Their effects on drying kinetics, physicochemical properties as well as sensory quality were evaluated and compared. Results showed that the total drying time varied with the drying method used and was about 160, 100, 260, and 45 min for MVD, MHAD, HAD and TR, respectively. The effective moisture diffusion coefficients (Deff) were 6.57×10 –9 m2/s, 9.80×10–9 m2/s, 4.14×10–9 m2/s and 6.20×10–9 m2/s for MVD, MHAD, HAD and TR, respectively. Drying resulted in a significant decrease in L* and an increase in a* and b* of the color of products. MVD, MHAD and HAD products had a comparable rehydration ratio and cooking time. Scanning electron microscopy and rehydration process revealed that MHAD and MVD samples had a similar structure with the HAD sample. Drying caused a loss of 6.5–54.9% in the total phenolic content and a loss of 38.4–62.2% in total yellow pigment content. MVD millet displayed the highest total phenolic content (142.56 mg GAE/100 g dry matter) and yellow pigment content (9.56 mg CE/kg dry matter). In sensory evaluation, MHAD, HAD and MVD samples had comparable scores and were all accepted by the panelists, either in dry or rehydrated form. MHAD and MVD can be used as an alternative to hot air drying or traditional roasting in the production of the instant millet due to shorter drying time and better product quality.","PeriodicalId":20332,"journal":{"name":"Polish Journal of Food and Nutrition Sciences","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42175513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, enzymatic treatment of juice has been noted to improve the overall acceptability of juices better than traditional decantation, filtration, and heating methods, which are either expensive or detrimental to the product quality. In this study, pear juice was effectively clarified using partially purified polygalacturonase from an entomopathogenic fungal endophyte Beauveria bassiana SAN01. The optimization of the juice clarification process led to 137% improvement in clarification compared to control, under optimal conditions of 39.37 U/mL enzyme load, 36.87°C temperature and 2.75 h treatment time. Results also showed that the polygalacturonase treatment resulted in a significant decrease in viscosity and an increase in the pseudoplasticity of the pear juice as the rheological data of the juice was observed to fit adequately into the power law model (R2>0.9). Furthermore, the enzyme-assisted juice clarification was found to reduce browning index (-14.34%) and turbidity (-19.72%) while increasing the reducing sugar content (9.55%). Unlike some conventional juice treatments, the polygalacturonase treatment preserved the antioxidant potential and the total phenolic contents of the pear juice as no significant changes were observed after the treatment. This study thus demonstrates the efficacy of a fungal polygalacturonase in improving pear juice quality as well as the potential applicability of B. bassiana enzymes in the food industry.","PeriodicalId":20332,"journal":{"name":"Polish Journal of Food and Nutrition Sciences","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44314562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, two factors with the type of fruit pulps (avocado and mango) and drying tempera - ture (ranging from 80 to 95°C) were investigated. Results showed that in refractance window drying, the evaporation process rapidly occurred, mainly in the falling-rate period with undetectable constant-rate period. The Weibull was the best fit model among eight investigated mathematical models that could determine the drying behavior. The effective diffusivity was found to be from 4.25×10 -10 m 2 /s to 7.24×10 -10 m 2 /s for avocado pulp, and from 4.50×10 -10 m 2 /s to 10.67×10 -10 m 2 /s for mango pulp when the drying temperature was changed from 80 to 95°C. Moreover, the corresponding activa - tion energy was 32.06 and 66.03 kJ/mol for avocado and mango pulp moisture evaporation, respectively, and the highest quality of powders of both dried pulps was obtained after processing at 90°C. The refractance window drying revealed a high potential in the production of fruit powders from avocado and mango due to the high retention of more than 80% of total phenolic content (TPC) and antioxidant activity. TPC could be used as a useful criterion for the evaluation of the drying process in terms of dried product quality.","PeriodicalId":20332,"journal":{"name":"Polish Journal of Food and Nutrition Sciences","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44661650","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is the case with Macrotermes subhyalinus , a species of termite widely consumed in Côte d'Ivoire. This study was carried out to assess the mineral content and their bioavailability in the different castes (winged, queen and soldier) of this species. For this, the levels of antinutritional factors, the levels of minerals and their bioavailability were determined. Magnesium and potassium contents vary respectively from 977.18 mg/100g DM to 1405.45 mg/100g DM and from 6658.20 mg/100g DM to 9879.38 mg/100g DM. The winged M. subhyalinus had the higher levels of copper (62 mg/100g DM) and manganese (2867 mg/100g DM). While the queen had the highest values for sodium (2158.9 mg/100g DM) and selenium (0.67 mg/100g DM). As for M. subhyalinus soldier, it was rich in calcium (3323.4 mg/100g DM), zinc (127 mg/100g DM), iron (2657 mg/100g DM) and molybdenum (0.48 mg/100g DM). Regarding the content of antinutritional factors, the highest values are observed with M. subhyalinus soldier in phytate (451.85±28.49 mg/100g DM) and in tannins (35.32±0.98 mg/100g DM). M. subhyalinus queen has the highest oxalate content (12.57±0.48 mg/100g DM). The calculated molar ratios vary from 0.02 to 0.9 with oxalate and from 0.09 to 35.57 with phytates. These insects could be recommended for children suffering from micronutrient deficiency malnutrition.","PeriodicalId":20332,"journal":{"name":"Polish Journal of Food and Nutrition Sciences","volume":"127 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75843488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
