Embodiment 1

[0015] (1) Fully dissolve the pullulan in pure water at a concentration (weight) ratio of 1%, and set aside.

[0016] (2) Weighing (weight %): weigh various ingredients according to the chocolate formula: white granulated sugar powdered sugar (120-150 mesh) 40%, whole milk powder 15%, skimmed milk powder 10%, cocoa butter 25%, cocoa 10% powder, 0.5% lecithin; appropriate amount (trace amount) of spices.

[0017] (3) Fine grinding: Melt cocoa butter at ≤60°C and finely grind it with other ingredients (except lecithin) at 40-50°C for 16-22 hours, requiring fineness ≤20 μm and moisture <1%.

[0018] (4) Refining: Refining the ground material together with lecithin at 48-65°C for 2448 hours until the chocolate liquor reaches a certain fluid state and meets its control index.

[0019] (5) Temperature adjustment and heat preservation: firstly, the chocolate slurry is lowered from 40°C to 29°C, so that the cocoa butter begins to crystallize; then it is cooled from 29°C to 27°C to fo...

Embodiment 2

[0023] (1) Fully dissolve the pullulan in pure water at a concentration (weight) ratio of 3%, and set aside.

[0024] (2) Weighing (weight%): Weigh various ingredients according to the formula: white granulated sugar (120-150 mesh) 44%, whole milk powder 15%, skimmed milk powder 10.5%, cocoa butter 20%, cocoa powder 10%, 0.5% lecithin; appropriate amount (trace amount) of spices.

[0025] (3) Fine grinding: Melt cocoa butter at ≤60°C and finely grind it with other ingredients (except lecithin) at 40-50°C for 16-22 hours, requiring fineness ≤20 μm and moisture <1%.

[0026] (4) Refining: Refining the ground material together with lecithin at 48-65°C for 24-48 hours until the chocolate liquor reaches a certain fluid state and meets its control index.

[0027] (5) Temperature adjustment and heat preservation: firstly, the chocolate slurry is lowered from 40°C to 29°C, so that the cocoa butter begins to crystallize; then it is cooled from 29°C to 27°C to form the crystallization ...

Abstract

The invention relates to pullulan-containing chocolate and a process for producing products thereof. The process comprises the following steps of: when the pullulan is used as a film coating agent: fully dissolving pullulan in pure water to prepare aqueous solution at a weight concentration of 0.5 to 5 percent for later use, weighing up all raw materials according to the formula of the chocolate, and evenly coating the prepared aqueous solution of pullulan on the surface of a mould during injection moulding; and when the pullulan is used as an emulsifier: fully dissolving pullulan in pure water to prepare aqueous solution at a weight concentration of 0.5 to 1 percent for later use, melting cocoa butter in the formula at a temperature of less than or equal to 60 DEG C, mixing the melted cocoa butter with other raw materials except lecithin and pullulan, fine-grinding the mixture at a temperature of between 40 and 50 DEG C for 16 to 22 hours until the degree of fineness is less than or equal to 20mum and the water content is less than 1 percent, adding lecithin and aqueous solution of pullulan respectively, refining the mixed solution at a temperature of between 48 and 65 DEG C for 24 to 48 hours until the chocolate pulp is in a certain fluid state, performing the working procedures of temperature regulation, thermal preservation, injection moulding, jumping vibration, cooling, demoulding, picking, packaging and storing. With the pullulan, the chocolate offers a fine taste, is insusceptible to melting and frosting and can be stored for a long time.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a production process of pullulan-containing chocolate and its products. Background technique [0002] Pullulan, also known as pullulan, pullulan. It is a kind of extracellular pure natural polymer polysaccharide produced by microbial fermentation with starch or sugar as raw material. Its chemical composition is mainly polymaltotriose linked by α-1,6 glucosidic bonds, and it is very soluble in water. , safe and non-toxic, colorless and tasteless. Pullulan polysaccharide has excellent film-forming properties, water retention and adhesiveness, is edible and low in calories, and has a wide range of uses in cosmetics, medicine, food and other industries. In 2006, it was listed in the food additive catalog by the Ministry of Health; However, the application in the preparation of chocolate is still blank, and there is no relevant report on the application of pullulan in chocolate proces...
