Method for the preparation of fermented dry or semi-dried meat products, with partial substitution of the animal fat and direct incorporation of olive oil
View Patent ↗Method for the preparation of fermented dry or semi-dried meat products, with partial substitution of the animal fat and direct incorporation of olive oil Method for the preparation fermented dry or semi-dried meat products, with direct incorporation of olive oil. The said method includes the following phases: (a) mixing of the meat with cultures, sugars, preservatives and auxiliary salts, (b) admixture of olive oil and fat, (c) mixing until the desirable meat-fat grain is achieved, (d) stuffing of the meat paste in casings, (e) fermenting of the product in a chamber with relative humidity 95-80% and temperature of 25-20° C., (f) dehydration in a chamber 10 with relative humidity 80-75% and temperature 12-17° C. For the partial fermenting process products, the stages (e) and (f) are modified as follows: (e′) fermenting of the product in a chamber with relative humidity 75-60% and temperature of 25-30° C. for 24-30 hours, (f′) heating of the product up to core temperature of 55° C. and dehydration with relative humidity 75-80 % and temperature of 12-17° C. The fermented dry and semi-dried meat products with direct incorporation of olive oil, which are produced according to this method, have excellent stability from a structure point of view (consistency) and keep the physical and chemical characteristics of the olive oil.
1. Method for the preparation of fermented meat products in which liquid olive oil is stably incorporated to replace part of added animal fat, comprising the following steps:
(a) Meat at −4° C. is first mixed with salt, sugars, preservative, auxiliary salts and cultures;
(b ) Then, liquid olive oil and animal fat are added in the resulting mixture at −2° C., wherein the liquid olive oil replaces part of the animal fat to be added;
(c) Mixing continues until the desirable meat and fat grain is achieved;
(d) Subsequently, the resulting mixture is led to stuffing machines, where it is stuffed in casings under vacuum conditions of about 1000 mbar;
(e) The resulting meat products are then led to maturation chambers with an adjustable relative humidity of 95-80%, a temperature of 25-20° C., and an air velocity of 0.5-0.8 m/sec; with the time of stay in the maturation chamber depending upon on the size of the resulting meat products; and
(f) The resulting meat products are led to a dehydration chamber with an adjustable relative humidity of 80-75%, a temperature of 12-17° C., and an air velocity 0.5-0.1 m/sec.
2. Fermented meat products with incorporated liquid olive oil produced according to the method of claim 1 .
3. Method for the preparation of partially fermented meat products in which liquid olive oil is stably incorporated to replace part of added animal fat, comprising the following steps:
(a) Meat at −4° C. is first mixed with salt, sugars, preservative, auxiliary salts and cultures;
(b) Then, liquid olive oil and animal fat are added in the resulting mixture at −2° C., wherein the liquid olive oil replaces part of the animal fat to be added;
(c) Mixing continues until the desirable meat and fat grain is achieved;
(d) Subsequently, the resulting mixture is led to stuffing machines, where it is stuffed in casings under vacuum conditions of about 1000 mbar;
(e) The resulting meat products are then led to a maturation chamber with adjustable relative humidity of 60-75%, a temperature of 25-30° C., and an air velocity 0.5-0.8 m/sec, wherein the fermentation lasts 24 hours; and
(f) The resulting meat products are then heated to a core temperatures of 55° C. and are led to a dehydration chamber with an adjustable relative humidity of 80-75%, a temperature of 12-17° C., and an air velocity 0.5-0.1 m/sec.
4. Partially fermented meat products with incorporated liquid olive oil produced according to the method of claim 3 .
