Problems solved by technology

[0002] At present, the raw materials for shark fin processing often only use the cartilage in the dorsal and pectoral fins of sharks, and because the amount of cartilage in the dorsal and pectoral fins of sharks is small, the price of shark fin products remains high, and excessive hunting leads to the endangerment of shark species
[0003] In order to effectively solve the above problems, a lot of research has been done in the industry. Now, artificial shark fins have begun to appear, which use pectin, gelatin, and sodium alginate as raw materials, and are made after compounding and curing. Although the price is low, the source of raw materials is wide. But it does not have the taste of natural shark's fin, and its nutritional value is also low; and in order to achieve the appearance and color of natural shark's fin, it also adds pigments such as Sunfast Yellow-No.3, which is not conducive to human health

Embodiment 1

[0029] A processing technology for replacing shark fin products, comprising the following processing steps:

[0030] Select 100 g of shark tooth bone, wash the surface impurities with pure water, put it into a freezer pulverizer, fill it with liquid nitrogen to quickly drop the temperature to -50 ° C, and crush the shark cartilage into 200-400 mesh powder after embrittlement, add 3000g of purified water was heated to 120°C for gelatinization for 2 hours to obtain a gelatinized feed liquid; the gelatinized feed liquid was put into a centrifuge and centrifuged at 2000r / min for 20min, after removing the slag, add 12g of sodium alginate to the upper layer of feed liquid and stir Uniform, to get semi-finished products; the material liquid added with thickener is mechanically extruded into fins similar to shark fins; the fins are placed in 20% calcium chloride, 1% magnesium chloride and 79% purified water Cured in the solidification liquid for 20min. After rinsing, freeze-drying at...

Embodiment 2

[0032] A processing technology for replacing shark fin products, comprising the following processing steps:

[0033] Select 200g of shark water keel, wash the surface impurities with pure water, put it into a freezer grinder, fill it with liquid nitrogen to quickly drop the temperature to -20°C, and crush the shark cartilage into 200~400 mesh powder after embrittlement, add 1000g Purified water was heated up to 80°C and gelatinized for 8 hours to obtain a gelatinized feed liquid; the gelatinized feed liquid was put into a centrifuge, centrifuged at 1000r / min for 30min, and after removing slag, 2g of fish float glue was added to the upper layer of feed liquid, and stirred evenly. Obtain a semi-finished product; the feed liquid added with a thickener is mechanically extruded into a fin-like thing similar to a shark's fin; Curing in liquid for 20min. After rinsing, freeze-drying at a temperature of -35°C, after selection and packaging, the finished product is obtained.

Embodiment 3

[0035] A processing technology for replacing shark fin products, comprising the following processing steps:

[0036] Select 300g of shark keel, wash the surface impurities with pure water, put it into a freezer pulverizer, fill it with liquid nitrogen to quickly drop the temperature to -30°C, embrittle the shark cartilage and crush it into 200~400 mesh powder, add 3000g of purified Water, heated up to 100°C for gelatinization for 4 hours to obtain gelatinized feed liquid; put the gelatinized feed liquid into a centrifuge, centrifuge at 2000r / min for 10 min, add 20g of gelatin to the upper layer of feed liquid after removing slag, and stir evenly to obtain a semi-finished product ; The feed liquid added with a thickener is mechanically extruded into fins similar to shark fins; the fins are placed in a solidified liquid composed of 10% calcium chloride, 10% magnesium chloride and 80% purified water Cured for 20min. After rinsing, freeze-drying at a temperature of -40°C, after s...

Abstract

The invention relates to the technical field of imitated shark fin processing, and particularly relates to a processing technology of an imitated shark fin product. The processing technology comprises the following steps of: 1, picking and washing shark cartilage as a raw material; 2, placing the shark cartilage in the step 1 in a freezing crushing machine for crushing the shark cartilage; 3, adding water in the frozen and crushed shark cartilage for being warmed and pasted to obtain a pasted feed liquid; 4, centrifuging the pasted feed liquid in a centrifugal machine to remove bone slag; 5, adding a thickening agent in the pasted feed liquid to obtain a semi-finished product; 6, mechanically extruding the semi-finished product to a fin-shaped object similar to the shark fin; 7, curing the formed fin-shaped object in a curing liquid; and 8, washing, freezing and drying, selecting and packaging to obtain a finished product. According to the processing technology, the shark cartilage is used as an imitated raw material for processing and producing the shark fin, thus original nutritive value and taste are enabled to be unchangeable, and resources of the whole shark can be fully utilized, waste is changed into valuable, the amount of killing the shark in the world is reduced, and the price of the edible shark fin is lowered.
