Abstract

The present invention discloses a processing method for preserved tomatoes, which comprises the steps that tomatoes are used as raw materials and are selected and cleaned, the cleaned tomatoes are directly sliced, then steeped in clear solution of lime, rinsed, boiled in sugar, drained or dried, tested, packaged and prepared into the finished product. The present invention saves the processes of heat shocking and peeling in original processing method, and thus, on one hand, the time for processing the tomatoes into preserved fruit is shortened, on the other hand, the sliced tomatoes are favorable to steeping in the clear solution of lime, boiling in sugar and other subsequent processes, so the whole processing technology can be accelerated and simplified.

Description

Candied tomato producing process

The processing that the present invention relates to fruit or dish is preserved, and is meant a kind of candied tomato producing process particularly.

Various preserved fruits are liked by consumers in general deeply, because tomato belongs to the greengrocery of many moisture content, so it is still rare to be made into preserved fruit, but it has and is of high nutritive value and the characteristics of high yield, people are attempting it is made into preserved fruit always, exactly tomato is made into the research of preserved fruit (preserved fruit) aspect as the disclosed patent application of CN1033550, this preparation method exists complex process, the shortcoming of long processing time, as needs by blanching, just can carry out follow-up making behind the complicated technology of peeling, tomato is processed by integral body in addition, the technology of section is to be placed on before the finished product packing, and this also is a factor of long processing time.

For this reason, the present invention is directed to the shortcoming that above-mentioned making technique of candied tomato exists, propose another kind candied tomato producing process fast.

To achieve these goals, the present invention adopts following method: it is raw material that this method adopts with the tomato, raw material is selected, is cleaned, the tomato after cleaning is directly cut into slices, carry out respectively then the lime clear liquid soak, float clearly, candy, drain or drying, test package, finished product.

Because the present invention directly cuts into slices earlier to tomato to be processed, and the blanching in original processing method, the operation of peeling have been save, can shorten so on the one hand tomato is processed into the needed time of preserved fruit, tomato after the section helps also that the lime clear liquid soaks, the carrying out of candy and subsequent technique on the other hand, makes whole processing technology be able to fast, simplify.

Below in conjunction with embodiment, the present invention is described in further detail: the same with existing method, it is raw material that this method adopts with the tomato, raw material is selected, cleaned, picking out ripe tomato with a certain size cleans, in selecting, the tomato classification that maturity is more consistent is laid, so that in follow-up processing, can process to the different tomato of maturity, and clean this step, dirt on the tomato be removed, rinse water will keep clean haze-free, cleans with circulating water and is advisable.

Then be exactly slicing process, tomato after selecting and cleaning is directly cut into slices, it is the same substantially with thickness preferably it to be cut into size when tomato is cut into slices, common size of pressing tomato, each tomato can one be divided into four, one and be divided into five or six, why earlier section is that immersion of lime clear liquid and the technology afterwards that helps next step is carried out.

In fact the lime clear liquid soaks is exactly the technical process of tomato being carried out cure process, and the quantity of lime clear liquid needs lime clear liquid 3-5 kilogram for about per 10 kilograms tomato, and a GPRS soaks the lime clear liquid and cover tomato and cut into slices and get final product.The ratio of lime clear liquid is 10 to 3 to 10 to 5, and promptly the lime of joining 3 kilograms or 5 kilograms by 10 kilograms water mixes, and the soak time of tomato section in the lime clear liquid is 4 hours.Float clearly with that, the purpose of floating clearly is the lime on the tomato to be floated remove, and can float clearly once or several times, and also the easiest employing circulating water is advisable.The time of floating clearly can be determined on a case-by-case basis, generally can be about 4 hours.

Candy employing secondary is candy, the low syrup of once candy employing, approximately per 10 kilograms tomato needs 10 kilograms low syrup, the concentration of syrup is controlled between the 15-25%, and syrup also soaks the tomato section to cover and is advisable when candy, is controlled at 0.5 hour in the candy time, its temperature is controlled at 100 ℃ usually, can suitably stir in candy process, make it well-done and even, this is called for the first time candy.In the present invention, the candy employing height of secondary syrup, the concentration of the syrup that secondary is candy is controlled between the 55-75%, and syrup also preferably soaks lid with the tomato section, and the candy time of secondary preferably was controlled at 0.5 hour, and temperature is controlled at 100 ℃.After secondary was candy, the tomato section that can will boil after finishing drained or drying, gets final product about 4 hours in the ordinary course of things.Whole like this process is lasted 24 hours to 40 hours.And the whole process need of original common preserved fruit processing method is about ten days, so this method saves time, technology is simple, and unit needs blanching and peeling, and the tomato after the section absorbs sugar part easily than whole tomato and drains or dry.Wait to drain or drying after can be with the manufactured goods test package, dispatch from the factory.
