Special Issue Information

Dear Colleague,

Due to its vital role for human life, health and well-being, the food and drink industry is among the world’s paramount sectors and keeps the lead in terms of turnover, employment and number of companies. To produce healthy and tasty foods and beverages, food engineering employs a vast diversity of technologies, which range from traditional processing modes, known from millennia, to the most advanced and groundbreaking achievements of today’s science. Nevertheless, food engineering is often rather underestimated as a forefront of knowledge and remains not so attractive for the younger generations, as compared with high-tech branches. ‘Once my grandma cooks so well, what innovations could be expected there?’, many people think.

Hence, the Special Issue ‘New Frontiers in Food Engineering’ is designed to fill in the aforementioned gap by spotlighting recent progress in the food and drink supply chains from Farm to Fork (e.g. production, packaging, storage, transport, distribution and household handling). The issue welcomes original research and review paper contributions focusing on the interaction between foods and food manufacturing and handling systems. For instance, the thematic scope covers (but is not limited to) the following topics:

  • Engineering properties of foods and food ingredients;
  • Heat transfer, fluid flow, process innovation and intensification;
  • Biochemical and microbiological phenomena, safety, quality and shelf life;
  • Modelling and simulation of food production and preservation processes;
  • Sensors, measurements, quality control and traceability along the food chain;
  • Thermal and refrigerated processing and preservation;
  • Non-thermal, unconventional and alternative processing;
  • Hygienic engineering and design, cleaning and sanitation;
  • Packaging, MAP, biodegradable and intelligent packaging;
  • Energy and economic efficiency of food production and preservation equipment;
  • Environmentally friendly and circular food engineering;
  • Integration of renewable energy throughout the food chain;
  • Carbon-neutral and sustainable food manufacturing and handling systems;
  • Digitalisation and cybersecurity of food supply chains;
  • Food engineering policy, state-of-the-art and future trends.

In general, the concerned topics should address the UN Sustainable Development Goals and the EU Green Deal. The authorship will be of particular interest to all food scientists, researchers, technologists and engineers who are required to publish their professional findings through Open Access. It is also anticipated to publish the Special Issue as a dedicated book to be promoted and distributed worldwide via Amazon, eBookMall, Apple books, etc.

By means of the porous media theory, computational fluid dynamic models of heat transfer and fluid flow at different pack stacking modes in a refrigerated room are elaborated. A practical case is simulated, where brick-shaped packs with aquatic products, partially frozen to 261.15 K, are loaded in the room to complete the freezing process down to 255.15 K, followed by long-term frozen food storage at the latter standard temperature. The best freezing completion effect (defined as the maximum reduction of the highest product temperature during a certain residence time) is achieved by using the pyramidal stacking mode whose upper package is in the center of four lower packages (UPF-PSM) with two piles. The highest temperature of aquatic products at a two-pile-UPF-PSM can be reduced from 261.15 to 255.60 K for a residence time of 24 h. Within the same time, the product temperature becomes most uniform at a UPF-PSM. Simultaneously, the best uniformity of flow distribution and highest efficiency of air circulation in a refrigerated room are obtained by using the neat stacking mode (NSM) during the long-term frozen storage. Furthermore, a comprehensive stacking mode is proposed (using UPF-PSM for freezing completion and NSM for long-term frozen storage), which enhances both the freezing completion effect and the efficiency of air circulation in the studied refrigerated room.

This contribution elaborates on a futuristic hybrid concept for the multifunctional employment of a liquid air energy storage (LAES) system for combined heat, cold and power production (tri-generation) in a food factory, thereby providing a substantial part of the energy demand for various unit operations and enhancing the round-trip efficiency (RTE) of LAES. A processing line for frozen French fries, with relatively high heating and refrigeration demands, is used as a case study. The total useful energy output per charge/discharge cycle is 61,677 kWh (i.e., 38,295 kWh of electricity, 19,278 kWh of heating, and 4104 kWh of refrigeration). The estimated tri-generation RTE of the studied system reaches 55.63%, which appears to be 1.2 times higher than the RTE of a classical standalone LAES system with the same power input, considered as a baseline. In a broader context, such a performance enhancement by amalgamating food and energy technologies can make cryogenic energy storage a more viable grid balancing option capable of substantially increasing the share of renewables in the energy supply mix.
