Six yoghurt treatments were made, control yoghurt was made by adding 3% non-fat dry milk to cow's milk while the other five treatments were made by fortifying cow's milk by 0.5, 1.0, 1.5, 2.0 and 2.5% whey protein hydrolysate respectively and 3.0% nonfat dry milk to each treatment. All yoghurt treatment was stored in refrigerator for 12 days and was sampled when fresh and at 3, 6, 9 and 12 days for chemical, rheological, microbiological analysis and sensory evaluation. The obtained results indicated that adding whey protein hydrolysate to cow's milk caused a significant increase of total solids, total protein and ash contents, titratable acidity, while decreased pH values and whey syneresis of yoghurt treatments and these effects were proportional to the rate of adding whey protein hydrolysate. Also, adding whey protein hydrolysate up to 2.0% increased the scores of organoleptic properties and treatment T4 that made with adding 2.0% whey protein hydrolysate was the most acceptable yoghurt treatments. Total solids, total protein, ash and fat contents of all yoghurt treatments did not change significantly, (P > 0.05) during storage period, while titratable acidity increased. Whey separation decreased during storage period up to the sixth day of storage period then increased up to the end of storage period, while the scores of organoleptic properties were almost stable up to the ninth day of storage period.","PeriodicalId":249613,"journal":{"name":"Menoufia Journal of Food and Dairy Sciences","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131768805","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 obtained results revealed that, physical properties of brown and white rice varied from one variety to another. Giza 182 rice variety was significantly the longest length among Giza 179 rice variety. In addition, parboiling process had no effect on the length and width of either brown or the white rice at P ≤ 0.07.The paddy rice of raw (Giza 179) had the highest percentage of broken grains and the lowest percentages of head rice and Brown rice as compared with (Giza 182) variety, where parboiling process led to decrease the percentage of broken rice from 32.40 to 4.28% for Giza 179 and from 16.50 to 5.50 for Giza 182.In addition, parboiling process help to increase the head rice and white rice percentages. Water uptake, sedimentation value of white rice were significantly higher than that of brown rice. white rice variety of Giza 179 had the lowest cooking time among all of the tested rice samples (17 min.). water uptake and sedimentation values decreased as a function of parboiling process but cooking time increased for all rice samples. Gel consistency (GC) varied significantly among varieties in both brown and white rice. Alkali spreading value in brown rice varieties showed lower values in comparing with white rice varieties. white rice variety of Giza 182 had the highest Alkali spreading value, Elongation and Amylose content among the other varieties. Moreover, it were decreased upon subjecting rice to parboiling process. Brown rice of two rice varieties had higher contents of crude protein, ether extract and ash but lower content of total carbohydrates than those of white rice. Parboiling process lowered the percentage of the crude protein and ether extract in both brown and white rice .whereas, it increased the ash and minerals content in white rice samples. The cooked white rice of Giza 182 variety had the highest mean scores for the palatability characteristics among all of the tested rice samples. In addition, parboiling process helped to decrease the mean score for the palatability characteristics but the values were still acceptable by the panelists.","PeriodicalId":249613,"journal":{"name":"Menoufia Journal of Food and Dairy Sciences","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116825377","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}

A specific model has been developed to boost the safety and quality of potato chips product in this plant. The prerequisite programs (PRPs), operational prerequisite programs (OPRPs), hazards, critical control point (CCP), preventive measure, critical limits, monitoring procedure and corrective actions have been designed in this HACCP plan. Microbiological analysis for incoming flavors were within the acceptable limits and thus the incoming shipments were accepted and no acceptance from the supplier in case of out of the acceptable limits. The results showed that microbiological examination of raw potatoes before and after frying that frying process could significantly reduce all microorganisms in raw potatoes to the acceptable level on two processing lines. A program of cleaning and disinfection of production lines and a personal hygiene program for the workers and ensuring the effectiveness of them as well as the quality of the water entering the manufacturing process.
