Abstract

Summary: Apple pomace (APP) is the main by‐product in apple processing industry with abundant functional components. To improve the APP economic value, superfine grinding (SG) was used as an effective processing method. The result showed that SG provided great uniformity and particle size of APP. Also, with SG treatment, the water‐holding capacity and oil‐holding capacity increased from 7.50 to 8.13 g g−1 and from 2.07 to 3.81 g g−1, respectively. Furthermore, SG enhanced the sensory properties by increasing the brightness, yellowness and sweetness and decreasing the sourness and bitterness of APP. For functional properties, SG increased total phenols content, total flavonoids content and the soluble dietary fibre from 5.83 to 8.86 mg g−1, from 4.39 to 6.43 mg g−1 and from 8.50% to 14.51%, respectively. Therefore, SG improved the physicochemical, sensory and functional characteristics of APP powder. The results would provide important information for applying SG techniques in processing APP or other fruit by‐products for future commercial market purposes. [ABSTRACT FROM AUTHOR]

Abstract

Cobalt catalysts promote ring-opening coupling between cyclopropanols and unactivated alkynes to give β-alkenyl ketones or cyclopentenols with exquisite chemoselectivity control., Cobalt–diphosphine catalysts promote ring-opening coupling reactions between cyclopropanols and unactivated internal alkynes, affording either β-alkenyl ketones or multisubstituted cyclopentenol derivatives in good yields with good to excellent regioselectivities. The chemoselectivity between these β-alkenylation and [3 + 2] annulation reactions, which likely share a cobalt homoenolate as a key catalytic intermediate, is exquisitely controlled by the reaction conditions, with the solvent being a major controlling factor. The reactions are proposed to involve ring opening of cobalt cyclopropoxide into homoenolate, migratory insertion of the alkyne into the Co–C bond, and protodemetalation or intramolecular carbonyl addition of the resulting alkenylcobalt species. The feasibility of these reaction steps was supported by DFT calculations.
