Description

Iris sepia muscle modification method
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a iris cuttlefish muscle modification method.
Background
In recent years, iris tectorum, also called red squid or south squid, becomes one of main fishing objects of a fish boat with a light cover net in the south sea. The problems of high acidity, hard taste and the like of the fleshy quality of the iris cuttlefish are solved, the fresh selling price is low, the enthusiasm of fishermen in fishing is low, usually, after the low-value fishery objects such as the iris cuttlefish are captured by a fishing boat, the iris cuttlefish is thrown back into the sea again, and the resources cannot be well developed and utilized. The processed iris squid product is in a substantially blank state, and the unsuitable muscle property processing is one of the obstacles preventing the deep processing. Therefore, improving the meat quality of iris cuttlefish has an important role in improving the commodity value of iris cuttlefish, and how to change the muscle properties of iris cuttlefish becomes a key problem to be solved.
Most aquatic products are tender in muscle, the northleonurus squid, the peru squid and the like of cephalopods are high in meat elasticity and good in taste, muscle modification is not needed generally, and more studies are conducted on the improvement of the water retention capacity of the muscle by adopting a water retention agent such as composite phosphate and the like so as to keep the palatability of the muscle in the processing process. Phosphate has a muscle softening effect, but when added at a high concentration, metal astringency is generated, and excessive intake of phosphate causes a certain harm to the human body. Therefore, there is a need to find more suitable methods to improve the muscle properties of iris and adjust the pH of the muscle.
Disclosure of Invention
Aiming at the defects of the prior art, the invention aims to provide a iris cuttlefish muscle modification method which can effectively improve the muscle texture characteristics, improve the crosslinking property and elasticity of muscle protein and reduce the hardness.
The aim of the invention is achieved by the following technical scheme:
a method for modifying iris cuttlefish muscle, comprising the following steps:
(1) Performing ultrasonic water bath treatment on iris cuttlefish;
(2) Soaking iris cuttlefish treated in the step (1) in sodium chloride, calcium chloride, propylene glycol and trypsin solution;
(3) And (3) taking the iris cuttlefish treated in the step (2), and carrying out deacidification treatment by adopting sodium bicarbonate solution to realize the modification of the iris cuttlefish muscle.
The power of the ultrasonic water bath in the step (1) is 200-400 w, and the time of the water bath is 5-10 min.
Preferably, the power of the ultrasonic water bath is 300w and the time of the water bath is 7min.
In the step (2), the mass fraction of sodium chloride is 2% -4%, the mass fraction of calcium chloride is 0.5% -1.0%, the mass fraction of propylene glycol is 2% -5%, and the mass fraction of trypsin is 0.01% -0.03%. The temperature of the iris cuttlefish soaked in the solution of sodium chloride, calcium chloride, propylene glycol and collagenase is 20-30 ℃ and the soaking time is 2-4 h.
Preferably, the mass fraction of sodium chloride is 3%, the mass fraction of calcium chloride is 0.8%, the mass fraction of propylene glycol is 3%, and the mass fraction of trypsin is 0.02%. The soaking temperature of Iris sepia in sodium chloride, calcium chloride, propylene glycol and collagenase solution is 25deg.C, and the soaking time is 3h.
The mass fraction of sodium bicarbonate in the step (3) is 0.1-1.0%, and the deacidification time is 20-30 min.
Preferably, the mass fraction of sodium bicarbonate is 0.5%, and the deacidification time is 25min.
The invention uses ultrasonic wave to treat meat, which can destroy the integrity of muscle cells and promote the action of enzymes in muscle. The content of myofibrillar protein and collagen in the muscle is an important factor influencing the taste of the muscle, and researches show that the content of collagen in the iris cuttlefish is higher than that of a common aquatic product, so that the ultrasonic treatment of the iris cuttlefish muscle can promote the rupture of the myofibrillar protein and weaken the collagen, thereby reducing the shearing force of the muscle and achieving the effect of modifying the meat quality. Meanwhile, through the hydrolysis of trypsin on collagen, the combination treatment of enzyme and ultrasound can better improve the meat quality. In addition, mineral ions and alcohols can promote endogenous enzymes to change muscle structures, improve muscle texture characteristics, improve the crosslinking property and elasticity of muscle proteins, and reduce hardness. Sodium bicarbonate solution is slightly alkaline, so that the acidity of muscles can be improved, and the structure of the muscles can be promoted to be changed. Through the compound synergistic treatment, the muscle property of the iris cuttlefish can be obviously improved.
Compared with the prior art, the invention has the following effects:
(1) The additive used in the invention has the characteristics of low cost and safety;
(2) The method can improve the texture characteristics of the muscles and the acidity of the muscles, and better improves the processing adaptability of the muscles;
(3) The method has great significance and value for promoting rehydration and reducing water activity of the subsequent dried processed products.
(4) The method has the advantages of simple operation process, feasible technical conditions and lower cost, and is suitable for market and industrial popularization.
