Objective: Although unemployment is mostly considered as an economic and social problem, unemployment duration in this manner is usually more important than rate of unemployment and absolute number of unemployed. Hence, it is possible to imagine the conditions that high rate of unemployment and short term unemployment duration occurs at the same time. This paper aims to seek those factors ...
The effects of post-processing treatments on sensory quality and reduction of Shiga toxigenic Escherichia coli (STEC) in three formulations of two types of dry-fermented sausage (DFS; salami and morr) were evaluated. Tested interventions provided only marginal changes in sensory preference and characteristics. Total STEC reductions in heat treated DFS (32°C, 6days or 43°C, 24h) were from 3.5 to...
Bacterial biofilms were exposed to electrolysis by making the steel substratum an electrode in a circuit including a 6-V battery. These treatments resulted in killing (2.1-log reduction) and removal (4.0-log reduction) of viable cells at the anode and cathode, respectively, within a few minutes.
در طی زمان نگهداری وحمل ونقل فیله منجمد ماهیان بسته بندی شده در شرایط خلا، شرایط دما ممکن است ایده ال نباشد. این شرایط منجر به کاهش کیفیت میکروبی و شیمیایی محصولات می شود. در این بررسی کیفیت میکروبی و شیمیایی فیله های منجمد ماهی حلوا سفید و شیر بسته بندی شده در شرایط خلاء در فروشگاههای اهواز مورد بررسی قرار گرفت. شمارش باکتریهای مزوفیلیک و بی هوازی به ترتیب در محدوده g/ log cfu86/5-48/2 ، g / l...
The fate of Listeria monocytogenes, Salmonella typhimurium, or Escherichia coli O157:H7 were separately monitored both in and on soudjouk. Fermentation and drying alone reduced numbers of L. monocytogenes by 0.07 and 0.74 log(10)CFU/g for sausages fermented to pH 5.3 and 4.8, respectively, whereas numbers of S. typhimurium and E. coli O157:H7 were reduced by 1.52 and 3.51 log(10)CFU/g and 0.03 ...
BACKGROUND The timing of antiviral therapy cessation in hepatitis B e antigen (HBeAg)-negative patients is controversial. Here, we aimed to investigate the role of HBV DNA and hepatitis B surface antigen (HBsAg) monitoring to predict off-treatment sustained response. METHODS A total of 53 HBeAg-negative chronic hepatitis B patients who received lamivudine for 34 ±23 (range 12-76) months and h...
