Eggs are one of the most nutritious products on a daily basis. The objective of present research is to investigate the impact of coatings on improving storage time and internal quality of eggs. Coating treatments included control (C), coated with chickpea protein isolate (CPI), coated with PI containing Satureja hortensis (CPISH), coated with PI containing Satureja mutica (CPISM). Internal quality was assessed by air cell depth, shell strength, weight loss, haugh unit, yolk and albumen pH, yolk index, microbial evaluation and scanning electron microscope. The weight loss increased during storage and its highest value was 6.12%. Edible coatings (CPI, CPISH, CPISM) preserved internal quality according to the haugh unit, yolk index and pH over 4 weeks (20 °C) compared with C. Haugh unit (5.04), yolk index (0.31), albumen (9.51) and yolk pH (7.04) were detected in C after 7 weeks. CPISH and CPISM protected shell is observed by scanning electron microscope and these coatings affected the internal quality and were appropriate alternatives to extend storage.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
