Orange Serum Agar

Intended Use

Orange Serum Agar is specifically formulated for the cultivation of aciduric microorganisms linked to the spoilage of fruit juice products.

Product Summary and Explanation

The unique low pH of citrus fruit juices renders them particularly vulnerable to spoilage from yeasts, molds, and specific bacteria such as Lactobacillus and Leuconostoc. Back in the 1950s, significant research led by Hays focused on the spoilage phenomena observed in frozen concentrated orange juice. The findings revealed that an agar medium enriched with orange serum significantly outperformed Lindegren Agar when isolating microorganisms responsible for spoilage, particularly those that result in undesirable buttermilk off-odors.

Subsequent research conducted by Murdock, Folinazzo, and Troy showed that Orange Serum Agar, with a pH of 5.4, effectively supports the growth of Leuconostoc, Lactobacillus, and various yeasts, making it an essential medium for microbiological analysis.

Orange Serum Agar is highly recommended for the examination and quality control of fruit beverages, ensuring the identification and study of spoilage microorganisms to maintain product integrity.
