A 42-day study was conducted to evaluate the effect of genotype: terminal sire line Duroc×F1 (DC×F1); terminal sire line Embrapa MS-115×F1 (MS-115×F1); and MS-115×Moura (MS-115×MO) and three dietary oil sources: soybean; canola; and canola+flax, on performance, carcass traits, pork quality, and fatty acid composition. Genotype affected the technological quality of pork and fatty acid profile. MS-115-sired pigs had better meat color and Duroc-sired pigs had higher intramuscular fat content, more saturated fat and better omega-6/omega-3 ratio. Moura breed influenced positively meat tenderness and intramuscular fat. Diet did not affect the technological quality of the meat. Canola or canola+flax oil diet supplementations increased monounsaturated and C18:3 and decreased C18:2 fatty acids, reducing the omega-6/omega-3 ratio. The best omega-6/omega-3 ratio was obtained through supplementation with canola+flax.

The objective of this study was to analyze the physicochemical and microbiological properties, as well as the bioactive compounds, of flour made from the skin and bagasse of two varieties (Bruno and Monty) of kiwi fruit (Actinidia deliciosa) at two stages of maturation. The flour made with kiwi fruit peel from both varieties showed higher levels of bioactive compounds and antioxidant activity that the flour made with bagasse from both varieties. The flour made with green kiwi fruit skin from the Bruno variety had higher DPPH values and levels of phenolic compounds (1262.34 mg GAE/100g flour), while the Monty variety showed higher FRAP values, vitamin C (189.06 mg/100g flour), flavonoids (486.47 mg/100g flour), chlorophylls (12.13 mg/100g flour) and carotenoids (246.91 μg/100g flour). Flour made from kiwi fruit bagasse can be used to reduce agro-industrial waste. This flour is a promising ingredient which can be used to enrich products providing dietary fiber and bioactive compounds, as well as antioxidant action.

Fermented sausages were produced with 50% replacement of NaCl with KCl and with addition of lysine, disodium guanylate, and disodium inosinate. The sausage production was monitored with physical, chemical and microbiological analyses. The final products were submitted to a consumer study. The replacement of NaCl with KCl did not cause changes in the technological process. However, defects in the sensory quality were detected. Lysine at a concentration of 1% with disodium inosinate (300 mg/kg) and disodium guanylate (300 mg/kg) reduced the sensory defects caused by the replacement of 50% NaCl with KCl allowing the preparation of sensory acceptable fermented sausages with a 50% decrease in sodium.

Charqui meat is a tropical intermediate meat product formulated using hurdle technology, a concept described by Leistner (1,2). Salt, sodium nitrite, dehydration, and packaging are hurdles sequentially applied to inhibit deteriorating microorganisms with the possibility of selecting desirable microbiota. This would characterize charqui and
