"We strongly reiterate that at no stage of the manufacturing process, ash is added to Maggi noodles," a Nestle India spokesperson said in a statement.
In June 2015, the food regulator FSSAI had banned Maggi noodles, saying the product was "unsafe and hazardous" for consumption after finding lead levels beyond permissible limits.
Nestle relaunched Maggi noodles in the market in November 2015 after fulfilling conditions set by the Bombay High Court which lifted the ban imposed by the FSSAI.
"While we have not yet received the order passed by the Adjudication Officer, we understand from the information available that the relevant samples are of the year 2015 and the issue pertains to 'Ash content'," the spokesperson said, adding the instant noodles are compliant with the new rules laid by the Food Safety and Standards Authority of India.
