Development of a bioactive film from fruit seed waste for shelf life extension of tomato (Solanum lycopersicum )

Abstract

The global annual production of tomatoes is estimated to be 162 million tons every year. China is the world's largest producer of tomatoes with 50 million tons, followed by India with 17.5 million tons (Sarma, 2018). Tomatoes are consumed in the fresh state or as processed products, they are quite rich in nutrients such as carbohydrates, fiber, amino acids, organic acids, vitamins A, C, and E, minerals, and phenolics. It is epidemiologically proven that phenolics and their resultant antioxidants play a vital role in terms of reducing the risk of heart diseases and aiding in boosting the immune system (Ozturk & Ozer, 2019).According to the consumers, the unique flavor and aroma possessed by the commodity are the primary shelf life and quality indicating parameters (Beaulieu et al., 2004). These sensorial characteristics rely on balancing complex factors such as sugar content, volatile compounds, and organic acids (Gemma et al., 2011). Tomatoes are highly perishable commodities that encounter severe postharvest losses throughout the food supply chain's transportation, storage, and marketing stages, causing harm to both producers and consumers (Nasrin et al., 2009).The postharvest losses as a result of unfavorable weather conditions, disease and pests, damage during harvest, delay in harvest, damage during transportation, lack of market, and damage during

Smart packaging—An overview of concepts and applications in various food industries

“…The incorporation of Azadirachta indica, Annona squamosa, and Carica papaya seed extracts into bio-based film extends the shelf-life of tomatoes up to 13 days by inhibiting the spoilage-causing microorganisms. Kadirvel et al (2022) 8. Lettuce (Lactuca sativa)…”
