Study of chemical changes in microsilages of exoskeletons of shrimp (Litopeneus vanamei) and grasshopper (Sphenarium purpurascens) during fermentation in solid medium
Fermentation in a solid medium is a technique used for the production of chitin, pigments, proteins and lipids. In the present work, changes in the chemical and microbiological composition were evaluated in micro silages of shrimp (Litopeneus vanamei) and grasshopper (Sphenarium purpurascens) exoske...

| Sumario: | Fermentation in a solid medium is a technique used for the production of chitin, pigments, proteins and lipids. In the present work, changes in the chemical and microbiological composition were evaluated in micro silages of shrimp (Litopeneus vanamei) and grasshopper (Sphenarium purpurascens) exoskeletons fermented with a commercial inoculum of Lactobacillus plantarum AVG-112. The amount of molasses for fermentation, the proximal composition and the microbiological count of the silages were determined. The waste was mixed with sugarcane molasses as a carbon source and inoculated using a commercial strain (Lactobacillus plantarum AVG-112). After 5 days of fermentation, both silages presented acceptable physical and chemical characteristics. Total coliforms, molds and yeasts were not present and were inhibited by the ensiling process. We concluded that fermentation in a solid medium has suitable characteristics for use as a supplement in foods for aquatic organisms. |
