2 Demanding of minimally processed foods and foodstuffs, which retain natural flavor, color, texture, nutritional characteristics, and contain fewer additives. Nitrite is a key ingredient of cooked meats. nitrous acid may react with amines in muscle foods to form N-nitroso compounds especially nitrosamines, which have toxic, mutagenic, neuro-, and nephrotoxic, and carcinogenic effects The objective of the present study was to reduce nitrite content in hot dogs using hurdle technology without sacrificing product safety and quality.

4 1. Water activity (aw) measurement ( Thermoconstanter model TH 200 ) 2. Color measurement ( HunterLab; Labscan 5000 spectrocolorimeter) L = lightness a = redness b = yellowness 3. Chemical analyses pH (pH meter, Model pH 209) Nitrite content ISO 2918 4. Microbiological analyses 5. Sensory analyses 6. Statistical analyses ( MSTATC software)

5 Acidity ( pH) hurdle (<5.4) Processing temperature ( Fvalue ) hurdle (80 ±1) Storage temperature ( tvalue) hurdle (<10) Extrinsic hurdles Water activity (aw) hurdle (0.95)

9 The obvious conclusion to be drawn from the findings is that a significant reduction in nitrite content on meat products such as hot dogs can be achieved using combined treatments sensibly without technological, microbiological, nutritional, legislative, and sensory problems.
