Synthesis and characterization of a lactose-based biosurfactant by a novel nanodendritic catalyst and evaluating its efficacy as an emulsifier in a food emulsion system

Abstract

Nonionic lactose fatty acid esters are a class of synthetic biosurfactants with various uses in the food, pharmaceutical, personal care, and cosmetic industries.

Fabrication of a magnetic Mn(ii) cross-linked chitosan-amine/glutaraldehyde nanocomposite for the rapid degradation of dyes and aerobic selective oxidation of ethylbenzene

“…9,35 Additionally, the related peaks to n s (O-Si-O), n s (Si-O-Si), n s (Fe-O-Fe) and n as (Si-O-Fe) can be observed at 462 792, 542 and 1072 cm −1 , respectively. 35,36 The n as (CH 3 ) and s (NH 2 ) vibrations became visible at around 2854 and 1615 cm −1 , respectively, indicating the AEAPS attachment with the surface of the magnetic beads, which veries the formation of a silica shell on the MIO NPs. 35,37 Moreover, the spectrum of IOSC-N-et-NH 2 @CS shows characteristic peaks at 1384 cm −1 , which is ascribed to polymeric chitosan, explicitly conrming the formation of chitosan multi-layers on the core-shell nanocomposite.…”

Antibacterial activity of bioemulsifiers/biosurfactants produced by Levilactobacillus brevisS4 and Lactiplantibacillus plantarumS5 and their utilization to enhance the stability of cold emulsions of milk chocolate drinks

“…This emulsion stabilizing ability of BE/BS could be explained by the fact that the adsorption of BE/BS at the interface between oil and air prevents the coalescence of droplets through electrostatic repulsion (Pinto et al, 2022 ; Rudy, 2011 ). Hence, the Ostwald ripening leading to the coalescence of droplets and an irreversible increase in the droplets' size (Karami et al, 2022 ) is reduced. The ability of BE/BS to control the clustering of globules and thus stabilize aerated systems was also reported in the literature (Lira et al, 2022 ; Santos et al, 2016 ).…”

FORMULASI DAN UJI STABILITAS FISIK EMULGEL EKSTRAK DAUN BINAHONG (Anredera cordifolia) SEBAGAI TABIR SURYA

“…Sementara itu, Tween 80 dan Span 80, yang merupakan jenis emulgator surfaktan, dipilih karena sifatnya yang tidak toksik dan tidak menimbulkan iritasi. Selain itu, penggunaan kombinasi emulgator diketahui dapat menghasilkan pengurangan tegangan antar muka yang lebih besar, menjadikan emulsi yang terbentuk lebih stabil dengan karakteristik hidrofilik dan lipofilik yang seimbang, sebagaimana diungkapkan oleh Karami et al (2022). Dengan demikian, penelitian ini diharapkan dapat memberikan wawasan lebih lanjut mengenai cara optimal dalam mengatur konsentrasi Tween 80 dan Span 80 untuk menghasilkan sediaan emulgel dengan sifat fisik dan stabilitas yang diinginkan.…”
