Project Description
Product Description
Lactobacillus plantarum is a kind of lactic acid bacteria, the optimum growth temperature is 30~35, anaerobic or facultative anaerobic, the strains are straight or curved rods, single, sometimes in pairs or chains, the optimum pH is 6 . 5 or so, belonging to the same type of fermenting lactic acid bacteria. This bacteria has a relatively high number of viable bacteria, which can produce a large amount of acid, so that the pH value of the water is stable and does not increase, and the acidic substance it produces can degrade heavy metals; because this bacteria is an anaerobic bacteria, facultative and aerobic, it is reproducing The unique lactobacillus can be produced in the process, which is a biological preservative.

Applications & Recommended Usage
Lactobacillus plantarum is a versatile probiotic strain used across multiple application sectors, valued for its well-documented functional properties and adaptability to different formulation types. The following outlines its main application areas and recommended usage levels.
- Dietary Supplements
In the dietary supplement sector, Lactobacillus plantarum is commonly used in capsules, tablets, and powder sachets for digestive and immune health formulations. The recommended dosage is typically between 1.0 × 10⁹ and 1.0 × 10¹⁰ CFU per serving. It is often combined with other probiotic strains, prebiotic fibers, or vitamins to create comprehensive gut health blends. Its fine powder consistency allows for easy blending with other supplement ingredients and is suitable for standard encapsulation and tableting processes.
- Functional Foods
In functional foods, Lactobacillus plantarum is used to enrich products such as yogurts, fermented drinks, and health bars with probiotic cultures. The recommended dosage is typically between 1.0 × 10⁸ and 1.0 × 10⁹ CFU per serving. The strain is stable in fermented dairy products and can be incorporated during the fermentation process. For non-fermented foods, we recommend post-fermentation addition to maintain viability. It is compatible with a wide range of food matrices and does not significantly affect the taste or texture of the final product.
- Beverages
In beverage applications, Lactobacillus plantarum is used in ready-to-drink (RTD) functional drinks, fermented juices, and kombucha-type products. The recommended dosage is typically between 1.0 × 10⁸ and 1.0 × 10⁹ CFU per serving. The strain exhibits good stability in both dairy and non-dairy liquid systems, including fruit-based and plant-based beverages. For beverage applications, we recommend small-scale trials to confirm stability under the specific pH, temperature, and shelf-life conditions of the target product. For fermented beverages, the strain can be used as a starter culture to drive the fermentation process.
- Animal Nutrition
In animal nutrition, Lactobacillus plantarum is used in feed additives, chews, and powders for companion animals and livestock. Recommended usage levels vary by animal species and product type and should be determined in accordance with veterinary or nutritional guidelines.
Storage & Stability
Proper storage is essential to maintain the viability and efficacy of Lactobacillus plantarum throughout its shelf life. The following guidelines are designed to support procurement and formulation decisions.
- Refrigerated Storage (2 – 8°C)
This is the recommended storage condition for long-term preservation. When stored at 2 to 8 degrees Celsius, the product maintains a minimum of 80% viability for up to 24 months from the date of manufacture. This condition is ideal for maintaining high viable cell counts and ensuring consistent potency in finished products.
- Ambient Storage (≤ 25°C)
For short-term storage or products intended for ambient distribution, the strain may be stored at temperatures up to 25 degrees Celsius. However, viability will gradually decline over time under these conditions. Specific stability data for ambient storage is available upon request. We recommend conducting stability trials under the specific storage and distribution conditions of the target market to confirm shelf life and viability retention for ambient-stable formulations.
