تستهلك سورية ١٢٨ ألف طن من المنظفات، تبلغ نسبة المساحيق الإنزيمية ٣٥ % ، تضاف إليها
الإنزيمات بمعدل ٥ و ٠-١ % . يستخدم في المنظفات الأميلاز، الليباز، البروتيآز، و السلولآز. و بما أن
الإنزيمات هي بروتينات تقوم بدور المحفز الحيوي في تفكيك المكونات الغذائية، فإن فعاليتها تتأثر
بالحرارة و بمكونات المنظفات، و بخاصة المؤكسدات و المبيضات.
جرى في هذا البحث تطبيق طريقة فولجموت Volgemyta المستخدمة في تحليل أميلاز اللعاب
و الدم، على تحليل أميلاز المنظفات المنتشرة في السوق المحلية، و على تحليل الأميلاز التجاري مع الماء،
و محلول كلور الصوديوم ١ و ٠ %، و مع المحلول الفيزيولوجي. كما درس تأثير المنظفات في فعالية
الأميلاز، و بينا أن إضافة أي كمية جديدة من الأميلاز لاتجدي نفعا" في زيادة القدرة التنظيفية.
Syria consumes as many as ١٢٨ thousand tons of detergents yearly. The
powder detergent with added enzyme represents is about ٣٥ % of the total
production .The enzyme content in the detergent is ٠,٥-١,٠ %. Amylases,
Lipases, Proteases, and cellulases are the main enzymes used in detergents.
Enzymes are known to have protein structure and play role in biocatalysts
during the cleaning process. Enzyme activity is affected by heat and the
detergent s components such as oxidants, bleachers, and brighters.
This research was focused on using Volgemyta method, which traditionally
used for saliva and blood analyses to determent the Amylase activity in
detergents produced in Syria. The result in dicate that this setteed may be used
to determent the commercial Amylase activity in water, and in ٠,١ % Sodium
chloride water solution, and finally in physiological solutions . The effect of the
different detergents on the Amylase activity has been studied as well. As a
result, the addition of any extra amount of Amylase makes no increase or
improvement in the cleaning performance of the detergent.
