Despite centuries of developing strategies to prevent food-associated illnesses, food safety remains a significant concern, even with multiple technological advancements. Consumers increasingly seek less processed and naturally preserved food options. One promising approach is food biopreservation, which uses natural antimicrobials found in food with a long history of safe consumption and can help reduce the reliance on chemically synthesized food preservatives. The hurdle technology method that combines multiple antimicrobial strategies is often used to improve the effectiveness of food biopreservation. This review attempts to provide a research summary on the utilization of lactic acid bacteria, bacteriocins, endolysins, bacteriophages, and biopolymers helps in the improvement of the shelf-life of food and lower the risk of food-borne pathogens throughout the food supply chain. This review also aims to evaluate current technologies that successfully employ the aforementioned preservatives to address obstacles in food biopreservation.

From Laboratory Microgrid to Real Markets
Liang Tao,Christine Schwaegerl,Sankar Narayanan,Jian Hui Zhang 전력전자학회 2011 ICPE(ISPE)논문집 Vol.2011 No.5
This paper aims to identify and briefly address major gaps between nowadays technical (laboratory/pilot) Microgrid solutions and real-life (quasi-)commercial Microgrid market demands under a global setting. Firstly, both technical and commercial aspects of Microgrid story are illustrated in parallel; both sides’ inherent motivations, scopes, business models etc. are compared. Then the paper deeper identifies and discusses existing gaps for application under three different categories: Major (internal) technical gaps: · Grid-connected and off-grid dual mode operation support · Meeting Microgrid network constraints / requirements · Protection solution for new / upgraded Microgrids Major (external) regulatory gaps: · Islanding vs. anti-island vs. low voltage ride through requirements · Microgrid controllability definition at point of common coupling Major market gaps: · Acknowledgement of local consumption; · Extra incentives and differentiation from DG market Consequently, general gap-narrowing principles and techniques are recommended for the above listed issues. Then the corresponding responsibilities and benefits of main stakeholders (producer, consumer, Microgrid operator etc.) in a Microgrid are proposed under this framework. Finally, a global Microgrid development roadmap is envisaged taking into account of regional differences as well as potential technology advancements in future.
