The ingredients are being saved in the database. The database has a limit on how long the text in each field can be. If you add more ingredients than the database can handle an error will pop up since the database will automatically cut out the last part of the data.
If you are using a UTF-8 Language like arabic, then you will reach this limit quicker.
To solve this open the sql database in phpmyadmin, and just go to recipes-> structure and increase the ingredients field size.
