Soaking and cooking parameters of raw and treated cooked beans were investigated. The samples were also evaluated for their nutritional, physical and sensory characteristics and in-vitro protein digestibility (IVPD). The data showed that, water absorption values increased as the soaking time increased (14.39 – 21.99 after 1 hr and 76.96 – 88.17% after 12 hrs). Cooking time decreased as a result of soaking process. It was higher (260 min) for raw bean and lower (40 min) for 1% baking powder. The IVPD improved after soaking and cooking. It was 70.35 for raw bean, 83.47 for control and 87.29% for 1% sodium bicarbonate. Total carbohydrates and phenolic compounds decreased for all cooked samples as compared to the raw one. As a conclusion, soaking for 12 hrs with 1% baking powder, discarding soaking solution and using fresh water for cooking is the best treatment to reduce cooking time and improve the nutritional and quality properties of cooked faba beans.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"74 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76114781","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}

This study was carried out to investigate the content of these bioactive compounds in pomegranate fruit along with its antimicrobial and antitumor effects. Pomegranate peel powder and juice were analyzed for its phytochemical constituent content ( total phenols, total flavonoids). Phenols and flavonoids contents were estimated qualitative and quantitative using HPLC technique. Furthermore, antitumor activity was tested in vitro on human cell lines. Likewise, antimicrobial and antioxidant activity were investigated. The results showed that the both ethanolic and aqueous extracts of juice and peels powder have antitumor and antimicrobial activity.Phytochemicals have shown superior content in peels than juice including total polyphenols 61.63 and 15.93 mg/g, and total flavonoids 49.3 and 25.85 mg/g, in peels and juice, respectively. Peels extract has exhibited significant antimicrobial activity higher than aqueous extract of juice at 1000 ppm concentration. Thus, peels and juice extracts demonstrated higher antimicrobial activity against E.coli, fungi and yeast. In the test of pomegranate peels and juice extracts for the protective effect against human cell lines, the pomegranate extracts and AgNPs exhibited significant protective effect.In conclusion, our study suggested that pomegranate fruits or its extracts can use as antitumor and antimicrobial agents. Pomegranate fruits are sources of bioactive compounds such as phenolic and flavonoids with potentially high antioxidant activities.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"149 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85133715","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 Multi-step dry fractionation was applied on buffalo butter oil (BO) for enhancement of the nutritional value and functionality at three different temperatures i.e. 35, 25 and 15 °C, three solids (S35, S25 and S15) and three liquid (L35, L25and L15) fractions was gained. LMF (L15and S15) was significantly higher not only in short chain fatty acids (SCFA) but also in long chain unsaturated fatty acids (LCUSFA), whereas, lower in medium saturated chain fatty acids (MCSFA) than those of BO, HMF(S35) and MMF (L25, S25 and L35) were detected. LMF had positive healthy effect of lower oxidative stability index (OSI) and of the highest nutritional (by ω6: ω3 3PUFA) than other fractions. differential scanning calorimeter (DSC) values for both solid and liquid fractions are significantly (P˂0.05) decreased with decreasing fractionation temperature even in melting or crystallization behaviors. Solid fat content (SFC) was significantly the lowest in LMF at 25OC. The liquid fractions had larger crystals size than those solid fractions and BO. Strong negative correlation between SFC at 20OC and (USFA, SCFA and IV) and strong positive correlation between SFC and (SFA, MCSFA, LCSFA and DSC) were observed. Results will increase the knowledge to improve the processing condition to produce buffalo butter oil fractions with increased functionality and more varieties for more dairy fat products. The chosen dry fractionation temperature resulted in an increase of the functional and nutritional properties of obtained buffalo butter oil fractions.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83349325","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 remaining rats were given tramadol daily and divided into four groups, one of them served as positive control, while the other three groups were treated daily with kiwifruit juice, turmeric water extract and their combination for four weeks. The results revealed that the positive control exhibited significant decreases in serum triglycerides, total cholesterol and HDL-c levels and a significant increase in serum LDL-c as compared to the negative control. In comparing with the positive control, the serum cholesterol, triglycerides, VLDL-c and HDL-c values increased while LDL-c value decreased significantly in the three treated groups which reached the normal values of the negative control. The findings revealed significant decreases in serum levels of ALT, AST, ALP, GGT and total bilirubin and significant increases in total protein and albumin of the treated groups in comparing with the positive control. An improvement of the antioxidant parameters was observed where the serum levels of tumor necrosis factor- α, acetylcholine esterase and total oxidative capacity decreased significantly while the levels of superoxide dismutase and total antioxidants capacity increased in all the treated groups in comparing with positive control group.

Milk was heated at 90oC /10 min and quickly cooled to 42oC (control, without psyllium) and to 60oC for supplementation with PSH at ratios of 0.5, 1.0 and 1.5%, w/v (A1, A2 and A3) and with PSS at ratios of 0.5, 1.0 and 1.5% w/v (B1, B2 and B3) and then cooled (42oC) to be ready for fermentation. The resultant yoghurt was analyzed when fresh and during cold storage (4oC) for 7 and 15 days for chemical, physiochemical and sensory properties. The obtained results for the different treatments with psyllium indicated almost significant increase (P≤0.05) on total solids, total protein and ash content. Generally, titratable acidity gradually increased through storage period and pH decreased with different rates due to type and amount of supplement. PSH and PSS enhanced formation of acetaldehyde and increased carbohydrate at different storage periods and subsequently increaseD the energy of the treated yoghurt. Water holding capacity and viscosity were almost significantly increased by supplement and by amount of both PSH and PSS and with advancing storage period. The control yoghurt had the lowest values of both of them. Organoleptically, the use of PSH or PSS at level of 1.5% (w/v) gave improved body and texture without any adverse impact on the flavour of the prepared product.","PeriodicalId":15746,"journal":{"name":"Journal of Food and Dairy Sciences","volume":"32 2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90734132","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}
