How to process citrus embryos
In each period of citrus fruit growth and development, due to uneven distribution of nutrients and other environmental conditions and other reasons, resulting in fruit drop phenomenon. From the point of view of processing and comprehensive utilization, it is necessary to make full use of fruit drop in different periods. For example, young fruit can be used to extract tangerine peel or hesperidin, which has a role in medicine. For more unripe fruits, because of the high acid content, sour taste, and lack of sweetness, they should not be eaten raw, usually processed into semi-finished salt embryos. Its processing technology is as follows:
1. Raw material processing: Before the fruit is dropped into the semi-finished product, it is best to remove the oleosome layer of the sweet orange. The greasy layer of the skin surface can be grinded off with a grinding wheel, and then the oil and water can be separated by a high-speed centrifuge to obtain the sweet orange aroma oil. The product can be obtained without affecting the salt embryo processing. Then use a simple machine to press the fruit embryo into a cake shape, that is, cut the fruit symmetrically into four small knife edges, and gently press it to form a cake. The acidity of the juice that comes out of the juice is higher and can be collected to make Citric Acid. Finally, the fruit embryo is sent to the marinade.
2. Salting: Use salt for 20-25% of the raw material, a layer of fruit layer of salt, top layer of fruit plus a layer of salt, and compacted with stones, so marinated for 3-4 weeks to end.
3. In the beginning of the sun: Remove the orange embryo from the marina and use natural drying method until the fruit surface appears salt frost. At this time, the water content is not uniform enough, does not meet the requirements, and the next process is needed.
4. Rejuvenation: The fruit embryos are piled up and covered for 1-2 days.
5. Re-sun: Sun 1-2 days.
6. Packaging: Use plastic film to seal the package from moisture. This semi-finished citrus embryo is further processed into orange cake for preservation of raw materials, and the finished product still has a strong citrus aroma.
According to the official rules, the food additive means any substance which are normally not consumed as a food in itself and that is not characteristic ingredient of food, having or not the nutritional value and through of which intentional addition to food for a technological purpose in during the manufacture, processing, preparation, treatment and packaging such food becomes part of them.
