Cleaning, Disinfection, and Retain Freshness of Fruits and Vegetables

JHY empowers the Cold-Chain Storage and Transportation of Fresh Agricultural Products

China is one of the most populous countries in the world. We are not only a major fresh agriculture producer but also a major consumers. Every year we have plenty of fresh fruit and vegetables transported from south to north, from west to east. However, Food waste or loss is numerous and occurs throughout the food system due to conditions such as insufficient skills, natural calamities, lack of proper infrastructure, and poor practices. For instance, around 0~ 30% of losses of fresh fruits and vegetables are due to product loss and deterioration during the production and sales process, which caused a direct annual economic loss of hundreds of billion yuan. It is a huge waste of social resources.

Most fruits, vegetables, and cereals produce gaseous ethylene and carbon dioxide during storage. It is said that such gaseous ethylene and carbon dioxide promote the ripening of the above foods and, thus, hasten the deterioration or perishing thereof. It is presumed that calcium peroxide removes ethylene and carbon dioxide, which are produced from the food. That is, calcium peroxide produces oxygen and is converted into slacked lines due to moisture present, and the oxygen reacts with ethylene, and the calcium hydroxide catches carbon dioxide.

 

Calcium Peroxide performs the Following Functions:

1. Retaining the Freshness of the Foods

 

2. Deodorizing the Foods

 

3. Conventional germicides and/or insecticides may be used together therewith, if needed.

       Keep Fruits and Vegetables Stay Fresh:

  • Data shows that the amount of oxygen is such that the amount of oxygen produced from 1g of calcium peroxide is capable of reacting with 2.5 ml of gaseous ethylene having a pressure of 0.1 atm.
  • The afore-said foods produce ethylene and carbon dioxide at very low rates, e.g. it is said that 1kg of banana produces approximately 1 mg of ethylene and approximately 1.7 mg of carbon dioxide.
  • Therefore, the freshness of the afore-said foods can be retained for a long period of time, usually for approximately two months or more.

 

       Reference dosage of Calcium Peroxide:

  • The amount of calcium peroxide used varies depending upon the particular food and the period for which the food is stored or transported. In general its amount may be within the range from 1 to 50 g, preferably 10 to 30 g, per kg of the food.

Calcium Peroxide Handling and Storage:

  • Be placed in storehouses and ship holds in powders or granules forms used for storage or transportation of the foods.
  • Be placed in bags and other types of containers used for storage or transportation of the foods.
  • Be placed in a refrigerator.

 

 

Notices:

  • It is preferable that these powders or granules are not in contact with the food, although calcium peroxide does not exert a special, undesirable influence on the food. 
  • Usually, these powders or granules are placed in a small bag or other vessel prior to use. 
  • Calcium peroxide may also be used in the form of a thin layer, which is placed inside a small bag or which is sandwiched between two pieces of paper.

 

 

Other Products：

Sodium percarbonate can be used for food preservation and disinfection, 1% sodium percarbonate aqueous solution can keep fruits and vegetables in storage for 4-5 months without deterioration.
