“…Thus, the addition of LA to the EC oleogel increase the recovery ability leading to improved thixotropic performance. Partial recovery was also previously detected for 8 wt% EC 10 cP (DOW chemicals) . Improved thixotropic properties were also demonstrated while adding palm stearin to hydroxy propyl methyl cellulose (HPMC) 4000 cps based oleogels .…”

The use of oleogels in a wide range of applications requires a broad diversity of gel properties tailored for each purpose. The current research explores the combination of ethyl-cellulose (EC) with lauric acid (LA), at different ratios with an emphasis to explore each component contribution and function in the gel structure and properties. The results suggest that oleogel physical properties strongly depend on the EC concentration. A transition from antagonistic to synergistic behavior between EC and LA with respect to the mechanical properties is observed above 4 wt% polymer. This behavior is seen in all LA concentrations, suggesting that the main effect arises from the EC while the LA acts as a stabilizer. In addition, LA reduces EC gelation temperature from approximately 140°C to 79-101°C, depending on the EC concentration, suggesting a 'plasticizing' effect. The recovery ability of EC oleogel after large amplitude deformation is improved from 16% to 34% due to the LA crystalline nature. LA crystal structure is not affected by EC concentration; however its crystallization temperature shifts to a lower temperature. Practical Applications: These results provide a broad overview of the composition-function relation obtained while combining EC with LA.

“…In the last few years, the research on structuring of triglyceride solvents (vegetable oils) has received considerable interest from both academic as well as industrial researchers. The possibility of transforming liquid oils into so, viscoelastic gels (organogels) opens up a number of opportunities for applications such as the development of trans and saturated fat-free food products, [1][2][3][4] transdermal drug delivery systems, 5 bio-based lubricants 6 and analysis and purication-related systems. 7 Since the applications of organogels range from non-bio to bio-related elds, the choice of structurants determines the suitability of using organogels in a range of unrelated elds.…”

“…Organogels can replace PHVOs because of their solid structure at room temperature, and their application is increasing in the food, cosmetics, and pharmaceutical industries (Co & Marangoni, ; Jang, Bae, Hwang, Lee, & Lee, ; Jibry, Sarwar, & Murdan, ; Patel & Dewettinck, ; Stortz & Marangoni, ). Bakery products are one of the main applications of organogels because of the need to replace PHVOs.…”

To enhance the oxidative stability of organogels made from canola oil, 40 ppm sesamol was added to beeswaxbased organogels stored under ultraviolet (UV) light irradiation and 60 or 100°C thermal oxidation conditions. To study the practical application of organogels as animal fat substitutes, beef tallow was mixed with organogels and their oxidative stability was determined under oxidative stress conditions. Without sesamol addition, the organogels and beef tallow with organogel oxidized rapidly under UV irradiation and thermal oxidation. The addition of 40-ppm sesamol decreased the consumption of headspace oxygen and the formation of primary and secondary oxidation products significantly (P < 0.05) compared with those in samples without the addition of sesamol, irrespective of oxidative stress. Sesamol improved the oxidative stability of organogels and beef tallow with organogel, which could be used in the meat industry.Practical Application: Organogels may replace trans-fat or highly saturated lipids in food products. The high degree of unsaturation and processing temperature mean that antioxidants are needed to extend the shelf life of organogels or organogel-containing products. The addition of sesamol significantly enhanced the oxidative stability of organogels and of beef tallow-containing organogels under UV irradiation and thermal oxidation conditions. Therefore, sesamolsupplemented organogels could replace saturated fats in beef tallow and prolong the shelf-life of meat products.

The replacement for petrolatum: thixotropic ethylcellulose oleogels in triglyceride oils

Abstract: Ethylcellulose oleogels were engineered to be thixotropic such that they recover their viscosity after shearing which allows them to be more easily manufactured into food and cosmetic products.
