"No further extension will be given," a bench headed by Acting Chief Justice B D Ahmed firmly told the Food Safety and Standards Authority of India (FSSAI).
Terming the non-filing of draft guidelines by the Centre as "unfortunate", the court asked the FSSAI to submit it within 10 days.
Earlier, Additional Solicitor General Rajeeve Mehra had assured the court that the draft guidelines would be filed by July this year.
"It is expected that parties shall adhere to this time line and no extension would be given by this court," it said, adding that the Centre would share the report with other stakeholders who will also give their suggestions or comments on the issue.
It had also said that after the draft guidelines were prepared, the food processing companies would be consulted for their opinions and then the final guidelines will be made.
The court was hearing a PIL filed by Rakesh Prabhakar, a lawyer for NGO 'Uday Foundation', seeking a direction banning sale of junk food and aerated drinks in and around schools.
