Vacuum freeze-drying technology and its application in fruit and vegetable processing


     Abstract: China is a big vegetable producing country in the world, and the fruits are mainly fresh food. 70% of the fruits in developed countries have been processed. With the rapid development of fruit and vegetable processing, vacuum freeze-drying is an indispensable link in the processing of fruits and vegetables. Widely used in the drying of fruits and vegetables.


Application of freeze-dried carrots in freeze dryer


    In recent years, in addition to fresh food and juice, carrots have also been widely used in dried carrot products such as carrot puffed chips, carrot powder, etc. Carrot dried products have broad market prospects due to rich flavor, rich nutrients and easy carrying. .


    Chen Ruijuan et al. used solid phase microextraction/gas chromatography-mass spectrometry (SPME/GC-MS) to measure and analyze the aroma components of fresh carrots and four different dried carrot powders.


    The results showed that the main aroma of fresh carrots was cold and dry, which could retain the aroma components of fresh carrots to the greatest extent, and the content of esters increased. After hot air drying, medium-short wave infrared drying and vacuum drying, the terpene species are lost more, and aldehydes, ketones and other compounds are newly formed.
