The invention discloses a preparation method of low-salt-content low-fat-content air-dried chickens. The preparation method of the low-salt-content low-fat-content air-dried chickens comprises the following steps: slaughtering live broilers, removing the
feather, carrying out eviscerating, and carrying out
blanching so as to obtain naked chickens; and then, orderly carrying out
pickling, air-
drying,
feather picking, cooking and packing. A step of de-
salting and de-fatting is also included between the step of carrying out air-
drying and the step of carrying out
feather picking; and the de-
salting and de-fatting method comprises the following steps: Step S1, preparing wet mud, namely weighing 35-45 parts of modified food-grade diatomite, 15-25 parts of food-grade
gypsum powder, 6-8 parts of food-grade
silica gel and 3-5 parts of food-grade
alginic acid, parts by weight, carrying out uniform mixing and stirring, adding 90-110 parts of water, and then, carrying out uniform stirring; Step S2, uniformly
coating the wet mud on the surfaces of the air-dried naked chickens, carrying out air-
drying in an air-drying workshop at a temperature of 8-18 DEG C and a
relative humidity of 25-75% until dry mud is formed on the surfaces of the naked chickens, wherein the air-
drying time is 15-25 hours and 400-600 grams of the wet mud is applied on per 1
kilogram of the naked chickens; and Step S3, removing the dry mud on the surfaces of the naked chickens so as to realize de-
salting and de-fatting. The air-dried chickens provided by the invention are obviously reduced in
salt content and
fat content, so that the air-dried chickens are good in taste and healthy.
