Shatian pomelo fruit processing technology
Shatian pomelo is a fine variety of pomelo, with tender tenderness, juicy, sweet honey, long natural storage and other characteristics. In production, Shatian pomelo should be treated after harvest to reduce decay, extend shelf life and improve quality, and increase economic income. I. Timing of harvesting and fruit picking is generally selected in mid-late and late November. The standard of fruit picking is that the peel color changes from green to yellowish green and the epidermis is smooth; the fruit picking time is selected after the dew is dry, usually after 7 am to 8 am . 7 to 10 days before fruit picking can not be watered, in case of rain weather, it is best to choose the rain stopped after 7 to 10 days of sunny fruit picking.

To cut the fruit pedicure, do not touch the hand, do not hurt the skin as the standard. Cut lightly when cutting fruit. Third, fruit grading Shatian pomelo is based on fruit size, color, shape, maturity, pests and diseases and mechanical damage and other conditions. According to the current state of the fruit weight size classification, can be divided into special, A, B, C, D and 6 levels outside the class: 1.5 kg or more for the special grade, 1.25 to 1.5 kg for the Class A, 1 to 1.25 kg for the B Grades, 0.75 to 1 kilograms for the C level, 0.5 to 0.75 kilograms for the D level, other for the level of fruit. According to the experience of Meizhou fruit growers, 1.25 to 1.5 kg of Shatian Pomelo has a good taste (mellow and refreshing honey flavor). Therefore, Shatian has a weight of 1.25 to 1.5 kilograms, is in good shape, has a yellowish-green skin, and is smooth on the surface of the skin. It has no mechanical damage and pests and diseases. Pomelo is classed as a superior product, because this Shatian Pomelo is of medium size, good taste (sweet and crunchy) and beautiful appearance. Fourth, fruit disinfection, preservation, storage of fruit disinfection, preservation can use the southern ideal of the preservatives such as green, can also be used carbendazim 1000 mg / l and 2.4d200 ~ 250 mg / l of liquid for disinfection, preservation. In special years, such as early drought and late rain, Shatian pomelo has a high rot rate, and it is better to use a preservative with an ideal effect. Fruits must be pre-hidden before they are stored, and they are pre-stored with callus, sweat, and cooling to reduce the effect of fruit temperature. Pre-hidden is to sterilize or rough-select the fruits that have just been harvested. After severe mechanical damage, pests and diseases, put in a well-ventilated room that prevents the intrusion of moist air, direct sunlight, and dry ground. The fruit heap should not be too high. After 20 days of pre-storage, it can be packaged. Generally, there is mechanical damage, and if the disease is not packaged, it should be sold on the spot. The packaging uses polyethylene film bags as packaging bags. It has the effects of softness, heat preservation, moisture retention, and fresh air conditioning. It is odorless and the fruits are resistant to storage after packaging. Place the packed Shatian pomelo on a wooden stand or iron frame that has been set up. After each layer is piled up, piling the fruit over the pores between the fruit and the fruit can stack 4 to 5 layers. This can be ventilated and air-permeable for inspection. If rotten fruit does not infect each other, it will affect other fruits. Storage environment conditions are preferably maintained at about 10°C and relative humidity at 90%. Carbon dioxide content is maintained at less than 1% and oxygen is maintained at about 5% to 10%. 5. Packing and Transportation The packaged Shatian pomelo is shipped in cardboard boxes. Can be divided into large and small packaging forms, fruit box is best to have ventilation holes, conducive to ventilation and ventilation, in the transport process, to do fast, fast, fast unloading, and pay attention to gently, reduce mechanical damage.
