Storage and processing of lily

First, storage. The newly harvested lilies have high moisture content, exuberant breathing, and easy to mildew if they are not kept well, which affects their efficacy and value. If the lily is stored in fine sand, it can keep both fresh and quality.

1. Raw material treatment before storage: freshly harvested lilies should be placed in a shaded place to avoid sunlight, so as to prevent discoloration and dehydration of outer scales. After digging up the lily bulb, the soil, stem and fibrous root should be removed in time, and then the complete lily bulb with white, large, fresh and disease-free bulb should be stored in different stages.

2. Operation points of sand storage method: ① builds a moderate-sized pool or pit with bricks in a cool house or basement according to the number of lilies hidden. ② evenly spread 6-8 cm thick fine sand at the bottom of the pond or pit, then put the fresh lily bulb on the sand, then cover it with 3-4 cm sand, and then put a layer of lily bulb on the sand layer, stacking it repeatedly, with a stack thickness of about 1 meter. The sand covered with lilies should be slightly dry, so as not to cause lilies to take root and mildew due to excessive humidity. ③ is covered with 20-30 cm thick soil (or sand or straw) around and at the top of the lily. be careful not to be too thin, otherwise it is easy to make the lily bulb dehydrated and stale. The suitable storage temperature of ④ is 6-11 ℃. It should be checked frequently during storage to prevent lily from heating and mildew. If fever occurs, it should be re-stored according to the above method.

Second, processing. If the lily is not unused, it can be processed into a dry film. The methods are as follows:

1. Peeling: fresh slices can be peeled by hand or cut across the base of the bulb to separate the scales. When peeling, due to different varieties, the texture of the scales is also different, therefore, different varieties should not be mixed and peeled, and the same variety should be packed with scales, middle scales and chips according to the location of the scales, then wash and drain.

2. Bubble flakes: boil the water, classify the pretreated scales into the pot, and put an appropriate amount of scales in each pot to facilitate turning, and the scales are submerged by water. When bubble flakes, the firepower should be uniform, and the time of each pot should be 5-10 minutes (after the scales are put into the pot, wait for the water to boil again). When the edges of the scales are soft and there are micro-cracks on the back, remove them quickly, rinse them in clean water, wash the mucus and remove them to drain. Each pot of water can be continuous bubble 2-3 times, such as water turbidity, that is, change the water, otherwise, affect the scale color, reduce the quality.

3. Exposure: bubble tablets can not be accumulated after rinsing, and should be spread out in time. When the scales are 60% dry, turn the sun once until fully dry. If the sun is turned too early, the scales are fragile and of poor quality. If encounter cloudy day, should put scale spread in indoor ventilation place, avoid accumulation, in order to prevent mildew, also can use baking method to dry.

4. Packaging: the dried lily slices are graded, with white, complete, large and thick scales as the top grade, which is suitable for export, and then packed in food plastic film bags weighing 500 grams each, packed in cartons or fiber bags and stored in dry and ventilated indoor storage to prevent damp mildew, moth and rat bites, or contract packaging when exported.
