Product Description
Fresh fruits and vegetables primary task is maintaining perishable fruit appearance, hardness, texture, flavor, appearance. Most of the fresh fruits and vegetables, the loss of appearance will cause lose value.
Postharvest fresh fruits and vegetables is still living, continue to conduct a series of physiological changes, makes its unique flavor, taste more fully revealed in color, flavor and nutrients more suitable for the needs of the people, this process is called ripening stage, then gradually lost, and the original color fragrance and the nutrition component and softening, disintegration, trying to delay the senescence phase; fresh fruits and vegetables ripening and senescence process to maintain the original quality process, this time means the preservation period.
Fresh fruits and vegetables postharvest physiological changes of the main factors are temperature, humidity, air, packaging, mechanical damage,which may cause weight loss, loss of fresh, atrophy, color and luster descends, fruit with aging and death. Ethylene can induce climacteric respiration peak early arrival,prompting early maturation, senescence.
Temperature, postharvest fresh fruits and vegetables with a large number of field heat, have strong respiration heat. In general, in a certain temperature range, every increase of 10° C respiratory intensity is increased by 1-1.5 times or more. The respiration rate increased, the material consumption is bigger, the storage life is shortened. In 30 ° -60°, fungi, bacteria and microorganism activity and multiply the most exuberant, low temperature can make the fresh fruits and vegetables victory activity slows down, inhibiting fungi and other microorganisms breeding.
Humidity, slightly dry or humid can inhibit respiration, low humidity, dry, will increase transpiration.
Modified atmosphere packaging, the atmosphere, and containing 20.9% 278% N 0.03% CO2, and other trace gases. To reduce storage environment in 2 concentrations, can inhibit the respiration of fruits and vegetables and the dormant part, also can kill microorganisms or inhibition of its activity. Appropriately increasing the concentration of CO2, can inhibit the respiration of fruits and vegetables, also in inhibiting ethylene synthesis, and inhibition of ethylene on fruits and vegetables have effect. Fresh fruits and vegetables with precocious puberty and aging caused mainly by ethylene.
Mechanical damage, with mechanical damage of fruits and vegetables, respiratory intensity will increase dramatically, called wound respiration. In addition, mechanical damage to the wound will increase transpiration, especially very susceptible to microbial function and cause deterioration of decay.
You can see by, fresh fruits and vegetables postharvest, should have as long preservation period, must as soon as possible rapid removal of field heat, inhibit respiratory heat, stored in suitable temperature, humidity, gas environment, decrease respiration and transpiration, inhibit or kill microorganisms, removal of ethylene, ethanol, acetaldehyde ( leading to ferment corruption ) ( cause aging fermentation ) and other harmful gases.
