Description

Preparation method of barbecue-flavored tilapia skin
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a preparation method of barbecue-flavored tilapia skin.
Background
During the production and processing of fish products, a large amount of leftovers including fish heads, fish skins, fish fins, fish tails, fish bones and residual fish meat are inevitably produced, wherein the fish skins and the fish scales account for about 40-55% of the weight of the raw fish. At present, a small part of the leftovers are used for processing low-cost feed fish meal, and a part of the leftovers are even directly discarded as waste, which causes great waste of fishery resources and pollutes the environment.
The fish skin contains abundant proteins and a plurality of trace elements, the proteins are mainly macromolecular collagen and mucopolysaccharide components, and the fish skin is a good skin-care and beauty-maintaining product for women. The medical research finds that the leucines-leucine in the fish skin has anticancer effect. The fish skin is rich in collagen, and each 100g of dry shark skin contains 67.1g of protein and 0.5g of fat, and the protein is collagen, and has good effects in caring skin and supplementing calcium.
With the continuous improvement of living standard of people, people have higher requirements on diet, and besides enough nutrient components, the food has flavor, appearance and color. To meet the ever-increasing dietary needs of people, many snacks related to fish products appear on the market, and fish skin is one of the snacks. At present, the fish skin products on the market have single mouthfeel and appearance, namely most fish skin products are in irregular and curled shapes under the heated condition, the requirements of people on the color, the fragrance and the taste of food cannot be met, improvement is needed, and the crisp fish skin is tough and difficult to directly eat.
Disclosure of Invention
The invention aims to make up for the defects of the prior art and provides a preparation method of grilled tilapia skin.
In order to achieve the above object, the present invention provides the following technical solutions:
a preparation method of barbecue flavor tilapia skin comprises the following steps:
(1) thawing the stored frozen fish skin, cleaning, cutting into a certain size, and draining for later use;
(2) soaking the fish skin obtained in the step (1) in a degreasing solution which is 3-4 times of the weight of the fish skin, continuously stirring for 30-60 minutes to degrease and remove fishy smell, and rinsing to be neutral after finishing degreasing;
(3) draining the fish skin obtained in the step (2), sending the fish skin into a curing barrel, adding curing seasoning, adding water with the mass of 5-10% of that of the fish skin, uniformly stirring the materials, and sealing and curing for 40-80 minutes;
(4) draining the fish skin pickled in the step (3), then sending the fish skin into a frying pan, frying until the fish skin is puffed, curled and shaped, and then taking out and deoiling for later use;
(5) crushing black rice and brown rice to 20-40 meshes, adding alpha-amylase into the black rice and brown rice according to 750U/g, sending the mixture into a double-screw extruder together for extrusion and expansion to obtain expanded powder, and crushing the expanded powder to pass through a 100-mesh and 140-mesh sieve for later use;
(6) uniformly scattering the puffing powder obtained in the step (5) on the surface of the fried fish skin subjected to deoiling in the step (4), feeding the fish skin into the frying pan again for secondary frying until the fish skin is golden yellow in color and crisp, taking out the fish skin, and centrifugally throwing out the redundant oil on the surface of the fish skin;
(7) and (4) sending the fried fish skin in the step (6) into a hot air tunnel for drying, and then packaging according to the modified atmosphere of the specification to obtain the required barbecue flavor fish skin.
Preferably, the fish skin in the step (1) is tilapia skin.
Further, the degreasing solution in the step (2) is obtained by uniformly mixing 0.1-0.2 wt% of calcium chloride solution, 20-30g/L of acetic acid solution, 0.01-0.03 wt% of mint essence solution and the like.
Further, the pickling seasoning in the step (3) is prepared by mixing refined salt, white granulated sugar, monosodium glutamate, pepper powder, an antioxidant and barbecue seasoning powder according to the mass ratio of (2-3) to (8-10) to (0.5-1.5) to (0.5-0.8) to (0.02-0.05) to (0.8-1.2), wherein the adding amount of the pickling seasoning is 5-10% of the mass of the fish skin before pickling.
Further, the barbecue seasoning powder is prepared by mixing edible glucose, cumin powder, capsanthin, aspartame, disodium ribonucleotide and sodium bicarbonate according to the food standard addition amount.
Further, the temperature of the front, middle and rear sections of the expander is controlled to be 60-80 ℃, 110-.
Further, the hot air tunnel in the step (7) is divided into three sections, wherein the first section is at 190 ℃ for 5 minutes, the second section is at 170 ℃ for 8 minutes, and the third section is at 150 ℃ for 8 minutes.
The invention also provides a barbecue flavor tilapia skin prepared by the preparation method of the barbecue flavor tilapia skin.
The invention has the advantages that:
1. according to the barbecue flavor fish skin, a fish meat processing byproduct tilapia skin is used as a raw material, so that the cost is low, the special taste of the fish skin enriches the types of leisure food in the market, and more choices are provided for consumers.
2. The product takes calcium chloride, acetic acid and mint essence as degreasing and fishy smell removing materials in the preparation process, wherein the acetic acid can not only kill microorganisms, but also partially denature protein, so that the taste of the fish skin is more moderate, and meanwhile, in the vinegar pickling process, volatile basic nitrogen can be leached out, so that the freshness requirement of the fish skin raw material is reduced, and volatile aroma components in the mint essence can cover the fishy smell of the fish skin, so that the taste of the product is optimized.
3. Wrap up for wrapping up in the powder raw materials through black rice brown rice after once frying, wherein black rice brown rice extrudes through twin-screw bulking machine and puffs, in extrusion process, through high temperature, high pressure, the effect of high shear force, make macromolecular substances such as starch, protein, fat, crude fiber cut off into micromolecular substance, improve black rice brown rice's edibility greatly, overcome itself difficult cooking, the palatability is poor, the dispersibility of making and concocting is poor, the drawback that the viscosity is high, it contains active substance such as abundant nutrient composition and polyphenol as brown rice simultaneously, excellent antioxidant capacity has, consequently, can improve the nutritive value of fish skin greatly, be different from conventional refined flour parcel on the market simultaneously, the taste is more unique.
4. In the final drying stage of preparation, the quality and color of the fish skin are directly influenced by the temperature and the time, the phenomenon of burnt skin can occur when the temperature is too high or the time is too long, the finished product is easy to break, the fish skin is easy to generate and the fishy smell is heavy when the temperature is too low or the time is too short, so the best drying effect is achieved by adopting three-stage drying and accurately controlling the temperature and the time.
5. The barbecued fish skin product of the invention furthest reserves the original nutrition and color of the fish skin, has crisp taste and scientific and rigorous preparation method, and is suitable for the application of the fish skin food processing industry.
