Examples
Embodiment 1
[0037] Preparation of maltodextrin with DE value of 5-6.
[0038] Sizing: 500Kg corn starch, concentration 30% (W / W), pH 6.5, enzyme 0.3L / t starch.
[0039] Injection: The height of the needle valve is 1 circle, the material pressure is 0.4Mpa, the steam pressure is 0.13Mpa, the back pressure is 0.03Mpa, and the injection temperature is 105-107°C.
[0040] Insulation liquefaction: temperature 90°C, time 1.5 hours.
[0041] Enzyme inactivation: The height of the needle valve is 1.5 circles, the material pressure is 0.4Mpa, the steam pressure is 0.3Mpa, the back pressure is 0.2Mpa, and the injection temperature is 130°C.
[0042] The product is obtained by decolorization, plate and frame filtration, concentration and spray drying.
Embodiment 2
[0044] Preparation of maltodextrin with DE value of 2-3.
[0045] Blending: 55Kg indica rice flour, concentration 25% (W / W), pH 6.1, enzyme 0.3L / t starch.
[0046] Injection: The injection temperature is 105-107°C.
[0047] Insulation liquefaction: the temperature is 95°C, and the time is 15 minutes.
[0048] Enzyme inactivation: spraying temperature 130°C
[0049] It is obtained by concentration and spray drying.
Embodiment 3
[0051] Application of maltodextrin with DE value of 5-6.
[0052] Chrysanthemum extract %
[0053] Maltodextrin with a DE value of 5-6 has the characteristics of low sweetness, good solubility and stability, and can be used in clear solid chrysanthemum essence beverages. When maltodextrin replaces about 66% of powdered sugar, the sweetness of the product is acceptable. The addition of maltodextrin can reduce the amount of chrysanthemum extract and reduce product cost.
