Use of encapsulated natural compounds as antimicrobial additives in food packaging: A brief review

BackgroundSynthetic chemical preservatives in food can be harmful to human health. These problems have increasingly attracted concern and interest from researchers, which has led to the study and application of non-toxic essential oils with preservative ability in food products and food packaging. A great challenge in this sense is their facile degradation during processing of the food and manufacturing processes during food packing.Scope and approachEncapsulation is an interesting technique to improve the physical-chemical and microbiological stability of these essential oils, as well as to achieve controlled release. This review provides a detailed overview of encapsulation in the food industry, focusing on the application of procedures to encapsulate antimicrobial essential oils.Key findings and conclusionsThis review focuses on recent studies related to nanotechnology and the nano and microencapsulation of essential oils. This study provides valuable insight that may be useful for identifying trends in the commercialization of nanotechnological products or for identifying new research areas. The results published to date confirm that the encapsulation promotes the protection of active compounds, enabling industrial applications of active packaging.

Non-thermal technologies and its current and future application in the food industry: a review

In recent years, consumers have been demanding convenient and healthy foods which have ‘fresh-like’ characteristics while still being safe and a long shelf-life. These requirements are hard to achieve using existing traditional thermal food processing technologies and the innovative new food process and preservation technologies based on thermal processing systems are needed. However, non-thermal technologies in food processing do not generate high temperature and use short treatment times. This means that the nutritional components of foodstuffs are better retained, and the sensory properties of foods are less changed compared with traditional thermal processing. The aim of this review was to present non-thermal technologies applications and its mechanism in food industry in recently, and to explore the potential application prospects of combining non-thermal treatments applied in food industry because it not only could overcomes the drawback of single technology, but also can enhances the processing efficiency at lower treatment intensity.     

Application of atomic force microscopy as a nanotechnology tool in food science

Atomic force microscopy (AFM) provides a method for detecting nanoscale structural information. First, this review explains the fundamentals of AFM, including principle, manipulation, and analysis. Applications of AFM are then reported in food science and technology research, including qualitative macromolecule and polymer imaging, complicated or quantitative structure analysis, molecular interaction, molecular manipulation, surface topography, and nanofood characterization. The results suggested that AFM could bring insightful knowledge on food properties, and the AFM analysis could be used to illustrate some mechanisms of property changes during processing and storage. However, the current difficulty in applying AFM to food research is lacking appropriate methodology for different food systems. Better understanding of AFM technology and developing corresponding methodology for complicated food systems would lead to a more in-depth understanding of food properties at macromolecular levels and enlarge their applications. The AFM results could greatly improve the food processing and storage technologies.     

The use of exergetic indicators in the food industry – A review

Assessment of sustainability will become more relevant for the food industry in the years to come. Analysis based on exergy, including the use of exergetic indicators and Grassmann diagrams, is a useful tool for the quantitative and qualitative assessment of the efficiency of industrial food chains. In this paper, we review the methodology of exergy analysis and the exergetic indicators that are most appropriate for use in the food industry. The challenges of applying exergy analysis in industrial food chains and the specific features of food processes are also discussed.     

Trends and challenges of biopolymer-based nanocomposites in food packaging

The ultimate goal of new food packaging technologies, in addition to maintaining the quality and safety of food for the consumer, is to consider environmental concerns and reduce its impacts. In this regard, one of the solutions is to use eco-friendly biopolymers instead of conventional petroleum-based polymers. However, the challenges of using biopolymers in the food packaging industry should be carefully evaluated, and techniques to eliminate or minimize their disadvantages should be investigated. Many studies have been conducted to improve the properties of biopolymer-based packaging materials to produce a favorable product for the food industry. This article reviews the structure of biopolymer-based materials and discusses the trends and challenges of using these materials in food packaging technologies with the focus on nanotechnology and based on recent studies.

Algae in food: a general review

Abstract

Algae are common all over the Earth. Due to their rich chemical composition and content of bioactive substances they have been used in many fields of industry. Their gelling, thickening and stabilizing properties have led to the development of such products as agar, alginate and carrageenan. Moreover, algae are used in the food industry as food supplements and an addition to functional food. Algae are also added to meat products, such as pasty, steaks, frankfurters and sausages, as well as to fish, fish products, and oils, to improve their quality. Cereal-based products, such as pasta, flour and bread, are another group of products enriched with algae. Due to their properties algae may also be used for construction of fermented functional food. Fermented products containing algae are, most of all, dairy products, such as cheese, cream, milk deserts, yoghurt, cottage cheese, and processed cheese. Combination of fermented products offering a high content of lactic acid bacteria with algae possessing biologically active metabolites of natural origin allows not only to compose products with a high content of nutrients, but also to create a brand new segment of fermented food.

Food ethics: a decision making tool for the food industry?

The modern food industry is able to exercise great power and influence over society. It acts as an agent of social change and, consequently, functions as a form of moral agent. Although the industry as a whole may be thought of as `the' moral agent, the moral and ethical standing of the industry is a reflection of the moral and ethical values of the executives who lead the businesses that constitute the industry. With increasing competitiveness in the food marketplace, the use of developments in science and technology to create new food products, and the distancing of consumers from practical involvement with food, other than eating, many issues arise which must be managed sensitively if the food industry's conduct and place in society is to be seen as morally acceptable and ethically supportable. These issues are issues of food ethics. Some issues in food ethics are considered and food ethics is proposed as a tool for decision making within the food industry, for the benefit of people and society, and the food industry itself.
