Embodiment 1

[0028] S1. Selection of raw materials: select 25.0-33.5g of fresh sea cucumbers, plump, thick meat, fresh and pollution-free live sea cucumbers;

[0029] S2. Remove intestines and viscera: cut fresh sea cucumber from the ventral surface forward from the anus to 1 / 4 of the body length, quickly remove the intestines and viscera, wash with water, and drain;

[0030] S3. Boiling: put the sea cucumber in deionized water at 100°C and boil for 30 minutes to fix the shape of the sea cucumber;

[0031] S4. Hot air drying: The hot air drying is carried out in the electric blast drying oven in the laboratory, the set temperature is 30°C, and the drained sea cucumbers are evenly placed on the tray of the drying oven. The specific drying method After drying for 1 hour, slow recovery for 1 hour, and repeat twice in total; measure the water content of sea cucumbers during slow recovery;

[0032] S5. Perform microwave vacuum drying on the sea cucumbers. Every 10 minutes of drying, slow dryin...

Abstract

The invention discloses a method for preparing dried sea cucumbers through combined drying, and relates to the technical field of marine product drying processing. The method specifically comprises the steps of viscera removal and boiling of sea cucumbers, hot air drying treatment and microwave vacuum drying treatment. Two drying modes of hot air drying and microwave vacuum drying are combined; and by utilizing segmented drying, the advantages of the two drying modes are fully played, and the method has important significance in improving the sea cucumber drying efficiency and quality and reducing the treatment cost. The process is simple, energy-saving and environment-friendly, the drying efficiency can be obviously improved, the technology is easy to control in real time, and continuous and automatic clean production can be realized; the sea cucumbers prepared by the method disclosed by the invention are good in appearance, quick in rehydration, sanitary and safe, and the original nutritional ingredients of the sea cucumbers can be effectively reserved.

Description

technical field [0001] The invention relates to a method for drying sea cucumbers, belonging to the technical field of food processing. Background technique [0002] As one of the important marine invertebrates, sea cucumber is high in protein, rich in nutrition, and can also be used for medicine. It is the main species of aquaculture in my country. However, it is easily autolyzed after extraction from seawater, due to the action of its own enzymes, which is often referred to as cellular self-digestion. Therefore, sea cucumbers must be processed immediately after harvesting. Today, more than 80% of fresh sea cucumbers from all over the world are processed into dehydrated products to extend the shelf life for long-term preservation. [0003] Existing drying methods include hot air drying (HD), natural drying, freeze drying and microwave vacuum drying (MVD). Hot air drying is to circulate the heated hot air. When it flows through the surface of the raw material, it accelera...
