Fig. 1 represents the technological process of production of high-quality Sugarless high-fibre low-energy moon cake provided by the invention.Wherein the method for operating of (a)~(d), (g)~(j) is identical with traditional mooncake.
In traditional mooncake filling material, owing to contain a large amount of sucrose and grease, the chemical reaction of many complexity has taken place in sucrose, grease and lotus seeds in the damp and hot shovel system of high temperature (f) process, and it is peculiar to produce traditional lotus seed paste mooncake:
1. fine and smooth lubricious mouthfeel characteristic
2. tempting shinny brown pool
3. the peculiar lotus-seed paste fragrance that assails the nostrils of fragrant
But the present invention has used relatively large sweet taste material and dietary fiber, and has reduced the grease use amount.Owing to do not use sucrose, the viscosity that the sucrose batching is had, moistening, satiny matter structure characteristics have been lost, and the chemical reaction of sucrose and lotus seeds many complexity in damp and hot shovel system (f) process, this will make the matter structure and the traditional mooncake of the Sugarless high-fibre low-energy moon cake filling material made that very big difference is arranged.The present invention has solved this problem by above-mentioned prescription design and optimization part, but the filling material of making little rough still is smooth inadequately.Therefore, special 1~2 road super-high-pressure homogenization (e) that increases of the present invention is handled when technological design, requires homogenization pressure to reach 40-70MPa, with further reduction lotus material grain graininess.Like this, just can effectively solve the smooth inadequately problem of Sugarless high-fibre low-energy moon cake filling material.
In baking (1) operation, the baking temperature that the present invention requires moon cake is than low 20~50 ℃ of the baking temperature of corresponding traditional mooncake, the highest can not be above 200 ℃.This is because sweet taste material that the present invention uses such as pure crystal diabetin (103~105 ℃ of fusing points), sorbierite (96~97 ℃), and the fusing point of maltitol (135~140 ℃) etc.s is relatively low, may subside because of fusing is out of shape moon cake in high-temperature baking.Therefore, restricted to the highest baking temperature, time.
In the present invention, for employed packaging material in packing (n) operation strict demand is arranged, require to use the packaging material of good leak tightness, the highest relative humidity of packing shop does not surpass 60%.And in cooling (m) operation, the moon cake after the baking requires to pack immediately after the cooling in the cooling of the workshop of humidity lower (being no more than 60%).This is because sweet taste material used in the present invention and dietary fiber, all be easy to absorb airborne moisture such as batchings such as pure crystal diabetin, pure crystallization FOS, sorbierite, maltitol, glucan, inulin, this is valuable to aspects such as the freshness of keeping moon cake and moisture, but can make the excessive moisture absorption of the moon cake of making and easily moldy metamorphism, shorten the shelf-life.In addition, because the cake skin moisture absorption at first outside, skin filling rate of moisture absorption difference can occur and the skin filling of moon cake is separated.Therefore, the present invention has strict requirement to the humidity in packing (n) and cooling (m) workshop.
The present invention compared with prior art has following advantage:
1, moon cake of the present invention has sugar-free, high fiber, low-energy characteristics, also have and non-ly cause carious tooth, relax bowel, grow physiological functions such as Bifidobacterium, be to healthy and helpful food, it is edible to be fit to very much special populations such as adiposis patient, diabetes patient, cardiovascular patient, children;
2, lubricated, the crisp perfume (or spice) of taste of pure and fresh pure, the delicate mouthfeel of moon cake sweet taste of the present invention;
3, Production of Moon Cake method of the present invention is on the conventional art basis, increases 1-2 road super-high-pressure homogenization and handles, and at the characteristics that moon cake of the present invention is filled a prescription, conditions such as moon cake baking temperature have been made improvement, produces high-quality moon cake.
