The aim of the study was focused on extraction of fleshing oil from limed fleshings with different neutralization process by ammonium chloride (NH4Cl) and hydrochloric acid (HCl) followed by solvent extraction. The production of fatty acid methyl esters (FAMEs) from limed fleshing oil by two stage process has also been investigated. The central composite design (CCD) was used to study the effect of process variables viz., amount of flesh, particle size and time of fleshing oil extraction. The maximum yield of fleshing oil from limed fleshings post neutralization by ammonium chloride (NH4Cl) and hydrochloric acid (HCl) was 26.32g and 12.43g obtained at 200g of flesh, with a particle size of 3.90mm in the time period of 2h. Gas chromatography analysis reveals that the biodiesel (FAME) obtained from limed fleshings is rich in oleic and palmitic acids with weight percentages 46.6 and 32.2 respectively. The resulting biodiesel was characterized for its physio-chemical properties of diesel as per international standards (EN14214).
本研究的目的是专注于从石灰处理肉中提取油脂，采用氯化铵（NH4Cl）和盐酸（HCl）进行不同的中和过程，然后进行溶剂萃取。还研究了从石灰处理油中通过两段法生产脂肪酸甲酯（FAMEs）。采用中心组合设计（CCD）研究了加工变量（肉量、粒度和油脂提取时间）的影响。用氯化铵（NH4Cl）和盐酸（HCl）中和后，从石灰处理肉中获得最大油脂产率为 26.32g 和 12.43g，在 2h 的时间内，肉量为 200g，粒度为 3.90mm。气相色谱分析表明，从石灰处理肉中获得的生物柴油（FAME）富含油酸和棕榈酸，重量百分比分别为 46.6%和 32.2%。所得生物柴油的理化性质按照国际标准（EN14214）进行了柴油特性的表征。
