Applications Of Freeze Drying
Freeze-drying technology is more and more popular with people due to its incomparable advantages. It has been widely used in various fields such as medicine, biological products, food, and active substances. Its application scale is still expanding rapidly. Here Hawach listed the present applications of freeze drying.
(1) Application of freeze-drying in biological products
a. Live bacteria vaccine. For example, BCG vaccine, meningococcal vaccine, tuberculosis vaccine, oral live dysentery vaccine, salmonella, streptococcus, etc.
b. Fire-toxin vaccine. Such as the measles vaccine, flu vaccine, rabies vaccine, chicken plague vaccine, etc.
c. Other biological products and biochemical drugs. Hepatitis B surface antigen diagnosis snowball, human leukocyte interferon, coenzyme A (CoA), adenosine triphosphate (ATP), urokinase, etc.
(2) Application of freeze-drying in western medicine production
Most of the western medicines are injections, antibiotic drugs, circulatory drugs, central nervous drugs, vitamins, and oncology drugs. For example, ampicillin, erythromycin ethylsuccinate tablets, and so on.
(3) Application of freeze-drying in the production of Chinese medicine
In recent years, the freeze-drying method has been used to process Chinese patent medicines. The prepared Chinese patent medicines are dipped, extracted, filtered, concentrated, and freeze-dried, and then made into powders, tablets, or injections.
(4) Application of freeze-drying in medical fields
The applications of lyophilization also include its use in medical fields. A lyophilization machine can be used to preserve various organs such as blood, arteries, bones, skin, cornea, and nerve tissue for a long time. The cells are not destroyed when lyophilized, and the organism can be revived after rehydration. For example, lyophilized bones can be stored at room temperature or in the refrigerator for up to 2 years.
(5) Application of freeze-drying in food
The applications of lyophilization in foods usually refers to its use in food processing, which includes the processing of the following materials:
a. Cooking ingredients: meat, eggs, fish, vegetables, etc.
b. Raw materials for the food industry: milk powder, egg powder, vegetable protein powder, tea, dried fruits, meat powder, soy powder, etc.
c. Beverages: coffee, fruit treasure, etc.
d. Supplements: pollen, bee powder, turtle powder, etc.
(6) Application of freeze-drying in other fields
a. Microorganisms and algae: such as long-term preservation of various bacteria, yeasts, enzymes, protozoa, microalgae, etc.
b. Biological specimens and biological tissues. For example, the production of various animal and plant specimens, dry preservation of skin, bones, aorta, heart valves, and other marginal tissues used for animal xenograft or allogeneic transplantation.
c. Advanced nutritional products and Chinese herbal medicine: such as royal jelly, honey, pollen, Chinese herbal medicine preparations, etc.
d. Preparation of ultra-fine powder: r such as Al2O3, ZrO2, TiO2, Ba2Cu3O7-8, Ba2Ti9O20.
g. The catalyst in the chemical industry, which can increase the catalytic efficiency by 5-20 times after freeze-drying; freeze-dry plant leaves and soil to study the influence of soil, fertilizer, and climate on plant growth; wet wooden cultural relics, drowned book manuscripts, etc.
