The analysis comprised: chemical composition, total phenolic and flavonoids content and antioxidant activity of the dried orange juice by-product. The results showed that dried orange by-product contents 8.23% ash, 1.02% fat, 8.12% protein, 78.19% total carbohydrate and 63.05% total dietary fiber. The results showed that the extract yield was 29.89 and 28. 25% and total polyphenolic content recorded 22.615 and 21.045mg/g dried extract while the total flavonoids content recorded5.166 and 4.937mg/g dry extract for methanol: water and ethanol: water extracts respectively. The antioxidant activity of the methanolic and ethanolic extracts of orange juice by-product was assessed using stable DPPH radical. Both orange juice by-product extracts exhibited very strong antioxidant activity with EC50 of 11.67 and 13.21μg extract/ μg DPPH, respectively. Effects of replacement of cake wheat flour with different levels of dried orange by-products (5%, 7.5% and 10%) were investigated regarding sensory aspects. The sensory profile of cake with OJBP showed that addition 5% orange juice by-product as wheat flour replacer in the cake formula improved the appearance, color, taste, odor and overall acceptability of the cakes comparing to the control sample. When the replacement level was increased to 7.5 and 10% all the sensory properties showed significant decrease comparing with the control sample. Orange juice by-product was evaluated as a fat replacer on physicochemical and sensory characteristics of low-fat burger. The results showed that OJBP at all replacement levels reduced the cooking loss, shrinkage % and prolonged the storage stability of the produced burger compared to the control samples. The replacement of fat by OJBP in burger at low level (2.5%) led to improvement of all the sensory parameters. Whoever, at the highest level (7.5%) partially impairs the acceptance of the product compared to the control samples.","PeriodicalId":269546,"journal":{"name":"SDRP Journal of Food Science & Technology","volume":"248 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134179210","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}

Twenty six adult subjects from low-income communities with a recently established food hub were recruited, and their fecal microbiota was analyzed via interrogation of 16S rRNA gene. Among the dietary and biometric parameters recorded for each subject, age was a statistically significant contributor to microbiota composition variability. While healthy eating and body mass indices had no direct correlation between themselves, they displayed opposite effects in structuring microbiota composition. Thus, adopting healthier eating habits might potentially counteract the obesity-related shifts in gut microbial communities.","PeriodicalId":269546,"journal":{"name":"SDRP Journal of Food Science & Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122719919","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}

Various parameters affecting the acylation reaction process, such as the base, solvent, as well as the mole ratio of palmitoyl chloride have been studied, in order to optimize the acylation procedure. The compound 1 in the reaction mixture was separated by silica column chromatography. The compound 1 was confirmed by HPLC-MS and NMR and was identified as the EGCG palmitate (PEGCG). The stability of the EGCG palmitates and EGCG in different conditions were studies. Compared with EGCG, PEGCG showed better inhibition on the activities of α-amylase and α-glucosidase, with IC50 values of 1.64 and 0.22 μM, respectively. These observations open a novel and effective synthetic pathway for derivation of EGCG and suggest that the lipophilic PEGCG may act as an antidiabetic agent.","PeriodicalId":269546,"journal":{"name":"SDRP Journal of Food Science & Technology","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121529357","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}

There are lots of parameters widely used to assess the degree of protein changes. While, not much information was available on using different parameters to investigate changes in proteins of frozen shrimp. The present study was conducted to evaluate the changes in proteins using different parameters, including myofibrillar solubility, myofibrillar size distribution and myofibrillar UV absorption spectrum. Meanwhile, in order to make clear the direct effects of these protein changes on frozen shrimp quality, the variation in total volatile basic nitrogen (TVB-N), texture and microstructure were determined as well. The results of this research may help to better understand the mechanism of frozen shrimp quality deterioration. The results showed that the protein had been changed during shrimp frozen storage which could result from protein freeze denaturation, protein oxidation, protein degradation and other biochemical actions. All the three parameters could well characterize the changes in protein during shrimp frozen storage. It was shown that the TVB-N levels increased, and the texture and microstructure went worse over shrimp frozen storage. These variations could be the results of protein changes.","PeriodicalId":269546,"journal":{"name":"SDRP Journal of Food Science & Technology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130742369","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}

Each deletion removed a cluster of nonessential genes, as deduced by an online prediction program. Phenotype analysis of the mutants with large deletions showed that genome regions YOR124C/YOR134W and YOL020W/YOL011W appeared to be related to ethanol tolerance and high salinity sensitivity, respectively. The loss of CAT5, ADE2, or RGA1 reduced the ethanol tolerance of yeast.

The rats were randomly divided into three groups (n = 10), including normal control group, HMG model group and RPXT treatment group. The toxicity study of RPXT on HMG rats was performed at 500 mg/kg/day by i.g. for 35 consecutive days. Changes of nipple height and diameter, serum sex hormones levels and organ indexes, pathologic changes of mammary gland, heart, liver, spleen, kidney and lung, hematological and biochemical analysis were measured or observed to evaluate the anti-HMG effect and toxicology of RPXT. The expression of AP-2α, P53 and caspase-3 in mammary gland of rats were analyzed by western blot. The results indicated that RPXT could remarkably decrease nipple height and diameter, uterus index and E2 concentration of HMG rat serum, and no toxicity at dose of 500 mg/ kg/day. AP-2α, P53 and caspase-3 expression in mammary gland was significantly decreased in mammary gland of RPXT -treated HMG rats.

It has been reported that oxidative stress and inflammation mainly contribute to the progression of aging. Hence, depletion of reactive oxygen species (ROS) and protective effect against inflammation could be the main strategies to extend lifespan of human beings. Due to side effects of drugs, recent researches focus on herbal medicines over the last two decades. Garlic (Allium sativum) and ginger (Zingiber officinale Roscoe) are the most commonly used dietary seasoning in the world. Previous studies show that garlic lowers blood pressure, cholesterol, triglycerides, homocysteine, boost immunity and decreases oxidative stress and inflammation, which are associated with anti-aging mechanism. Moreover, ginger and its bioactive compounds have shown the suppression of lipid peroxidation and recovered the levels of glutathione (GSH). In addition, ginger has shown the anti-inflammatory effect by decreasing nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor, alpha (IκBα) degradation and impairing nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) nuclear translocation of p65. Scientific evidences suggest that garlic and ginger both showed the protective effects against oxidative stress by depleting ROS and inflammation and extending life span. In this review, we discuss active components of garlic and ginger, and their biological roles in anti-aging, anti-oxidative and antiinflammatory effects.","PeriodicalId":269546,"journal":{"name":"SDRP Journal of Food Science & Technology","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132751162","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}

Results: Sinapine was the predominant phenolic in the canola meal crude extract, while canolol was the only significant phenol in the accelerated solvent extract of canola meal. The deodistillate did not have canolol or sinapine present, but contained high molecular weight phenols of unknown identity. The “test tube” antioxidant assays indicated that canola meal crude extract and sinapic acid both exhibited stronger antioxidant potentials compared to the other extracts. A dose dependent cyto-protection effect was observed under oxidative challenge by H2O2, when cells were incubated with the canola meal accelerated solvent extract, deodistillate extract and sinapic acid.
