Trails To Improve The Sanitary Status of Raw Edible Offal

A total of 4 kg of buffalo and camel edible offal(2kg liver and2kg heart) were divided into 4 groups ,each of them half kg.First group (control), second group was treated with sterileD.W, third group was treated with trisodium phosphate (10%) andfourth group was treated with L.A (2%) and they were examinedchemically and microbiologically every two days underrefrigeration storage at 4±1•C till sings of spoilage.J-Chemlcal examination (PH measurement) :As pH considers an indicator of spoilage, so it was a necessaryto determined pH value every time before the samples weresubjected to microbiological examination.A) liver samples:The mean pH values were 6.36±0.6 and 6.3±.03 for control anddipped in distaled water samples for buffalo liver at 3rd day ofexamination while in camel samples they were 6.07±0.07 and6. 13±0. 13 . By the s” day of storage only TSP and L.A treatedsample still fit and pH were 6.3±0.06 and 6.25±0.15 in buffalosamples, while in camel samples they were 6.15±0.14 and5.97±0.09 which considered acceptable. But after previouslymentioned periods the mean pH values exceeded less than 6indicating the decomposition.B) Heart sampleThe mean pH values were 6.57 ±0.03, 6.47±0.03 and 6.63±0.03 for control, distaled water and TSP (10%) treated samples forbuffalo samples at 3rd day of storage while in camel samples theywere 6.43±0.09, 6.3±0.1 and 6.67±0.03. By the 5th day only lactic
