Abstract
This paper presents the preparation of white bread with different hen eggshell powder additions. The aim of this paper is to resolve at least two important aspects: the waste recovery from food industry and fortification of white bread with minerals (calcium). The addition of eggshell powder to the white bread preparation was up to 2% and an increase in bread quality was on elasticity and humidity starting with 0.5% eggshell powder addition. Bread aging occurred 10 to 12 h after its baking. After 24 h, all physico-chemical properties of bread crust and crumb in the case of fortified bread with calcium had a positive effect.
Highlights
Generation products and processes are guided by sustainable ecology, eco-efficiency and green chemistry [1]
Current scientific researches from food industry, biotechnologies, green chemistry are focused on using of unconventional materials for obtaining functional foods, bioactive compounds, food ingredients, etc. [2,3,4,5,6,7]
Due to a high consumption of hen eggs, a large amount of egg waste is discarded, some studies being focused on eggshell-derived components as a renewable resource
Summary
Generation products and processes are guided by sustainable ecology, eco-efficiency and green chemistry [1]. Current scientific researches from food industry, biotechnologies, green chemistry are focused on using of unconventional materials for obtaining functional foods, bioactive compounds, food ingredients, etc. Due to a high consumption of hen eggs, a large amount of egg waste is discarded, some studies being focused on eggshell-derived components as a renewable resource. This massive amount of waste could potentially be used in different applications by offering great material for industrial and structural applications. Eggshell is a natural bio-ceramic composite, with a combination of both inorganic and organic components that have exceptional characteristics. The unique chemical composition and substantial availability make eggshells a potential source for bio-based calcium carbonate [8]
