In this study, peanut protein concentrate (PPC) was substituted for soy protein concentrate (SPC) in Vietnam emulsion-type sausage manufacture. Peanut protein concentrates yielded from the conventional and the combined ultrasonic and enzymatic extraction were used in the preparation of sausage samples PPC1 and PPC2, respectively. Soy protein concentrate was used in the sausage sample SPC as a control. Ten sausage samples including PPC1, PPC2, SPC and seven commercial samples in which soy protein (SP) was used were tested in three experiments. Instrumental Texture Profile Analysis (TPA), Flash Profile, and 9- point hedonic scale were conducted to observe sample differences. The instrumental TPA results indicated that PPC1 and PPC2 were insignificantly different from the control and one of the SP-added samples for hardness, springiness, and adhesiveness; but significantly for cohesiveness. In the first two sensory dimensions, assessors discriminated samples into three distinct directions in which PPC1 and PPC2 were positioned closely to SPC and two commercial SP-added sausages. Preference map further showed the same percentage of satisfied consumers - clustered with partial least square (PLS) regression - toward PPC1, PPC2, SPC, and the two commercial SP-added sausages. In general, the results proposed the potential use of PPC as a substitute for SP in Vietnam emulsion-type sausage production.

And Performance

Soy protein concentrate improves nutrient utilization and growth performance compared to soybean meal, and diets with a low crude protein (CP) level decreases diarrhoea. The objectives were to (1) test a low CP diet based on different soy products, and (2) to test a very-low CP diet (15.1%) with amino acids (AA) on diarrhoea and productivity. A total of 5,635 weaned pigs (~28 days), were assigned to five dietary treatments; PC (positive control): Standard CP levels (192, 189, 191 g/kg CP) with 2500 ppm ZnO; NC (negative control): Same as PC without ZnO; SP (Soy protein concentrate): Low CP levels (176, 174, 191 g/kg CP); SB (Soybean meal): Low CP levels (177, 176, 191 g/kg CP); and XLA (X-low CP + AA): Very low CP levels (154, 151, 191 g/kg CP) with AA. The PC and XLA diets reduced diarrhoea by 41 and 61%, respectively, compared to the NC group, while no difference between SB and SP were observed. The XLA diet reduced feed intake and daily gain compared with PC and NC, where SP, SB, and XLA had a poorer feed conversion compared with PC. Conclusively, the SP and SB low-protein diets did not reduce diarrhoea or growth performance, whereas the XLA diet decreased both diarrhoea and performance.

AbstractWith an unsupervised GC–MS metabolomics approach, polar metabolite changes of the microalgae Coccomyxa melkonianii SCCA 048 grown under standard conditions for seven weeks were studied. C. melkonianii was sampled at the Rio Irvi River, in the mining site of Montevecchio-Ingurtosu (Sardinia, Italy), which is severely contaminated by heavy metals and shows high concentrations of sulfates. The partial-least-square (PLS) analysis of the GC–MS data indicated that growth of C. melkonianii was characterized by an increase of the levels of threonic acid, myo-inositol, malic acid, and fumaric acid. Furthermore, at the sixth week of exponential phase the lipid fingerprint of C. melkonianii was studied by LC-QTOF-MS. C. melkonianii lipid extract characterized through an iterative MS/MS analysis showed the following percent levels: 61.34 ± 0.60% for triacylglycerols (TAG); 11.55 ± 0.09% for diacylglyceryltrimethyl homoserines (DGTS), 11.34 ± 0.10% for sulfoquinovosyldiacylglycerols (SQDG) and, 5.29 ± 0.04% for lysodiacylglyceryltrimethyl homoserines (LDGTS). Noteworthy, we were able to annotate different fatty acid ester of hydroxyl fatty acid, such as FAHFA (18:1_20:3), FAHFA (18:2_20:4), FAHFA (18:0_20:2), and FAHFA (18:1_18:0), with relevant biological activity. These approaches can be useful to study the biochemistry of this extremophile algae in the view of its potential exploitation in the phycoremediation of polluted mining areas.
