Preparation method of low-salt bone-removed instant ham using Landrace pig leg as raw material

Abstract

The present invention discloses a preparation method of a low-salt bone-removed instant ham using a Landrace pig leg as a raw material. The preparation method is characterized by comprising the following steps: bone-removed shaped raw material meat and a pickling agent are put into a rolling and rubbing machine for conducting vacuum rolling, rubbing and pickling; the raw material meat is taken outfrom polyethylene bags, transglutaminase and collagenase are added, and vacuum rolling, rubbing and tenderizing are conducted; the rolled and rubbed raw material meat is subjected to vacuum packagingby using polysulfone film bags for film sleeving pickling and dehydrating; the raw material meat is taken out from the polysulfone film bags, then the raw material meat is packaged under vacuum by using polyethylene bags for still sealed re-softening and enzymatic hydrolysis promoting; the raw material meat is taken out, then the raw material meat is packaged under vacuum by using polysulfone film bags for film-sleeving air-drying and dehydrating; and finally, aging is conducted until the weight loss of the raw material meat reaches 40%, so that a finished product is obtained. Advantages areas follows: the low-salt bone-removed instant ham is short in production cycle, low in salt, high in moisture content, excellent in mouthfeel and taste and high in safety.

Description

technical field [0001] The invention relates to a preparation method of instant ham, in particular to a preparation method of low-salt deboned instant ham with Landrace pork leg as raw material. Background technique [0002] As a traditional fermented meat product in my country, ham has a long history and is deeply favored by people for its unique flavor and taste. Traditional ham curing generally goes through steps such as curing, leg washing, shaping, air-drying and fermentation. However, there are many problems in the production process, which restrict the expansion of the sales market and the quality of ham. The main problem is the long cycle. For example, Jinhua ham generally takes 10 to 12 months, while Spanish Iberian ham and Italian Parma ham need to mature for 2 to 3 years. The dehydration of traditional dry-cured ham in the later stage is due to the surface crusting phenomenon, which makes the dehydration speed slow down. To meet the water content requirements of ...

Problems solved by technology

Traditional ham curing generally goes through the steps of curing, leg washing, shaping, air-drying and fermentation. However, there are many problems in the production process, which restrict the expansion of the sales market and the quality of ham.

The main problem is the long cycle. For example, Jinhua ham generally takes 10 to 12 months, while Spanish Iberian ham and Italian Parma ham need to mature for 2 to 3 years.

The air-dried dehydration of traditional dry-cured ham in the later stage is due to the phenomenon of surface crusting, which makes the dehydration speed slower. To meet the water content requirements of the final product, ham production must go through long-term water migration and volatilization, and the cycle is longer

Second, the final product has high salt content and low water content, so it is not suitable for instant consumption

The high salt content also determines that its eating method can only be based on soup seasoning. It is not suitable for direct sliced ​​food, and it is easy to cause cardiovascular diseases such as high blood pressure. The direct manifestation of low water content is that the ham is dry and hard, which affects the quality of the ham. taste and texture

The third is that marinating with bones is easy to be corrupted

However, Landrace pork leg meat has low intermuscular fat content, high tendon and fascia content, high hardness, poor texture and rough taste
