Abstract
A preparation method of a lotus seed fast food which prevents fresh lotus seeds from turning raw, and the method comprises steps of materials selection, pretreatment, canning, sugar water adding, heating and exhausting, can sealing, sterilization and cooling. The preparation method is characterized in that the selected raw materials are fresh lotus seeds or quick-frozen fresh lotus seeds, the pretreatment is a steam treatment, that is, the selected fresh lotus seeds are washed, drained, and sent to a steam kettle, are steamed to ripe and cooled naturally to the room temperature, then the lotus seeds can be used for producing the lotus seed fast food. The preparation method has low equipment requirement and strong operability, and can effectively solve the revival problem that the fast food made from fresh lotus seeds turns raw and fully maintains smooth, soft and mouth melting taste and nutrition value of the fresh lotus seeds, therefore, the preparation method is fit for the large-scale industrialized production of fresh lotus seed fast food. In term of the flavor, the cooked fresh lotus seed has fresh, crisp and flaky taste as well as delicious sweet juice; however, the cooked dried lotus seed tastes glutinous without special flavor, and can not provide the faint scent of the fresh lotus seed.
Description
Technical field
The present invention relates to the production method of lotus seeds instant food, prevent that particularly bright lotus from returning the production method of living lotus seeds instant food.
Background technology
Various lotus seeds instant foods in the market are that raw material are made with dried lotus all,
And do not go out on the marketExisting is raw-material lotus seeds instant food with bright lotus; Its reason just be starch after the gelatinization under room temperature or lower temperature; The starch molecule that originally is disordered state is arranged through hydrogen bond again in order, forms the highly crystalline body that is difficult to rehydration, and this process is the life of returning of starch; And bright Nelumbo is in high starch food; The special nature of the starch that it contains very easily loses practical value because lotus seeds return living after traditional handicraft is produced, be the development of the lotus seeds instant food of raw material thereby hindered with bright lotus.
Summary of the invention
The invention provides and a kind ofly prevent that bright lotus from returning the preparation method of living lotus seeds instant food; Utilize the method for vapour cooking that bright lotus is handled; Prolonged the storage time of lotus seeds instant foods, bright lotus can not occur returning living phenomenon, and having promoted with bright lotus is the development of the food processing industry of raw material.
The technical solution adopted for the present invention to solve the technical problems is: a kind ofly prevent that bright lotus from returning the preparation method of living lotus seeds instant food; Comprise and select materials, preliminary treatment, batching, tinning, add syrup, thermal exhaust, envelope jar, sterilization, cooling; It is characterized in that: (1) is described selects materials: select fresh lotus seeds, perhaps the bright lotus of quick-frozen; (2) described preliminary treatment is that vapour cooking is handled: the cleaning that will select for use, the bright lotus after draining are sent in precooker or the steamer, through vapour cooking handle well-done after, through cooling off naturally or cold wind is cooled to room temperature.
Remaining technology comprises and selects materials, batching, tinning, adds the general processing technology that syrup, thermal exhaust, envelope jar, sterilization, cooling are existing production can or beverage.
It is low that the present invention has equipment requirements, solved bright lotus and returned living problem, and the lotus seeds instant food of being produced has and is of high nutritive value the characteristics that mouthfeel is good.Aspect nutrition, the superoxide dismutase in the bright lotus (SOD) still can keep 80% activity in cold storage after 1 year, exceeds 1 times than the SOD activity of dried lotus.SOD has the removing free radical, keeps the active oxidation balance, keeps membrane structure, delays the effect of organ aging course.On local flavor, bright lotus boil the back bright, crisp, crisp, soup juice is fresh and sweet, and is aromatic good to eat; It is glutinous that dried lotus is boiled back mouthfeel powder, and its flavor is average, does not have the delicate fragrance local flavor of bright lotus.
The specific embodiment
A kind of mode of production of lotus seeds instant food prevents that particularly bright lotus from returning the production method of living lotus seeds instant food.Its concrete production method is following:
1, follow these steps to produce the lotus seeds instant food:
(1) washes bright lotus: be placed on the bright lotus of bright lotus or quick-frozen in the water and clean (wherein the bright lotus of quick-frozen changes ice fully), clean bright lotus to be picked up after finishing and drain water.
(2) cook bright lotus with steam: be placed on bright lotus in the precooker (or steamer), extremely well-done fully with vapour cooking.Attention: can not be placed on poach in the pot to bright lotus; And necessary water proof boiling; And the length of digestion time is to guarantee bright lotus or to thaw bright lotus well-done being as the criterion fully; General digestion time can also can prolong or shorten digestion time according to the difference of once boiling lotus seeds amount at 5-40 ± 1 minute (specific embodiment is as shown in table 1).
(3) cooling: place the ventilation to the bright lotus after well-done through boiling and naturally cool to normal temperature or room temperature, perhaps use cooler to carry out cold wind and be cooled to normal temperature or room temperature.Attention: can not use the cold water cooling, and want continuous cool to room temperature.Be generally cool time 10-40 minutes.
(4) batching: prepare syrup or non-sugar aqueous solution by the state food standard or according to the needs of various tastes, mix the rock sugar aqueous solution of National standard or industry standard like water, rock sugar, honey, food additives etc.Also can allocate various taste syrup arbitrarily or in syrup, add other edible compositions arbitrarily according to various needs.
(5) tinning or bottling: steaming well-done bright lotus or other food solid contents tinning or bottle back (according to the solid content volumetric(al) standards of the tinned food of national standard or the tinning of solid content volumetric(al) standards or the bottling of tinned drink, the content of the solid content of tinned drink also can be confirmed arbitrarily) in proportion; In jar or bottle, be full of the rock sugar aqueous solution that has prepared or the aqueous solution that contains other additives again.
(6) thermal exhaust: get rid of unnecessary air in jar (bottle) through the mode of heating.
(7) envelope jar (bottle): seal jar (bottle) with tin seamer (bottle capper), assurance jar (bottle) can not be leaked gas and leaked.
(8) wet sterilization: be placed on the can that installs the bright lotus and the rock sugar aqueous solution in the wet sterilization pot and use wet sterilization, steam pressure is controlled at 0.1-0.12MPa, and sterilizing time is 20～40 minutes.
(9) cooling: the can to after the sterilization is cooled to normal temperature, and water-cooled but, air cooling or cool off naturally all can.
(10) packing: can is printed the date or labels, and the vanning of check back.
2, in above-mentioned production process, most important technical characterictic is: bright lotus has been carried out preliminary treatment, be about to bright lotus and carry out vapour cooking in advance, rather than the bright lotus of traditional poach is perhaps directly boiling through wet sterilization in the bright lotus threading jar; Bright lotus is carried out nature cooling or air cooling to normal temperature (room temperature) after well-done with vapour cooking, and can not use water-cooled.
Table 1
| Bright lotus amount (kg) | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 | 0.5 |
| Digestion time (minute) | 5 | 10±1 | 15±1 | 20±1 | 25±1 | 30±1 | 35±1 | 40±1 |
