Development and evaluation of low-fat ready-made dishes prepared by the sous vide process from hybrid sorubim fillets by using different treatments

The aim of this work was to develop and evaluate ready-made dishes of hybrid sorubim fish fillets obtained by the sous vide process. Three treatments were investigated: T1 with brine containing fine-herbs, T2 with brine containing fine-herbs, olive oil, and rosemary; and T3 with the same brine as in T1 but added of 30% of tomato sauce. Results showed the protein content increased according to the type of liquid medium employed, where the lowest value was determined for T1 and the highest value for T3. The sous vide process did not influence the lipid and protein contents of the treatments, be by the addition of olive oil (T2) nor by tomato sauce (T3). Treatments differed for all sensory attributes and presented acceptability indexes above 78.66%. indicating that they are good alternatives for fish consumption. However, T1 had the highest percentage of purchase intention (97.23%), representing the best product for commercialization.

The Dangau Datuk Bengkulu Agribusiness Vocational Middle School has practicum facilities for cultivating various types of vegetables, one of which is tomatoes, which are sold directly at outlets provided to meet the daily needs of students. However, the characteristics of agricultural products are not durable,perishable, and rotten if they are not immediately sold. This problem has attracted the interest of proposers to help introduce value added analysis through processing tomatoes into tomato sauce which of course can lasta long time, have added value and high selling value. Students and some teachers have received value-added introduction training through sauce processing, operational management, training on determining the cost ofgoods sold (HPP). The ratio of added value from processing tomatoes into tomato sauce is obtained by 40% and the added value is obtained by subtracting the output value from other input prices and the raw materialprice of Rp. 6,666.67, meaning that every 1 kg of tomatoes costs Rp. creating added value of Rp. 6,666.67, - per Kg after being processed into tomato sauce.

Community Empowerment through Agricultural Commodity Processing Training as an Effort to Improve Community Welfare in Kerta Barat Village, East Java

Kerta Barat Village in Dasuk District is one of several tomato and chili producing areas in Sumenep Regency. The economic potential of processed food production from agricultural commodities is considerable. This potential can be further increased by harvest abundance. Tomatoes and cayenne chillies are categorized as agricultural commodities with a shelf life and are difficult to store for long periods. The best solution to the overabundance of crop products is by processing these agricultural materials into processed products capable of extended periods of storage. Additionally, processed food products will add to the economic value of the commodity itself. This community service aims to empower the people of Kerta Barat Village by exploiting the potential of agricultural commodities through the processing of tomato sauce and cayenne chilli powder products. This activity was carried out through training and mentoring on the subject of food product processing of tomato sauce and cayenne chili powder. Knowledge and skill increase were seen to have followed this empowerment activity, namely partners can process tomato and cayenne chilly commodities into tomato sauce and cayenne chili powder products through the use of simple technology. A social impact was perceived where partners have become acquainted with agricultural commodity processing technology, namely for the process of drying and size reduction in the manufacturing of processed tomato and cayenne chili products. Additionally, the utilization of post-harvest technologies is crucial for the process of making produced commodities more useful and increase its economic value, which in turn can lead to welfare for the locals.

Effect of a novel functional tomato sauce (OsteoCol) from vine-ripened tomatoes on serum lipids in individuals with common hypercholesterolemia: tomato sauce and hypercholesterolemia

Background Most studies focused on the benefits of lycopene on serum lipids but no studies have been specifically designed to assess the role of a tomato sauce from vine-ripened tomatoes on patients affected by polygenic hypercholesterolemia. The aim of this study was to compare the lipid-lowering effect of a novel functional tomato sauce with a well-known functional food with a lipid-lowering effect, i.e. a sterol-enriched yogurt. Methods In this cross-over study, we evaluated a population of 108 ambulatory patients affected by polygenic hypercholesterolemia of both gender, who were allocated to a tomato sauce (namely OsteoCol) 150 ml/day or a sterol-enriched yogurt (containing sterols 1.6 g/die) treatment, for 6 weeks. Carotenoids content was 3.5 mg per gram of product. We measured serum lipids and creatinine and transaminases at basal and follow-up visit. Results A total of 91 subjects completed the protocol. A significant difference in LDL-cholesterol change was found between participants taking yogurt, tomato sauce (high adherence) and tomato sauce (low adherence) (− 16; − 12; + 8 mg/dl respectively; p < 0.001). We found a greater LDL-cholesterol reduction in the participants with a basal LDL-cholesterol more than 152 mg/dl (15% for sterol-enriched yogurt and 12% for tomato sauce at high adherence). Conclusion A novel functional tomato sauce from vine-ripened tomatoes compares favourably with a commercialised sterol-enriched yogurt in term of absolute LDL-cholesterol change. Intake of a tomato sauce with a high carotenoid content may support treatment of patients affected by common hypercholesterolemia. The present study has various limitations. The presence of other dietary components, which may have influenced the results, cannot be ruled out. Of course, these results cannot be extrapolated to other populations. Furthermore, there was a low adherence rate in the tomato sauce group. Moreover, we did not report serum carotenoids data.

