They are carcinogenic and can affect food quality and safety. Effect of fermentation on aflatoxin content of ogi produced from moldy maize was investigated in this study. Moldy and non-moldy maize grains were fermented and proximate, microbial and aflatoxin content analyses were carried on the samples for 72 hr fermentation periods at 24 hr intervals. Ogi was produced using the standard method of production and dried to give Ogi flour. Results of the proximate analysis show decrease in protein, crude fiber, ash and carbohydrate contents during the fermentation periods. The fat content of steeped non-moldy maize increased (4.32%-4.36%) compared to that of moldy maize (3.94%-4.01%), but they are not significantly different. Microbial analysis showed a reduction in yeast and mold counts, with values ranging from 7.0-0.50 CFU /g × 104 in non-moldy maize and 11.45-2.45 CFU/g × 104 for moldy maize at the end of 72 hr fermentation. Increased values of Lactic acid bacteria counts were observed at 48hr fermentation for both samples. During fermentation, aflatoxin contents in the moldy grains reduced from initial concentration of 58.00 μg/kg in the raw maize sample to 3.13 μg/kg at 72 hr fermentation period. This study has shown that aflatoxins content in moldy maize can be reduced by natural fermentation processes.","PeriodicalId":15727,"journal":{"name":"Journal of Food Processing and Technology","volume":"18 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2019-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86650740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Compared with the control JSP, UAE improved the proteolysis process, as confirmed by an increase in the degree of hydrolysis (DH; p<0.05), as well as the Oil Holding Capacity (OHC) and emulsifying stability (ES). Moreover, the UAE treatment increased the protein solubility (PS), while the Least Gelation Concentration (LGC) did not exhibit significant changes. Scanning Electron Microscopy (SEM) demonstrated that UAE disrupted the microstructure of the JSP, exhibiting larger aggregates in comparison with control JSP. Fourier transform infrared (FT-IR) spectra indicated that the UAE treatments induced molecular unfolding by increasing the α-helix, β-turn and random coil content, as demonstrated by increased surface hydrophobicity (H0-ANS).

Regardless of meat type, the moisture content decreased (P ≤ 0.05) with increased storage period. The opposite was true for the fat and ash meat compositions. When the interaction of meat type (MT) and SP was considered, beef meat had higher (P ≤ 0.05) moisture and fat contents than poultry meat.

Proximate and mineral compositions, functional properties of flour products and sensory acceptability of the porridge were analyzed using standard methods. A preliminary experiment was done by soaking and germination of chickpea to improve acceptability and nutritional contents of the porridge. Based on the preliminary results, the experiment was done by preparing seven formulations of the composite flours. The formulated flours porridges were prepared in a such a way that ratio of Kocho: Chickpea in percent (100:0.0 (control), 70:30 un-soaked chickpea, 70:30 soaked chickpea, 70:30 germinated chickpea, 60:40 unsoaked chickpea, 60:40 soaked chickpea and 60:40% germinated chickpea). The porridge prepared from blending of chickpea 30% and 40% with kocho flour observed significantly highest value in proximate composition, mineral content and functional properties (p<0.05). Porridge prepared from T3 (70%:30%) and T6 (60%:40%) which means Kocho with germinated chickpea flour next to soaked chickpea flour products accepted by most panelists for sensory attributes and it was significantly different from the control. The proximate composition revealed that as the proportion of germinated chickpea flour increased, the protein content of the porridge is increased. Protein-energy malnutrition which affects children in case of eating protein low food Kocho, can be minimized by blending chickpea flour when porridge preparation. The product prepared from 70% of kocho and 30% unsoaked chickpea flour had the lowest bulk density content. Whereas the product prepared from 70% of kocho and 30% germinated chickpea flour was observed highest in oil absorption capacity content The product prepared from 60% of kocho and 40% germinated chickpea flour had highest water absorption capacity.

The key aim of this study was to investigate the influence of protein concentrations (Cprotein) and process parameters on microparticulation of whey protein using the hot extrusion process. During the extrusion process, demineralized water was used to reach the desired Cprotein of 20, 25, 30 and 35% respectively. The experiments were carried out using a corotating twin-screw extruder (ZSE18HP) with an L/D ratio of 40:1 at 90°C as the maximum barrel temperature. The particle size of the microparticulate whey proteins (MWPs) was measured using laser diffractometry, and particle size distributions were calculated by Fraunhofer approximation. The colors of all extruded samples were determined using the CIE L*a*b* system. Additionally, the microscopic properties of particles were determined using a digital microscope with a high-magnification lens. The statistical analysis and data fitting were done using SPSS. Protein concentrations and showed a significant (p<0.001) influence on the particle size distribution of microparticulated whey proteins. The particle sizes of MWPs declined by raising the Cprotein up by 30%. On the other hand, the increase of screw speeds caused the particle sizes to decrease. However, 35% of Cprotein and a screw speed of 200 rpm gave us the opposite results. The particles that were d50 ≤ 5 µm and d50 ≤ 3 µm in size were observed from the screw speed range of 400 rpm to 600 rpm and 800 to 1000 rpm respectively. In terms of particle size distributions, the screw speeds of the extruder were also statistically significant (p<0.001). In conclusion, the particle size distributions in the so-called microparticulation process can be controlled through the manipulation of the Cprotein as well as the screw speed of the extruder.","PeriodicalId":15727,"journal":{"name":"Journal of Food Processing and Technology","volume":"34 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78877947","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study was aimed at assessing the effects of boiling and roasting on the quality of the lipid of an adult Large white pig meat (Longissimus dorsi muscle) enriched with five spices at various concentrations. The proximate composition of uncooked meat was evaluated and the lipid quality was assessed by chemical characterization of oils extracted from the meat. Results revealed that meat had a high level in the water (66.08%); lipids (16.4%); proteins (15.95%); and a low level in ash (1.15%) and carbohydrates (0.42%). It also contains minerals such as magnesium (147.28 g/kg); sodium (2.88 g/kg); phosphorus (1.42 g/kg) and calcium (1.22 g/kg). All the treatments significantly (p<0.05) increased the acid value of fat extracted from pig meat; the values obtained agree with those recommended by the Codex Alimentarius. The treatments: Boiling+Allium sativum (5 g); Boiling+Zingiber officinale (3 g); Boiling+Allium cepa (3 g) and Boiling+mixture together reduced the alteration of double bonds and the formation of hydroperoxides. The principal component analysis reveals a relationship between TBARS value and acidity. Also, it shows that TBARS and peroxide values were more effective to induce lipids oxidation in meat products after cooking. In general, adding spices are more effective at limiting lipids oxidation of meat during cooking treatments compared to the control. Practical applications: Boiling with Allium sativum, Allium cepa and Zingiber officinale powders could be applied in order to preserve the lipid quality of pig meat and health of consumers.","PeriodicalId":15727,"journal":{"name":"Journal of Food Processing and Technology","volume":"47 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79089599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
