“…Türkŏglu et al fabricated a wheat germ oil (WGO)-loaded multilayer hydrogel dressing by cross-linking sodium alginate (SA) with poly(ethylene glycol) diglycidyl ether (PEGDGE) on textile nonwovens [ 74 ]. This multilayer hydrogel showed rapid and positive swelling properties with an interconnected network of pores, and the resultant product was able to support the treatment of burns and wounds with medium to high exudate, and thus may be a promising alternative to conventional products in the wound healing field.…”

Hydrogels have been widely used in many fields including biomedicine and water treatment. Significant achievements have been made in these fields due to the extraordinary properties of hydrogels, such as facile processability and tissue similarity. However, based on the in-depth study of the microstructures of hydrogels, as a result of the enhancement of biomedical requirements in drug delivery, cell encapsulation, cartilage regeneration, and other aspects, it is challenge for conventional homogeneous hydrogels to simultaneously meet different needs. Fortunately, heterogeneous multilayer hydrogels have emerged and become an important branch of hydrogels research. In this review, their main preparation processes and mechanisms as well as their composites from different resources and methods, are introduced. Moreover, the more recent achievements and potential applications are also highlighted, and their future development prospects are clarified and briefly discussed.

“…WGO has a higher tocopherol content than other vegetable oils, up to about 2,500 mg/kg, with α-tocopherol is predominant accounting for 60% of the total content (Ghafoor et al 2017). In particular, it is worth noting that vitamin E has up to 500 ppm (Türkoğlu et al 2021). WGO contains a high concentration of unsaturated fatty acids, speci cally linoleic and linolenic acids, which are important compounds in human metabolism but cannot be produced by organisms' method.…”

Wheat germ oil (WGO) in water emulsion is increasingly being used in a variety of fields due to its outstanding nutritional and health benefits. To enhance WGO composability, emulsification should be performed to allow them to dissolve more easily in the food matrix or active packaging. Membrane emulsification is a promising advanced homogenization technology that has recently been developed. This research focused on application of membrane emulsification for homogenization of WGO-in-water emulsion polyether sulfone (PESU) membrane with 0.45 µm of pore size, operating pressure from 5 to 9 bar, with WGO fraction in range 10 – 20% w/w and lecithin ratio in range 0 – 0.2% w/v were evaluated on the mean of particle diameter, distribution of particles diameter, stability of emulsion, and permeate flux. Higher operating pressure led to smaller mean particle diameters, higher homogenization efficiency and permeate flux. However, increasing the WGO fraction showed the opposite trend. Notably, increasing lecithin ratio from 0 to 0.2%, the mean particle diameter increased from 3.36 to 7.72 µm, homogenization efficiency decreased from 98.54 to 97.68%, and permeate flux decreased from 105.95 to 77.45 L.h-1.m-2. The results showed the advantage of using PESU membrane in WGO-in-water homogenization, that produce emulsions with small particle size (50% of particle volume was less than 5µm), high emulsion stability (greater than 95%) and lower emulsifier usage. Results imply premix membrane emulsification is potential to apply homogenization WGO-in-water emulsion.

“…It is up to about 2500 mg kg −1 , with α‐tocopherol content accounting for up to 60% of total tocopherol content (Ghafoor et al ., 2017). The most well‐known α‐tocopherol in WGO is vitamin E, which can also be as high as 500 ppm (Türkoğlu et al ., 2021). As a result, WGO has the ability to prevent lipid peroxidation, which improves cell protection against free radicals as a cell membrane stabiliser (Zhu et al ., 2011).…”

“…Hence, the presence of various nutrients and potential bioactive in WGO makes it a strong candidate for the development of natural medicines and nutraceuticals. Nowadays, WGO is widely used in food production, formulation products, pharmaceuticals, cosmetics and even agriculture (Choi & Kang, 2009; Boukid et al ., 2018; Türkoğlu et al ., 2021; Wang et al ., 2021). However, the high content of antioxidant, polyunsaturated fatty acids in WGO makes it highly prone to oxidation under high temperature, and long processing time conditions (Sonntag, 1979; Megahed, 2011).…”

Wheat germ oil (WGO) is well-known as a good source of vegetable oil due to its nutrients and health benefits. Emulsification is a process that improves the incorporation of oil into food. High-pressure homogenisation (HPH) is a nonthermal and soft technique with enormous potential in oil-in-water emulsification. This paper focussed on the application of HPH for emulsification of WGO-in-water system. Influences of homogenisation pressure (100-300 bar), oil fraction (10-20% v/v) and lecithin adding (0-0.2% w/v of content) on the homogenisation were evaluated based on distribution of particles diameter and homogenisation efficiency. The increase in operating pressure and lecithin ratio decreased the particle size and increased the emulsion stability, and vice versa for oil fraction. The findings imply that the investigated factors significantly influenced particle size and emulsion system stability. The regression model between mean particle diameter and technical conditions of emulsion was established. With HPH treatment conditions of 300 bar operating pressure, 10% (v/v) oil fraction and 0.2% (w/v) lecithin created an emulsion system with a mean particle size of 3.32 µm, more than 50% of the volume of particles smaller than 1.5 µm of diameter and the homogenisation efficiency of 98.61%. HPH exhibits high efficiency and potential in WGO-in-water emulsification application.
