Therefore, the present invention is coated with chocolate to be wrapped in Li Ren surface, or is evenly mixed and made into Li Ren chocolate with chocolate by Li Ren is broken, thereby makes Li Ren chocolate have the nutrition of Li Renhe chocolate simultaneously, has also retained local flavor separately simultaneously.
Li Ren chocolate provided by the invention is made by following steps:
(1) slaking is shelled: in the side cutout of Chinese chestnut, but do not injure Li Ren; Chinese chestnut is put into 80~100 ℃ of water and keep 20~40s; Shell, go capsula interna clothing, obtain half-mature Li Ren;
For keeping complete Li Ren and being convenient to Chinese chestnut, shell, therefore before slaking in Chinese chestnut side cutout, make chestnut shell fracture but do not injure Li Ren; Chinese chestnut is put into hot water 20~40s, makes the outer gelatinization of Li Ren, and with capsula interna ginning outturn from, when Chinese chestnut is when in hot water, the time is greater than 40s, the complete gelatinization of starch in Chinese chestnut, Li Ren matter is soft frangible, is not easy to shelling or removing capsula interna clothing of Chinese chestnut; When Chinese chestnut is when in hot water, the time is less than 20s, the separation degree of Li Ren and capsula interna clothing is not enough, in the process of removing capsula interna clothing, can cause the breakage of Li Ren, therefore, it is 20~40s that the present invention selects the time of Chinese chestnut in hot water, preferred 30s, meanwhile, due in the present invention, the time of Li Ren in hot water is only 20~40s, heat time is short, therefore can not cause browning of chestnut, save the operation that in maturing process Li Ren protects look, the operation of not only simplifying, and the resource of saving, reduced the content of additive in Li Ren.Described hot water is that temperature is the water of 80~100 ℃, when water temperature is less than 80 ℃, its temperature deficiency so that Li Ren gelatinization and with capsula interna ginning outturn from; When temperature is greater than 100 ℃, can destroy the local flavor of Li Ren, therefore, it is 80~100 ℃ that the present invention selects the temperature range of hot water.
(2) rinsing: by half-mature Li Ren water rinse 1~5 time obtaining in (1); The chestnut shell that may be stained with on Li Ren and capsula interna clothing are washed away.
(3) freezing: the half-mature Li Ren after rinsing in (2) is placed to 1~5h under-20~-15 ℃ of conditions;
Under normal temperature condition, easily there is rotten and brown stain in the Li Ren after shelling, this is the enzyme effect due to Li Renzhong, yet under cryogenic conditions, the activity of enzyme can significantly reduce, when enzyme is in low temperature environment when more than 5 hours, organized enzyme number is few, can guarantee that brown stain does not occur Li Ren in subsequent operation step, but the cryogenic freezing time is while being greater than 5 hours, can expend a large amount of Production Times and the energy, therefore select the cryogenic freezing time to be less than 5 hours, and when enzyme keeps below 1 hour in low temperature environment, organized enzyme number is too much, can cause Li Ren in subsequent operation step that brown stain occurs, thereby cause the shade deviation of Li Ren chocolate, therefore, the present invention is placed in low temperature environment 1~5 hour by half-mature Li Ren, to realize blunt enzyme and to prevent non-enzymatic browning, simultaneously, because chestnut starch content is high, under not freezing state, easily chopping, therefore the Li Ren after K cryogenic treatment is easy to stripping and slicing processing, in addition, Li Ren is after K cryogenic treatment, and wherein contained moisture can be formed ice crystal, when fried, and direct boiling distillation, thereby the oily purity of use that can be in frying course and the crisp brittleness of Li Ren.
(4) boiling: the half-mature Li Ren after freezing in (3) is put into boiling water, until boil completely, obtain ripe Li Ren, make Li Ren edible.
(5) dry: the ripe Li Ren obtaining in (4) is placed in to dry environment, to moisture evaporate to dryness, reduce the moisture of fried front Li Ren, make Li Ren surface there is no moisture, so that heat can enter Li Renzhong fast in follow-up frying process, thereby make Li Ren palatable crisp.
(6) fried: dried ripe Li Ren in (5) to be placed in to the edible oil of 110~130 ℃ of temperature, frying 8~12min;
The tolerable temperature of the nutriment of Li Renzhong is 130 ℃, when oil temperature is during higher than 130 ℃, the nutriment of Li Renzhong can be destroyed falls, and when oil temperature is during lower than 110 ℃, can cause because temperature is too low fried time lengthening, and then cause oil content in Li Ren to rise, both the nutrition that had destroyed Li Ren also destroys the mouthfeel of Li Ren, therefore, it is 110~130 ℃ that the present invention selects oil temperature, is preferably 120 ℃; Under this oil temperature, frying overlong time, while being greater than 12min, can cause Li Ren surface really up to the mark, make Li Ren mouthfeel poor, when the frying time is less than 8min, Li Ren frying is not enough, and Li Ren inside still matter is soft, mouthfeel is not crisp, thus the present invention to select the frying time be 8~12min, be preferably 10min.
(7) oil strain: the ripe Li Ren after fried in taking-up (6), be placed on 1~5min on filter paper for oil, preferred 3min, remove the unnecessary oil in Li Ren surface, when Li Ren surface is covered with oil film, the adhesive force between itself and chocolate reduces, thereby easily makes external layer of chocolate come off, and after the unnecessary oil in Li Ren surface is removed, chocolate catsup just can be combined closely by Li Ren.
(8) cooling: the ripe Li Ren after oil strain in (7) is carried out air-cooled, or place 1~3h in dry environment, preferred 2h, make Li Ren completely cooling, so that the better combination of Li Ren and chocolate catsup, because Li Ren volume in cooling procedure may reduce to some extent, and its temperature when selling is normal temperature, therefore Li Ren is cooled to normal temperature and be combined with chocolate catsup and can prevent the cracking on the chocolate top layer that causes because of the variation of Li Ren volume or come off.
(9) chocolate catsup processing: will chocolate catsup fine grinding, under 40~50 ℃ of conditions, be incubated after refining, make that chocolate catsup is moisture is no more than 1%, so that chocolate catsup is combined more closely with Li Ren.
(10) wrapped chocolate catsup: by the chocolate catsup making in (9) evenly on the wrapped ripe Li Ren to making in (8), wherein, the thickness of chocolate catsup is 2~3mm, be preferably 2.5mm, or by ripe Li Ren and chocolate catsup according to weight ratio 1:(1~5), be preferably 1:(2~4), evenly mix, make ripe Li Ren and chocolate cream material mixture.
(11) solidify: by the Li Ren after wrapped chocolate catsup in (10) or by the broken chocolate cream of Li Ren, be placed in mould, then mould is placed in to 0~8 ℃, be preferably under 5 ℃ of conditions, preserve 10~20min, be preferably 15min, solidify to chocolate, make the chocolate crude product of Li Ren.
(12) polishing: the chocolate crude product of the Li Ren after solidifying in (11) is taken out, the uneven surface of chocolate is revised, until surperficial rounding.
And need to after freezing, thaw while making the Li Ren chocolate of Li Ren and chocolate mixed type, so that by Li Ren stripping and slicing, and it is freezing after Li Ren stripping and slicing, to carry out secondary, to remove more up hill and dale the moisture of Li Renzhong, is convenient to follow-up frying course.
