In this review, we discuss literature findings, mostly reported in the last decade, on the self-assembly of the four main classes of microbial biosurfactants, <em>i.e.</em>, rhamnolipids, mannosylerythritol lipids, sophorolipids, and surfactin. All of them present composite molecular structures, characterized by different functional groups and ionisable moieties, and a high conformational flexibility. Where possible, we discuss the formation of different aggregate morphologies in terms of biosurfactant molecular structure and variation of environmental parameters. We highlight how the biosurfactant self-assembly is regulated by a complex interplay between various intermolecular interactions, including H-bonds and steric constraints, besides electrostatic and hydrophobic interactions. For this reason, we show that common theoretical approaches to amphiphile self-assembly, such as the critical packing parameter, have limitations in rationalizing and predicting biosurfactant aggregation behaviour.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"70 ","pages":"Article 101792"},"PeriodicalIF":8.9,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029424000104/pdfft?md5=ddb5edf77569fd45576a9e974856fa99&pid=1-s2.0-S1359029424000104-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139893697","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although glycation, also commonly termed as “Maillard reaction”, has been used extensively to modify flavors and stabilize food colloids, its applications for achieving desired oral lubrication performance of food are in its infancy. This review discusses glycation as a biolubrication tool to provide stimulus to future designing of food colloids. Specifically, we examine how glycation drives biolubrication of soft tissues with examples of lubricin and mucin as “brush-like”, nature-engineered, high performance, aqueous lubricants. Recent advances in Maillard conjugation to modify tribology, rheology, adsorption, or surface hydrophobicity of dietary proteins are covered. Lastly, we transfer molecular rules from polymer physics to food colloid science to inspire repurposing glycation of dietary proteins to rationally design the next-generation of lubricious alternative protein-based foods that are often delubricating.</p></div>","PeriodicalId":293,"journal":{"name":"Current Opinion in Colloid & Interface Science","volume":"69 ","pages":"Article 101782"},"PeriodicalIF":8.9,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1359029423001073/pdfft?md5=29f21841f17655ef44ae9b4bd98f5e3a&pid=1-s2.0-S1359029423001073-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has led to intensive research into optimizing their production to increase yields and minimize costs, which is challenging because biotechnological methods for rhamnolipid production result in complex product mixtures and require the introduction of complex separation strategies to ensure the purity of the rhamnolipid obtained.

In addition, the review also discusses some general aspects related to the production and purification methods of rhamnolipids, highlighting the need for further research to fully exploit their potential.

As one of the most important commodity chemicals, their remarkable consumption leads to the necessity of finding sustainable alternatives. Although the use of renewable sources limits the available chemical space for a “Green” production, the great variety of naturally occurring precursors, i.e., fatty acids and sugars, opens a myriad of possibilities to create biosurfactants capable of replacing the fatigued fossil-derived amphiphiles. Here, we visit the concept of isomer-directed assembly applied to sugar-based surfactants, wherein amphiphile assembly and function are fine-tuned through changes in the stereochemical and regiochemical configuration of the molecule. As such, we show how isomerism defines directional interactions and solvation, ultimately dictating the assembly of surfactants.