Effects of ingredients and cooking time on total phenolic content and antioxidant activity of different homemade tomato sauces

Tomato is one of the most consumed fruits in the world. Tomato sauce, a tomato product, is one of the mother sauces that has been developed by Escoffier (1846-1935). Nowadays, tomato sauce has been adapted by each country according to their own culinary culture. In the current study four different tomato sauce recipes were investigated in the context of their antioxidant activity and total phenolic content. Hydrophilic and lipophilic extractions of samples were evaluated separately. It was found that there is a relationship between total phenolic content and antioxidant activity in hydrophilic extraction. However, no similar correlation was found between total phenolic content and antioxidant activity in lipophilic extraction. According to the results, the highest antioxidant activity of both hydrophilic and lipophilic extractions was observed in S1 with the values 25.53±1.01 and 45.48±2.06 respectively. In lipophilic extraction, S2 had the lowest antioxidant activity with 32.77±1.07, because of the lack of the ingredients high in lipophilic antioxidant compounds. It was observed that the shortest cooking time with 10 min provide the highest retention of antioxidant activity and total phenolic content in this sauce. Also, antioxidant activity of lipophilic extraction for longer cooking time applied sauces (S4) could be kept high with ingredients such as carrot. It can be suggested that adding of ingredients which have antioxidant activity may be useful for providing bioactive properties in long cooking time procedures and it should be noted that the length of cooking time negatively affected the TPC values.

Kinetic Study of Water and Total Soluble Solid Changes of Black Cherry Tomato (Solanum Lycopersicum cv. OG) Sauce using Rotary Vacuum Evaporation

Kinetics of water removal and total soluble solid (TSS) content change of black cherry tomato (cv. OG) sauce by rotary vacuum evaporation (RVE) were investigated. The effect of different vacuum conditions (vacuum levels and boiling temperatures of 500 mmHg - 80oC, 550 mmHg - 75oC, 600 mmHg - 70oC and 650 mmHg - 65oC) during evaporation /concentration was examined. Tomatoes puree with an initial TSS of 13.47±0.18oBrix was concentrated to 39.83±0.30oBrix. There was a linear relationship between water removal and time during the concentration of black cherry tomato sauce by RVE. The TSS change of tomato sauce during the concentration was applied to three exponential mathematical models (two-parameter, three-parameter, and four-parameter). In studying the consistency of all models, some statistical indicators, namely the coefficient of determination (R2), the chi-square (χ2) as well as the root mean square error (RMSE) were considered. Among the models, the three-parameter exponential model was proven to best describe the concentration behavior of the tomato sauce using rotary vacuum evaporation with the highest R2, the lowest χ2, and the lowest RMSE. The validation with the experimental data at other vacuum levels had also confirmed the consistency of the selected model. This knowledge is very important for process optimization and product quality improvement.

Halal Consumption as Ethical Practice: Negotiating Halal Certification in South Africa

In recent decades, the halal certification logo has emerged as a global phenomenon. Halal certification is an attempt to produce a new discursive and material basis for the practice of halal. Halal is extended into new places and products. In South Africa Muslim consumers now query the halal status of tomato sauce, bottled water and even food consumed at the homes of friends and family. Certification is a technology of halal whereby consumers self-regulate practice in new ways. However, the transformations of halal certification have not been complete. Documentary inspection and molecular investigation linked to new kinds of information and new technology have not necessarily eclipsed the importance of intra-Muslim trade, niyya (orientation/intention) and trust for the practice of halal. This paper considers the narratives and practices of middle-class Muslims in South Africa towards an understanding of the complex ways in which halal is practiced and transformed.
