Abstract
An instant dewatered rice is prepared through cooking rice, quick freezing, vacuum dewatering and moisture-proof packing. Its advantage is short time for soaking it in hot water at the temp higher than 60 deg.C (3min).
Description
The present invention relates to a kind of instant-rice and preparation method thereof, specifically be a kind of that boil, with Lyophilisation technique for making slough moisture, can dehydrated cooked rice instant, that be furnished with vacuum dehydration soup dish piece and preparation method thereof.
Rice is the staple food in our daily life, the wide consumer group is arranged, but its boiling time is longer, living with modern fast pace, some is inharmonious, though prior art also has the instant-rice of development therefrom, what adopt is the heated-air drying dewatering, and the color and taste of rice, nutrition comparatively fresh rice all have loss, and be simple rice, be not furnished with the soup dish.
The purpose of this invention is to provide a kind of be furnished with solid vacuum dehydration soup dish piece, adopt dehydrated cooked rice that the Lyophilisation technique for making dehydration forms, can instant.
The present invention finishes by following scheme:
A kind of instant dehydrated cooked rice and preparation method thereof, its manufacturing process mainly may further comprise the steps:
1, the shortening of rice: rice is eluriated back dipping about 10 minutes, under high pressure or normal pressure, fully boil it ripe.
2, sabot: well-done rice is contained in the container of definite shape.
3, quick-frozen: the rice that will install dish is put into temperature and is lower than-18 ℃ of quick freezing repository quick-frozens more than 8 hours, so that-18 ℃ of low sons of the central temperature of each entity.
4, vacuum dehydration: the rice that quick-frozen is good is put into the vacuum storehouse that vacuum reaches below the 100Pa, condenser temperature reaches below-40 ℃ and is dewatered, dehydration is by being that the process curve that parameter is set carries out with time and temperature, so that the water content of each entity is not more than 3%.
5, damp-prrof packing: the grain of rice pine of rice that will take off water from the back with the vacuum dehydration soup dish piece that is equipped with pack in the lump in the vacuum damp-proofing packing finished product.
Compared with prior art, effect characteristics of the present invention are mainly reflected in:
1, utilization vacuum freezedrying dehydration technique makes the dehydrated cooked rice taste, the nutrition that make all keep the same with new cooking rice.
2, the instant rehydration is fabulous, and brewed in hot water just can reach the state of fresh rice more than 60 ℃ in 3 minutes.
3, be furnished with solid vacuum dehydration soup dish piece, can with rice brew simultaneously edible, more convenient more nutrition.
Embodiments of the invention are as follows:
1, the shortening of rice: get 5 kilograms in refining rice, eluriate clean and ripe with cold water dipping 10 minutes boiling under normal pressure.
2, sabot: the rice that boiling is ripe is contained in certain container by every part of 250g.
3, quick-frozen: the rice that will install dish is put into quick freezing repository quick-frozen 12 hours, the central temperature of each entity is reached-20 ℃.
4, vacuum dehydration: the rice that quick-frozen is good is put into vacuum and is reached 60Pa, condenser temperature and dewater for-40 ℃ vacuum storehouse, and dehydration is pressed
Process curve carry out so that the water content of each entity reaches below 3%.
5, damp-prrof packing: the grain of rice pine of rice that will take off water from the back with the vacuum dehydration soup dish piece that is equipped with pack in the lump in the vacuum damp-proofing packing finished product.
Claims (3)
1, a kind of instant dehydrated cooked rice, it is characterized in that with rice boil back utilization Lyophilisation technique for making be dehydrated into can instant the solid shape.
2, instant dehydrated cooked rice as claimed in claim 1 is characterized in that it is furnished with the vacuum dehydration soup dish piece that can brew edible solid shape simultaneously.
3, a kind of preparation method of instant dehydrated cooked rice is characterized in that this preparation method mainly may further comprise the steps:
