Problems solved by technology

[0003] The disadvantages of the above-mentioned technical solutions are: 1) the use of plastic materials may contain toxic substances such as plasticizers. Modern people pay great attention to the natural health of fruits and vegetables. Substances penetrate into fruits and vegetables, causing human health problems; 2) The whole material is hard after being made into plastic granules, which is easy to scratch the plastic surface. In addition, plastic granules are not suitable for fruits and vegetables with uneven surfaces such as cauliflower, and plastic granules are easy to embed 3) The existing technology only considers that negative ions can prolong the fresh-keeping period without considering the problem of bacterial growth in the absence of refrigeration

Embodiment 1

[0046] Weigh 20 parts of tourmaline powder, 30 parts of rare earth, 20 parts of medical stone powder, 10 parts of carbonized rice bran, 10 parts of agar, 2 parts of licorice fiber, 10 parts of eucalyptus oil, and 10 parts of oregano oil.

[0047] Wherein, the preparation method of the tourmaline powder is as follows: grind and sieve the tourmaline to obtain powder, the screen size is 20 mesh or higher than 20 mesh, in principle not more than 50 mesh, because the too fine powder can be easily absorbed by the human body after being inhaled during operation. Deals permanent damage.

[0048] The preparation method of the medical stone powder is as follows: crush the medical stone and sieve to obtain the powder, and the size of the sieve is 10-20 mesh.

[0049] The preparation method of the carbonized rice bran is as follows: first soak the rice bran in water, filter and wash away impurities, then cook, dry and put it into a carbonization furnace for carbonization at a temperature ...

Embodiment 2

[0068] Weigh 30 parts of tourmaline powder, 50 parts of rare earth, 30 parts of medical stone powder, 20 parts of carbonized rice bran, 15 parts of agar, 5 parts of licorice fiber, 15 parts of eucalyptus oil, and 15 parts of oregano oil.

[0069] Wherein, the preparation method of the tourmaline powder is as follows: grind and sieve the tourmaline to obtain powder, the screen size is 20 mesh or higher than 20 mesh, in principle not more than 50 mesh, because the too fine powder can be easily absorbed by the human body after being inhaled during operation. Deals permanent damage.

[0070] The preparation method of the medical stone powder is as follows: crush the medical stone and sieve to obtain the powder, and the size of the sieve is 10-20 mesh.

[0071] The preparation method of the carbonized rice bran is as follows: first soak the rice bran in water, filter and wash away impurities, then cook, dry and put it into a carbonization furnace for carbonization at a temperature ...

Embodiment 3

[0090] Weigh 25 parts of tourmaline powder, 40 parts of rare earth, 25 parts of medical stone powder, 15 parts of carbonized rice bran, 12 parts of agar, 3 parts of licorice fiber, 13 parts of eucalyptus oil, and 13 parts of oregano oil.

[0091] Wherein, the preparation method of the tourmaline powder is as follows: grind and sieve the tourmaline to obtain powder, the screen size is 20 mesh or higher than 20 mesh, in principle not more than 50 mesh, because the too fine powder can be easily absorbed by the human body after being inhaled during operation. Deals permanent damage.

[0092] The preparation method of the medical stone powder is as follows: crush the medical stone and sieve to obtain the powder, and the size of the sieve is 10-20 mesh.

[0093] The preparation method of the carbonized rice bran is as follows: first soak the rice bran in water, filter and wash away impurities, then cook, dry and put it into a carbonization furnace for carbonization at a temperature ...

Abstract

The invention relates to the technical field of fruit and vegetable fresh-keeping, in particular to a special negative ion fresh-keeping agent and fresh-keeping method for fruits and vegetables. The special negative ion fresh-keeping agent is composed of the following components in parts by weight of 20-30 parts of tourmaline powder, 30-50 parts of rare earth, 20-30 parts of medical stone powder, 10-20 parts of carbonized rice bran, 10-15 parts of agar, 2-5 parts of liquorice fiber, 10-15 parts of eucalyptus oil and 10-15 parts of origanum oil. Agar is condensed into soft colloid, and the soft colloid is cut into slices, so that various soft fruits and vegetables such as strawberries, cherries and the like can be placed on the slices, and the effects of buffering and protecting are achieved; negative ions can be generated, so that the effect of prolonging the fresh-keeping period of the fruits and vegetables is achieved; and the special negative ion fresh-keeping agent also has an antibacterial effect and can prevent rapid decay of the fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of fruits and vegetables, in particular to a special negative ion fresh-keeping agent for fruits and vegetables and a fresh-keeping method thereof. Background technique [0002] Refrigeration is usually used to keep fruits and vegetables fresh, but in some areas there may be a lack of power supply and other reasons, and other types of fresh-keeping methods are required. For example, a Chinese patent discloses a masterbatch for fresh-keeping vegetables that can release negative ions, application number 201611113223.4, which records: it specifically relates to a masterbatch for fresh-keeping vegetables that can release negative ions, and the masterbatch for fresh-keeping vegetables that can release negative ions , made of the following raw materials by weight percentage: main body material 65-85%; negative ion generator 4-20%; coupling agent 0.5-2%; dispersant 4-20%; rectified monoglyceride 4-...
