Description

A kind of no sulphur slice food made from Amorphophallus rivieri and its processing method
Technical field
The invention belongs to a kind of slice food made from Amorphophallus rivieri, and in particular to a kind of no sulphur slice food made from Amorphophallus rivieri and its processing method.
Background technology
Konjaku also known as mill taro, terrible taro are Angiospermae, monocotyledon, Araeceae, thorn taro subfamily, Ci Yu races Herbaceos perennial.
The polyphenol oxidase activity of fresh Amorphophallus rivieri is very high, and enzymatic browning is extremely serious in drying process, and dried product color is very black. Currently, for the browning phenomenon for inhibiting in konjaku drying process, method is as follows:After fresh Amorphophallus rivieri cleans slice, burn sulphur, uses smog Slice food made from Amorphophallus rivieri is smoked, is then dried, dry plate is obtained, then crushes to obtain konjaku flour.The konjaku handled using sulphuring is dry Piece(Angle), the dried products sulphur residual quantity such as konjaku flour reach 800-1000ppm or more, influence konjak food safety, while sulphuring It polluted environment.Therefore, in the process of konjaku dried product, sulphuring processing not only pollutes environment, also compromise consumer and The health of processing staff.
Invention content
The object of the present invention is to provide a kind of processing methods of no sulphur slice food made from Amorphophallus rivieri, using fresh Amorphophallus rivieri as raw material, by specific Processing method obtains no sulphur slice food made from Amorphophallus rivieri.
The invention also discloses made from specific processing method without sulphur slice food made from Amorphophallus rivieri.
In order to achieve the above object, the technical solution adopted by the present invention is:A kind of processing method of no sulphur slice food made from Amorphophallus rivieri, including such as Lower step:
1), konjaku is washed;
2), to konjak corm carry out rubbing leather processing;
3), konjak corm is sliced, is collected;
4), with steam blanching destroy the enzyme treatment is carried out to slice food made from Amorphophallus rivieri, to inhibit polyphenol oxidase activity;
5), with konjaku flour slice food made from Amorphophallus rivieri is handled, so that slice food made from Amorphophallus rivieri surface is wrapped up in attached one layer of konjaku flour;
6), slice food made from Amorphophallus rivieri is subjected to microwave drying.
Preferably, step 1)Konjaku is washed using fruit-vegetable cleaner.
Preferably, before being washed to konjaku, diameter is selected to be more than 5cm and without pest and disease damage, rotten konjak corm.
Preferably, step 2)Rubbing leather processing is carried out to konjak corm using husking machine, rubs skin portion with the hands, it is dry to reduce konjaku The browning degree of product.
Preferably, step 3)Konjak corm hypodermic layer and core layer are sliced respectively, using slicer by konjak corm into Row slice, hypodermic layer slice thickness are 8mm-10mm, and core layer slice thickness is 12mm-15mm, after slice, hypodermic layer and core The slice food made from Amorphophallus rivieri of layer is collected respectively
Preferably, the steam generated respectively with fruits and vegetables blanching machine carries out at blanching enzyme deactivation the slice food made from Amorphophallus rivieri of hypodermic layer and core layer Reason, to inhibit polyphenol oxidase activity, the slice food made from Amorphophallus rivieri steam enzyme deactivation parameter of hypodermic layer to be:Slice food made from Amorphophallus rivieri single layer is laid, and every layer is a piece of, The saturated vapor that temperature is 100 DEG C -120 DEG C, processing time 4min-5min;The slice food made from Amorphophallus rivieri steam enzyme deactivation parameter of core layer is:Evil spirit Taro piece single layer is laid, and every layer a piece of, the saturated vapor that temperature is 100 DEG C -120 DEG C, processing time 3min-4min
Preferably, step 6)Slice food made from Amorphophallus rivieri is subjected to microwave drying, slice food made from Amorphophallus rivieri, slice food made from Amorphophallus rivieri list are dried using fruits and vegetables microwave dryer Layer is laid, drying time 60min-90min.
Slice food made from Amorphophallus rivieri made from processing method using above-mentioned no sulphur slice food made from Amorphophallus rivieri, moisture content 8-12%.
Beneficial effects of the present invention:(1)Very high, the of the invention slice food made from Amorphophallus rivieri of konjaku dried product sulphur residual quantity at present(Konjaku is dry Product)Because without addition sulphur in process, in addition the microwave drying time is short, the content of sulfur dioxide generated in drying process Also extremely low, therefore the present invention can obtain no sulphur konjaku dried product completely, and the evil spirit of no sulphur is provided for the processing of konjak food Taro dried product raw material.
(2)The basic principle that the present invention uses is:According to konjak corm different parts(Surface, hypodermic layer and core layer)It is more The height of phenoloxidase activity inhibits enzyme activity using the saturated vapor blanching slice food made from Amorphophallus rivieri of high temperature and humidity, eliminates brown stain.
(3)After testing, using processing method of the present invention, slice food made from Amorphophallus rivieri, sulfur content are obtained(In terms of sulfur dioxide)For 20- 30ppm, national standard are less than 200ppm, and sulfur content of the present invention is extremely low far below national standard sulfur content.
