This paper reports on the development, standardization, and application of instrumental as well as radiochemical neutron activation analysis (INAA and RNAA) techniques for determining the concentrations of iron, zinc, cobalt, cesium, strontium, selenium, thorium, and calcium in food consumed in India. Based on the analysis of 20 diet samples, prepared as per the data on dietary intake patterns of an adult in four provinces of India and that of an average adult Indian, the geometric mean (GM) intake of various elements for the reference Indian man was estimated to be 15.
This review aims to address the current data on edible packaging systems used in food production. The growing global population, changes in the climate and dietary patterns, and the increasing need for environmental protection, have created an increasing demand for waste-free food production. The need for durable and sustainable packaging materials has become significant in order to avoid food waste and environmental pollution. Edible packaging has emerged as a promising solution to extend the shelf life of food products and reduce dependence on petroleum-based resources. This review analyzes the history, production methods, barrier properties, types, and additives of edible packaging systems. The review highlights the advantages and importance of edible packaging materials and describes how they can improve sustainability measures. The market value of edible packaging materials is expanding. Further research on and developments in edible food packaging materials are needed to increase sustainable, eco-friendly packaging practices that are significant for environmental protection and food safety.
