IntroductionA food service system is defined as an
entity composed of several systems designed and functioning together to accomplish specific objectives
Simple definition- “Provision of food and drink ready for consumption away from home”
![Page 4: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/4.jpg)
AdvantagesEntire food service is “one body” and several subsystems work together for the system to functionEmployees and management work together as a teamProblems are easily locatedCost control and budgeting can be facilitatedMultiple chain-type operations is easier to plan and evaluateTraining programs can be developed for knowing each members performanceEasier to control and monitor activities within the systems
![Page 5: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/5.jpg)
Categories of Food Service SystemThe systems differ in “Where the food is
prepared” in relation to “where it is served”, the “time span” between preparation and service, the forms of foods purchased, methods of holding prepared foods and “the amount and kind of labor and equipment required”It is classified into 4 types:1. Conventional service2. Ready – prepared service3. Commissary4. Assembly/ Serve
![Page 6: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/6.jpg)
I. Conventional/ Traditional Food Service
Traditionally usedMenu items are prepared in kitchen and held for short time until serving timeEarlier, it was prepared in the premises hence kitchen included a butcher shop, bakery and vegetable preparation units
![Page 7: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/7.jpg)
Gradually the modified conventional system has evolved where foods with varying degrees of processing are used, hence customers food is prepared on same siteTypically used by smaller food service operations
![Page 8: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/8.jpg)
Usually found in restaurants:
Call order/ À la carte
Table d'hôte system
![Page 9: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/9.jpg)
In a health care facility, the patient service is a complex distribution process and involves:
1. Centralized meal assemblyTime between production, assembly and distribution is minimalTrays are assembled at a central locationTrays are distributed to patient units using carts(heated/ refrigerated)
Advantages:Activity takes place in one locationAllows standardization of portionUniformity in presentationWaste reductionLess time of staff
![Page 10: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/10.jpg)
2. Decentralized meal assembly
Foods are produced in one location and transported to various locations for assembly at sites near patientsEquipment to maintain proper temp. is provided at each locationTo difficult-to-hold foods, cooking equipment is available in service units
Advantages:Less time neededGroup services are easy
![Page 11: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/11.jpg)
AdvantagesQuality control is consideredAchievement of individuality and standard of quality is desiredNot dependent on availability of frozen entréesMore adaptable to regional, ethnic and individual preferenceGreater economic flexibility Less freezer storage space and distribution costs
![Page 12: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/12.jpg)
DisadvantagesConventional system produces an uneven, stressful dayWorkloads vary depending on change of menuSkilled workers are supplemented by non-skilled workers2 shifts of employees are required Scheduling of workers are difficult
![Page 13: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/13.jpg)
II. Ready – prepared food service system
Menu items are produced and held for servicePacked in bulk, in individual portions or combination containersIts distinct feature is the separation between time of preparation and serviceFood is not for immediate useFoods are prepared on site, however place of preparation is not place of serviceAdopted by in-flight caterers
![Page 14: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/14.jpg)
Distribution equipment needed by ready prepared operations depends on whether foods are in bulk quantities or individual portions and have 3 main technologies mainly:Cook – chill processCook – freeze processSous-vide (vacuum packing)
![Page 15: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/15.jpg)
(i) Cook – chill processAcc. To Cusins.J.et.al, “It is a catering
system based on normal preparations and cooking of food followed by rapid chilling, storage in control of low temp. above freezing point and subsequently reheating before consumption”
![Page 16: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/16.jpg)
Cook - chill processChilled down for final storage (3˚C)(90 mins)
Can be achieved by blast chilling–Blast chillers use conventional refrigeration
techniques (cold air circulation) or cryogenic methods (use of gases to reduce temp.)
Stored for 5 days When not in chilled storage, all handling is carried out
in environmental room For consumption, food is heated 2hrs at 70˚C 10 ˚C- critical safety limit for chilled foods During distribution, if temp. exceeds 5˚C food has to be
consumed within half hrs
![Page 17: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/17.jpg)
Advantages:• Can be applied to most food stuffs• Can be applied to both individual meal or bulk-meal
production• There is no apparent effect on meal palatability after 3
days although some meat dishes may deteriorate after 4-5 days
Disadvantages:• Additional investment required to meet new standards• Critical and narrow temp. requires high operational
standards• Nutrient and vitamin loss occurs during chilled storage
![Page 18: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/18.jpg)
(ii) Cook Freeze MethodSpecialized food production and distribution system that allows caters to take advantage of longer life thru’ blast freezers (-18 to -20 ˚C) and store up to 3 - 6 months Blast freezer or cryogenic freezers are required for this purposeIt follows the below steps:PreparationFreezing (blast freezer)Storage (deep freezer -18 ˚C)Transport of frozen itemsRegeneration (convection ovens)
![Page 19: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/19.jpg)
Advantages:Maximum shelf life of 3 monthsEasily handled in frozen state without any spoilageGreater flexibility in use
Disadvantages:Not all dishes can be frozenRecipes may require modificationsLow temp. storage requires greater energy use
![Page 20: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/20.jpg)
(iii) Sous – vide (vacuum cooking)
Most recent and innovative approach for dish preservationIncludes vacuum packing of foods in plastic bags that can be raw or semi-cooked Chilled storage is required and shelf life is extended to 21 days hence suited to individual mealsRequires more investment and timeUsed in restaurants and not used in large-scale
![Page 21: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/21.jpg)
Advantages:Long shelf lifeMeals are produced in advanceCan be mixed with cold storage without risk in
contaminationReduce labor costTexture and flavor is retained Inexpensive regeneration
Disadvantages:Extra cost requiredAll portions in one batch must be identicalCooking time is more
![Page 22: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/22.jpg)
Advantages:Reduces the “peak and valleys” of workloadsProduction labor cost is reduced Improved quality and quantity controlLack of worry about deliveryDisadvantages:Need for large cold storage and freezer unitsBlast chiller or blast freezer is required
which is expensiveControl of food safety is essentialExtensive changes in recipe is required
![Page 23: Types and categories of food service system..](https://reader033.fdocuments.in/reader033/viewer/2022052606/587a13fd1a28abb4238b4e0d/html5/thumbnails/23.jpg)
