To make better use of cod head (Gadus macrocephalus), a byproduct of fish processing, the effects of ultrasound pretreatment on the enzymic properties and volatile compounds of cod head enzymic hydrolyzates were investigated. The results demonstrated that ultrasound pretreatment at 150-600 W had a pos. effect cod head enzymic hydrolyzates. The soluble peptides content of the enzymic hydrolyzates reached the highest value of 5.31 ± 0.16 mg/mL at the ultrasound power level of 450 W, and the content of peptide mols. < 3-kDa was up to 93.96%. The type and relative content of volatile compounds, especially aldehydes, alcs., and ketones, also increased with the increase the ultrasound power. The electronic tongue results indicated that ultrasound pretreatment reduced bitterness and astringency. The electronic nose results indicated that the hydrogen- and alkane-containing odor components in the hydrolyzed liquid after ultrasound pretreatment differed significantly from conventional enzymic hydrolyzates. In conclusion, ultrasound pretreatment may be applicable as a suitable technol. to assist enzymic hydrolysis of the cod head, and as such, promote the utilization of fish byproducts. In the experiment, the researchers used many compounds, for example, (1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5COA of Formula: C10H20O).
(1R,2S,5R)-2-Isopropyl-5-methylcyclohexanol (cas: 2216-51-5) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. A multistep synthesis may use Grignard-like reactions to form an alcohol with the desired carbon structure, followed by reactions to convert the hydroxyl group of the alcohol to the desired functionality.COA of Formula: C10H20O
