preparation example 1

[0067] A preparation method of orange peel essential oil, comprising the following steps:

[0068] 1. add fresh orange peel powder in the NaCl solution that mass concentration is 1.2%, the solid-liquid ratio of orange peel powder and NaCl solution is 0.1g / mL;

[0069] Ⅱ. The orange peel powder solution obtained was subjected to ultrasonic treatment for 15 minutes, and the ultrasonic power was 180W;

[0070] Ⅲ. Steam distill the orange peel solution after ultrasonication for 20 minutes;

[0071] Ⅳ. Freeze the solution obtained after the distillation fraction is condensed, and collect the essential oil after the water is completely frozen to obtain orange peel essential oil.

Abstract

The invention discloses an aquatic product water retention and fresh keeping agent and a freezing and fresh keeping method, and belongs to the technical field of aquatic product storage. The water retention fresh keeping agent comprises the following raw materials in parts by weight of 4-9 parts of trehalose; 1-5 parts of xanthan gum; 0.6-1.2 parts of a mesona chinensis benth extract; 3-7 parts ofcarboxymethyl chitosan; 1-2 parts of orange peel essential oil; 0.2-0.6 part of carnosol; and 2-3 parts of gamma terpinene. According to the method, the pretreated aquatic products are treated with the water retention and fresh keeping agent and then frozen and stored, the water retention and fresh keeping agent can reduce mechanical damage to muscle tissue in the freezing process and improve thewater-retaining property of the aquatic products, the aquatic products have good sensory evaluation of color, texture, taste and the like, and the freezing and storing time is prolonged; and meanwhile, the water retention and fresh keeping agent disclosed by the invention also has very good antibacterial and antioxidant properties, the decay speed of protein and fatty acid in the aquatic productscan be reduced, and the shelf life of the aquatic products is prolonged.

Description

technical field [0001] The application relates to the technical field of aquatic product storage, in particular to a water-preserving and fresh-keeping agent and a freezing and fresh-keeping method for aquatic products. Background technique [0002] Our country is rich in seafood resources. Every year, fish, shrimp, crab and shellfish have a large output. Aquatic products are rich in nutrition, and the protein content is several to dozens of times that of eggs and milk; Magnesium, phosphorus and other minerals, vitamin A, aminophylline and other ingredients, and its meat is soft and easy to digest. It is an excellent food for people who are weak and need to take care of themselves after illness. However, aquatic products are restricted by various factors such as fishing seasons, geographical conditions, and climate. During storage, transportation, and sales, they are often prone to spoilage due to the proliferation of microorganisms, which will cause changes in the flavor an...
