Food quality and safety are key aspects to guarantee that foods reach consumers in optimal conditions from the point of view of freshness and microbiology. Nanotechnology offers significant potential to secure or even enhance these aspects. Novel technologies, such as nanofabrication and nanoencapsulation, can provide new added value solutions for the fortification of foods with bioactives and targeted controlled release in the gut. Nanomaterials can also support food preservation aspects by being added directly into a food matrix or into food contact materials such as packaging. Thus, nanomaterials can be leveraged in the form of nanocomposites in food packaging design by melt compounding, solvent casting, lamination or electrohydrodynamic processing (EHDP) to promote passive, active, and even bioactive properties such as barrier, antimicrobial, antioxidant, and oxygen scavenging roles and the controlled release of functional ingredients. These attributes can be exerted either by the intended or non-intended migration of the nanomaterials or by the active substances they may carry. Lastly, nanomaterials can be advantageously applied to provide unique opportunities in Circular Bioeconomy strategies in relation to the valorization of, for instance, agro-industrial wastes and food processing by-products.

Fish is an inevitable part of Kerala’s food style and around 3% of the State’s economy is attributed to Fisheries. The recent news that hit the headlines of Kerala was the seizing of formalin laced fish from many parts of Kerala. There are numerous conventional chemical methods for detecting formalin concentration in fish. The main drawback is that the majority of these techniques are time-consuming, tedious and destructive that requires welltrained operators and cannot be applied for on-field detection. In this current paper, the hazardous effects of formalin in human body, traditional methods used at present and the recently developed novel techniques for effective detection of formaldehyde concentration in fish, are analyzed. An overview of the conventional methods- chemical methods and microbial attributes are discussed. The novel techniques include high performance liquid chromatography (HPLC), electrochemical biosensors, catalytic kinetic flurimetry technique, fluorescence spectroscopy, photonic crystal fiber based sensor, enhanced Raman spectroscopy (SERS) technique and optical fiber bundle sensor. Also, the advantages of these techniques over traditional methods are pointed out. The novel techniques exhibit good linearity, stability, sensitivity, non-invasive, non-destructive and most of them have the potential to be developed as a portable device. Using this non-destructive technique, unethical means of food preservation can be monitored, thereby ensuring fish quality in Kerala. Even though there has been great advancement in this field, traditional methods are still dominant in practical applications. It is high time that new techniques find their way out, because the quality of fish consumed by the people of this State is decreasing by a quick rate. Therefore, further efforts are necessary to facilitate early adoption of novel technologies in the fish industry and promote their standardization to complement or replace current legislation standards for the evaluation of fish quality.

The light-emitting diode (LED) is an advanced technology with a wide range of applications in our day-to-day life. It has numerous advantages over conventional light, such as controlling the spectrum of light, the specificity of the wavelength, cool emitting surface, and cost-effectiveness. The novel technologies and developments have proved the efficacy of LEDs in eliminating microbes rather than being an effective lighting source. The LED employs Photodynamic Inactivation to eliminate micro-organisms with the help of various photo-sensitizers. Photodynamic inactivation is a non-chemical based technique that helps fight against the microbes without developing the resistant microbial strains. The illumination of LED at a specific narrow wavelength exhibits antimicrobial activity against a wide range of microbes, including resistant strains. Getting rid of harmful micro-organisms is one of the effective ways to reduce health risks and promote quality of life. Hence, the LEDs with specific narrow wavelengths can be employed to sterilize the medical equipment, healthcare environment, and food preservation without using chemicals. The Photodynamic Inactivation using LED as a light source will be a promising source for eradicating harmful micro-organisms, including nosocomial and foodborne pathogens.

