Tetra Pak Study Shows Pasteurization Process Reduces the Levels of Vitamin C

Tetra Pak has released the most recent edition of its Orange Book with a study, which indicates pasteurization has little impact on the levels of vitamin C in orange juice. Approximately 70 million tons of oranges are produced around the world. About 33% of the aggregate tonnage is processed, the rest being consumed as fresh fruit. Tetra pack claims on average, the pasteurization process reduces the amount of vitamin C by less than 2%.

Maria Nolin, sub-classification chief, juice, Nectars and Still Drinks, Tetra Pak said, “Juice remains a significant part of the average consume diet around the world. Our examinations indicate pasteurization causes minimal effect on vitamin C retention while securing a safer product with a longer shelf life of the consumer.

We hope this (research) gives customers the evidence they have to communicate the nutritional values of the orange juice with consumers.” The tetra pak Orange Book covers the entire orange juice production chain, from quality control of the fruits to regional consumer insights.

Florida and Brazil are the world’s largest juice-producing countries. Here, the larger part of fruit harvested is processed because the orange varieties in the areas are gown for processing rather than for direct consumption. Together these regions represent around 80% of worldwide orange juice production.

Where possible, growers want to sell oranges to the fresh fruit market as their cost is regularly higher than for fruit sold for processing into juice. In a few countries, this can lead a significant variation in the amount of fruit processed starting with one year then onto the next.

The report states, ‘Because of the planting of new trees, world orange production continued to increase into the early 2000s mainly in Florida, Brazil, and China. Orange production is likewise expected to increase further in different regions as a result of improved planting programmes, cultivation technique, and support to orange growers.

Nevertheless, unwanted climatic impacts frost and storms, alongside uncontrolled fruit tree diseases, could decrease crop and juice yield altogether. Recent years have seen notable changes in world orange production and since 2010 the worldwide harvest has declined because of unfavorable climate and infections in major production areas’.


As per tetra pak, China has seen the fastest development in citrus fruit production thought the intensive planting of trees and is today the world’s largest producer. Mandarins make up most of the citrus crop. Most oranges in China are consumed fresh, with just a small amount of fruit being processed. The Mediterranean is an important area for growing high-quality fruit. As more Mediterranean oranges are being eaten fresh, juice production is gradually declining in this region, except for Spain.

The Orange process can be divided into two groups:

  • Marketing processors
  • Bulk processors

Marketing processors sell packed juice under their own brand name, which requires retail and consumer marketing skills.

Bulk processors mainly sell their products in bulk form, which requires skills in the efficient distribution and marketing of a commodity.

The biggest marketing processors have based Florida and include Tropicana (part of PepsiCo group), and Citrus World. These companies process fruit and fill it into retail packages at their own facilities. They likewise purchase additional juice in bulk from other bulk processors.

For marketing processors, control of product availability is viewed as more important than ownership for resources. For instance, Coca-Cola now concentrates on marketing and distributing Minute-Maid and Simply orange brands: Brazilian Company Cutrale possesses and operates the juice production facilities.

Bulk processors produce the majority of orange juice around the world. Bulk delivery is the need for the large Brazilian processors. They don’t have their own consumer brands, partly to avoid competing with their bulk juice customers.

The report states the most recent decade has seen major changes in Brazil’s orange juice industry, with a reduction in the major players from five to three.
