Cenci","doi":"10.11648/J.IJNFS.20211005.11","DOIUrl":"https://doi.org/10.11648/J.IJNFS.20211005.11","url":null,"abstract":"Lipidomics is the discipline that studies lipid changes that occur during cellular metabolism. This new approach can be applied to the ketogenic diet (KD) where fats are the predominant macronutrient. After a few days of reduced carbohydrate consumption, glucose reserves become insufficient both for normal fat oxidation via the supply of oxaloacetate in the Krebs cycle and for the supply of glucose to the central nervous system. The alternative energy source is derived from the overproduction of acetyl coenzyme A. This condition, called ketogenesis, leads to the production of higher-than-normal levels of so-called ketone bodies. The acceleration of the production of monounsaturated fats (MF) is so characteristic of obesity that the palmitic-palmitoleic track is indicated as a biomarker even the risk of weight gain. Palmitoleic is known as lipoquine, as it regulates the fat transfer from adipose tissue to muscle. In obesity it increases because it is a defence mechanism of the body to transport fats to the muscle, thus avoiding their excessive accumulation in the liver. The saturated/MF ratio indicates the level of stiffness of the membrane. The increase in membrane stiffness leads to a decrease in the number of insulin receptors predisposing to the onset of diabetes. Each cellular compartment has its own lipid content which can be monitored by lipidomics but the erythrocyte membrane has been shown to have the suitable characteristics to become an important site for lipidomic analysis. Conclusions: KD could be customized based on the results of the membrane lipidomic analysis. The lipidomic profile of an obese subject is characterized by an imbalance of PUFA in favor of omega-6 and by an excess of MF. This imbalance must be taken into consideration in the formulation of the KD protocol: only in this way, the epigenetic structure will be favorable to the establishment of a new balance unfavorable to fat accumulation.","PeriodicalId":14174,"journal":{"name":"International Journal of Nutrition and Food Sciences","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77368337","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}

In order to fully interpret the improvement effect of waxy cultivar Jinuo116, the main food such as dry noodles, quick-frozen noodles and steamed bread were prepared by mixing Jinuo116 flour with different fine flour and whole meal flour, and its improving adaptability was conducted. The quality stability of Jinuo116 planted in six ecological zones had been analyzed firstly, the variable coefficient of grain hardness and protein content were lower 5.0%, wet gluten content was 10.82%. For starch pasting properties, the variable coefficient of peak time was only 1.51%, other pasting properties were all lower 7.59%. For dough properties, the variable coefficient of water absorption was very low (only 0.68%), while that of stability time, weakness and Farinograph Quality Index were 22.82%, 12.80% and 17.95%, respectively. These showed that Jinuo116 had stable grain characteristics, dough rheological properties and starch gelatinization. Then the quality of noodles and steamed bread of mixing flour was identified by blending Jinuo116 flour into non-waxy wheat flour such as Jimai22, Jimai229, Jimai44 and Jizimai1, and showed that Jinuo116 flour could greatly improve the viscoelasticity and smoothness of dry noodles and quick-frozen noodles, and the appending proportions were changed based on the different gluten strength of non-waxy varieties, and the range of blending ratio was from 20% to 40%. While considering the integrated qualities of noodles, the appropriate ratio should be controlled at about 30%. Quality characteristics such as hardness, viscoelasticity, smoothness of noodles made of purple whole meal flour had been improved obviously, and the noodles had better taste quality, so the suitable proportion of flour blending was 20%. The internal structure, toughness and viscosity of steamed bread made of purple whole meal flour were improved markedly, and the best internal quality characteristics were got when the adding proportion was 20%. For its good quality properties especially the outstanding starch characteristics, Jinuo116 flour could be used as blending flour to improve the food quality made of non-waxy wheat.","PeriodicalId":14174,"journal":{"name":"International Journal of Nutrition and Food Sciences","volume":"55 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81526379","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 aim of this study was to determine whether Lactobacillus fermentum PC1 (PC1) cell wall extract (CW) and the spent culture supernatant (SCS) had the capacity to inhibit IL-8 production by Salmonella enterica serotype Typhimurium (S. Typhimurium) infected epithelial cells. Epithelial cell line, HT-29 was treated with CW or SCS of PC1 both pre- and post-infection with S. Typhimurium and the resultant levels of IL-8 protein was assayed. Both the CW and SCS of PC1 was shown to inhibit S. Typhimurium induced IL 8 production in HT-29 cells in the therapeutic and prophylactic models. Furthermore, a secreted molecule produced by PC1 responsible for this effect was identified and characterized. The molecule was produced in mid-stationary phase of growth. This active component was present in both the cell wall extracts and spent culture medium of PC1. The bioactive molecule(s) had a size of Mr 2-30KDa, was heat stable at 90°C for 30 min, insensitive to lipase, distinct from acetic and lactic acid, and optimal function at pH 4.5. The activity of the molecules was inactivated by Proteinase K, Na-metaperiodate and Trypsin indicating that the molecule(s) was a glycoprotein.

