Abstract: Not all proteins have the same nutritional value, since
protein quality strongly depends on its amino acid composition and
digestibility. The meat of game animals could be a high protein
source because of its well-balanced essential amino acids
composition. Investigations about biochemical composition of game
meat such as wild boar (Sus scrofa scrofa), roe deer (Capreolus
capreolus) and beaver (Castor fiber) are not very much. Therefore,
the aim of the investigation was evaluate protein composition of
game meat hunted in Latvia. The biochemical analysis, evaluation of
connective tissue and essential amino acids in meat samples were
done, the amino acids score were calculate. Results of analysis
showed that protein content 20.88-22.05% of all types of meat
samples is not different statistically. The content of connective tissue
from 1.3% in roe deer till 1.5% in beaver meat allowed classified
game animal as high quality meat. The sum of essential amino acids
in game meat samples were determined 7.05–8.26g100g-1. Roe deer
meat has highest protein content and lowest content of connective
tissues among game meat hunted in Latvia. Concluded that amino
acid score for limiting amino acids phenylalanine and tyrosine is high
and shows high biological value of game meat.
Abstract: A game animals – elk (Alces alces), deer (Cervus
elaphus), roe deer (Capreolus capreolus) or wild boar (Sus scrofa
scrofa) - every autumn and winter period provide an excellent
investment, diversification of many consumer meals. In last years
consumption and assortiment of game meat products significantly
increase. Investigations about biochemical composition of game meat
are not very much. The meat of wild animals is more favourable for
human health because it has lower saturated fatty acids content, but
higher content of protein. Therefore the aim of investigations was to
compare biochemical composition of ungulates obtained in
Latvia.Investigations were carried out in wild animals different
regions of Latvia. In the studied samples protein, intramuscular fat,
fatty acids and cholesterol were determined. The biochemical
analysis of 54 samples were done. Results of analysis showed that
protein content 22.36 – 22.92% of all types of meat samples is not
different statistically, significantly lower fat content 1.33 ± 0.88%
had elk meat samples and 1.59 ± 0.59% roe deer samples. Content of
cholesterol was various 64.41 – 95.07% in the ruminant meat
samples of different species. From the dietetic point of view the best
composition of fatty acids has meat samples of roe deer.
