Abstract
Provided in the present disclosure is a pectin gel and a preparation method thereof, the pectin gel including a pectin and a fat-soluble substance, in which a weight average molar weight of the pectin is in a range of 5.0×10{circumflex over ( )}4 to 6.0×10{circumflex over ( )}5 Da, a polymer dispersion index thereof is in a range of 1 to 6; in the structural domains of the pectin, HG>30 mol % and RG-1≤35 mol %; HG is homogalacturonan and RG-1 is rhamnogalacturonan type I. The pectin gel has high emulsion stability before forming, so the pectin gel after forming has good texture stability, and the amount of water and oil separation is low, and the taste of the pectin gel is good.
Claims20
A pectin gel, comprising a pectin and a fat-soluble substance, wherein a weight average molar weight of the pectin is in a range of 5.0×10{circumflex over ( )}4 to 6.0×10{circumflex over ( )}5 Da and a polymer dispersion index thereof is in a range of 1 to 6;
- in structural domains of the pectin, HG>30 mol % and RG-1≤35 mol %;
- and HG is homogalacturonan and RG-1 is rhamnogalacturonan type I.
A preparation method of a pectin gel, the pectin gel comprising a pectin and a fat-soluble substance, wherein a weight average molar weight of the pectin is in a range of 5.0×10{circumflex over ( )}4 to 6.0×10{circumflex over ( )}5 Da and a polymer dispersion index thereof is in a range of 1 to 6;
- in structural domains of the pectin, HG>30 mol % and RG-1≤35 mol %;
- HG is homogalacturonan and RG-1 is rhamnogalacturonan type I, and the preparation method comprising following steps:
- aqueous phase preparation:
- uniformly mixing the pectin, part of a sugar alcohol, and part of acidity regulator to obtain a gel premix;
- uniformly mixing water, the remaining sugar alcohol, and modified starch, adding the gel premix thereto, and heating to complete dissolution to obtain an aqueous phase;
- oil phase preparation:
- heating and mixing the fat-soluble substance until being uniform to obtain an oil phase;
- emulsification:
- adding the oil phase to the aqueous phase and mixing uniformly, and performing high-speed shear emulsification at 70 to 95° C. to obtain an emulsion;
- blending:
- mixing the remaining acidity regulator and water at 70 to 80° C. until being completely dissolved, and then adding to the emulsion for mixing for 5 to 10 minutes to obtain a material solution;
- and
- forming:
- pouring the material solution on a blister, sealing, and standing still for 40 to 60 hours to be formed stably.