Enrichment of cereal with easily affordable legumes, root and tubers having superior nutrients are important approaches to produce nutrient dense and sensorial acceptable food products. Therefore, this study was carried out to develop nutrient dense and acceptable food products from composite flour formulated from finger millet, ground nut, orange fleshed sweet potato and soy bean flours. Accordingly, Two types of composite flours were developed. Composite flour type I consisting 65:35, 70:30, 75:25, 80:20 and 85:15 of finger millet and soybean in proportion, respectively, were formulated for injera making. Composite flour type II consisting 60:20:20:0, 70:20:10:0, 60:20:0:20 and 70:20:0:10 of finger millet, soybean, ground nut and sweet potato, respectively, were used for porridge and kita product making. The moisture, ash, protein, fat, fiber and carbohydrate contents of the formulations were ranged from 8.141 to 9.67, 1.03 to 3.17, 4.38 to 17.17, 0.02 to 15.59, 2.85 to 13.87, 60.41 to 71.57%, respectively. There was a significant difference in water absorption capacity, swelling power, water solubility and oil absorption capacity among the composite flours. Sensory acceptability of Injera made from composite flour consisting of 75:25 finger millet and soyabean, respectively, were more preferred by panelists than other proportions. Sensory attributes data showed that porridge made from composite flour formulated from 60:20:20 of finger millet, soyabean and sweet potato were highly preferred by panelists in all sensory attributes. On the other hand, Sensory acceptability of kita made from composite flour formulated from 70:20:10 of finger millet, soyabean and sweet potato, respectively, achieved highest sensorial scores. Therefore, blending of finger millet with nutritious legumes, root and tubers crops would be recommended in production of nutritious and sensorially acceptable value added food products for different purposes.","PeriodicalId":14174,"journal":{"name":"International Journal of Nutrition and Food Sciences","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91306364","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}

Therefore, in the present study, the possibility of replacing sucrose with sorbitol and maltodextrin with Nigella Sativa to produce low-calorie dark chocolate will be investigated. To prepare low-calorie dark chocolate, sorbitol was used in four levels (0, 10, 20, 30%) and Nigella Sativa on in four levels (0, 3, 6, 9%). The effect of different levels of replacement of these compounds on some chemical properties (moisture, fat, protein, carbohydrates, ash), texture (hardness), color (indices L*, a*, b*) and sensory (color, Taste, mouthfeel, and general acceptance) were assessed. Statistical analysis was presented using SPSS 16 software as a completely randomized design. The results showed that significant difference was observed in the fat, protein, carbohydrate, and ash content of the samples containing sorbitol. Samples with higher levels of sorbitol replacement had higher moisture content and lower tissue hardness. The reduction of sucrose had no significant effect on the sensory properties of chocolate samples. As the levels of Nigella Sativa substitution increased, the moisture, fat, and carbohydrate content decreased, and the protein, ash, and texture hardness of the chocolate samples increased. Sensory characteristics, including oral sensation and general acceptance, decreased significantly with increasing levels of Nigella Sativa replacement. The results of color parameter analysis also showed that by increasing the percentage of Nigella Sativa on substitution in the chocolate formulation, the amount of L* component was reduced and the amount of a* and b* components was increased. According to the results of this study, the best sample in terms of chemical, textural and sensory properties of chocolate was produced with 10-20% replacement of sugar with sorbitol and 3-6% replacement of maltodextrin with Nigella Sativa.","PeriodicalId":14174,"journal":{"name":"International Journal of Nutrition and Food Sciences","volume":"21 1","pages":"54"},"PeriodicalIF":0.0,"publicationDate":"2021-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77789981","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 collected information was analyzed with XL-STAT 6.1.9 and also with the variance analysis (ANOVA) at the 5% threshold. The result shows that most of the production is done by women with an average age of 31 ± 1, 08. These producers are mostly traders. However, beef is much more sought after for processing at the expense of other meats for its yield and availability. The average drying time is 2 days during the dry season and 5 days during the rainy season. Two drying methods have been identified, the first of which is the mat and it is the most used and the second is the rope. From the point of view of hygiene, most producers do not respect hygiene rules and they use certain food additives (salt, oil, etc.) for processing. Regarding consumption, the “charmoute” is very popular with the population of Abechosies especially women with an average age of 35 ± 1.57. Most of these consumers are of the Muslim religion. It shows that 85.44% consume this meat with a frequency of consumption per week (70%).

In the second procedure, basil leaves collected as in the first procedure were in separate batches stuffed into the distillation bottle with 200ml of distilled water. Distillation was carried out for 2 hours and distillates collected and stored in tightly sealed plastic bottle labeled as subunits of sample B. The samples (A and B) including their subunits were (within 30 minutes of extraction) subjected to spectrophotometry, pH, and Total soluble solids (TSS) analysis. A 20 man trained panelist were employed in sensory evaluation of the (300g leaf) extracts (after storing at 4°C for 96hours) in terms of colour, flavour, flavour interference and general acceptability. Furthermore, 20ml of each (300g leaf) extract of Aand B were poured into a curvet of 2mm pathway. These were one after the other placed into an electric circuit with the poles submerged into opposite ends of the curvet. The following parameters were read from the meters when the circuit was completed: current, voltage and resistance to flow of electricity across the sample. Sample A (the extract made by the modified traditional practice) had the highest general acceptability compared to sample B and the natural leaf (control sample). It had significantly lower color and flavor interferences, with average of 8/10 flavor intensity recording. Resistance to flow of electricity for both samples (A and B), were inversely proportional to leaf orflavour extract concentration with a gradient of 0.001. It is therefore possible to compute concentrations of flavor components from resistance to flow of electricity with gradient and intercepts derived from graph (Figure 1). TSS, pH and temperature of samples followed the same pattern as electrical resistivity.","PeriodicalId":14174,"journal":{"name":"International Journal of Nutrition and Food Sciences","volume":"83 1","pages":"20"},"PeriodicalIF":0.0,"publicationDate":"2021-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87374958","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}
