Description

Lactobacillus casei is a well-characterized probiotic bacterium widely utilized for its beneficial effects on gut health and food fermentation. This specific strain, identified by CAS No. 68333-14-2, is valued for its stability, survivability, and ability to positively modulate the intestinal microbiota. It is a critical ingredient for manufacturers in the functional food, dietary supplement, and pharmaceutical industries seeking to develop products that support digestive wellness and immune function.

Application

• Probiotic Dietary Supplements: Used in capsules, tablets, and powder formulations to deliver live, active cultures for gut health support.
• Functional Food & Beverages: Incorporated into yogurts, fermented drinks, dairy products, and health bars to enhance probiotic content.
• Pharmaceutical Preparations: Employed in the development of specialized probiotic drugs and medical nutrition products.
• Animal Feed & Nutrition: Applied as a direct-fed microbial to promote growth performance and gut health in livestock and poultry.
• Starter Cultures: Used in the fermentation process for various artisanal and industrial food products.
• Cosmeceuticals: Explored for use in topical skincare formulations for its potential skin microbiome benefits.

Quality Control

Our Lactobacillus casei is produced under strict quality management systems to ensure viability, purity, and identity. Each batch is tested for microbial enumeration (CFU/g), strain identification, and the absence of specified contaminants. Certificates of Analysis (COA) detailing purity, potency, and safety are available upon request. Production can adhere to relevant standards for food-grade (FCC) and pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. This product is hygroscopic (moisture-sensitive) and should be stored in a cool, dry place. For long-term stability, storage at 2-8°C (refrigerated) is recommended. Keep the container sealed under controlled humidity conditions to maintain viability and prevent moisture absorption.
