Viable and Industrial Need for Improved Processing Technologies

By: , Posted on: November 3, 2016

It is recognized that a major threat to human health in Europe is that of chronic diseases and obesity with great negative impact on life quality. The quality and health beneficial effects of food consumed are an important key to tackle these challenges either by developing and offering new and healthier food raw material or through development of healthy food ingredients to be included in meals on a daily basis. Thus, consumer´s growing interest to obtain products of greater organoleptic and nutritional quality with healthy properties has led to the food industry and academics to develop new strategies in product development and food processing.

Conventional heat treatments have been shown as a perfect tool to achieve adequate food security, however as well-known may have detrimental effect on quality and nutritional value.

Consumers acceptance is a major issue and bioactive compounds derived from or naturally present in foods provides a solution that meets the general consumer’s demand for natural components. For this reason, every day is driving the development and research in the new non-thermal technologies such as high hydrostatic pressure, pulsed electric fields, etc. that can achieve microbial inactivation, better health properties (natural nutrient retention, improving bioavailability, etc.), preserving the organoleptic properties, and preventing the formation of potentially harmful products. Moreover, these technologies can be used for designing new products with different textures and with improved functional properties.

Some of these technologies are a fact (eg. HP and PEF) with several units commercialized around the World. However, high costs are still a challenge for the new processing technologies, wherefore the industrial application and implementation of these technologies is still behind. Providing more information to both academics and industry is the key to increase the awareness of the technologies in order to investigate the possibilities for the implementation of these processing technologies for the future high-quality foods. The EU-project “Mechanistic modelling of the formation of bioactive compounds in HP-processed seedlings of Brussels sprouts for effective solution to preserve healthy compounds in vegetables” is currently running aiming at providing new insights into the mechanism behind the HP impact on vegetable and plant matrices that are necessary for the development of viable future HP industrial application. The chapter 7 “Implementation of emerging technologies” (by F.J. Barba, V. Orlien, M.J. Mota, R.P. Lopes, S.A. Pereira, J.A. Saraiva In Innovation Strategies in the Food Industry) provides insight into the well-established and most promising technologies (HP, PEF, OH, MW, US) of industrial application and commercialization. Moreover, specific food cases (orange juice, milk, and oysters) regarding implementation of HP and PEF in an industrial setting are surveyed. In the future, the costs are expected to reduce with further technological advances and thereby increase the implementation in the food industry.

To this line, the Chapter 14 “Cost and safety issues of emerging technologies against conventional techniques” (by C.M. Galanakis, F.J. Barba, and K.N. Prasad In Food Waste Recovery: Processing Technologies and Industrial Techniques) provides an attempt to clarify cost and safety issues of emerging, non-thermal technologies applied in food processing. More insights about the effect of these techniques in food components can be found in the forthcoming (January 2017) book entitled “Nutraceutical and Functional Food Components: Effects of Innovative Processing Techniques” (see below).

nutraceutical and functional food components

Nutraceutical and Functional Food Components: Effects of Innovative Processing Techniques presents the latest information on the chemistry, biochemistry, toxicology, health effects, and nutrition characteristics of food components and the recent trends and practices that the food industry (e.g. the implementation of non-thermal technologies, nanoencapsulation, new extraction techniques, and new sources, like by-products, etc.) has adopted. This book fills the gap in knowledge by denoting the impact of recent food industry advances in different parameters of food components (e.g. nutritional value, physical and chemical properties, bioavailability and bioaccessibility characteristics) and final products (e.g. applications, shelf-life, sensory characteristics).

Key Features

  • Provides a holistic view of the interactions between novel processing techniques and food components

  • Covers food applications, shelf-life, and sensory characteristics

innovation strategies in the food industry

Innovation Strategies in the Food Industry: Tools for Implementation is an indispensable resource for the food industry to introduce innovations in the market, stand out from the competition and satisfy consumer demands. This reference reports the most trend advances of the food science, while providing insights and ideas to overcome limitations for their actual implementation in the industry. Innovation Strategies in the Food Industry: Tools for Implementation fills the gap between strategy developers and technical R&D associates by interpreting the technological adequacy of innovative techniques with the reaction of related consumers. It deals with the interaction of academia and industry, describing innovation and long term R&D strategies to overcome bottlenecks during know-how transfer between these two sectors.

Key Features

  • Reports the development of cooperative networks for the commercialization of new food products
  • Includes the concept of open innovation, denoting the particular issues that SMEs are facing during their innovation efforts and suggest respective innovation policies in the agrifood sector
  • Discusses the challenges of introducing innovations in traditional food products
  • Describes the sustainability problems and restrictions (safety and energy issues) of innovations in food processing and emerging technologies
  • Exploits the cutting-edge innovation cases of  food science and their applications in the food industry
  • Addresses the observed problems and provides solutions to meet market and consumers’ needs

food waste recovery

Food Waste Recovery: Processing Technologies and Industrial Techniques acts as a guide to recover valuable components of food by-products and recycle them inside the food chain, in an economic and sustainable way. The book investigates all the relevant recovery issues and compares different techniques to help you advance your research and develop new applications. Strong coverage of the different technologies is included, while keeping a balance between the characteristics of current conventional and emerging technologies. This is an essential reference for research outcomes. A video presentation of the book can be viewed here.

Key features
