Advantages and Disadvantages to Propionic Fermentation

Organic acids have been the most consistent high-moisture hay preservative for high-quality alfalfa hay. Propionic acid (propionate), the most common organic acid used and most effective when used at the correct rates, acts as a fungicide inhibiting growth of aerobic microorganisms that are responsible for the heating and molding of high-moisture hay. Some commercial products use a small amount of acetic acid or add additional compounds like inorganic acids, formaldehyde, or flavoring ingredients.
The ADVANTAGES of using Propionic Acid as a high-moisture preservative include reducing mold, reducing drying time in the field, reducing potential rain damage, reducing leaf loss from harvesting at a greater moisture content, and providing more baling flexibility. Baling can be initiated earlier in the day and can continue later into the evening allowing greater acreage to be harvested.
And Propionic Acid also using in herbicide, spice and medicinal.
Ex:
In the fragrance industry, propionic acid can be produced with spices isoamyl propionate, linalyl acetate, propionate, geranyl acetate, ethyl propionate, benzyl propionate, etc., and then used in food, cosmetics, soaps, spices. In the plastics industry, with propionic acid, and cellulose acetate can produce a cellulose acetate propionate (CAP), which can be prepared with a biodegradable plastic, used for films, toothbrush handles, brush handle and the eyeglass frame. CAP can also be used in the field of ink.
In addition, the system can take with acid organic chemical raw materials and intermediate propionic anhydride, α- chlorine acid, propionic acid and 2,2-dichloro-α- bromine acid. Wherein, propionic anhydride perfume esterifying agent, can be used as the sulfurization reaction and the nitration reaction of a dehydrating agent, can also be used alkyd resins, dyes and pharmaceutical production.
In the pharmaceutical industry, mainly propionic acid derivative of vitamin B6, naproxen, cerebral veins Ning. Our annual production capacity has reached vitamin B6 2800 tons, every year a certain number of exports in the international market occupies a share. The pharmaceutical industry is expected to demand for propionic acid will increase.
Propionic acid are weaker inhibit fungal growth in vitro and in vivo. Treatment of fungal diseases of the skin can be used, often formulated with zinc undecylenate compound preparation for external use, ointment: 3% (acid) or 5% to 10% sodium propionate.
The DISADVANTAGES of using Propionic Acid:
The fatalness to humans - Inhalation of this product has a strong irritant to the respiratory tract, pulmonary edema can occur, steam strong eye irritation, liquid can cause serious eye damage. Skin contact can cause burns, large oral nausea, vomiting and abdominal pain, autism incentives.
The perniciousness of environment - It can contaminate the water.
Fire and explosion hazards - This product is flammable, corrosive, strong irritant, can cause the body burns.
