Problems solved by technology

However, if a large amount of phosphate is used, it will affect the quality of the product. High concentration of phosphate will cause the product to have a metallic astringent taste, which will cause the product's flavor to deteriorate and the structure to be rough. These are ...

[0029] Trehalose 2%, potassium bicarbonate 0.5%, chitosan 0.5%, the balance is water.

Embodiment 2

[0031] A phosphorus-free water-retaining agent suitable for frozen tilapia fillets, consisting of the following components in mass percentage:

[0032] 8% trehalose, 2.5% potassium bicarbonate, 2.5% chitosan, and the balance is water.

Embodiment 3

[0034] A phosphorus-free water-retaining agent suitable for frozen tilapia fillets, consisting of the following components in mass percentage:

[0035] 4% trehalose, 1.2% potassium bicarbonate, 0.2% chitosan, and the balance is water.

[0036] An application of a phosphorus-free water-retaining agent suitable for frozen tilapia fillets, the specific application method is:

Abstract

The present invention relates to a non-phosphorus water-retaining agent suitable for freezing storage of tilapia fillets and an application thereof. The provided non-phosphorus water-retaining agent suitable for the freezing storage of the tilapia fillets comprises the following components in percentages by mass: 2%-8% of trehalose, 0.5-2.5% of potassium bicarbonate, 0.5%-2.5% of chitosan, and the balance being water. The non-phosphorus water-retaining agent preferably consists of the following components in percentages by mass: 4% of trehalose, 1.2% of potassium bicarbonate, 0.2% of chitosan and the balance being water. After the application of the non-phosphorus water-retaining agent, the freezing stored tilapia fillets are relatively good in moisture distributions, and the non-phosphorus water-retaining agent effectively avoids moisture loss during freezing storage and enables the comprehensive quality of the freezing stored tilapia fillets to maintain very well. The present invention also discloses the application of the non-phosphorus water-retaining agent suitable for the freezing storage of the tilapia fillets. The concrete application method is simple in steps and high in operability.

Description

technical field [0001] The invention relates to the frozen storage processing technology of tilapia fillets, in particular to a phosphorus-free water-retaining agent suitable for frozen storage of tilapia fillets and an application thereof. Background technique [0002] Freezing is a common original processing method for aquatic products, and it is also an important method for the preservation and transportation of perishable foods for a long time. Freezing can not only keep the color, aroma, taste and shape of aquatic products to a certain extent, but also break through the limitations of time and space. General fish fillets that have not been treated with water-retaining agents will irreversibly become dehydrated due to the water-retaining properties of proteins during freezing and freezing, which will cause protein freezing denaturation, tissue structure damage, and fat oxidation and rancidity will also occur after freezing for a long time After thawing, the water holdin...
