Data of manuscript Insect chitosan as a natural antimicrobial against vegetative cells of Bacillus cereus in a cooked rice matrix [DATASET]

This study investigates the antimicrobial activity of insect chitosan against vegetative cells of Bacillus cereus in a rice matrix. Sample culture solutions were prepared with different concentrations of insect chitosan (150, 180, 220 and 250 µg / mL) and tested at three temperatures (30 ºC, 20 ºC a...

Sample culture solutions were prepared with different concentrations of insect chitosan (150, 180, 220 and 250 µg / mL) and tested at three temperatures (30 ºC, 20 ºC and 10 ºC), which simulate different storage temperature scenarios of precooked rice. The results indicate that insect chitosan has antimicrobial activity that depends on temperature and chitosan concentration. For the assays with chitosan at 10 ºC, all concentrations were bactericidal during the study time, reaching a maximum inactivation of 6 log cycles for 250 µg / mL. At 20 ºC and at 30ºC a bacteriostatic activity was observed for concentrations of 150 µg / mL and 180 µg / mL. Results also showed that concentrations of 220 µg / mL and 250 µg / mL were bactericidal for all the temperatures tested during the storage time. When rice is cooked and not stored at an appropriate temperature, below 10 ºC, the consumer’s health is at risk. In these cases, insect chitosan could be a good additional control measure to control B. cereus growth and toxin formation in cooked rice.TRACE-RICE project, Reference Number AMD-1934-1 and grant PID2020-116318RB-C31 funded by MCIN/AEI/10.13039/501100011033.Peer reviewedDIGITAL.CSICMinisterio de Ciencia, Innovación y Universidades (España)Agencia Estatal de Investigación (España)European CommissionRodrigo Aliaga, D.
