Pooja Nikhanj, Gurliin Kaur
In the present study, disinfectant pre-treatment conditions were optimized for Fresh cut salad vegetables after evaluating bactericidal efficacy of the five different disinfectants viz. Sodium hypochlorite, potassium metabisulfite, citric acid, acetic acid and benzoic acid. Sodium hypochlorite @ 100ppm was selected for disinfectant pretreatment of fresh cut vegetables viz. cucumber, carrot and tomato through physicochemical and microbial analysis. Optimization of pre-treatment conditions viz. temperature, pH and contact time was statistically designed and analyzed using response surface methodology. Numerical optimization of results revealed a temperature of 6.5, 10.0 and 6.5°C; pH 6.0, 7.0 and 7.0; contact time 23.0, 8.0 and 30.0 minutes was found to be optimized for fresh cut cucumber, carrot and tomato disinfectant pretreatment with a desirability level of 94, 94 and 92%, respectively. Shelf life analysis of pre-treated (under optimized conditions) and untreated fresh cut vegetables stored under refrigeration conditions (5-7°C) revealed enhancement in shelf life of treated fresh cut vegetables from 6, 9 and 6 days to 9, 12 and 9 days of fresh cut cucumber, carrot and tomato, respectively. During shelf life period, all physicochemical parameters of pre-treated fresh cut vegetables differed non-significantly along with microbial load under acceptable limits and a good sensory score.

A Review of Cooking of Potatoes (Solanum tuberosum L.) Served in Large-Scale Food-Service Systems, Including Industrial Pre-Treatments 马铃薯(Solanum tuberosum L.)烹饪技术综述服务于大型食品服务系统,包括工业预处理
K. Sjölin, M. Rayner, J. Purhagen, I. Sjöholm
Potatoes (Solanum tuberosum L.) often constitute a meal’s main carbohydrate source. When consumed outside the home, dishes are often prepared in large-scale food service systems, like school canteens and hospitals. To manage the logistics of serving the required quantities of potatoes, raw tubers must be prepared by washing, industrial peeling, preservative actions, and packaging to stand transportation and storage before cooking. There are several steps of pre-treatment, packaging, transportation, and cooking techniques that differ from traditional preparation at home, and each of these steps— or more likely a combination of several steps— might contribute to reduced quality in terms of enzymatic discoloration, microbiological failure, and subsurface hardening. In this review, the effect of each of these steps on the potato tuber; from industrial peeling to steam-cooking in the large-scale food service system, has been studied to understand where the most significant quality changes occur, and to understand the combined impact of different actions.  
马铃薯(Solanum tuberosum L.)通常是一餐中主要的碳水化合物来源。在户外消费时,菜肴通常是在大型食品服务系统中准备的,比如学校食堂和医院。为了管理供应所需数量土豆的物流,原料块茎必须经过清洗、工业剥皮、防腐和包装,以便在烹饪前经得起运输和储存。预处理、包装、运输和烹饪技术的几个步骤与传统的家庭制备不同,这些步骤中的每一步——或者更可能是几个步骤的组合——都可能导致酶变色、微生物失效和表面下硬化等方面的质量降低。在这篇综述中,这些步骤对马铃薯块茎的影响;从工业剥皮到大规模食品服务系统中的蒸汽蒸煮,研究了最显著的质量变化发生的地方,并了解了不同行动的综合影响。

