SEQUESTERING AND BUFFERING AGENTS (ACIDS, BASES AND SALTS) Sequestering agents are substances which prevent adverse effect of metals catalysing the oxidative breakdown of foods forming chelates; thus inhibiting decolourisation, off taste and rancidity. Buffering agents are materials used to counter acidic and alkaline changes during storage or processing steps, thus improving the flavour and increasing the stability of foods.
ANY READY MADE FOOD PURCHAGED FROM MARKET WILL HAVE PRESERVATIVES, PESTICIDES, BUFFERING AGENS, COLOR, FAVOURS, ANTI-OXIDENTS, ADULTERATED SUBSTANCE
