- W45028195 abstract "꼬막 패각 회화분을 이용하여 칼슘 보조제로서 사용 할 수 있는 젖산칼슘과 구연산칼슘을 제조하였으며, ammonium chloride process(ACP) ammonium nitrate process(ANP)법을 적용하여 이들의 순도를 높이기 위한 실험을 하였다. 꼬막 패각 회화분을 젖산용액과 구연산용액과 반응시켜 얻은 젖산칼슘과 구연산칼슘의 순도는 각 용액의 농도에 따라 각각 $94.35-96.72%$ 와 $87.58-93.06%$ 이었다. 꼬막 패각 회화분에 ACP법 혹은 ANP법을 적용하여 정제한 탄산칼슘으로 제조한 젖산칼슘과 구연산칼슘의 순도는 각 용액의 농도에 따라 각각 $99.53-100.34%$ 와 $99.32-99.88%$ 를 나타내어 꼬막 패각 회화분을 직접 이용하여 제조한 것보다 순도가 상당히 높아졌으며, 식품첨가물공전의 규격기준에 적합한 칼슘제제를 얻을 수 있었다 꼬막 패각 회화분으로 제조한 젖산칼슘과 구연산칼슘의 백색도는 각각 91.8과 92.9이었으나 ACP법 혹은 ANP법을 적용한 경우는 각각 94.8-98.5와 99.4-101.5로서 높은 값을 나타내었다. 따라서 폐기물로 버려지는 꼬막 패각 회화분에 ACP법과 ANP법을 적용하여 정제한 탄산칼슘으로 제조한 젖산칼슘과 구연산칼슘은 순도와 백색도에서 우수한 것으로 판단되었다. 【Ash of Anadarac tegillarca granosa shell was used for preparation of calcium lactate and calcium citrate, and improvement of their purity was carried out by using ammonium chloride process (ACP) and ammonium nitrate process (ACP). Purity of calcium lactate and calcium citrate made by the reaction of ash of Anadarac tegillarca granosa shell with lactic acid solution and with citric acid solution was 94.35-96.72 and $87.58-93.06%$ , respectively. However, purity of calcium lactate and calcium citrate prepared with purified calcium carbonate pre-purified from the ash of Anadarac fegiliarca granosa shell using ACP and ANP method was 99.53-100.34 and $99.32-99.88%$ , respectively. The purity of these calcium products were higher than those of calcium lactate and calcium citrate made with ash of Anadarac tegillarca granosa shell. Whiteness of calcium lactate and calcium citrate prepared with purified calcium carbonate pre-purified using ACP and ANP method was 94.8-98.5 and 99.4-101.5, respectively. Whiteness of these calcium products was higher than that of calcium lactate (91.8) and calcium citrate (92.9) made with the ash of Anadarac tegillarca granosa shell. Therefore, we estimated that calcium lactate and calcium citrate prepared with purified calcium carbonate using ACP and ANP method could be used potentially as a food additive for calcium supplement.】" @default.