Design and Development of Domestic Solar Dryer with Comparative Analysis of Nutritional Aspect of Dried Raisins 国产太阳能干燥机的设计与研制及干葡萄干营养成分的比较分析
S. Dubey, K. Bhayani, C. Bhatt, S. Maiti, Sandhya Mishra
Solar dryer technology is simple and can be implemented by households and small communities due to its simplicity. The suitable design of the absorber/collector is very vital for any solar drying system as the collector efficiency plays a key role in determining the overall system drying efficiency. To study the practical applicability of a developed solar dryer, grapes were dried in the drying chamber of a designed and developed solar dryer and for comparison, in open sunlight. Faster drying was noted for the grapes dried in the unit. The study on nutritional aspects indicated that solar drying process retained the major nutritional components like total sugars, total proteins and total lipids in raisins. The comparison between the solar dried raisins and open sun dried ones showed a higher ash content of 2.71% with solar dried ones and 1.95% in case of open sun dried raisins. The quantity of MUFA content was also affected by the varying drying practices implemented with 10.95% and 7.12% MUFA in solar dried and open sun dried raisins respectively. The drying technique also affects the bacterial load on raisins as observed in our current study with negligible bacterial growth on on solar dried raisins compared to open dried ones.
太阳能干燥机技术简单,由于其简单性,可以在家庭和小型社区中实施。吸收体/集热器的合理设计对于任何太阳能干燥系统都是至关重要的,因为集热器的效率在决定整个系统的干燥效率中起着关键作用。为了研究所开发的太阳能干燥机的实用性,在设计和开发的太阳能干燥机的干燥室中干燥葡萄,并在开放的阳光下进行比较。在该装置中干燥的葡萄干燥速度更快。营养方面的研究表明,太阳干燥过程保留了葡萄干中的总糖、总蛋白质和总脂等主要营养成分。太阳晒干葡萄干与露天晒干葡萄干的灰分含量比较表明,太阳晒干葡萄干的灰分含量为2.71%,露天晒干葡萄干的灰分含量为1.95%。太阳晒干葡萄干和露天晒干葡萄干的MUFA含量分别为10.95%和7.12%,不同干燥方式对MUFA含量也有影响。干燥技术也会影响葡萄干上的细菌负荷,在我们目前的研究中观察到,与开放式干燥葡萄干相比,太阳能干燥葡萄干上的细菌生长可以忽略不计。

Effect of Thermal Treatments on the Fatty Acids Composition, Antioxidant and Anti-inflammatory Properties of Camel Milk 热处理对骆驼奶脂肪酸组成、抗氧化和抗炎性能的影响
M. Hamouda, A. Sboui, Abir Omrani, M. Dbara, Slah Zaidi, M. Hammadi, T. Khorchani
The present research was conducted to study heat treatment's effect on camel milk’s physicochemical and biological activities. Milk samples were heated at 63°C for 30 minutes, 90°C for 3 minutes, and 100°C for 3 minutes. After heating, the physicochemical: pH, acidity, Fat, Dry matter, proteins, and fatty acids composition as well as the antioxidant and anti-inflammatory activities of all samples were determined. The antioxidant activity of camel milk was evaluated by different assays, including free radical-scavenging activity (DPPH and ABTS) and ferric-reducing power assay (FRAP). Results showed that the heat treatment process increased significantly (p<0.05) the viscosity, total solids, ash, and lactose content. Although, the monounsaturated fatty acids and particularly the oleic acid were significantly decreased after heat treatment. Heat treatment didn’t show any significant effect on antioxidant activities. While a significant increase (p<0.05) was shown after boiling the milk in the anti-inflammatory activity. Therefore, pasteurization could be the greatest heating process to ensure the microbiological safety and the stability of the micronutrients in milk.
本研究旨在研究热处理对骆驼奶理化和生物活性的影响。牛奶样品分别在63°C、90°C和100°C加热30分钟、3分钟。加热后测定各样品的理化性质:pH、酸度、脂肪、干物质、蛋白质、脂肪酸组成及抗氧化、抗炎活性。采用自由基清除活性(DPPH)和ABTS (ABTS)及铁还原力(FRAP)测定法评价驼奶的抗氧化活性。结果表明,热处理工艺显著提高了玉米的粘度、总固形物、灰分和乳糖含量(p<0.05)。但经热处理后,单不饱和脂肪酸,尤其是油酸含量明显降低。热处理对其抗氧化活性无显著影响。而煮沸后牛奶的抗炎活性显著升高(p<0.05)。因此,巴氏杀菌是保证牛奶微生物安全性和微量营养素稳定性的最大加热工艺。

