Stimuli-responsive bio-based polymeric systems are gaining considerable attention as intelligent versatile tools that show great potential in various fields. In this review, an overview is given of recent developments of stimuli-responsive bio-based polymeric systems. The characteristics of bio-based polymers in different applications are discussed and the superiority of these advanced stimuli-responsive bio-based polymeric systems is highlighted. Furthermore, several emerging applications of these systems including intelligent drug delivery, responsive food packaging and smart water treatment are discussed and the section of intelligent drug delivery is emphasized in detail. Finally, the respective prospects and limitations inherent to these systems are addressed.

Stimuli-responsive bio-based polymeric systems and their applications

Background Modern food supply chains are complex and contain numerous stakeholders, with each performing specific roles pertaining to food production. As food supply chains become more complex, the importance of food production transparency increases. Several factors contribute to the need for transparency such as an increase in the global population, detection of foodborne illness outbreaks, efficient management of risks and recalls, and satisfying consumer demand. A case in point is the necessity that food production systems become more sustainable through improvements in production efficiency and reducing the wasting of resources and food. Other examples include the need for timely identification of the source of food production, in addition to requiring a more rapid knowledge of the cause of contamination during outbreaks of foodborne illness. Scope and approach This review sets out to describe enabling technologies, provided by the Internet of Things (IoT), which have the potential to increase food production transparency. In addition, other technologies important for managing and using food supply chain data, such as blockchain and Big Data analytics, are reviewed. The IoT is the overarching technology which allows for data collection from multiple phases within supply chains leading to data driven transparent systems of food production. Key findings and conclusions Enabling transparency in food supply chains via implementation of technologies will require considerable effort from all stakeholders involved, resulting in many new challenges and requirements that must be addressed. These challenges and requirements range from technical issues, such as Internet connection, storage requirements, device security, and government requirements and regulations, to those concerning consumer acceptance.

Adulteration in food has been a concern since the beginning of civilization, as it not only decreases the quality of food products but also results in a number of ill effects on health. Authentic testing of food and adulterant detection of various food products is required for value assessment and to assure consumer protection against fraudulent activities. Through this review we intend to compile different types of adulterations made in different food items, the health risks imposed by these adulterants and detection methods available for them. Concerns about food safety and regulation have ensured the development of various techniques like physical, biochemical/immunological and molecular techniques, for adulterant detection in food. Molecular methods are more preferable when it comes to detection of biological adulterants in food, although physical and biochemical techniques are preferable for detection of other adulterants in food.

Food adulteration: Sources, health risks, and detection methods.

Background: Bionanotechnology, as a tool for incorporation of biological molecules into nanoartifacts, is gaining more and more importance in the field of food packaging. It offers an advanced expectation of food packaging that can ensure longer shelf life of products and safer packaging with improved food quality and traceability. Scope and approach: This review recent focuses on advances in food nanopackaging, including bio-based, improved, active, and smart packaging. Special emphasis is placed on bio-based packaging, including biodegradable packaging and biocompatible packaging, which presents an alternative to most commonly used non-degradable polymer materials. Safety and environmental concerns of (bio)nanotechnology implementation in food packaging were also discussed including new EU directives. Conclusions: The use of nanoparticles and nanocomposites in food packaging increases the mechanical strength and properties of the water and oxygen barrier of packaging and may provide other benefits such as antimicrobial activity and light-blocking properties. Concerns about the migration of nanoparticles from packaging to food have been expressed, but migration tests and risk assessment are unclear. Presumed toxicity, lack of additional data from clinical trials and risk assessment studies limit the use of nanomaterials in the food packaging sector. Therefore, an assessment of benefits and risks must be defined.
