Fruit juice freshness that lasts, profits that grow. This post will teach you of the preservatives relevant to prolonging the shelf-life of your fruit juices for commercial sale.
Commercial sale implies that you are producing for public sale and consumption; whether a few bottles from your home or in larger batches of hundreds to stock in supermarkets.
It is important to ensure hygienic preparation methods, clean and sterilized utensils; proper handling, storage, and distribution procedures to affirm juice quality and safety. Without these safe preparation procedures, implementing preservatives is just a waste of time.
Preservatives play a crucial role in extending the shelf life of juices for commercial sale because they ensure the safety, quality, and longevity while also supporting business operations and regulatory compliance.
Regardless of the useful information on fruit juice preservatives you learn here, it is essential and recommended to consult with a food technologist or a regulatory expert to confirm information about your fruit juice production and the preservatives that you intend using or that are ideal to ensure compliance with local regulations, to confidently determine the optimal preservative levels for your specific product or a COMBINATION OF PRESERVATIVES FOR OPTIMAL RESULTS.
Fruit juice preservatives are often used in combination with each other to achieve optimal preservation and shelf-life.
1. Synergistic effects: Combining preservatives thereby creating effects that the total preservative effect is greater than the sum of individual preservatives.
2. Broad-spectrum protection: Using multiple preservatives can provide broad-spectrum protection against various microorganisms, enzymes, and oxidation reactions.
3. Reduced usage levels: Combining preservatives can allow for reduced usage levels, minimizing potential impacts on flavor, aroma, and nutritional content.
4. Enhanced shelf-life: Combining preservatives can help extend shelf life by controlling multiple spoilage mechanisms.
Commonly used preservatives in juice production and their required quantity:
N.B: Combination preservatives and their ratio quantities will be discussed after this section.
■ Sodium Benzoate: A widely used preservative that inhibits the growth of mold, yeast, and bacteria. The recommended dosage is 0.08% to 0.1% of the total volume.
It is very efficient under acidic conditions. Therefore, Sodium Benzoate is effective to prevent the contamination of bottled juices like apple or lemon juice.
■ Potassium Sorbate: Effective against mold and yeast, this preservative is commonly used in combination with other preservatives. The recommended dosage is 0.1% to 0.2% of the total volume.
Potassium Sorbate, an acidic preservative used in apple or lemon juices prevents the product from fermentation and keeping the taste as fresh as possible.
■ Sorbic Acid: A natural preservative that inhibits the growth of mold and yeast. The recommended dosage is 0.1% to 0.2% of the total volume.
Sorbic acid is recommended for concentrated juices except for frozen concentrated orange juice.
■ Citric Acid: A natural preservative that helps maintain the pH balance in juices, inhibiting the growth of microorganisms. The recommended dosage is 0.5% to 1% of the total volume.
A preservative as well as an additive to enrich the flavor and maintain the color of juice made of citrus fruits and berries. An acidity regulator in processed juice, fruits and vegetables.
■ Ascorbic Acid (Vitamin C): An antioxidant that helps preserve the color and flavor of juices. The recommended dosage is 0.1% to 0.2% of the total volume.
Ascorbic acid is used in fruit juices, fruit-flavored drinks, sodas, and powdered beverage mixes.
Below is an estimate of the quantity of preservatives added to different volumes of juice:
■■ 500ml juice:
- Sodium Benzoate: 0.4-0.5g
- Potassium Sorbate: 0.5-1g
- Sorbic Acid: 0.5-1g
- Citric Acid: 2.5-5g
- Ascorbic Acid: 0.5-1g
■■ 1 liter juice:
- Sodium Benzoate: 0.8-1g
- Potassium Sorbate: 1-2g
- Sorbic Acid: 1-2g
- Citric Acid: 5-10g
- Ascorbic Acid: 1-2g
■■ 5 liter juice:
- Sodium Benzoate: 4-5g
- Potassium Sorbate: 5-10g
- Sorbic Acid: 5-10g
- Citric Acid: 25-50g
- Ascorbic Acid: 5-10g
Here are the quantities of combination preservatives in grams for different volumes of juice:
■■ Sodium Benzoate (0.05-0.1%) + Potassium Sorbate (0.1-0.2%): Effective against mold, yeast, and bacteria.
5-500● 500ml juice: 2.5-5g (Sodium Benzoate: 0.25-0.5g, Potassium Sorbate: 2.25-4.5g)
● 1 Liter Juice: 5-10g (Sodium Benzoate: 0.5-1g, Potassium Sorbate: 4.5-9g)
● 5 Liter Juice: 25-50g (Sodium Benzoate: 2.5-5g, Potassium Sorbate: 22.5-45g)
● - ● 10 Liter Juice: 50-100g (Sodium Benzoate: 5-10g, Potassium Sorbate: 45-90g)
■■ Sorbic Acid (0.1-0.2%) + Citric Acid (0.5-1%): Provides antioxidant and antimicrobial protection.
●●● 500ml Juice: 5-10g (Sorbic Acid: 0.5-1g, Citric Acid: 4.5-9g)
- ● 1 Liter Juice: 10-20g (Sorbic Acid: 1-2g, Citric Acid: 9-18g)
- ● 5 Liter Juice: 50-100g (Sorbic Acid: 5-10g, Citric Acid: 45-90g)
● 10 Liter Juice: 100-200g (Sorbic Acid: 10-20g, Citric Acid: 90-180g)
■■ Ascorbic Acid (Vitamin C) (0.05-0.1%) + Tocopherol (Vitamin E) (0.01-0.05%): Antioxidant combination to prevent oxidative reactions.
- ● 500ml Juice: 2.5-5g (Ascorbic Acid: 0.25-0.5g, Tocopherol: 2.25-4.5g)
- ● 1 Liter Juice: 5-10g (Ascorbic Acid: 0.5-1g, Tocopherol: 4.5-9g)
- ● 5 Liter Juice: 25-50g (Ascorbic Acid: 2.5-5g, Tocopherol: 22.5-45g)
● 10 Liter Juice: 50-100g (Ascorbic Acid: 5-10g, Tocopherol: 45-90g)
