White shrimp (Penaeus setiferus) were held at 0, 10, 20, 30, 37, and 44 C for 3, 6, and 24 h. Serious quality deterioration, as evidenced by off-color development (red and orange pigmentation) and off-odor development, was beginning to occur in shrimp held for 3 h at 30, 37, and 44 C, for 6 h at 20 C and for 24 h at 10 C. Red color development was evident in shrimp held at 30 and 37 C, orange color in those held at 44 C. Putrid odors appeared more rapidly in shrimp held at 37 than at 44 C where shrimp developed cooked-shrimp odors. Large increases in bacterial counts at 30–44 C (after 6 and 24 h) were usually accompanied by putrid odors. Tissue pH changes were erratic and small. Total volatile nitrogen (TVN), free amino acid nitrogen (AA-N), and urea production increased with storage temperature during the 3- and 6-h storage experiments. Musty and cooked-shrimp off-odors developed in the shrimp as a result of chemical and/or enzymic activity while putrid and sour odors were produced by bacteria growing in the shrimp.

Reducing Substances

White shrimp (Penaeus setiferus) washed with ethanol and sterile water were inoculated with a fluorescent Pseudomonas, non-fluorescent Pseudomonas, Bacillus, and a coryneform bacterium. Washing reduced the microbial load but growth occurred on control samples during refrigerated storage. Samples inoculated with Pseudomonas became putrid 2–3 days sooner than their controls. Addition of coryneform bacteria delayed spoilage. Shrimp inoculated with Bacillus spoiled at the same time as the non-inoculated controls. Inoculation of shrimp with Pseudomonas species (a) retarded development of melanosis; (b) produced volatile nitrogen in the atmosphere surrounding shrimp but only after spoilage had taken place; (c) caused higher levels of water-soluble protein, non-protein nitrogen, and total volatile nitrogen than in their corresponding controls; and (d) reached higher pH levels sooner than the controls. No significant changes occurred in volatile reducing substances. Sterile shrimp juices exhibited more extensive melanosis than juices inoculated with Pseudomonas. No marked changes in amounts of soluble protein or non-protein nitrogen were noted upon storage of inoculated juices. Juices inoculated with Pseudomonas had higher levels of total volatile nitrogen after storage than comparable controls. Proteolysis by the fluorescent Pseudomonas was indicated by major changes in elution profiles on Sephadex G-100. Compared with sterile controls, levels of free amino acids decreased in juices inoculated with Pseudomonas or Bacillus and stored at 5 C.
