(4) and (3) after preparing the syrup, coating sugar on the formed chocolate in a water chestnut type sugar coating machine, drying, and transferring to a polishing machine to polish the chocolate, so that the chocolate is polished.
8. A method of making a low energy chocolate according to claim 7 wherein: in the step (1): 10ml of the cellulose suspension was freeze-dried at-60 ℃ for 48h to obtain a cellulose powder, which was added to a 5% triglyceride suspension in a mass ratio of cellulose to triglyceride of 2: and 3, oscillating and reacting for 3 hours at 40 ℃, standing for 1 hour, performing ultrasonic dispersion, centrifuging to remove the lower-layer water phase, and dispersing the oil phase for 1min by using an ultrasonic cell crusher to obtain the cellulose modified triglyceride.
9. A method of making a low energy chocolate according to claim 8 wherein: in the step (2): placing 5g of polyphenol into a reaction vessel, and adding the polyphenol into the reaction vessel in a mass ratio of 1: 8, then stirring at 600r/min, heating to 60 ℃, adding 0.3g of reaction catalyst, namely sodium bicarbonate, and then slowly and gradually adding the mixture into a reaction container, wherein the mass ratio of the mixture to the polyphenol is 1: 3, reacting for 2 hours, washing for several times by using dilute hydrochloric acid and distilled water after the reaction is finished, removing the catalyst and the redundant polyphenol, separating to remove a water layer, adding an excessive dehydrating agent for drying and filtering, and finally concentrating the organic phase under a vacuum low-temperature condition to remove ethyl acetate to prepare the acylated polyphenol.
10. A method of making a low energy chocolate according to claim 9 wherein: in the step (3):
firstly, mixing powdered sugar and talcum powder in a proportion of 1: 4, decocting syrup with the concentration of 3mol/ml, and keeping the temperature at 35-40 ℃ for later use;
secondly, mixing gelatin, granulated sugar and monoglyceride according to the weight ratio of 0.25: 2.5: 0.4, adding proper water, decocting to prepare uniform mixed liquid, filtering, and keeping the temperature at 35-40 ℃ for later use;
thirdly, coating sugar on the formed chocolate in a water chestnut type sugar coating machine, sprinkling 10-20 ml of syrup in the rolling process of the chocolate, and uniformly coating the surface of the chocolate due to friction; the granulated sugar and the talcum powder can form a hard shell on the surface of the chocolate after being dried;
and (IV) coating and polishing the sugar-coated and dried semi-finished product by using the mixed solution to obtain a finished product.
