Pickering emulsion emulsified using novel cellulose nanofibers significantly lowers the lipid release rate and cellular absorption.

A Pickering emulsion is an emulsion system stabilized by solid particles and represents a promising candidate for emulsifying lipids. Cellulose nanofibers (CNFs) have excellent ability to control the lipid release rate. This study aims to find the optimal formulation for a nanocellulose-stabilized Pickering emulsion that is the most effective in reducing the lipid release rate. The Pickering emulsion was prepared by homogenizing pretreated nanocellulose with medium-chain triglycerides using high-speed and ultrasonic homogenizers. The results show that the Pickering emulsion with 0.709% nanocellulose and 30.6% medium-chain fatty acid content yielded an average particle size of approximately 2.5 µm, which is the most stable and effective in reducing the amount of the lipids released. The nanocellulose Pickering emulsion formulation developed in this study forms a significant foundation for future research and applications regarding the use of nanotechnology and Pickering emulsions to maintain the balance between one's health and the desirable flavor of fat.

Current and Potential Applications of Atmospheric Cold Plasma in the Food Industry.

The cost-effectiveness and high efficiency of atmospheric cold plasma (ACP) incentivise researchers to explore its potentials within the food industry. Presently, the destructive nature of this nonthermal technology can be utilised to inactivate foodborne pathogens, enzymatic ripening, food allergens, and pesticides. However, by adjusting its parameters, ACP can also be employed in other novel applications including food modification, drying pre-treatment, nutrient extraction, active packaging, and food waste processing. Relevant studies were conducted to investigate the impacts of ACP and posit that reactive oxygen and nitrogen species (RONS) play the principal roles in achieving the set objectives. In this review article, operations of ACP to achieve desired results are discussed. Moreover, the recent progress of ACP in food processing and safety within the past decade is summarised while current challenges as well as its future outlook are proposed.

Applications of atmospheric cold plasma in agricultural, medical, and bioprocessing industries.

Atmospheric cold plasma (ACP) is a nonthermal technology that is extensively used in several industries. Within the scopes of engineering and biotechnology, some notable applications of ACP include waste management, material modification, medicine, and agriculture. Notwithstanding numerous applications, ACP still encounters a number of challenges such as diverse types of plasma generators and sizes, causing standardization challenges. This review focuses on the uses of ACP in engineering and biotechnology sectors in which the innovation can positively impact the operation process, enhance safety, and reduce cost. Additionally, its limitations are examined. Since ACP is still in its nascent stage, the review will also propose potential research opportunities that can help scientists gain more insights on the technology. KEY POINTS: • ACP technology has been used in agriculture, medical, and bioprocessing industries. • Chemical study on the reactive species is crucial to produce function-specific ACP. • Different ACP devices and conditions still pose standardization problems.

Producing high quality mung bean sprout using atmospheric cold plasma treatment: better physical appearance and higher γ-aminobutyric acid (GABA) content.

BACKGROUND: Germination of mung beans increases the content of dietary fiber, vitamin C, antioxidants, and γ-aminobutyric acid (GABA). Atmospheric cold plasma is a recently developed technology that can rapidly modify the surface properties of an object. In this work, atmospheric cold plasma was utilized to promote higher moisture absorption of mung bean seeds and, thus, enhance the germination ratio and GABA level. The selected healthy seeds that were exposed to plasma generated at different ionizing powers. RESULT: According to the experimental results, atmospheric cold plasma treatments on mung bean seeds could induce significantly more water absorption and lead to a higher rate of germination. The physical appearance of the sprout developed after plasma treatment was noticeably modified to a more desirable form, which has a short radicle and longer hypocotyls with a larger diameter. The content of the bioactive component GABA in plasma-treated beans was approximately three times higher than the untreated group due to the response of seed to the environmental stress created by the plasma treatment. CONCLUSION: The result from this work will serve as a good reference for future investigation that is searching for a solution to enhance bioactive compound production in natural products. © 2021 Society of Chemical Industry.
