Biological silages from Tunisian shrimp and octopus by-products ArchiMer
Harrabi, Houwaida; Leroi, Francoise; Mihoubi, Nourhene Boudhrioua; Chevalier, Frederique; Kechaou, Nabil.
Biological silages were prepared from shrimp head and octopus viscera by-products recuperated from the Tunisian seafood industry. Physical and biochemical changes and microbiological profiles were determined for raw materials during fermentation and on end products. Results showed that biological silage significantly affected (P<0.05) moisture, protein, and ash contents of shrimp head (CSHS) and octopus viscera silages (COVS). CSHS and COVS were stable, and their final pH values were 4.31 ± 0.01 and 3.71 ± 0.00, respectively. Proteolysis activity was confirmed by a significant increase (P<0.05) of soluble nitrogen and low molecular weight of protein (<260 Da) found on the end products for both silages. Lipid oxidation was delayed by addition of...

Microbiological and physical-chemical characteristics of honeys from the bee Melipona fasciculata produced in two regions of Brazil Ciência Rural
Fernandes,Rachel Torquato; Rosa,Ivone Garros; Conti-Silva,Ana Carolina.
ABSTRACT: The honey from Tiúba bees (Melipona fasciculata) is commercially important in the Brazilian state of Maranhão. However, the absence of any specific legislation for this kind of honey is an obstacle to its increased production and commercialization. Determining the microbiological and physical-chemical characteristics of different Tiúba honey can inform the elaboration of specific legislation. Thus, honey samples from two Water Catchment Areas in Maranhão (Munim and Pericumã, sample size 20 for each) were collected and submitted for microbiological analysis (total coliforms, thermotolerant coliforms, molds and yeasts, Clostridium sulfite reducers and Salmonella sp.) and physical-chemical analysis (moisture content, reducing and non-reducing...
