Summary of the invention
It is single that the present invention will solve existing lotus seeds product form, lotus seeds boil post-drying leave standstill, water activity is difficult to keep, affect mouthfeel, and the improvement mode of existing lotus seeds local flavor is mainly interpolation dressing, because dressing is thinner with respect to the radius of lotus seeds, therefore this mode is improved limited problem to the taste of lotus seeds, and note core lotus seeds of a kind of outsourcing chocolate and preparation method thereof are provided.
Note core lotus seeds for outsourcing chocolate, the note core lotus seeds that it is characterized in that a kind of outsourcing chocolate are to be made up of note core colloid, the drying lotus seeds of coring and chocolate-coated; Described note core colloid is prepared from by syrup, rehydration gelatin solution and Herba Menthae powder; Described rehydration gelatin solution is prepared from by rehydration gelatin and water; Described rehydration gelatin and the mass ratio of water are 1:(2~10); In described rehydration gelatin solution, rehydration gelatin and syrup mass ratio are 1:(5~7); Described Herba Menthae powder and the mass ratio of syrup are 1:(50~70).
The preparation method of the note core lotus seeds of a kind of outsourcing chocolate of the present invention carries out according to the following steps:
One, the drying lotus seeds preparation of coring: by fresh lotus seed core removal, classification, obtain coring lotus seeds, by after coring lotus seeds rinsing sterilizing, be placed in temperature and be the water poach 20min~40min of 52 DEG C~58 DEG C, then the coring lotus seeds after poach are placed in to temperature and are dry 30min~60min under the condition of 47 DEG C~52 DEG C, obtain the drying lotus seeds of coring;
Two, note core colloid preparation: 1., be at 125 DEG C~135 DEG C in temperature, white granulated sugar is mixed to molten sugar with maltose, standing uniform and stable, obtain syrup; Described white granulated sugar and the mass ratio of maltose are 1:(0.3~3); 2., rehydration gelatin is mixed with water under room temperature and leaves standstill until rehydration gelatin complete swelling, be then water-bath 50min~80min in the water of 33 DEG C~37 DEG C in temperature, leave standstill uniform and stablely, obtain rehydration gelatin solution; Described rehydration gelatin and the mass ratio of water are 1:(2~10); The syrup mass ratio that in described rehydration gelatin solution, 1. rehydration gelatin and step 2 obtain is 1:(5~7); 3., be at 75 DEG C~85 DEG C in temperature, by syrup, rehydration gelatin solution and the miscible mediation of Herba Menthae powder, until with sugariness instrumentation amount solid content be 70%~90%, and temperature be at 77 DEG C~83 DEG C insulation preserve, obtain noting core colloid; Described Herba Menthae powder and the mass ratio of syrup are 1:(50~70);
Three, chocolate-coated preparation: being at 57 DEG C~63 DEG C in temperature, by miscible to substitute of cocoa fat, cocoa power, white granulated sugar and glycerin monostearate mediation, and is that at 57 DEG C~63 DEG C, insulation is preserved in temperature, obtains chocolate-coated; Described cocoa power and the mass ratio of substitute of cocoa fat are 1:(7~9); In described cocoa power and step 3, the mass ratio of white granulated sugar is 1:(0.5~2); Described cocoa power and the mass ratio of glycerin monostearate are 1:(0.02~0.08);
Four, note core, dressing and dry: be at 77 DEG C~83 DEG C in note core temperature, to note core colloid note core in the drying lotus seeds of coring, obtain noting the drying lotus seeds of core, then be at 57 DEG C~63 DEG C in dressing temperature, by chocolate-coated dressing to note core drying lotus seeds, and be dry 20min~40min at 37 DEG C~42 DEG C in temperature, obtain the note core lotus seeds of outsourcing chocolate.
The invention has the beneficial effects as follows: the present invention is on current existing basis of lotus seeds being carried out to packaging technique, solve the problem of controlling lotus seed products water activity, extend to greatest extent the tasting time of product, and, this kind mode thinner with respect to the radius of lotus seeds for dressing improved limited problem to the taste of lotus seeds, add lotus seeds have been noted to this mode of core, make the taste of product abundanter, be easy to be accepted by more people.Note core lotus seeds and the manufacture craft thereof of the outsourcing chocolate of a kind of delicate mouthfeel, unique flavor are provided thus.The edible way of the note core lotus seeds of outsourcing chocolate is instant.Lotus nut removal lotus seeds to bitter taste changes the note core colloid with peppermint taste into, makes lotus seeds taste better abundant in removing lotus seeds bitter taste.Yellow that product inner core is translucent, be rich in gloss and elasticity, there is the distinctive fresh scent of strong peppermint, have good chewiness.Pass through sterilization treatment, under normal temperature air-proof condition, detection by microbiological indicator (comprising that flora sum≤100cfu/mL, coliform count≤1MPN/mL, pathogenic bacteria must not detect) can keep never degenerating in 2~March, under 1~6 DEG C of condition, can keep never degenerate for 5~June.Described note core colloid and syrup, obtain the best proportioning of raw material by single factor, orthogonal test, possess optimum taste.
The present invention is used for note core lotus seeds of a kind of outsourcing chocolate and preparation method thereof.
