Abstract
The invention provides a preparation method for a vacuum freeze-dried lily piece. The preparation method is characterized by comprising the following steps: 1, selecting raw material of lily; 2, washing through clear water or washing through clear water after the lily is put into a corresponding solution for disinfection; 3, cutting to remove the stem and root part of the lily through a corresponding tool; 4, rupturing the membranes of the scales of the lily by using a manual or mechanical method; 5, stripping off scales, and washing through clear water again; 6, putting into a quick-freezing chamber with the temperature of minus 40 to minus 30 DEG C for quick-freezing; 7, putting the quick-frozen lily into a vacuum chamber for drying for 6-18 h, adjusting temperature and vacuum degree in the vacuum drying process so as to prevent dried scale from being cracked or forming fish scales, and enabling the water content to meet quality standards; 7, putting the dried lily into a damp-proof packing bag, so that the product of the vacuum freeze-dried lily piece is obtained.
Description
Technical field
The present invention relates to a kind of preparation method of vacuum freeze-drying dried lily bulb, is that a kind of employing lily is raw material, produces dried lily bulb product and preparation method thereof.Belong to processing of farm products field.
Background technology
Lily is Chinese traditional local speciality, China produces dried lily bulb product and preparation method thereof take airing, oven dry etc. as main at present, dried lily bulb nutritional labeling, the functional component loss of producing are larger, lily slice in dry processing process, produces brown stain blackening phenomena and shape is shunk, and rehydration time was at 4-6 hours.Vacuum freeze-drying dry technology is advanced in the world vegetable drying technology, adopt the dry lily nutritional labeling of vacuum freeze-drying, functional component to lose less, color and luster nature milky, attractive in appearance, drying efficiency is high, rehydration time was at 10-20 minutes, convenient and swift, and retain the original local flavor of lily and shape.
Summary of the invention
The object of the invention is exploitation a kind of take fresh lily bulb as raw material, through vacuum freeze-drying dry technology, make and can retain compared with multiple nutritive components and the original local flavor of lily and shape, the natural milky of color and luster, dried lily bulb product attractive in appearance.The process of manufacture dried lily bulb product, its technological principle is to select, cleaning and sterilizing, go stem, root, scale puncture rupture of membranes, strip off scale, cleaning, quick-frozen, vacuum drying, adjusting temperature vacuum, packing through raw material, finally make vacuum freeze-drying dried lily bulb product, its main feature is the rupture of membranes that punctures through scale, regulate temperature vacuum, prevented and treated dry rear lily bud scale and easily bubbled, break or form flap.
Its technological process and process control condition are as follows:
One, the technique of getting the raw materials ready:
(1) select materials: preferably lily is for subsequent use;
(2) equipment: equipment modulation is normally for subsequent use;
Two, clean, sterilize
Three, raw material processing
Go stem, root, scale puncture rupture of membranes, strip off scale, cleaning
Four, quick-frozen
Put into-30 ℃ to-40 ℃ of quick freezing repository quick-frozens
Five, vacuum drying
The good lily of quick-frozen is put into the vacuum in-bin drying 6-18 hour of vacuum 50-100Pa, easily break or form flap for preventing and treating dry rear scale, early stage, drying plate temperature should be controlled at 70-80 degree; Mid-term, temperature should be controlled at 60 degree, and latter temperature should be controlled at 40-50 degree.
The dried lily bulb of making by above-mentioned technological process and controlled condition, can retain compared with multiple nutritive components and the original local flavor of lily and shape, color and luster nature milky, attractive in appearance, has improved the rehydration time of dried lily bulb simultaneously.
