Comparison of actual meals with nutrition standards. Every 10 days or monthly, the record shows whether children and patients receive the required amounts of milk, meat, vegetables and other food groups, and where the diet differs from the standard.
The diet control sheet shows where actual meals differ from the standard by food group and helps adjust the next period's menu.

The same file the service provides to an inspector. The data is fictional: the organization “Ромашка” and five employees.
Required fields: Period; Food group; Required and actually issued amounts per person; Percentage deviation and note. An empty field is equivalent to an incomplete log for an inspector, so use a dash deliberately and include an explanation.
According to the schedule, rather than daily: the frequency is set in the production control programme and must match the actual records.
SanPiN 2.3/2.4.4282-26. Include the regulatory reference on the title page so the inspector can immediately see why the log is kept.
Yes. SanPiN 2.3/2.4.4282-26 does not require paper: the important points are being able to see who made an entry and when, and preventing unnoticed retrospective changes. For an inspection, print the electronic log for the required period.
Inspectors usually request records for the last 12 months, so one year is a practical minimum. Keep logs connected with a food poisoning investigation or a complaint until the proceedings are closed.
