Impact of non-protein nitrogen substances on grape pomace silage quality

IMPACt OF hUMUS SUBStAnCES On GROUnDWAtER QUALIty

humic substances (hS) constitute a large part of organic matter found in aquatic environment. the hS strongly interact with both inorganic and organic pollutants. Occurrence of the hS in groundwater accounts for many problems with treatment procedures. these natural components cause an increased intensity of water colour, affect its taste and odour, hinder removal of iron, manganese and other m...

Recovery of aromatic aglycones from grape pomace

Procyanidin content of grape seed and pomace, and total anthocyanin content of grape pomace as affected by extrusion processing.

UNLABELLED Grape juice processing by-products, grape seed and pomace are a rich source of procyanidins, compounds that may afford protection against chronic disease. This study was undertaken to identify optimal extrusion conditions to enhance the contents of monomers and dimers at the expense of large molecular weight procyanidin oligomers and polymers in grape seed and pomace. Extrusion varia...

The effect of protein- and non-protein-nitrogen supplements to maize silage on total amino acid supply in young cattle.

I . A total of six diets based on maize silage were formulated to examine the effect of proteinand non-protein-nitrogen, and energy supplementation on the flow of amino acids to the small intestine and the synthesis of microbial amino acids in the rumen of growing cattle. All diets contained 24 g total nitrogen (N)/kg dry matter (DM), of which 550 g N/kg total N was supplied by either urea or f...

Meat Quality and Storage Characteristics of Pork Loin Marinated in Grape Pomace

This study investigated the meat quality and storage characteristics of pork loin marinated in grape pomace powder during different storage periods. The experimental design included six treatments : pork loin containing only 100% water (Control, C); pork loin containing a combination of 20% grape pomace and 80% water (T1); pork loin containing a combination of 40% grape pomace and 60% water (T2...
