They include whole foods like oats and soy, fortified foods like vitamin-enriched milk, and enhanced foods like dairy products with added probiotics. These foods contribute to overall well-being and disease prevention when consumed regularly.| Food Safety Institute
Restriction endonucleases, also known as molecular scissors, cut DNA at specific recognition sites, producing fragments with either sticky or blunt ends. They are classified into five types based on their structure and activity, with Type II enzymes being the most commonly used in cloning. These enzymes are vital for generating DNA fragments that can be recombined into new genetic constructs.| Food Safety Institute
Toxicants are stored in various tissues such as plasma proteins, liver, kidneys, adipose tissue, and bone. Storage can protect organs temporarily, but chronic release can lead to prolonged intoxication. For example, fat-soluble toxicants accumulate in adipose tissue, while metals like lead are stored in bones.| Food Safety Institute
Concepts are mental images or general ideas derived through the process of deduction and used as building blocks for theories. Constructs are specialized concepts adopted for scientific purposes, often defined in a way that can be measured and observed. Variables are attributes that can take different values and are essential in research for representing and analyzing changes. Understanding these terminologies is crucial for framing research studies and developing hypotheses.| Food Safety Institute
Clause 3 of ISO 19011:2002 defines key audit terms such as audit, audit criteria, audit evidence, and audit findings. It differentiates between types of audits (internal, external, combined, joint) and clarifies roles such as auditor, auditee, and audit client. This foundational terminology ensures clear communication and understanding throughout the audit process.| Food Safety Institute
Food spoilage is influenced by intrinsic factors like water activity, pH, and nutrient content, and extrinsic factors such as temperature, humidity, and oxygen availability. Microbial growth depends on these factors, with different organisms thriving under specific conditions. Controlling these factors through methods like refrigeration, drying, and packaging can significantly extend the shelf life of food products.| Food Safety Institute
The globalization of food trade has increased the risk of foodborne infections due to the introduction of new hazards like prions, genetically modified foods, and dioxin-contaminated foods. Prions, associated with diseases like Creutzfeldt-Jakob Disease and Bovine Spongiform Encephalopathy, are resistant to denaturation and cause severe neurological damage. Dioxins, industrial pollutants, bio-accumulate in fat and pose carcinogenic and developmental risks. Genetically modified foods raise con...| Food Safety Institute
This section outlines the critical hygienic and sanitary practices that must be implemented by food processing units to ensure food safety and quality. These practices include maintaining clean facilities, using sanitized equipment, and ensuring that personnel follow stringent hygiene protocols. The focus is on preventing contamination at every stage of food processing, from raw material handling to final packaging. Proper waste disposal, pest control, and regular inspections are also emphasi...| Food Safety Institute
Food processing involves transforming raw materials into products with extended shelf life and improved quality. This includes primary, secondary, and tertiary processing stages. India, a major food producer, has potential for significant value addition, though currently low. Enhancing processing technologies can reduce waste and meet growing consumer demands for processed foods.| Food Safety Institute
Quality assurance in food processing involves systematic procedures to ensure that products meet specified safety and quality standards. This section discusses various quality assurance practices, including Good Manufacturing Practices (GMP), Hazard Analysis Critical Control Point (HACCP), and Total Quality Management (TQM). These practices help in identifying potential hazards, establishing critical control points, and monitoring processes to prevent food safety issues. Regular audits, emplo...| Food Safety and Quality Institute
