Abstract
The present invention discloses a nano liposome used for preservation of dry-salted hams and a preparation method of the nano liposome. The technical scheme is characterized in that raw materials andthe preparation method are as follows: 10-15 mg of black pepper essential oil, 22.5 mg of soybean lecithin, 12 mg of lard, 5 mg of camphor and 5 mg of menthol are taken; the taken materials are heatedto 35 DEG C; the heated materials are dissolved in 9 ml of olive oil to be vibrated and shaken evenly; rotary evaporation is conducted at 35 DEG C; 9 ml of ether is added for dissolving and further for obtaining an oil-phase ether solution; 5-10 mg of a wall-broken pollen extract, 5-10 mg of sodium citrate, 5-10 mg of potassium lactate, 5-10 mg of sodium polyphosphate, 1 mg of alpha-olefin sulfonate, 1 mg of Tween and 0.2 mg of sodium cholate are taken to be dissolved in 3 ml of a PBS buffer solution; the dissolved materials are poured into the oil-phase ether solution; and vacuum homogenizing, ultrasound treating and centrifuging are successively conducted; an intermediate aqueous-phase part is taken to be subjected to rotary evaporation; and filtering by a microporous filter membrane filter is conducted to obtain a filtrate. Advantages are as follows: the nano liposome is good in dispersibility, high in stability and good in anti-oxidation effects after being applied on the surfacesof the hams.
Description
technical field [0001] The invention belongs to the technical field of meat preservation, and in particular relates to a nano-liposome for ham preservation and a preparation method thereof. Background technique [0002] Dry-cured ham is the most unique traditional livestock food in the Mediterranean region, such as Spanish Serrano and Iberian, Italian Parma and French Bayonne ham. Jinhua ham and Xuanwei ham, as the most traditional livestock products of the Chinese nation, are also well-known at home and abroad. For a long time, the corruption of dry-cured ham has caused great economic losses to the ham industry, so it has been highly valued by people in the industry at home and abroad. During the production process of dry-cured ham, myoglobin is easy to oxidize, which makes the product fade and the fat and protein are over-oxidized, resulting in the deterioration of flavor; at the same time, the serious loss of surface water in the production process leads to high salt cont...
