A kind of method for shaping of thermocoagulation egg products
Technical field
The present invention relates to field of food, specifically a kind of method for shaping of thermocoagulation egg products.
Background technology
The thermocoagulation egg products are take bright egg, salted egg and lime-preserved egg as primary raw material, add or do not add auxiliary material and flavouring, heat the goods that form after canned.Its main technique is the allotment of raw material and auxiliary material, the typing container of cannot not packing into sticking, heat-shaping, dry or moist, halogen boil or not halogen boil, vacuum packaging, sterilization.In type-approval process, because the formation to gel network of the egg protein in albumen protein and ovotransferrins plays a major role, in egg white, protein denaturation is a process slowly, be issued to the required sex change time approximately during 40min in suitable temperature, protein molecule could fully launch, and the gel of formation has larger hardness.Simultaneously, ovalbumin has good foaming characteristic, and in the process of heating, sex change is synchronizeed and carried out with foaming.Due to this white sex change characteristic of birds, beasts and eggs, type-approval process temperature, moisture, time are controlled bad, all can cause the destructurized of thermocoagulation egg products, and there is bubble etc. as not strong in gelation, inside.
Summary of the invention
The objective of the invention is to address the above problem, a kind of method for shaping of thermocoagulation egg products is provided.
The method for shaping of thermocoagulation egg products of the present invention is characterized in that, it comprises following production stage:
(1) raw material is selected: choose birds, beasts and eggs through inspection and quarantine as the raw material egg;
(2) beat eggs: raw material egg white reason is clean, air-dry, remove the surface water mark, get in egg-whisk, mixing speed with 60-80 r/min is beaten, in egg liquid 100 weight portions of beating, add simultaneously salt, 0.1~0.5 weight portion composite phosphate, 0.2~0.4 weight portion of 0.1~1 weight portion to cross konjaku powder, 0.2~0.4 weight portion gellan gum, 0.1~0.5 weight portion monosodium glutamate, 1~2 weight portion chickens' extract and 0.1~0.2 weight portion yeast extract of 250 mesh sieves, stir to egg liquid even, standby after 200 mesh sieves filter;
(3) mixing filling: with the standby egg liquid forming box of packing into, add a cover; Perhaps pour into casing with sausage filler;
(4) pressure shaping: the sample after can is put into pressure cooker, pass into oil-free compressed air, make pressure reach 0.03~0.08Mpa, begin to be warming up to 80~95 ℃, then adjusting pressure is 0.05~0.12Mpa, typing 20~90min;
(5) shaping and spice: egg is done be cut into as required rectangle, the various shapes such as square, circular or heart-shaped, and one or more in cumin powder, pepper powder, chilli powder, monosodium glutamate, soy sauce, essence, bubble green pepper powder are mixed in requirement to taste;
(6) packing: the egg after shaping and spice is vacuumized packing in-0.085~-0.1 Mpa;
(7) sterilization: carry out coolingly after 110~130 ℃ of high temperature sterilizations, make product of the present invention.
Described birds, beasts and eggs are egg, duck's egg or goose egg etc.
The present invention has following characteristics:
(1) the present invention adopts the pressure of air, control the protein denaturation process, and having solved the thermocoagulation egg products increases at the sample moisture that problem and traditional boiling method of type-approval process bubble causes;
(2) by the interpolation of konjaku and gellan gum, make protein in high-temperature denatured process, the gelation of egg products has obtained maintenance, and the products taste that makes is good;
(3) konjaku is rich in food fiber, and several amino acids and trace element have enriched the nutrition of product; And gellan gum can make it have salubrious taste, plays making up the good action that the egg products taste is crossed raw meat.
The specific embodiment
The present invention will be described in detail to reach by the following examples Comparative Examples.
Embodiment:(1) raw material is selected: choose birds, beasts and eggs through inspection and quarantine as the raw material egg;
(2) beat eggs: raw material egg white reason is clean, air-dry, remove the surface water mark, get in egg-whisk, beat with the mixing speed of 70 r/min, in egg liquid 100 weight portions of beating, add simultaneously salt, 0.3 weight portion composite phosphate, 0.3 weight portion of 0.5 weight portion to cross konjaku powder, 0.3 weight portion gellan gum, 0.3 weight portion monosodium glutamate, 1 weight portion chickens' extract and the 0.1 weight portion yeast extract of 250 mesh sieves, stir to egg liquid even, standby after 200 mesh sieves filter;
(3) mixing filling: standby egg liquid is poured into casing with sausage filler;
(4) pressure shaping: the sample after can is put into pressure cooker, pass into oil-free compressed air, make pressure reach 0.05Mpa, begin to be warming up to 90 ℃, then adjusting pressure is 0.1Mpa, typing 70min;
(5) shaping and spice: with the dried rectangle that is cut into of egg, and mix soy sauce;
(6) packing: the egg after shaping and spice is vacuumized packing in-0.09Mpa;
(7) sterilization: carry out coolingly after 120 ℃ of high temperature sterilizations, make the product of embodiment.
The thermocoagulation egg products inside that the present embodiment is made does not have Bubble formation, and mouthfeel is good, and has salubrious taste.
Comparative Examples 1:Different from embodiment is do not adopt the pressure shaping method of step (4), but the typing container that the sample after can cannot not packed into sticking by conventional method to carry out heat-shaping, makes the product of Comparative Examples 1.The product of Comparative Examples 1 produces bubble, and mouthfeel is partially soft.
Comparative Examples 2:Different from embodiment is, does not add konjaku and gellan gum, makes the product of Comparative Examples 2.The product elasticity of Comparative Examples 2 is relatively poor, do not chew sense, and taste is than raw meat.