Production and Quality Evaluation of Biscuits from Blends of Wheat, Millet and Sesame Seeds Composites: Physical and Sensory Properties 小麦、小米和芝麻复合材料饼干的生产及质量评价:物理和感官特性
Irine Mengeneh, Charles Chukwuma Ariahu
Millet and sesame were processed into flours and mixed with wheat flour at different proportion (100:0:0, 90:5:5, 85:10:5, 80:15:5 and 75:20:5) to produce biscuits. Biscuits produced were analysed for physical properties, and sensory attributes. Sensory evaluation of the biscuits samples was carried out with a team of thirty (30) panellists. The hedonic scale of nine was used, and the panellists were instructed to evaluate the coded samples for appearance, taste, aroma, texture, and Overall acceptability with a reference sample A. Biscuit samples were evaluated for weight (g), diameter (cm), thickness (cm) and spread ratio. Six biscuits edge-to-edge were used for the evaluation and the average was noted. The weight was measured using an electronic scale; diameter and thickness were measured using a Vernier Caliper. The Spread ratio was calculated by dividing diameter by thickness. There was a significant difference in weight, diameter, and spread ratio. Furthermore, there was a general decrease in the weight of the biscuits, with values ranging from 10.950g to 9.600 g with increase in the proportion of millet flour. However, there was an increase in diameter and spread factor as well as a decrease in thickness with increase in millet flour, with values ranging from 4.312 to 4.733 cm, 4.288 to 4.729 and 1.006 to 1.001 cm respectively. The sensory evaluation of the biscuits revealed that there were no significant differences in aroma and taste between the treatments whereas there was a significant difference in appearance, texture and general acceptability. Sensory results showed that all biscuits samples were accepted by panelists.
将小米和芝麻加工成面粉,与小麦粉按不同比例(100:0:0、90:5:5、85:10:5、80:15:5和75:20:5)混合制成饼干。对所生产的饼干的物理特性和感官特性进行了分析。饼干样品的感官评估是由30名小组成员组成的团队进行的。使用9分的快乐量表,并指示小组成员评估编码样本的外观,味道,香气,质地和参考样本a的整体可接受性。饼干样本的重量(g),直径(cm),厚度(cm)和扩散比进行评估。6块饼干边缘到边缘被用于评估,并记录了平均值。重量是用电子秤测量的;用游标卡尺测量直径和厚度。扩散比由直径除以厚度计算。在重量、直径和扩散比上存在显著差异。此外,随着小米粉比例的增加,饼干的重量普遍下降,从10.950g到9.600 g不等。随着小米粉添加量的增加,籽粒直径增大,籽粒展开系数增大,籽粒厚度减小,分别为4.312 ~ 4.733 cm、4.288 ~ 4.729 cm和1.006 ~ 1.001 cm。对饼干的感官评价表明,两种处理方法在香气和口感上没有显著差异,而在外观、质地和总体可接受性上有显著差异。感官测试结果显示,所有饼干样品均被小组成员接受。

Biscuits produced were analysed for physical properties, and sensory attributes. Sensory evaluation of the biscuits samples was carried out with a team of thirty (30) panellists. The hedonic scale of nine was used, and the panellists were instructed to evaluate the coded samples for appearance, taste, aroma, texture, and Overall acceptability with a reference sample A. Biscuit samples were evaluated for weight (g), diameter (cm), thickness (cm) and spread ratio. Six biscuits edge-to-edge were used for the evaluation and the average was noted. The weight was measured using an electronic scale; diameter and thickness were measured using a Vernier Caliper. The Spread ratio was calculated by dividing diameter by thickness. There was a significant difference in weight, diameter, and spread ratio. Furthermore, there was a general decrease in the weight of the biscuits, with values ranging from 10.950g to 9.600 g with increase in the proportion of millet flour. However, there was an increase in diameter and spread factor as well as a decrease in thickness with increase in millet flour, with values ranging from 4.312 to 4.733 cm, 4.288 to 4.729 and 1.006 to 1.001 cm respectively. The sensory evaluation of the biscuits revealed that there were no significant differences in aroma and taste between the treatments whereas there was a significant difference in appearance, texture and general acceptability. Sensory results showed that all biscuits samples were accepted by panelists.","PeriodicalId":23662,"journal":{"name":"World Academy of Science, Engineering and Technology, International Journal of Nutrition and Food Engineering","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84497640","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}
