Abstract:
The insects are the major cause of post-harvest losses of grain that can be a positive cause of many human health issues. Insects infestation in flour can cause significant changes in the quality of Pearl millet flour (PMF). The present study focuses on the fragment shedding behaviour of Rhyzopertha dominica and Sitophilus oryzae on PMF. The FDA (Food and Drug Administration) has given the DAL (Defect Action Level), i.e. 75 insect fragments per 50 gram of flour. The standard acid hydrolysis method was used to calculate the fragment counts in PMF. The results indicate that the fragments shed by R. dominica and S. oryzae insects in PMF at 30 ºC with 35 days of storage duration were - R. dominica shed 34.00±3.05, 120.00±5.50, and 220.00±53.48 fragments, respectively for 1, 3, and 5 number of infestation. The S. oryzae shed 22.00±1.00, 59.00±6.24, and 78.00±10.39 fragments, respectively, for 1, 3, and 5 insect infestations. The R. dominica crossed the DAL in 21 and 14 days in 3 and 5 insect-infested PMF. The S. oryzae crossed the DAL in 35 days in 5 insect-infested PMF.

The S. oryzae shed 22.00±1.00, 59.00±6.24, and 78.00±10.39 fragments, respectively, for 1, 3, and 5 insect infestations. The R. dominica crossed the DAL in 21 and 14 days in 3 and 5 insect-infested PMF. The S. oryzae crossed the DAL in 35 days in 5 insect-infested PMF.
The result from the current study indicates that even three insects can degrade the quality of the PMF. A frequent sampling at adequate intervals of time and post-harvest processing within 13 days after harvesting is required (results demonstrated that till 13th day PMF was under the acceptable limit, below DAL) to retain the quality and control the insect infestation and its fragments shredding in PMF.
