Application of oil residue

The protein on the sesame meal could 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.

We also use sesame dregs with sesame special fragrance and delicious taste into sauce food. The method is to mix sesame oil residue with cereals (more than 10%). Grain may be rice, and the ratio of rice and sesame residue is 1:0.5, it may also be wheat, and the ratio is 1:0.24. Add water and aspergillus to the mixed raw materials for brewing.

Sunflower meal 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%.

Extract ferulic acid from oil meal. And water, sodium hudroxide and isopropyl alcohol would be added to the meal. Then heat, hydrolyze and cool to remove the N-hexane solutes. And you would get the ferulic acid precipitation in the acid condition. The final step is to refine. Ferulic acid has strong antioxidant effect which can prevent oil and juice oxidation.
You also can use peanut meal to produce flavor enhancer. After crushing peanut meal, soak it in hydrochloric acid, and then add alkali  to neutralization.
