Abstract
The present invention relates to a production technology for frozen dried lotus seeds. The production technology is characterized in that the production technology has the following process steps: (1) removing cores from picked lotus seeds by coring processing; (2) preparing a soaking solution according to the following proportion: 0.02 to 0.15% of EDTA, 0.1 to 0.3% of vitamin C and water as the rest; (3) soaking the cored lotus seeds in the soaking solution; (4) cleaning the lotus seeds, and then freezing the lotus seeds to make moisture in the lotus seeds frozen; (5) drying by vacuum sublimation at a low temperature: putting the lotus seeds with frozen moisture in bodies in a low temperature vacuum state to make the moisture directly sublimated into steam to be evaporated. The obtained frozen dried lotus seeds have the advantages of easy cooking, convenient eating, no browning and good taste.
Description
Technical field
The present invention relates to a kind of frozen-dried lotus seeds production.
Background technology
Building lotus is the quality product of Jianning County, Fujian special product, and about 4,000,000 dollars of year outlet wherein mostly is dried lotus seeds, mainly sells to the port, Australia, Taiwan, Japan and south east asia.For a long time, dried lotus manufacturing process is to pluck fresh lotus seeds to dry through logical core and make.Because dry the process technology parameter and can't grasp, so the dried lotus quality of making is uneven, the major defect of existence is surperficial shrinkage, and rehydration is poor, and appearance luster is gloomy, and product is difficult for boiling, lose the good to eat essence of its delicate fragrance, notable difference is arranged with bright lotus flavor quality.
Summary of the invention
The objective of the invention is to provide a kind of frozen-dried lotus seeds production, and the dried lotus product that this technology makes not only helps the normal temperature of long period to be preserved, and the product color light is pure white, can keep the peculiar taste of bright lotus, has rehydration preferably.
The present invention is undertaken by following process: (1) is with the logical core treatment process coring of plucking of lotus seeds warp; (2) by following proportioning obtain solution: disodium ethylene diamine tetraacetate 0.02-0.15%; Vitamin C 0.1-0.3%; Surplus is a water; (3) lotus seeds after logical core is handled of step (1) are inserted in the soaking solution of step (2) and soak, (4) are the freezing lotus seeds internal moisture ice crystalization that makes after cleaning; (5) vacuum and low temperature lyophilization: the lotus seeds of moisture ice crystalization in the body of step (4) gained are placed under the vacuum and low temperature state, moisture is directly distilled be gas, and evaporate.
The present invention one soaks owing to inserting in the soaking solution that adopts disodium ethylene diamine tetraacetate and vitamin C preparation through the lotus seeds after logical core is handled, therefore enzyme is lost activity, effectively prevent to cause the phenomenon of color and luster brown stain to take place because of the core tissue damage produces oxidizing ferment.The 2nd, owing to adopt refrigerating process, therefore can keep the fresh taste and the delicate fragrance of lotus seeds preferably.The 3rd, adopt the vacuum and low temperature lyophilization that the interior moisture of lotus seeds body is directly distilled and be gas, and evaporate.So than traditional dried lotus, the frozen-dried lotus seeds that technology of the present invention is made not only helps the normal temperature of the long period of lotus seeds to be preserved, and easily well-done, no brown stain is convenient to eat, and samples.
The specific embodiment
Below in conjunction with embodiment invention is given in specific descriptions.
The processing step of the embodiment of the invention is as follows: (1) is with the logical core treatment process coring of plucking of lotus seeds warp; (2) by following proportioning preparation soaking solution: disodium ethylene diamine tetraacetate 0.02-0.15%, vitamin C 0.1-0.3%, surplus is a water; (3) lotus seeds after logical core is handled of step (1) are inserted in the soaking solution of step (2) and soak; (4) the freezing lotus seeds internal moisture ice crystalization that makes after cleaning; (5) vacuum and low temperature lyophilization: the lotus seeds of moisture ice crystalization in the body of step (4) gained are placed under the vacuum and low temperature state, moisture is directly distilled be gas, and evaporate.
(1) prepares soaking solution by following proportioning in most preferred embodiment of the present invention: disodium ethylene diamine tetraacetate 0.1%, vitamin C 0.2%, water 99.7%; (2) lotus seeds being inserted the time of soaking in the soaking solution is 30 minutes; (3) vacuum in the low-temperature distillation drying process is 500-580mmHg, and temperature is 20-50 ℃, and the time is 6-12hr.
In order to improve the quality of products, above-mentioned lotus seeds adopt the lotus seeds that area, Jianning, Fujian Province produces to be advisable.
