不同管理的巴厘岛屠宰场(RPH)的巴厘牛肉屠宰质量Quality of Bali Beef Cut on Different Management of Slaughterhouses (RPH) in Bali Province
2 grams of meat sample were weighed and wrapped in filter paper and put in a lead, dried in an oven for 9 hours at a temperature of 1050C. The soxtherm tube was dried in an oven for 3 hours at 1050C, then cooled in a desiccator and weighed (B). The lead containing the sample after being dried was put into a soxtherm tube, filled the soxtherm tube with 200 ml of n-Hexane until the sample was completely immersed. Extraction for 4 hours in a soxtherm apparatus, then air dry the soxtherm tube in a forced oven for 15 minutes then dry for 3 hours in a dry oven at 1050C, cool in a desiccator for 30 minutes, weigh the soxtherm tube containing fat extract.
0.3克样品,1克催化剂,5毫升浓硫酸,消化1.5小时。
A total of 0.3 grams of sample, was placed in a vapodest tube and added 1 grain of selenium catalyst and 5 ml of concentrated H2SO4, then carried out destruction (heating in a boiling state) for 1.5 hours until the solution is clear. After cooling, 50 ml of distilled water and 20 ml of 40% NaOH were added, then distilled. The results of the distillation were accommodated in an Erlenmeyer flask containing a mixture of 20 ml H3BO3 and 2 drops of pink green bromine cresol. After the distillate volume (distillate) became 100 ml and turned bluish in color, the distillation was stopped and the distillate was titrated with 0.1 N HCL until pink.
