GIAbiochem ®

Seafood constitutes an important source of omega 3 fatty acids, high quality protein, vitamins and minerals in human nutrition. Besides, in Aquaculture production, the nutritional composition of feeds and ingredients is not only critical for aquatic animals growth, but also greatly affects their quality for the consumers. GIAbiochem service offers a wide range of analysis to determine the nutritional quality of these and other alimentary products.

The services offered include:

  • Determination of the nutritional properties of seafood and other alimentary products.
    1. Ingredients, feeds, organisms, organs and tissue composition including:
    2. Proximate composition (crude protein, total lipids, ash and moisure).
    3. Phospholipid content and lipid class composition.
    4. Fatty acid profiles of total lipids or specific lipid classes.
    5. Carotenoids, vitamin A and vitamin E contents.
    6. Aminoacid profiles.
  • Study of the enzymatic activity in different organs and tissues.
  • Feed and ingredients quality determined by peroxide values, biogenic amines, etc. in cooperation with GIAqualities.
  • Systematic control of feed quality for commercial producers.

The GIA Quality service GIAqualities offers to both enterprises and research entities different types of quality determinations for aquatic products including organoleptic quality of aquatic products, freshness evolution along shelf life during ice storage, or consumer preferences, etc. The sensory evaluation is carried out by a trained panel of experts or untrained potential consumers in specific facilities designed under standard conditions for the appropriate evaluation of quality. Freshness is studied both instrumental and sensory protocols, as QIM, nucleotic degradation, biogenic amines or texture profile. Besides, consumers tests are design and conducted, including qualitative and quantitative approaches.

Analysis of physical qualities of acuatic products:

  • Instrumental Texture caracterization of whole fish and fillets, and, in cooperation with GIAhistopath® muscle gaping due to proteolytic activities post mortem.
    • Fillet and skin color and, in cooperation with GIABiochem, pigmentation.
    • Liquid holding capacity
  • Determination of sensorial characteristics and organoleptic properties of standarized cooked acuatic products:
    • By trained panels (10-30 persons) to rate the intensity of aspect, aroma, flavor, texture, color, etc.
    • Consumer testing to determine aquatic products acceptance by large panels of untrained people recruited from potential consumers.
  • Effects on shelf life and frozen storage of seafood products, including freshness determination based on fish appearance, texture and odor, Quality Index Method (QIM), TBARS, pH, etc.
  • Morfological characterization, including X ray and, in cooperation with GIAhistopath®, specific staining.
  • Contaminants contents in acuatic products.
