Summary
Restricting children's exposures to marketing of unhealthy foods and beverages is a global obesity prevention priority. Monitoring marketing exposures supports informed policymaking. This ...study presents a global overview of children's television advertising exposure to healthy and unhealthy products. Twenty‐two countries contributed data, captured between 2008 and 2017. Advertisements were coded for the nature of foods and beverages, using the 2015 World Health Organization (WHO) Europe Nutrient Profile Model (should be permitted/not‐permitted to be advertised). Peak viewing times were defined as the top five hour timeslots for children. On average, there were four times more advertisements for foods/beverages that should not be permitted than for permitted foods/beverages. The frequency of food/beverages advertisements that should not be permitted per hour was higher during peak viewing times compared with other times (P < 0.001). During peak viewing times, food and beverage advertisements that should not be permitted were higher in countries with industry self‐regulatory programmes for responsible advertising compared with countries with no policies. Globally, children are exposed to a large volume of television advertisements for unhealthy foods and beverages, despite the implementation of food industry programmes. Governments should enact regulation to protect children from television advertising of unhealthy products that undermine their health.
The quality of the manufactured product plays a special role in the food industry. Food producers, in addition to meeting consumer requirements, are obliged to comply with legally sanctioned, ...rigorous requirements of hygiene and cleanliness at work, as well as the way it is performed. In order to maintain the legally required hygiene rules in production plants specializing in the production of food products, manufacturers implement numerous management systems aimed at maintaining legally imposed guidelines in the field of quality management and occupational health. The article describes the use of the DPMO indicator, which allows for a thorough analysis of process parameters affecting the final quality of the manufactured product. For the analyzed process, the maximum DPMO value for one of the areas is 636364. In nine cases, which constitutes 12.5% of the total, DPMO is 0. The purpose of this article is to identify non-compliances in the field of occupational hygiene in the production plant analyzed using the DPMO indicator and then to introduce improvements. The developed recommendations concern marking, standardization and responsibility for individual processes as well as additional cleanliness inspections.

New food packaging materials provide an attractive option for the advancement of nanomaterials. The poor thermal, mechanical, chemical, and physical properties of biopolymers and their inherent ...permeability to gases and vapor have increased this interest. Polymeric materials (matrix) in modern technologies require a filler, which can react/interact with the available matrix to provide a new formulation with improved packaging properties including oxygen permeability, moisture permeability, crystalline structure, barrier properties, morphology, thermal stability, optical properties, anti-microbial characteristics, and mechanical properties. The performance of nanocomposite films and packaging is dependent on the size of the nanofillers used and the uniformity of the nanoparticles (NPs) distribution and dispersion in the matrix. Advancement in nanocomposite technologies is expected to grow with the advent of sustainable, low price, environmentally friendly materials with an enhanced performance. The current review addresses advances in the biopolymeric nanocomposites as alternatives to petroleum plastics in the food packaging industry. It also provides a brief description of biopolymer nanocomposite films and gives general information about different metal NPs with an emphasis on their influence on the emerging characteristics of biodegradable films. The results of recent reports provide a better understanding of the influence of metal NPs in food packaging.
Sustainable utilization of agri-food wastes and by-products for producing value-added products (for cosmetic, pharmaceutical or food industrial applications) provides an opportunity for earning ...additional income for the dependent industrial sector. Besides, effective valorisation of wastes/by-products can efficiently help in reducing environmental stress by decreasing unwarranted pollution. The major focus of this review is to provide comprehensive information on valorisation of agri-food wastes and by-products with focus laid on bioactive compounds and bioactivity. The review covers the bioactives identified from wastes and by-products of plants (fruits, exotic fruits, vegetables and seeds), animals (dairy and meat) and marine (fish, shellfish seaweeds) resources. Further, insights on the present status and future challenges of sustainably utilizing agri-food wastes/by-products for value addition will be highlighted.
Directed evolution has advanced into a standard industrial “tool” to tailor naturally occurring proteins for a variety of biotechnological applications, thus enabling product valorization and ...bringing societal benefits across industrial sectors. Examples are sustainable enzymatic production processes for chemicals, pharmaceuticals, or applications in the food, feed, and laundry industries. In essence, directed evolution has contributed to sustainable industrial processes that fuel the transition from a fossil‐based economy to a biobased economy utilizing renewable resources. Phage display technologies represent a comparable breakthrough that allow for the directed evolution of binding proteins by physical coupling between a phenotype and the respective genotype, thus enabling the identification of highly selective antibodies for a broad variety of applications in diagnostics and therapy.
One half of The Nobel Prize for Chemistry 2018 was awarded to Frances H. Arnold for the directed evolution of enzymes, and the other half jointly to George P. Smith and Sir Gregory P. Winter for the phage display of peptides and antibodies. This Highlight acknowledges the impact of the Nobel Laureates contributions and summarizes the history, state of the art, challenges, and applications of directed evolution and phage display.
