Embodiment 1
[0025] Embodiment 1, a kind of defoamer for food
[0026] The food defoamer described in Example 1 of the present invention consists of the following components in mass percent: polysiloxane 18%, polyether modified silicone oil 10%, hydrophobic silica 8%, emulsifier 4%, thickener 5% agent, 55% water, the polysiloxane is composed of simethicone oil I with a viscosity of 0.1pa·s, simethicone II with a viscosity of 50pa·s and hydroxyl silicone oil in a weight ratio of 1:0.6:0.5 Ratio composition; Wherein said emulsifier Tween-20 and glyceryl monostearate are formed by the weight ratio of 1:0.5, and described thickener is made up of xanthan gum and chitosan oligosaccharide by the weight ratio of 1:0.4.
[0027] Preparation:
[0028] A) Add polysiloxane and hydrophobic silica into the reaction kettle, stir for 8 minutes, set the stirring speed at 50 rpm, and react at 200°C for 3 hours to obtain a suspension;
[0029] B) Cool the suspension to 90°C, add polyether modified silicone...

[0034] Preparation:
[0035] A) Add polysiloxane and hydrophobic silica into the reaction kettle, stir for 8 minutes, set the stirring speed at 40 rpm, and react at 180°C for 4 hours to obtain a suspension;
[0036] B) Cool the suspension to 90°C, add polyether mod...
Embodiment 3
[0039] Embodiment 3, a kind of defoamer for food
[0040] The food defoamer described in Example 3 of the present invention consists of the following components in mass percent: polysiloxane 22%, polyether modified silicone oil 6%, hydrophobic white carbon black 12%, emulsifier 5%, thickener 6% of agent and 49% of water, the polysiloxane is composed of simethicone oil I with a viscosity of 1pa·s, simethicone II with a viscosity of 55pa·s and hydroxyl silicone oil in a weight ratio of 1:0.8:0.3 Composition; Wherein said emulsifier Tween-20 and glyceryl monostearate are formed by the weight ratio of 1:1, and described thickener is made up of xanthan gum and chitosan oligosaccharide by the weight ratio of 1:0.5.
[0041] The preparation method refers to Example 2.
