![]() | ![]() | III. THE DIFFERENT TYPES OF PACKAGING |
By combining the different stabilisation and packaging processes, it is possible to classify the different types of packaging as follows:
A. Pasteurisation and cold packaging/filling (short shelf-life)
B. Pasteurisation and cold packaging with chemical preservatives(long shelf-life)
C. Pasteurisation with hot packaging/filling, and eventual post-pasteurising (long shelf-life)
D. UHT or HTST treatment with sterilised packaging (long shelf-life)

the following table

Packaging* |
Discussion |
A |
2 to 4 weeks in cold storage (+4°C to +6°C) |
(1) HDPE bottle |
Immediately after fresh fruit juice extraction, juice is pasteurised at 80/95°C for a few seconds then cooled to +4°C and stored in an insulated tank before packaging |
B |
1 month to several months according to the level of anti-oxygen barrier |
(6) LDPE pouch < 200 ml |
Chemical preservatives are less and less acceptable to consumers |
C |
More than 3 months at room temperature |
(9) Thermoformed cup 100 ml to 300 ml |
- Only for acid products (pH less than 4.5) |
D |
More than 6 months at room temperature |
(16) Brick |
- Undeniable advantage linked to the quality of the end-product:
no chemical preservative, natural taste thanks to the very short heat
treatment |
*numbers correspond to the appropriate technical filing-card
For each process, investment budgets vary from 1 to 20 for identical capacities. It is therefore important to understand the operations limits of each process.
Definition:
Products with a shelf-life of 2 to 4 weeks which must be stored in a cold chain (temperature less than +7°C); this process is used for natural fruit juices.
This type of product has shown a marked development in Europe in recent years because of increased consumer demand for natural products.
Principle:
Most juices on the market are obtained from the extraction of pulp from fresh fruit which is then pasteurised (at temperatures between 80 and 95°C for 2 to 3 seconds) and then cooled at +4°C ("flash" refrigeration) for packaging.
A refrigerated distribution network (less than 7°C) must be used, and the shelf-life is limited to 2 to 4 weeks only. Shorter periods can be indicated in order to stimulate product sales (8 days as in the case of pasteurised milk).
Advantages:
Excellent natural tasting product, closest to fresh fruit juice
Possibility of low capacity processing plant (less than 1 000 litres per day)
Initial investment in machinery adapted to small projects with low output
Disadvantages:
Refrigerated distribution network often non-existent in Africa (to be created)
Initial investment to be made in a cold room and a refrigerated vehicle
Obligation to work with fresh fruit imposes seasonal production schedule

N° 5: the Gable-Top Carton
Box
Definition:
These products can be kept at room temperature for several months thanks to the presence of chemical preservatives. Most of these products are mainly fruit drinks with addition of sugar and water.
Principle:
This type of treatment is mainly used for fruit drinks with a greater degree of dilution; the pH being often greater than 5, it is necessary to decrease it to less than 4.2. The preservative is usually added before pasteurisation and processing is carried out at low temperature. The preservatives are selected on the basis of two criteria:
· The prevention of the development of bacteria, mould or yeasts in the product.
· The prevention of the effects of oxidation on the product.
Advantages:
· Simple technology and installation
· Possibility of packaging for low output production (reduced initial investment)
· Possibility to choose cost-effective packaging materials (PE bag)
· Product can be stored at room temperature
Disadvantage:
· Use of chemical additives (see annex 3)

N° 8: PET
Bottle
Definition:
These products are natural, with the shelf-life obtained only by heat treatment; they can be kept several months at room temperature.
Principle:
Heat-treated packaging, at temperatures between 80 and 95°C, is the oldest technique for preserving fruit juices and drinks with a pH of less than 4.5. The double effect of the heat (destruction of bacteria, mould, yeasts and enzymes) and the acidity results in preservation of the product. The previously pasteurised juice disinfects and sterilises its own packaging simply from its temperature.
For security reasons, post-pasteurisation of the product and its packaging is also recommended (at more than 80°C for several minutes). For capacities of over 2000 units per hour, post-pasteurising tunnels are also equipped with a continuous cooling section.
Advantages:
Possibility of working at a low production rate (from 200 units per hour) with a moderate initial investment (less than £ 37,500) for the combined pasteuriser-packaging machine).
Long shelf-life products
No chemical preservatives
Disadvantage:
Packaging and contents must be rapidly cooled to avoid the development of a cooked taste.
Note: Plastic bottles are not mentioned in this chapter on heat-treatment packaging. Research is currently being carried out on new compounds and new technologies capable of resisting heat without deformation while at the same time remaining impermeable to oxygen. The Sidel company has perfected a system which allows for the production of PET which is adapted to filling during heat treatment (thermofixation). A new polymer, PEN (polyethylene naphtalate)(9), when combined with PET also improves resistance. These new processes or products have not been presented in this manual because their cost is still prohibitive for the target markets. Their development should however be monitored in order to include them in future packaging selections.

N° 15: Metallic
Cup
Definition:
Sterilised packaging treatment was developed by Tetrapak in the mid-1960s for the preservation of milk (140°C in 5 seconds).
For reasons of quality, this process has been adopted by practically the entire milk industry and is now being considered by manufacturers of fruit juices. In effect, the product is heated for a very short time - less than a minute - compared to the long heating treatment for the hot filling system. The shelf-life is also several months at room temperature.
Remark: For acidic products (pH < 4.5), a heat treatment at 90/95°C during a few seconds is enough (HTST), but for products with a higher pH (pH > 4.5) a UHT treatment is necessary.
Principle:
The product (juice) is treated at a high temperature (from 95 to 140°C) for several seconds in order to destroy bacteria, yeasts and mould, and to deactivate the enzymes responsible for undesirable reactions during storage. After rapid cooling at 20/30°C, the treated product is packaged. The packaging machine must therefore include a special section in which all the procedures of filling and closing the packaging are executed in an environment free of bacteria and any other contaminants. The packaging itself must be disinfected to ensure that it is also free of any contamination (oxygen peroxide, ultraviolet, hot air, etc.).
To avoid all risk of contamination (a single bacteria can corrupt the package), sophisticated techniques must be adopted (automation, integrated cleansing, etc...) which requires production rates of at least 4000 units per hour.
Advantages:
· Improved preservation of natural taste due to the short sterilising treatment and subsequent rapid cooling.· A completely natural product without chemical preservatives.
· The possibility of using packaging materials other than glass or metal, i.e. compound cardboard and multi-layer plastics.
Disadvantages:
· High investment costs (more than £ 625,000 for the combined UHT steriliser/aseptic packaging machine).· High production rates.
· Sophisticated technology necessitates a highly trained labour force (production and maintenance).
· Steril working conditions at the packaging level.
