A 3×5 factorial arrangement completely randomized was applied to sausages using the following factors: fatty mimetic (flour, native starch and pregelatinized starch) and fat substitution (0, 10, 20, 30 and 40%), evaluating their sensorial and instrumental properties with three replicates per treatment. By replacing 30 and 40% of the fat in the sausages, these were less bright and redder, while 10% of the fat replaced by native starch and pregelatinized, the values of luminosity increased (p≤0.05) with respect to the control treatment. By replacing 10 and 20% of fat with mimetics, an improvement in texture was observed, reducing the hardness between 10.23 and 25.86%. Sensory evaluation showed that this substitution did not cause any alteration in the acceptability of the sausages (p≤0.05) with respect to the control formulation, with the exception of those made with native starch at 20% substitution, which was less accepted in flavor. The substitution of 10 and 20% of fat for flour and pregelatinized starch are the most recommended in the production of sausages with better sensory acceptance, texture and luminosity.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88429950","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}

Red Tilapia (Oreochromis sp.) scales (RTS) have essential protein contents; therefore, those represent an opportunity to obtain hydrolysates, which may present biological activities of interest. For the extraction of the protein, it is possible to use chemical methods such as alkaline hydrolysis. The factors of central composite design (DOE) were NaOH concentration (0.5 to 2M), temperature (40 to 60°C) and percentage of scales (2.5 to 7.5%). The response variables were: protein (g/L), antioxidant capacity (ABTS and FRAP) and percentage of iron chelating activity (ICH). The hydrolysis time was evaluated in 2, 4 and 8 h in a 500 mL reactor with constant stirring. It was possible to obtain significant models for the variables assessed and those showed that with high levels of temperature, NaOH concentration and substrate concentration get a higher concentration of soluble protein without affecting the biological activities evaluated. The quantity of the protein obtained for the optimal DOE conditions was 20 g/L, with an extraction yield of 98%. The best time to get proteins with bioactivity was 2 h. This study evidenced the obtainment of protein hydrolysates from RTS with antioxidant and iron chelating activity using alkaline hydrolysis.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83396047","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}

Aseptic milk samples were taken from three (3) companies, stored at temperatures between 0-4°C. Make dilutions were performed with peptone water and plaque (MRS agar), species were purified by morphology, reaction to oxidase case, catalase and gram staining. The Identification of the isolated species was done using the API 50 CH system (BioMerieux). The results of the first two (2) companies showed the species Lactobacillus paracasei ssp paracasei 3, with a percentage of identification above 99.5%. Third company showed growth of yeast colonies without the presence of lactic bacteria. There was no growth of other bacteria during the investigation, possibly due to the use of inhibitory substances by producers, such as hydrogen peroxide, during the transfer of milk to processing centers. It is concluded that one of the autochthonous bacteria of raw milk that affect the final characteristics of the coastal cheese is Lactobacillus paracasei ssp paracasei 3 since it showed a considerable growth rate, despite possible inhibition conditions. This species can be used in starter's cultures and inoculated in pasteurized milk, to obtain typical organoleptic characteristics of cheese made from raw milk.","PeriodicalId":7316,"journal":{"name":"Advance Journal of Food Science and Technology","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73564644","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}

Three sources of Pregelatinized starch (corn (PCS), cassava (PCAS) and yam (PYS)) were evaluated varying in ratios of 20/40, 30/30 and 40/20 starch/fishmeal. It was determined the content of fat, protein, moisture, ash, pH and color parameters, which were compared with a commercial cream. In addition, the shelf life of the creams was established through the moisture gain by absorption isotherms, at a temperature of 35°C, varying the relative humidity between 34.78 and 91.66%. Very favorable nutritional levels were obtained in barracuda creams with fat and protein contents between 0.98-1.77% and 16.30-41.97%, respectively, with reference to the commercial cream. The percentage of moisture in the cream allowed to establish the useful life through isotherms of absorption, indicating that, with a percentage of compaction of 100, 20, 10 and 5%, the stability time of the cream is 33.39; 6.68; 3.34 and 1.67 months, respectively.

A 3×2 factorial experimental design was used, evaluating the covering of three shapes (bijao leaf, self-adhesive transparent film and a sample not covered) during two periods of refrigeration (72 and 96 h). Rheological and physicochemical properties such as water and pH retention were analyzed. A sensory analysis was developed on 30 panelists where an organization test was used to know the degree of acceptance according to the hardness of the samples. The results of the texture profile and tenderness test showed that the cuts of Biceps femoris muscle covered with Calathea lutea show less shear force and more softening than the other treatments. On the other hand, the results show more water retention capacity than the samples not covered with the treatment. Likewise, the sensory panel showed the preference of covered meat for presenting less hardness. We can conclude that the covering with Calathea lutea confers more properties to achieve a softer cut from the muscle.

The people who continued in the process received training and training in sensory evaluation of cocoa liquor. The Colombian cocoa is classified as fine and of aroma, which generates an added value for the commercialization of the grains. In the municipality we do not have personnel trained in the sensory evaluation of cocoa liquor, for this reason, the need arises to create a panel of judges trained in the Center for Agricultural Sector Assistance, this process was supported by the Colombian Technical Guides 165, 226, 245, 246 and the Colombian Technical Standard 4129, 3929. With the results of the process, the sequential analysis was applied, with a level of significance of 95% and an upper limit of selection of 70%.