Ikan asin adalah metode untuk pengawetan makanan menggunakan kombinasi penggaraman dan pengeringan matahari. Di kalangan masyarakat, pembuatan ikan asin banyak menggunakan bahan kimia berbahaya seperti formalin. Penambahan bahan berbahaya mempengaruhi kualitas terutama keamanan. Makanan yang aman didefinisikan sebagai makanan yang terbebas dari cemaran biologi, kimia, mikrobiologi, yang dapat mempengaruhi kesehatan. Karbon aktif diduga bersifat polar yang mampu mengadsorpsi formalin. Tujuan penelitian ini adalah untuk mengetahui pengaruh pemberian karbon aktif dalam mengurangi cemaran formalin pada “jambal roti”. Rancangan percobaan yang digunakan untuk percobaan yaitu Rancangan Acak Lengkap (RAL) 2 faktorial, dengan faktor pertama yaitu konsentrasi karbon aktif 0, 3, dan 6% serta perlakuan kedua yaitu lama perebusan selama 5, 10, dan 15 menit. Penelitian ini dimulai dari pembuatan “jambal roti” dengan penambahan formalin dan perebusan dengan karbon aktif kemudian dianalisis uji kadar formalin, NaCl, protein, dan air. Hasil penelitian menunjukkan bahwa konsentrasi karbon aktif dan lama perebusan memberikan pengaruh yang signifikan pada kualitas jambal roti. Semakin tinggi konsentrasi karbon aktif dan lama perebusan maka semakin berkurangnya kadar formalin pada jambal roti. Hasil terbaik penelitian ini adalah karbon aktif 6% dan lama perebusan 15 menit. Menghasilkan formalin 3.21 ppm, NaCl 9.40%, protein 42.00%, dan air 30.02%. Kata kunci: Karbon Aktif, Formalin, Jambal Roti, Lama Perebusan. ABSTRACT                 Salted fish was a method for food preservation using combination of salting and sun drying. Among the people, the manufacture of salted fish use hazardous chemical material such as formaldehyde. The addition of hazardous substances affects the quality especially the safety. Safe food define as food that free from biological, chemical, microbiological contaminants that can affect health. Active carbon suspected to be polar which able to adsorb formaldehyde. The purpose of this research was to determine the influence of active carbon in reducing formaldehyde in salted fish “jambal roti”. The research used completely randomized design (CRD) with 2 factors, the first factor was the concentration of active carbon 0, 3, and 6% and the second was the boiling time (for 5, 10, and 15 min). This research was started from making “jambal roti” with the addition of formaldehyde and boiling with active carbon then analyzed for formaldehyde content, NaCl, protein, and moisture. The result showed that the concentration of active carbon and boiling time had a significant effect in quality salted fish “jambal roti”. The higher the concentration of active carbon and boiling time the more formaldehyde in “jambal roti” were removed. The best results of the research was 6% active carbon and 15 min of boiling time. Resulting 3.21 ppm of formaldehyde, 9.40% of NaCl, 42.00% of protein, and 30.02% of moisture. Keywords: Active Carbon, Formaldehyde, Jambal Roti, Boiling Time

Border Zones

I argue that we are entering an automated era of border control that I label a border-biosecurity industrial complex. Funded in great part by the Department of Homeland Security (DHS), scientific research and automated surveillance technologies promise the state innovative and supposedly unbiased solutions to the challenge of border control and security. This article spotlights a border surveillance technology called AVATAR (Automated Virtual Agent for Truth Assessment in Real-Time). Analyzing this technology, which was funded by the DHS and developed by faculty at the University of Arizona’s National Center for Border Security and Immigration (BORDERS), allows me to assess how the emphasis on novel technologies to detect terrorists unleashes the search for ubiquitous surveillance devices programmed to detect deviant behavioral and physiological movements. I offer a wider view of this technology-in-the-making by analyzing how university research in aerial defense, the psychology of deception, the life sciences, and computer engineering influences the development of surveillance devices and techniques. I explore how, during a posthuman era, automated technologies detect and racialize “suspect life” under the guise of scientific neutrality and supposedly free from human interference. Suspect life refers to the racial bias preprogrammed into algorithms that compute danger or risk into certain human movements and regions such as border zones. As these technologies turn the body into matter, they present biological life as a more scientifically verifiable truth than human verbal testimony, moving border control from the adjudication of law through the subjective interview to the automated body that speaks a truth more powerful than a complex story can tell.

New Phase

Examining the activities of the Israel Defense Forces along the Gaza-Israel border, this article identifies a new phase in what the author calls ‘military-police fusion’. The analysis focuses on novel technologies—remote-controlled weapon stations and unmanned ground vehicles—and on the women soldiers who operate these systems. The central claim is that the blurring of boundaries between military and policing missions, combined with high-tech weaponry, has resulted in the development and implementation of new modes of violence that are currently undergoing a process of redefinition and feminization. The article addresses three key dimensions of the processes occurring in the hybrid operational environment along the Gaza-Israel border: the legal dimension, the technological dimension, and the gender dimension.
