Hi Salam,

You can try CapColors® from Chr Hansen. They work for confectionary applications, though not so well for beverages as they will settle down after storage.

Not experienced enough to answer your other question on microbial issue, but Hurdle Technology might be the way to go if you are staying away from preservatives.

Hi Salam,

Have you considered using Sodium metabisulphite (E223) as this will inhibit yeat and mould. for sauces and will also inhibit Gram -ve. You may have to use two preservatives synergistically to give optimum results. Potassium sorbate is a better option.

With regards Food Whitening you are better speaking to food colour supplies such as CHR Hansen etc.

Dear Dr Ajay shah,


This was a new developed sauce ( with sesame paste) ,so pottassium sorbate is not giving good results.Next time we will try with E223.

Thanks.:thumbup:

Hi Salam,

Too bad CapColors did not work for you. Hope some other coloring companies are able to offer other alternatives to you.

As for microbial issues, I recently came across a posting on LinkedIn, introducing natural antimicrobial. Maybe you can take a look and contact the person in charge for some samples.
