The Difference between Fish Hydrolysate and Fish Emulsion

Fish hydrolysate in its simplest form, is grounded up fish carcasses. After the usable portions are removed for human consumption, the remaining fish body, which means the guts, bones, cartilage, scales, meat etc is put in water and ground up. Some fish hydrolysate is grounded more finely then others so more bone material is able to remain suspended. Enzymes may also used to soluble bones scale and meat. If purchasing fish hydrolysate for agricultural application one should look at the label carefully for the concentration of mineral elements in the liquid. Some fish hydrolysates have been made into a dried product, but most of the oil is left behind in this process, which means a great deal of the fungal food component would be lacking.

Fish emulsion is an organic fertilizer. It is a liquid fertilizer made from byproducts of the fish oil and fish meal industry. Fish emulsion is appropriate for many uses in the garden, but is especially useful as a lawn fertilizer in early spring and to feed leafy green vegetable, due to its nitrogen higher content. The ration for Fish emulsion is generally 5-3-3. Fish emulsion is concentrate which you dilute with water and apply to your lawn or garden. It can have strong fishy odor, but deodorized fish emulsion is commonly available as well.

Difference between Fish Hydrolysate and Fish Emulsion

If fish hydrolysate is heated, the oils and certain proteins can be more easily removed to be sold in its purified forms. The complex protein, carbohydrate and fats in the fish material are denatured, which means they are broken down into less complex foods. Over heating can result in destruction of the material as a food to grow beneficial organisms. Once the oils are removed and proteins denatured and simplified by the heating process, this material is called fish emulsion. The hydrolysate process has substantially lower capital and production costs compared to fish emulsion process.
