CN103385282A - Nano preservation method for chilled fresh meat - Google Patents

Abstract

The invention relates to the technical field of chilled fresh meat preservation, and particularly relates to a nano preservation method for the chilled fresh meat. A process flow comprise the steps of (1) killing a livestock after knocking out the livestock by using three-point low voltage hemp electricity ; (2) recycling blood by adopting vacuum bleeding; (3) peeling of skin after scalding with steam; (4) excising lymph after enucleating cavity, checking weight after finishing; (5) washing with ultrasonic waves, cutting into fresh meat after separating the meat from bones; (6) cooling to remove acid; (7) checking the quality of the fresh meat synchronously; (8) vacuum packaging; (9) putting one nano bioactive detoxification antistaling agent in every five packaged fresh meat; and (10) loading the packaged fresh meat on a shelf for refrigeration, and selling the refrigerated meat. By adopting the method to preserve the fresh meat, a preservation period is prolonged; the quality of the chilled fresh meat is improved; taste of the chilled fresh meat is improved; nutrients of the chilled fresh meat is enhanced; operations is simple; and effect is obvious.

Description

Cold fresh meat nanometer preservation method

Technical field

The present invention relates to the fresh-keeping technical field of cold fresh meat, especially a kind of cold fresh meat nanometer preservation method.

Background technology

Along with the requirement of people's quality of life is more and more higher, in the middle of life, requisite food pork also rises to healthy and safe and the higher cold fresh pork of nutritive value from general fresh pork, but present cold fresh meat cold storing and fresh-keeping technology storage life is short, and fresh-keeping quality is not obvious and equipment investment is large.

Summary of the invention

Short in order to overcome existing cold fresh meat cold storing and fresh-keeping technology storage life, the deficiency that fresh-keeping quality is not obvious and equipment investment is large, the invention provides a kind of cold fresh meat nanometer preservation method.

The technical solution adopted for the present invention to solve the technical problems is: a kind of cold fresh meat nanometer preservation method, and the technological process of the method comprises:

(1), livestock is adopted rear assassination of bikini low pressure fiber crops electricity;

(2), the vacuum bloodletting is reclaimed;

(3), steam scalds the rear peeling of hair;

(4), go out chamber, check the weight after extracing lymph and doing dressing of carcass;

(5), Ultrasonic Cleaning, cut apart, pick a bone, mowing goes out fresh meat;

(6), cooling acid discharge, before acid discharge with the lactic acid solution spray of the 3-5% surface at meat;

(7), verification of synchronization fresh meat quality;

(8), pack packing employing vacuum packaging;

(9), adopt nanometer fresh-keeping, nano-bioactive detoxification antistaling agent is folded up one in every 5 packaged fresh meats;

(10), upper commodity price refrigeration is sold.

The invention has the beneficial effects as follows:

(1), with low cost;

(2), effect is unique: can improve product quality, be natural modifying agent and the detoxifying agent of food;

(3), freshness date limit for length: the cold fresh meat shelf-life can reach more than 6 months.

(4), easy to use.

The specific embodiment

Embodiment:

A kind of cold fresh meat nanometer preservation method, the technological process of the method comprises:

(1), livestock is adopted rear assassination of bikini low pressure fiber crops electricity;

(2), the vacuum bloodletting is reclaimed: utilize sebific duct that vavuum pump and vacuum fleam are communicated with vacuum tank respectively, adopt the principle of vacuum absorption to extract out the blood in the pig body external;

(3), adopt steam to scald the rear peeling of hair;

(4), go out chamber, check the weight after extracing lymph and doing dressing of carcass;

(5), Ultrasonic Cleaning, cut apart, pick a bone, mowing goes out fresh meat;

(6), cooling acid discharge, before acid discharge with the lactic acid solution spray of the 3-5% surface at meat;

(7), by professional's verification of synchronization fresh meat quality;

(8), packing adopts vacuum packaging;

(9), adopt nanometer fresh-keeping, nano-bioactive detoxification antistaling agent is folded up one in every 5 packaged fresh meats;

(10), upper commodity price refrigeration is sold.