Currently, most biotechnological products are based on microbial conversion of carbohydrate substrates that are predominantly generated from sugar- or starch-containing plants. However, direct ...competitive uses of these feedstocks in the food and feed industry represent a dilemma, so using alternative carbon sources has become increasingly important in industrial biotechnology. A promising alternative carbon source that may be generated in substantial amounts from lignocellulosic biomass and C1 gases is acetate. This review discusses the underexploited potential of acetate to become a next-generation platform substrate in future industrial biotechnology and summarizes alternative sources and routes for acetate production. Furthermore, biotechnological aspects of microbial acetate utilization and the state of the art of biotechnological acetate conversion into value-added bioproducts are highlighted.
The search for alternative carbon sources in industrial biotechnology is driven by the competing use of commonly used sugar-based substrates in the food and feed industry.Acetate represents a highly attractive, alternative microbial carbon source for industrial biotechnology.The most interesting routes to alternatively generate acetate comprise the depolymerization of lignocellulosic materials and the Wood-Ljungdahl pathway of acetogenic bacteria to produce acetate as the main product via gas fermentation, microbial electrosynthesis, or microbial photosynthesis.Acetate and acetate-containing streams have emerged as promising carbon sources for microorganisms to produce a variety of value-added bioproducts, such as platform chemicals (e.g., succinic acid), microbial lipids, bioplastics (e.g., polyhydroxyalkanoates), and biosurfactants (e.g., rhamnolipids).
Microwave radiation has the ability to heat a material with dielectric properties. Material absorbs microwave energy and then converts it into heat, which gives the possibility of a wide use of ...microwaves in many industry sectors or agricultural sciences. Microwaves are especially widely used in food industry. The main objective of this paper is to present an overview of recent development regarding microwave applications in food industry. Many techniques in food processing (pasteurization, sterilization, drying, thawing, blanching and stunning) are assisted by microwave energy. It should be mentioned also the use of microwaves in nutrients and nutraceuticals production. Waste generation is an integral part of food production. Microwaves have also application in wastes management. The results of experiments, factors affecting heating and their practical application have been discussed. Many cases have been compared with conventional process methods. The use of microwaves shows many advantages. The most important aspect is shortening the time of the thermal process (even by 50%) and reducing the costs of the operation. In addition, it allows to increase the efficiency of processes while maintaining high quality. The examples of microwave applications given in the article are environmentally- friendly because the conditions of thermal processing allow for reducing the use of solvents and the amount of sewage by decreasing the demand for water. It is anticipated that microwaves will become increasingly popular, with the development of new microwave technologies solving many problems in the future.
The food sector has a prodigious focus and is constantly gaining in importance in today’s global economic marketplace. Due to an increasing global population, society faces a greater challenge for ...sustainable food production, quality, distribution, and food safety in the food supply chain. Adopting green supply chain management (GSCM) elements is essential for utilizing the food supply chain in an environmentally benign way. As a solution to the above challenge, the economic and green characteristics for supplier selection in green purchasing are studied in this paper. For an organization, the evaluation and selection of the green supplier is a vital issue due to several tangible and intangible criteria involved. Accordingly, we apply multiple criteria decision aiding techniques.
We propose a hybrid approach that combines the revised Simos procedure, PROMETHEE methods, algorithms for constructing a group compromise ranking, and robustness analysis. At first, the revised Simos procedure is used to derive the criteria weights. Next, the PROMETHEE method is applied to rank the suppliers according to each Decision Maker׳s (DM׳s) preferences. Then, the compromise ranking is constructed to minimize the distance of the individual׳s rankings from the solution adopted by the whole group. For this purpose, we introduce and apply some original procedures based on Binary Linear Programming. Finally, the results are validated against the outcomes of robustness analysis. The applicability and efficiency of the proposed approach is endorsed with a case study in an Indian food industry.

Food safety is becoming increasingly important because food industry must provide quality products to minimize the health risks. Traditional methods to assure food safety, such as plate count and ...polymerase chain reaction are accurate and robust but can hardly satisfy the needs of the food industry because they are costly and time consuming. Therefore, optical biosensors that can analyze food in a low-cost, facile, fast, sensitive, and selective manner started to emerge.
This review presents plasmonic biosensors including surface plasmon resonance (SPR), localized SPR (LSPR), fiber optic SPR (FO-SPR), surface enhanced Raman scattering (SERS), surface-enhanced fluorescence (SEF), and total internal reflection (TIR) based sensors and their applications in food pathogens monitoring. Moreover, the strengths and weaknesses of plasmonic biosensors implementation in food control are showcased.
Plasmonic biosensors could simplify procedure and radically reduce time, price and consummation of reactants, compared to traditional microbiological methods. Optical biosensors, in particular SPR, have been developed for detection of different foodborne pathogens. In parallel, analytical improvements have been achieved by coupling different techniques (fiber optics, Raman, fluorescence, luminescence) to plasmonic sensors in order to reduce the limits of detection and to improve sensitivity. The future improvements include the miniaturization of instruments to handheld devices and simplification of analysis to enable direct target detection in food matrices. Plasmonic technology can certainly have long lasting impact because the need for a simple and rapid food assay is pressing and guarantees the future development in this field.
•The fundamental of plasmonic sensors was ascribed.•Application and basic strategies of plasmonic biosensors for food analysis was reviewed.•Trends in material, ligands and functionalization of plasmonic biosensors were summarized.•Sensitivity and specificity improving for practical applications is presented.
