Interesting facts about tinned fruit

Tinned fruit, also known as preserved fruit, is an industrially processed foodstuff that offers a practical and long-lasting alternative to many types of fresh fruit. It is characterised, for example, by its high level of microbial safety and storage stability, as well as its ease of handling in logistics. This blog article examines aspects relating to its production, nutritional content and a number of other factors.

From fresh fruit to tinned fruit

Canned fruit is produced through a multi-stage process designed to ensure safe and long-lasting products. When selecting suitable fruit, factors such as the stability of flavour, colour and texture, as well as consistency, play a role. Pineapples, peaches, apricots, pears, cherries and mixed fruit blends are particularly common types of tinned fruit.

The manufacturing process generally consists of a highly standardised procedure and involves a number of steps – for example, the following:

• Harvesting and preparation

Harvesting the fruit at the optimum stage of ripeness is key to ensuring the highest possible nutrient content and the most intense flavour. If the fruit is then transported immediately to the nearest processing facility, any loss of quality due to long journey times can also be avoided.

• Quality control and cleaning

Once the goods have been checked for quality and any damage, they are thoroughly cleaned to remove dirt and other residues.

• Peeling, coring and cutting into portions

The removal of skins, cores or stones can be carried out mechanically, thermally – for example, using steam – or chemically. The fruit is then shaped evenly into the desired form. Ensuring that the pieces of fruit are of a uniform size is important both for filling and for the subsequent Food preservation important.

• Blanching

Brief heating is an optional step, but one that is frequently carried out for many types of fruit. It serves to remove microorganisms and deactivate enzymes that would otherwise alter the flavour or colour of the tinned fruit.

• Filling and sealing

When the fruit is placed in the tin, it is combined with a liquid – often a syrup or a less sugary water mixture. To create a vacuum, the tins are briefly heated before sealing or sealed under vacuum. The vacuum prevents oxidation and reduces the stress on the tin during sterilisation.

• Preservation and completion

To ensure food safety and a long shelf life, the tightly sealed tins are then heated to high temperatures for a precisely defined period of time and subsequently cooled rapidly. Sterilisation is the crucial step in ensuring the long shelf life of tinned fruit, as it kills off bacteria. The rapid cooling ensures that the texture and nutritional value of the contents are preserved as much as possible. Following final quality checks to ensure product safety and correct labelling, the tinned fruit is dispatched – packed in cartons or other suitable packaging solutions, it eventually finds its way onto the shelves in a wide variety of forms.

About the ingredients and nutrients in tinned fruit

The question keeps coming up as to whether tinned fruit is actually healthy. The multi-stage processing of the fruit into tinned fruit, as well as the sugar content – which is often quite noticeable on the palate – naturally raises doubts. Ultimately, it is worth taking a closer look at the issue to consider the various aspects involved in answering this question.

Due to the canning process and the heat treatment it involves, temperature-sensitive vitamins in particular can be lost in tinned fruit. However, there is also an advantage to tinned fruit: When harvested at the perfect time, they contain their optimal nutrient content – the subsequent canning process and the airtight seals on the tins slow down the breakdown of nutrients after harvest. Fresh fruit is subject to this loss throughout the entire period of transport and storage.

Although fresh fruit is generally regarded as the gold standard from a health perspective, the poor reputation of tinned fruit is not necessarily justified.

An important factor: the brewing liquid

The sugar content of tinned fruit is influenced, in particular, by the syrup in which it is preserved, compared with fresh fruit. If products are preserved in a syrup with a high sugar content, the sugar content is understandably much higher. This additional sugar intake can be counteracted by choosing products that are preserved in their own juice or with no added sugar.

Environmental aspects of tinned fruit

Under certain circumstances, tinned fruit can offer a favourable environmental footprint:

• Utilisation of surplus crops: Processing the fruit into tinned fruit can help to, Food waste to reduce waste. Surplus crops can be put to good use efficiently and preserved before they go off – and even fruit that does not meet visual standards can be successfully processed into tinned fruit.

• Independence of the season: Tinned fruit makes it possible to eat fruit that is not in season – without having to resort to energy-intensive greenhouse-grown produce or air freight.

• Transport and storage: Both of these factors go hand in hand with tinned food that does not require refrigeration, which represents a clear advantage over the refrigerated storage and transport of fresh fruit. Tins require less energy during the logistics process and can also be transported and stored in a space-saving manner.

Environmental benefits can be achieved in particular when fruit – which would otherwise be imported by air from overseas, a process that consumes significant resources – is harvested locally and processed into tinned fruit before being transported further.

Availability and convenience

The fact that it is not subject to seasonal variations is a clear advantage here. Furthermore, tinned fruit no longer requires any preparation such as peeling, washing or pitting. This makes it particularly attractive for commercial kitchens, bakeries and patisseries, as well as the food industry.
