Glycerol monolaurate (GML) has been explored as a key component in the preparation of bigels, a promising solid fat substitute aimed at reducing cardiovascular disease risk while maintaining desirable food flavors. In this study, GML was used to create oleogels at various concentrations (4-16 wt%) by dissolving it in rapeseed oil, followed by cooling to form solid structures. These oleogels were then combined with gellan gum-based hydrogels to produce bigels at different ratios (1:3, 1:1, and 3:1).
Bigels are a combination of gelled oil and water phases, which can mimic the properties of traditional solid fats but with a reduced fat content. The GML-based oleogels significantly contributed to the texture and stability of the bigels, ensuring a firm structure suitable for use as a fat replacement in food products. The formulation process involved heating and stirring the components, followed by cooling to solidify the mixtures, which were stored at 4 °C until set.
This research highlights the potential of GML as an effective emulsifier and structuring agent for bigels, offering a healthier alternative to solid fats in food products without compromising on flavor. GML-based bigels could thus serve as a functional ingredient in the development of reduced-fat foods that still meet consumer expectations for texture and mouthfeel.

Monolaurin, a monoglyceride derived from glycerol and lauric acid, has emerged as a promising bioamphiphile in the development of supramolecular biosolvents (bioSUPRASs) for the efficient and sustainable extraction of bioactive compounds from agri-food residues. In a recent study, monolaurin-based bioSUPRASs were synthesized via sulfate-induced self-assembly in water-1-propanol mixtures, achieving over 98% incorporation efficiency.
The bioSUPRAS synthesis process involved the precise manipulation of monolaurin, 1-propanol, water, and sodium sulfate concentrations, leading to the spontaneous formation of a two-phase system. The top layer, rich in monolaurin-based bioSUPRAS, exhibited excellent solubilization properties, making it highly effective for the selective extraction of bioactives. As a proof of principle, these bioSUPRASs demonstrated superior performance in extracting bioactive compounds from spent coffee grounds and courgette peels, underscoring their potential in agri-food waste valorization.
Beyond its role in bioSUPRAS formation, monolaurin is widely recognized for its amphiphilic properties, making it an essential ingredient in food, cosmetics, and pharmaceutical formulations. Its large-scale availability and GRAS (Generally Recognized as Safe) status further enhance its appeal as a sustainable solvent alternative. This study highlights monolaurin's versatility, not only as a surfactant and emulsifier but also as a key component in innovative green solvent systems, paving the way for more sustainable extraction methodologies in food and pharmaceutical industries.

Monolaurin (ML) is a well-known antimicrobial agent derived from lauric acid, widely recognized for its efficacy against a broad spectrum of microorganisms, including bacteria and fungi. This study explores the application of ML in the development of antimicrobial cellulose-chitosan (CC) composite films using the sol-gel method. The incorporation of ML into the CC matrix aims to enhance the antimicrobial properties of the films while maintaining their mechanical integrity.
The CC films were prepared by integrating ML at concentrations of 0.5% and 1% into the CC matrix through a sol-gel process. The procedure involved dissolving chitosan in acetic acid to form a homogeneous solution, followed by the addition of ZnO nanoparticles, ammonia, and distilled water to create a transparent sol. Tetraethoxysilane (TEOS) was introduced as a silica precursor to facilitate the formation of inorganic Si-O-Si bonds. The mixture was then subjected to sonication and further stirring to promote hydrolysis and condensation reactions. Glycerol was added as a plasticizer to enhance film flexibility. Finally, ML was incorporated into the mixture at the specified concentrations and stirred until homogenized.
The antimicrobial activity of the CC films was significantly enhanced by the addition of ML. Films containing 0.5% and 1% ML exhibited robust antibacterial properties, outperforming those with lower ML concentrations. This suggests that ML acts as a potent antimicrobial agent within the CC matrix, effectively inhibiting microbial growth. The antimicrobial efficacy of ML is attributed to its ability to disrupt microbial cell membranes, thereby preventing microbial proliferation.
