What is unpasteurized juice?
Unpasteurized juice, often referred to as “raw” or “fresh-squeezed” juice, is juice that has not undergone pasteurization. Pasteurization is a process that uses heat to kill harmful bacteria and extend the shelf life of the juice. Since unpasteurized juice skips this step, it retains more of its natural flavors, enzymes, vitamins, and minerals.
However, if unpasteurized juice is manufactured in facilities that are not FDA certified, or have no food safety certification, it can pose health risks due to potential contamitants and pathogens. It’s recommended to consume unpasteurized juice from credible, food-safety certified vendors within a few days and keep it refrigerated. The FDA advises that certain groups, such as pregnant women and young children, avoid unpasteurized juices due to these potential risks.
What is pasteurized juice?
Pasteurized juice is juice that has been heated to a specific temperature to kill harmful bacteria and pathogens. This process, known as pasteurization, helps to extend the shelf life of the juice and make it safer to consume.
The main benefits of pasteurized juice include:
- Reduces the risk of foodborne illnesses by eliminating harmful microorganisms.
- Extends the juice’s shelf life, allowing it to be stored for longer periods without spoiling.
- Available in a variety of packaging options and can be stored at room temperature until opened.
Pasteurized juices are shelf-stable products sold in supermarkets
There are several methods to pasteurize juice, each with its own advantages.
Heat pasteurization
Heat pasteurization is a method used to kill harmful microorganisms in food and beverages, extending their shelf life and ensuring safety. The most common pasteurization methods include:
- High-Temperature Short-Time (HTST) Pasteurization, also known as flash pasteurization, heats the product to at least 161°F (72°C) for 15-20 seconds. This method effectively kills pathogens while preserving the flavor, color, and nutritional value of the product. It is commonly used for milk, fruit juices, beer, and some dairy products.
- Ultra-High Temperature (UHT) Pasteurization, also known as ultra-pasteurization, heats the product to at least 275°F (135°C) for 2-5 seconds. It is commonly used for milk, cream, fruit juices, soy milk, yogurt, etc. This method extends the shelf life of products significantly, allowing them to be stored without refrigeration until opened.

Cold pasteurization
Cold pasteurization, also known as High-Pressure Processing (HPP), is a non-thermal method used to preserve and sterilize food and beverages. The product is subjected to extremely high pressure (up to 87,000 psi) using only filtered water. It is commonly used for juices, dairy products, etc.
This method helps to maintain the original flavor, texture, and nutritional value of the product; increases the shelf life without the need for preservatives; and effectively destroys harmful bacteria and pathogens.
Cold pasteurization is particularly beneficial for heat-sensitive products, ensuring they remain fresh and safe to consume.
Is unpasteurized juice healthier than pasteurized juice?
Several factors determine whether pasteurized vs unpasteurized juice is better for your health. Some important things to keep in mind are:
| Unpasteurized Juice | Pasteurized Juice |
| Nutrient Content: Unpasteurized juice often retains more of its natural vitamins, enzymes, and antioxidants because it hasn’t been exposed to heat. | Nutrient Loss: Some heat-sensitive nutrients, such as vitamin C and certain enzymes, may be destroyed during pasteurization. |
| Flavor: unpasteurized juice has a fresher, more vibrant taste. | Added Flavor: Pasteurization can sometimes lead to a slight loss of flavor. To compensate for this, manufacturers might add natural or artificial flavors, , and other additives to enhance the taste. |
| Risks: Juice processed in unsafe facilities may sometimes be contaminated. Unpasteurized juice must be processed in food safety certified facilities. | Safety: Pasteurization kills harmful bacteria, making the juice safer to drink. |
| Shelf Life: Unpasteurized juice should always be kept refrigerated. When stored properly, it typically stays fresh for about 2 to 3 days. | Shelf Life: Pasteurized juice has a longer shelf life and can be stored for extended periods without spoiling. |
Therefore, if safety is a primary concern, especially for vulnerable individuals, pasteurized juice is generally the better option. However, if you prioritize nutrient content and are confident in the cleanliness of the source, unpasteurized juice can be a good choice.
How to distinguish between pasteurized and unpasteurized juice?
Knowing what to look for makes it easy to distinguish pasteurized juice from unpasteurized juice. Here are some tips:
First, search for Labels and Packaging. Unpasteurized juices frequently have a warning sign indicating that the product has not been pasteurized and may contain hazardous microorganisms.
Pasteurized juices typically have a longer shelf life and can be found in non-refrigerated sections, while unpasteurized juices are usually found in the refrigerated section and have a shorter shelf life.

