The rise of junk food is a global phenomenon that has reshaped modern dietary habits. From fast food chains to convenience snacks, processed and calorie-dense options are now more accessible than ever. The term "junk food" typically refers to foods high in fats, sugars, and salt but low in essential nutrients. As lifestyles have become busier, people often choose convenience over nutrition, contributing to the increasing popularity of these foods. Advertising, urbanization, and economic growth have also played a major role in promoting fast food culture. With attractive packaging, catchy jingles, and wide availability, junk food has become a staple, especially among children and young adults. Unfortunately, while junk food offers short-term satisfaction, it poses serious long-term health risks. As consumption grows, so do concerns about public health, food quality, and disease. Understanding the reasons behind its rise is essential to curbing its harmful effects. Several key...

High-pressure processing (HPP) is a non-thermal preservation technique that uses high hydrostatic pressure (typically 100–600 MPa) to inactivate pathogens while preserving food quality. In plant-based food systems , HPP is gaining attention for its ability to improve safety, shelf life, and textural quality without compromising nutritional attributes. Unlike thermal methods, HPP does not denature sensitive vitamins or bioactives, making it highly suitable for clean-label products. Its influence on protein functionality in plant-derived foods is particularly notable, affecting solubility, emulsification, gelling, and digestibility. As plant-based proteins are often less functional than animal-derived counterparts, enhancing their properties via HPP provides an innovative approach to meeting consumer demand for meat and dairy alternatives. This paragraph introduces HPP’s relevance in the growing plant-based food industry and sets the stage for a deeper look at its specific impact on pr...

Traditional fermented foods have been consumed for centuries across cultures, valued not only for their unique taste and preservation qualities but also for their significant health benefits. These foods are produced through the metabolic activity of microorganisms such as bacteria, yeast, and molds. During fermentation, these microbes break down sugars and other compounds, enhancing the food's digestibility and nutritional value. In traditional societies , fermented products like yogurt, idli, kimchi, sauerkraut, and tempeh are integral to the daily diet. Modern science is now validating the health-promoting properties of these foods, making them relevant in contemporary nutrition. One of the most prominent nutritional advantages of fermented foods is the presence of probiotics—live beneficial bacteria that support gut health. These probiotics help maintain intestinal flora balance, improve digestion, and strengthen immune function. Traditional methods of fermentation often prese...

Food spoilage is a significant global challenge that leads to economic losses, health risks, and environmental concerns due to food waste. Traditional methods for spoilage detection like visual inspection or expiration date are often unreliable and subjective. In response, researchers are increasingly turning to smart sensor technologies that provide real-time, accurate detection of spoilage, ensuring food quality and safety. These systems can monitor microbial activity, temperature changes, and chemical markers to determine food freshness. Working Principle of Smart Spoilage Sensors Smart sensors detect spoilage by identifying specific biological , chemical, or physical changes in the food or its surrounding environment. For example, as food deteriorates, it releases gases such as ammonia, hydrogen sulfide, or carbon dioxide, which are detectable using gas-sensitive materials like metal oxide semiconductors or colorimetric dyes. Other sensors rely on pH shifts, moisture changes, or e...
