Abstract:
To investigate the impact of safflower seed oil on the structural and digestive properties of complexes formed by fatty acids of varying chain lengths with maize starch, the starch-fatty acid ternary complexes were prepared by a hydrothermal method. The results indicated that safflower seed oil inhibited the complexation of relatively short-chain fatty acids (C10:0, C12:0, and C16:0) with starch, and promoted the complexation of long-chain fatty acids (C18:0). Intriguingly, safflower seed oil showed no significant impact on the formation of linoleic acid (C18:2) complexes, suggesting selective interactions within the starch-fatty acid complexes. In addition, the addition of safflower seed oil did not affect the thermal stability of the complexes, but significantly improved the anti-digestibility properties of the starch-complexes in each group, with the RS content reaching 59.08 % in the C16:0 group. In conclusion, this study provides insights for the development of high-quality resist starch-lipid ternary complexes.

Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
Esters to Carboxylic Acids: Saponification
The reaction requires a base in stoichiometric amounts, which participates in the reaction and is not regenerated later. So, the base acts as a...
Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
Amides to Carboxylic Acids: Hydrolysis
Acid-catalyzed hydrolysis:
Hydrolysis of amides under acidic conditions yields carboxylic acids. Since the reaction occurs slowly, hydrolysis requires the conditions of heat.
The mechanism begins with the protonation of the carbonyl oxygen by the acid catalyst. The protonation makes the amide carbonyl carbon more...
