(1) Harvesting: The suitable harvesting time of the lemon fruit is when the peel color changes from dark green to light green, which is both beneficial to storage and maintaining fruit quality. It can also be judged based on the fruit juice content, and the fruit juice content of 30% is the minimum standard for lemon harvest.
Harvesting should be carried out with fruit and scissors. In order to reduce mechanical injuries, fruit stems should be preserved, but they should be as short as possible to avoid new mechanical damage during transportation. Picking should also remove fruit, malformed fruit, and hurt fruit. Rotten fruit that has no applied value should be collected and destroyed.
(2) Pre-cooling: After harvesting the fruit, it should be pre-stored and pre-cooled in time. This not only can release field heat, but also can make the fruit that has been affected but has no symptoms to show symptoms so as to eliminate. The method can be used Air-cooled, water-cooled.
(3) Grading, washing fruit, and waxing: The fruit should be graded according to size, color, and fruit type. The grading standard can be self-made, or it can adopt the standards of the country or related exporting countries to improve its commerciality. Washing the fruit can remove dust on the surface of the fruit, improve the finish, reduce pollution, and reduce the decay rate.
Waxing, also known as paint treatment, is a common method used by developed countries to improve the commercial quality of fruit. Commonly used paints include paraffin wax, pine resin, shellac, and water-soluble paraffin made of paraffin wax. To ensure food safety, many natural coating materials have been used, such as starch, protein, vegetable oils, etc. Waxing methods include dipping, brushing, and spraying. Waxing should pay attention to the following points: 1 material safety non-toxic; 2 coating thickness due to variety characteristics, different types and characteristics of different coatings, the specific should be based on the experimental basis; 8 coating should be uniform and appropriate; 4 waxing is the fruit harvesting An auxiliary measure for commercialization within a certain period of time is only suitable for short-term storage or pre-listing treatment to improve commodity quality, and long-term storage should be prudent.
