Embodiment 1
[0017] 1. Remove impurities from fresh undehydrated red beets, peel them, cut them into pieces, and wash them with ultraviolet disinfection water;
[0018] 2. In a sterile environment, use a food-specific airtight, watertight, and radiation-resistant multi-layer composite film bag for vacuum packaging.
[0019] 3. Put bags of soft-packed canned red beet in a carton for packaging.
[0020] 4. Transport batches of fresh-keeping cans of red beets to the local irradiation center for radiation sterilization. The radiation dose shall be agreed upon by the two parties in advance with the samples to be tested and passed the inspection.
[0021] 5. Inventory and marketing.
Embodiment 2
[0023] 1. Dry the freshly harvested red beets naturally until the dehydration ratio reaches 30% to 60%.
[0024] 2. Remove the impurities from the semi-dehydrated red beets, peel them, cut them into pieces, and wash them with ultraviolet light detoxifying water.
[0025] 3. In a sterile environment, use a food-specific airtight, watertight, radiation-resistant multi-layer composite film bag for vacuum packaging.
[0026] 4. Put the fresh-keeping cans of red beet on the microwave sterilizer of our factory for sterilization. The bactericidal dose is determined according to the conventional dose set by machines of different energies.
[0027] 5. Put the soft-packed canned red beet after microwave sterilization into cartons for packaging, and then stock and market after passing the inspection.
[0028] Effect
[0029] 1. The fresh-keeping soft canned red beets produced by non-high-temperature sterilization technology are not only fresh, crispy and tender, but also can maintain ...

Abstract
The invention relates to a fresh-keeping flex-can of red beets and a preparation method thereof. All the recent canned red beets in the world adopt glass or iron cans, which are produced by high-temperature sterilization technology. The invention aims to solve the problems that the red beets are no longer fresh and become soft. The invention adopts non-high-temperature sterilization technology, such as radiation sterilization method, microwave sterilization method, super-high-pressure sterilization method, intense magnetic field sterilization method, ultrasonic sterilization method, chitosan sterilization method, antibiotic enzyme sterilization method and the like, to produce vacuum flex-cans with complex-film. Fresh flex-canned red beets not only are fresh, spicy, crisp and soft which maintain taste, quality and nutrition of food and overcome the disadvantages of high-temperature sterilization, but also have small sizes and light weight, thus reducing costs of transportation and warehousing and increasing additional values.
Description
technical field [0001] The invention relates to canned food, in particular to a fresh-keeping soft can of red beets, belonging to the technical field of food preservation. Background technique [0002] Red beet is a very popular high-end dish in European and American countries and my country's western food industry. The red cabbage soup cooked with it is the state banquet dish for the Kremlin to entertain the heads of state. Because it is harvested once a year and has a very short edible period, Western countries invented canned red beets that can be sterilized and sterilized to ensure a year-round supply. However, the current best-selling food in the world is made of glass or iron cans. The fly in the ointment is that after high-temperature sterilization, the dishes become soft and rotten, and there is also the smell of iron cans. Contents of the invention [0003] The purpose of the present invention is to aim at the disadvantages of the current high-temperature proces...
