Piper nigrum is used both as medicine and food. It is not only a Chinese herbal medicine, but also a kind of edible spice and condiment. Piper nigrum extract is made with edible ethanol and works as natural preservatives, which can not only replace chemical synthetic preservatives that have a certain impact on human health, but also are harmless to humans and have a certain medical and health care effect. At the same time, it also gives food a unique fragrance, which caters to pursuit after natural foods, green foods, and healthy foods.

1. Water extraction
Most alkaloids is with low solubility in water. The acidic water extraction prepared with HCl can convert the less soluble piperine in pepper into the more soluble piperine salt and extract it. The operation method is as follows: crush the pepper grains and place them in a container, add the specified amount of acid water, decoct twice, 0.5h each time, combine the filtrate and place in the refrigerator,
keep cold for 12h, take out suction filtration, and place the filtrate in The extract is concentrated in a constant temperature water bath, and then placed in a vacuum dryer to vacuum dry to obtain piperine.
raw materials → crushing (40 mesh) → ethanol extraction or Soxhlet reflux extraction → filtration → rotary evaporator concentration → stock solution. Through orthogonal experiments and verification experiments, the best extraction process parameters for extracting antiseptic substances in pepper with edible ethanol are: solid-liquid ratio 1:25, extraction temperature 70℃, extraction time 20h.
Pepper extract is extracted with edible ethanol and made into natural preservatives, which can not only replace chemical synthetic preservatives that have a certain impact on human health, but also harmless to the human body and have a certain medical and health care effect. At the same time, it also gives food a unique fragrance, which can satisfy People’s needs for natural foods, green foods, and healthy foods .