Second, examine their Appearance and Taste. Unpasteurized juices may appear cloudier and include more sediment than pasteurized juices, which are often clearer due to the removal of certain particles during pasteurization.
Unpasteurized juices typically have a fresher, more vibrant flavor, whereas pasteurized juices may taste slightly cooked or less fresh due to the heating process.
Third, consider the Purchase Location. Unpasteurized juices are more easily accessible at farmers’ markets, health food stores, refrigerated sections at supermarkets, and cider mills, whereas pasteurized juices are generally available in supermarkets.
By checking these indicators, you can readily identify whether a juice is pasteurized or not.
Is drinking unpasteurized juice dangerous?
Generally, unpasteurized juice made in clean and food safe conditions are safe to consume. These may be food-safety inspected café and restaurants or just in your clean kitchen.
However, unpasteurized juice produced in dirty environments can contain harmful bacteria such as E. coli, Salmonella, and Listeria, which can cause serious illness. Children, the elderly, pregnant women, and individuals with weakened immune systems are particularly at risk of severe illness from these bacteria.
Customers must always check the label for pasteurization information. Unpasteurized juices on supermarket shelves often have a warning label indicating they have not been pasteurized. After buying, ensure that unpasteurized juices are kept refrigerated and consumed within a short period to minimize the risk of bacterial growth.
While unpasteurized juice can offer a fresher taste and potentially more nutrients, the safety risks should be carefully considered, especially for immuno-compromised individuals. If safety is a primary concern, opting for pasteurized juice is generally the safer choice.

How to safely make unpasteurized juice at home?
Homemade unpasteurized juice is a healthy and tasty alternative, but it is crucial to follow safety precautions to avoid contamination.
Step 1. Choose Fresh, High-Quality Produce
Select fruits that are fresh and free from bruises or damage. Organic products are often preferred to reduce exposure to pesticides. If the fruit develops an off smell, taste, or appearance, discard it immediately.
Step 2. Wash Thoroughly
Wash your hands with soap and water before handling the fruit. Rinse fruits under running water, then soak them in warm salt water or veggie wash to remove dirt and bacteria.
Step 3: Sanitize Equipment
Make sure you clean and sanitize all of your juicer tools, including knives, cutting boards, and juicers.
Keep raw produce separate from other foods, especially raw meat, to prevent cross-contamination.
Step 4: Prepare the Produce
Peel and core fruits if necessary, and cut them into pieces that fit your juicer. Remove any seeds or pits that could affect the taste or texture of the juice.
Step 5: Juicing
Juice the fruits using a clean juicer. Transfer the juice to a sterilized container. If you are concerned about safety, you can lightly heat the juice to 160°F (71°C) for a few seconds to kill most harmful bacteria while retaining much of the fresh taste.
Step 6: Storage
Put the juice in an airtight container and put it in the fridge right away to keep the juice fresh and prevent bacteria from growing, and drink it within 24-48 hours.
By following these steps, you can enjoy fresh, unpasteurized juice while minimizing health risks.
Conclusion
The ongoing debate between pasteurized vs. unpasteurized juice revolves around the balance between food safety and nutritional value. There is a higher danger of infection with unpasteurized juice, but it has a fresher taste and more nutrients. While some nutrients may be lost during pasteurization, pasteurized juice offers a safer alternative with a longer shelf life.
In the end, your decision is determined by the priorities that you have, whether you place a higher value on convenience and safety or whether you choose the natural and raw aspects of unpasteurized juice.
