The question in front of a school canteen operator is not whether to put mortadella on the menu, but which folder to answer parents and inspectors with. For a school canteen mortadella sandwich the two critical criteria are salt and portion; the third is documentation. If a product that meets all three can also be prepared quickly during break, the decision is complete.
The three products in this article are Mortella Chicken Mortadella with Vegetables 1350 g, the log; Mortella Sliced Chicken Mortadella with Vegetables (200/450 g); and Mortella Sliced Chicken Jambon (100/200/450 g). The first two share one recipe and carry 1.5 g of salt per 100 g; the chicken jambon is higher on salt at 2.5 g and stronger on protein at 20.6 g. Which one goes into the canteen sandwich is settled by the criteria below. This article claims no regulation or ministry rule; it explains how a canteen builds its own file.
In a school canteen mortadella sandwich, salt is the first question and portion the second
Salt comes first because a canteen customer should not get the day's salt from a single meal, and that query comes from parents. Chicken mortadella with vegetables carries the lowest salt figure in the Mortella charcuterie line at 1.5 g per 100 g; for comparison, sliced chicken jambon is 2.5 g and sliced turkey jambon 3 g. At the same weight, mortadella delivers a little over half the salt of a jambon.
Portion comes second because a canteen sandwich is small and its price is fixed. A worked example: at a 15 g slice, two slices make 30 g of mortadella and that portion carries roughly 0.45 g of salt. Three slices make 45 g and roughly 0.68 g. If the canteen stays at two slices, both portion cost and salt stay under control, and because the vegetable pieces show in the cross-section, even two slices make the sandwich look full.
Why does vegetable chicken mortadella come ahead of chicken jambon in a canteen sandwich?
For three reasons. The first is salt: 1.5 g against 2.5 g. The second is visibility: green and orange pieces of vegetable on the emulsion base give a child a recognisable picture and make the product easier to accept. The third is slicing behaviour: the emulsion structure can be sliced very thin without falling apart in the sandwich, and two thin slices cover the bread.
Chicken jambon still stays on the list. It carries 20.6 g of protein and 2.8 g of fat per 100 g, its cured texture is soft, and its 120-day shelf life gives stock security in periods when the canteen cannot take a weekly delivery. A canteen can rotate the two: mortadella three days a week, chicken jambon two. In a high-school canteen that wants more protein, the jambon's share goes up; in a primary-school canteen the salt criterion brings mortadella forward. The product selection guide for canteen and cafeteria operators applies the same rotation logic to the other items.
How many grams should the mortadella portion be in a school canteen sandwich?
Two slices, roughly 30 g. That figure comes from the canteen's own arithmetic rather than from any regulation: sandwich price, bread size and the daily salt target. The portion is written as a slice count, and no scale is used during break. On the first day two slices are weighed from a tray, the grams go on the form, and the recipe reads "2 slices".
A canteen using the log fixes the slice thickness on the machine in the 1 to 2 mm range; a thick slice inflates both the portion and the salt. In a canteen using tray packs the thickness was fixed in production and only the count is set. A worked example: a canteen making 150 sandwiches a day at two slices uses 300 slices, roughly 4.5 kg of mortadella, which is three and a half logs or ten 450 g trays. The log lowers the cost per kilo but needs a machine and daily cleaning; the tray removes labour but costs more per kilo.
What belongs in a canteen's mortadella document file?
The file answers parents and inspectors at the same time and holds five items:
- A photocopy of the product label: name of the food, ingredients, allergens, net quantity, date, storage conditions, business registration number, origin and nutrition declaration. Those nine items are listed in Article 9 of the Turkish Food Labelling and Consumer Information Regulation, published in the Official Gazette (yeni sekmede açılır).
- The supplier's business registration number and a written product declaration: that the product is made from chicken and contains no pork.
- The halal certificate request and its answer: the certificate is requested from the supplier in writing, and the issuing body is checked on the Halal Accreditation Agency website (yeni sekmede açılır). If there is no certificate, the file notes "requested, pending" and the word halal is not used.
- The cold-chain log: delivery temperature, refrigerator temperature, name of the person receiving.
- The portion form: slice count, grams at first weighing, lot number.
The file lives in the canteen, not in an office. When a parent or the school management asks, it has to be on the table within five minutes.
How is a daily consumption plan for vegetable chicken mortadella set up in the canteen refrigerator?
The plan rests on one rule: an opened pack is finished the same day. In a sliced tray both faces of every slice are exposed to air, so a 450 g tray opened in the morning becomes sandwiches by the afternoon, or the remainder waits in a sealed container in the refrigerator and is the first thing used the next morning. On the log only the cut face is exposed; it is wrapped in film in the evening and stored between 0 °C and +4 °C.
The daily sandwich count is known in the morning because the school roll is fixed. Trays are opened to match: for 150 sandwiches, not ten trays at once but eight first, and two more after break if needed. A sealed tray has a 90-day shelf life, so a weekly order sits comfortably inside it and a spare tray does not become waste. The refrigerator thermometer is read in the morning and in the afternoon and written in the log.
Comparison table: mortadella and chicken jambon for a school canteen
| Per 100 g / criterion | Chicken Mortadella with Vegetables (1350 g log and 200/450 g tray) | Sliced Chicken Jambon (100/200/450 g) |
|---|---|---|
| Salt | 1.5 g | 2.5 g |
| Protein | 17.9 g | 20.6 g |
| Fat | 6.7 g | 2.8 g |
| Energy | 144 kcal | 120 kcal |
| Cross-section | Green and orange vegetable pieces, recognisable | Homogeneous, plain |
| Shelf life (sliced, sealed) | 90 days | 120 days |
| Salt in two slices (30 g assumption) | Roughly 0.45 g | Roughly 0.75 g |
| Canteen role | Salt-sensitive daily sandwich | Protein-led rotation day |
The last row of the table writes the decision: mortadella is the backbone of the daily sandwich, jambon takes two days a week. Rotating the two also closes the "same product every day" complaint from parents. Choosing snacks suited to school canteens uses the same criteria for the items beyond the sandwich. On the public-health side, the WHO food safety fact sheet (yeni sekmede açılır) notes that children are among the groups most vulnerable to foodborne illness, which is the reason the cold-chain log in the file is not optional.
How is mortadella sandwich preparation speeded up for the canteen break?
Break lasts fifteen minutes and the queue does not wait; preparation finishes before it starts. Sandwiches are made during the first lesson, labelled with their production time and arranged in a refrigerated display held between 0 °C and +4 °C. The slices go in folded: two folded slices make the sandwich look full and stay whole in the bite. If the log is used, slicing is done once in the morning, the slices are laid side by side on a tray and the tray goes into the refrigerator.
The second thing that shortens preparation is a standard recipe: two slices of mortadella, one slice of cheese, tomato, lettuce. Because the recipe never changes, every sandwich takes the same time and the portion does not drift. Whatever is left at the end of the day is discarded, and the leftover count corrects the next morning's preparation number.
The weekly quantity in a school canteen mortadella order
The weekly order is derived from the daily sandwich count: 150 sandwiches × 2 slices × 5 days = 1500 slices, or 22.5 kg at a 15 g assumption, which is roughly 17 logs or 50 trays of 450 g. A canteen choosing the log plans its machine and cleaning schedule accordingly; a canteen choosing trays plans its refrigerator shelf space. The five items of the file are requested from the supplier before the order; for samples, documents and a trade account, contact EMKA FOOD.
