Sunflower Oil Meals:

Can be used for making fish feed of high protein or fast food materials. In Japan, people would crush and puff sunflower oil cake, plus 18% ~ 25% percent of sunflower oil residue to ordinary feed to make high protein fish feed. When making fast food materials, crush sunflower oil meal, then add wheat flour, corn flour, sticky polysaccharide and puff. Sunflower oil cake can also be used for brewing soysauce, and mixed with wheat bran, through a series of steps to get the soysauce of high quality which includes adding water, cooking, making aspergillus oryzae, adding salt water to ferment, drenching the oil etc. And the protein utilization rate can be more than 73%.

Filter, add nucleotide, flavor substances of chicken oil, glucose, cysteine, heat and dry in the condition of 110℃ to get powder freshness agents which is fresher than ordinary monosodium glutamate.

Sesame Oil  Meals:

Can be extracted to decompose the antihypertensive peptides. In Japan, the alkali would be added to the sesame residue to extract the oil. Then acid is added to adjust the the isoelectric point to decompose the protein, and get the antihypertensive peptides in the end.

Coconut Oil Meals:

After coconut oil pressing, there would be residue which needs recycling. Coconut meals can be carbonized under high temperature, then gasified and cooled to recycle the coconut oil which is used in plastics, rubber and other fields.
