Abstract

The increasing demand for sustainable and high-quality food sources has led to a growing interest in exploring alternative protein options. Fish-derived products, known for their nutritional value, unique flavor profiles, and potential health benefits, have gained significant attention. Among these, snakehead (Channa striata) and its by-products have emerged as promising resources for various food applications, including fish powder production. Fish powder holds immense potential in the food industry as a versatile ingredient, capable of enhancing nutritional content while minimizing waste. This research focuses on investigating the fatty acid composition and volatile compounds present in snakehead fish powder and its by-products. The study employs a combination of analytical techniques, namely gas chromatography-mass spectrometry (GC-MS) and lipid extraction methods, to identify and quantify fatty acids and volatile compounds in the fish powder samples, providing a comprehensive chemical profile. The data reveals variations in the fatty acid composition among different components of the snakehead powder samples, influenced by the fish's feeding habits. The presence of essential fatty acids, including omega-3 and omega-6, highlights the potential health benefits of consuming snakehead powder. Moreover, the identification of odd chain saturated fatty acids (OCS-FAs) in the samples indicates their potential contribution to human health. Notably, snakehead powder contains docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), which have reported preventive effects on human coronary artery disease. In conclusion, snakehead powder is a valuable source of protein and essential fatty acids, with potential implications for human health. The study emphasizes the significance of incorporating polyunsaturated fatty acids (PUFAs) into the human diet, potentially through fish powder consumption. Overall, the findings highlight the potential benefits of snakehead meat, head, skin, and bone, encouraging the development of functional food products and their potential use in preventing stunting.

Abstract

As the global population ages, there is a growing emphasis on addressing the dietary needs and overall well-being of older individuals. Bibliometric analysis of existing literature on food innovation for the elderly helps identify research trends and gaps, guiding future exploration to better meet the nutritional needs and preferences of this population. The aim of this research is to examine the literature on food and nutrition for older adults through bibliometric analysis. Data was gathered on April 19th, 2024, from the Scopus database by using the search term "elder* AND food". Articles were restricted to specific subject areas and then analyzed using VOSviewer and descriptive statistics. A total of 746 articles published between 1951 and 2024 were discovered, with a notable rise in publications in the past decade. The United States ranked first in the number of published articles, followed by South Korea and Brazil. Keywords were grouped into 11 clusters, encompassing themes such as diet quality, food security, nutritional status, and elderly care. The analysis underscored the global importance of research on elderly nutrition, underscoring the necessity for international cooperation. Recent developments revealed a concentration on food-based dietary guidelines and the management of food bolus for older individuals. The study also addressed limitations, such as potential biases arising from relying on Scopus and excluding non-English publications.
