1. Raw materials are washed and treated before beating. Take ripe seabuckthorn fruit without mildew and wash it with clear water. Beating Use a beater to beat the washed seabuckthorn fruit into coarse pulp, and then use a colloid mill to grind it into fine pulp.

2. Blending and concentration: a certain amount of xylitol and vitamins are added to human serum, and the concentration condition is 45-50℃, 10- 13 kPa, and the content of soluble solids in the concentrated serum is 40%-45%. When the concentration is about to meet the design sugar requirement, adjust the pressure of the concentration tank to normal pressure, then add the thickener (reserve a part of xylitol in advance and mix it evenly) to dissolve the blending agent, sour agent, etc. Use a small amount of warm water, and continue to concentrate to the design sugar requirements.

3. Sterilization and hot filling: quickly heat the concentrated sauce to 95℃, keep it and sterilize it, then pour the sauce into a glass jar scalded with hot water in advance, without affecting the vacuum degree of the jar, and fill it properly when pouring the sauce. The temperature should be above 80℃ when sealing cans, and the unqualified products should be eliminated.

4. As the packaging device of seabuckthorn jam is a glass jar, it should be cooled by stages immediately after sterilization and hot filling, so that the jar can be cooled to room temperature in a short time, and the finished product can be obtained after the moisture outside the jar is dried.
