; sixthly, at
room temperature, after the mixture is solidified, the mixed is placed in a
fermentation tank and naturally fermented for 10-15 days at 25-30 DEG C. The chilli sauce made through the method is uniform in taste, low in content of
nitrite and fresh in taste.
