Abstract (english)
In continuation of our efforts to fully utilize eggshell waste (ESW), here we report the possibility of ESW transformation to calcium chloride (CaCl2) anhydride of food-grade additive purity and eggshell membranes (ESMs) as potential enzyme immobilization carriers. ESW chemical transformation by 5% (w/v) hydrochloric acid to CaCl2 solution and ESM completely devoid of the remnants of ESW calcium carbonate was performed in the constructed 15 L batch reactor during 4 h at room temperature, followed by separation of ESM from CaCl2 solution by filtration. ESW derived CaCl2 solution containing the excess hydrochloric acid was neutralized by adding calcium hydroxide, concentrated to approximately 1/8th of volume, and spray dried. Separated ESM was washed with water and acetone, dried, and ground to a size of less than 0.5mm. The ESW transformation process produced 102.42 ± 3.31 g of CaCl2 anhydrous and 2.48 ± 0.28 g of ESM per 100 g of ESW dry matter. ESW derived CaCl2 fulfilled all criteria for food-grade additive, while obtained ESM showed their suitability for Burkholderia cepacia lipase immobilization by adsorption.
