Use of Potassium Sorbate and Natamycin to Inhibit the Growth and Aflatoxin Production of Aspergillus parasiticus 299 in Improved Binagol

Lutgada S. Palomar and Lloyd B. Bullerman ABSTRACT Binagol (pH 6.3) was reformulated using lemon juice to lower the pH to 5.5, 5.0 and 4.5. Sensory evaluation was done to determine the acceptability of the binagol with lower pH, using the original binagol at pH 6.3 as the control. Sensory evaluation showed binagol can be …
