Milk is a rich source of multiple bioactive peptides that not only help to fulfill consumers 'nutritional requirements but also play a significant role in preventing several health disorders. Understanding the chemical composition of milk and its products is critical for producing consistent and high-quality dairy products and functional dairy ingredients. Over the last two decades, peptides have gained significant attention by scientific evidence for its beneficial health impacts besides their established nutrient value. Increasing awareness of essential milk proteins has facilitated the development of novel milk protein products that are progressively required for nutritional benefits. The need to better understand the beneficial effects of milk-protein derived peptides has, therefore, led to the development of analytical approaches for the isolation, separation and identification of bioactive pep...

It was observed that there was a progressive increase in the physiological loss in weight and total soluble solids, while the fruit firmness exhibited continuous decrease throughout the storage time. The fruits treated with 0.75 mM salicylic acid enhanced shelf life as evident from the delayed increase in PLW and decrease in fruit firmness.The tomato fruits expressed the change in colour according to the biological chart of USDA (1991) during storage period. The treated fruits, especially at concentrations 0.75 mM and 1.0 mM, showed the delay in colour change. The results obtained in the present research indicated that the 0.75 mM concentration of SA was most effective in delaying the ripening related morphological changes.

Every year approx. 25-40% tomato losses occur due to lack of suitable methods of post-harvest storage. Salicylic acid has high potential in monitoring post-harvest losses as a natural and safe phenolic compound. Therefore, the present research was planned to study the effect of salicylic acid (0.5 mM, 0.75 mM, 1.0 mM, 1.25 mM and 1.5 mM) on the biochemical changes in tomato cultivar Hisar-Arun at turning stage during storage at room temperature. A progressive increase in physiological loss in weight, total soluble solids, lycopene content, β-carotene content, total sugars, reducing sugars and non-reducing sugars was observed. The results suggested that 0.75 mM concentration of salicylic acid was most effective in delaying the ripening related physico-biochemical changes. Hence, exogenous application of salicylic acid is an effective approach in enhancing the shelf life of tomato fruits upto 4 to 6 days.

Increasing Climate change make worse the risks of hunger and undernutrition through Extreme weather events. Climate change increases the frequency and intensity of some disasters such as droughts, floods and storms. This has an adverse impact on livelihoods and food security. Climate-related disasters have the potential to destroy crops, critical infrastructure, and key community assets, therefore deteriorating livelihoods and exacerbating poverty. Long-term and gradual climate risks cause, Sea-level rise as a result of climate change, affecting livelihoods in coastal areas and river deltas. Accelerated glacial melt will also affect the quantity and reliability of water available and change patterns of flooding and drought. Climate change affects all dimensions of food security and nutrition. Changes in climatic conditions have already affected the production of some staple crops, and future climate change threatens to exacerbate this. Higher temperatures will have an impact on yields while changes in rainfall could affect both crop quality and quantity. Climate change could increase the prices of major crops in some regions. For the most vulnerable people, lower agricultural output means lower incomes. Under these conditions, the poorest people who already use most of their income on food sacrifice additional income and other assets to meet their nutritional requirements, or resort to poor coping strategies.
