冻干菜是一种新型冻干食品,是由新鲜蔬菜、肉食、水产、食用菌等快速冷冻后,再送入真空容器中经升华脱水而制成。冻干菜不仅保持了新鲜原料固有的色、香、味、形,同时最大限度地保留了内部的维生素、蛋白质等营养物质。食用时只需加水,即可在几分钟内复原为初始状态。冻干菜不要冷藏设备,密封包装后常温下能长期贮存、运输和销售,加之含水量只占5%,重量轻,故可大大降低经营费用。 Lyophilized food is a new type of freeze-dried food, which is quickly frozen by fresh vegetables, meat, aquatic products, edible fungi, etc., and then sent to a vacuum vessel and sublimated to dehydrate it. Lyophilized vegetables not only maintain the inherent color, aroma, taste and shape of fresh ingredients, but also maximize the internal retention of vitamins, proteins and other nutrients. Simply add water while eating, and it will return to its original state within minutes. The freeze-dried vegetables should not be refrigerated equipment, and they can be stored, transported and sold at room temperature for a long time after being sealed. The water content is only 5% and the weight is light, so the operating costs can be greatly reduced.
