One of the most popular dairy products is cream cheese. This cream cheese has a soft texture, a white color, and a savoury flavour. It can be used as a topping or a complimentary element. This objective of this study was to determine the differences effect in the ratio of bromelain and rennet enzymes on the physicochemical characteristics of cream cheese. The experimental design used in this research was a Completely Randomized Design (CRD) with the following treatments: 8% bromelain enzyme (P1); 8% rennet enzyme (P2); bromelain enzyme 7% + rennet enzyme 1% (P3); bromelain enzyme 4% + rennet enzyme 4% (P4); 1% bromelain enzyme + 7% rennet enzyme (P5) where each treatment will be repeated 3 times. Some of the parameters tested were yield, pH, water content, protein content, color degree and spreadability. Based on the effectiveness test to determine the best treatment, the highest value was obtained for the P4 treatment with a yield of 11.14%, pH value of 5.83, water content of 55.50%, protein content of 5.62%, color degree of 78.21, and spreadability of 3.50 cm.","PeriodicalId":499780,"journal":{"name":"Journal of Tropical Food and Agroindustrial Technology","volume":"66 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141663353","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 temperature methods used include room temperature, high temperature, low temperature and thawing. The color of the meat will change due to the interaction between myoglobin and oxygen which will form metmyoglobin after protein denaturation, so that it can change the color of the meat from reddish to brown and unattractive. When storing meat, it must be well controlled starting from air conditions and humidity so that it can maintain the red color of the meat. Apart from that, storage conditions and temperature control play an important role in storing meat, so that the quality of the meat lasts longer.","PeriodicalId":499780,"journal":{"name":"Journal of Tropical Food and Agroindustrial Technology","volume":"9 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140478849","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}

Beeswax is one of the materials that can be a hardness base that can be applied to food. The use of beeswax in chocolate candy is expected to provide a solution for the cocoa agro-industry. This study aims to determine the effect of different percentages of beeswax on the characteristics of chocolate candy. The design used in this study is a completely randomized design (CRD) with 5 treatments with 3 replications. Observational data were analyzed with variance analysis (ANOVA) if significantly different, DNMRT (Duncan's New Multiple Range Test) was conducted at a real level of 5%. The treatments used were 0%, 5%, 10%, 15%, 20% addition of beeswax percentage to chocolate candy. The results showed that the addition of beeswax percentage had a significant effect on fat, hardness, and organoleptic properties but did not significantly affect the water content of chocolate candy. The physical and chemical values are hardness 209.92 N/cm2, moisture content 1.01%, fat content 44.11%. Meanwhile, the organoleptic test results showed that treatment E was the most desirable product.","PeriodicalId":499780,"journal":{"name":"Journal of Tropical Food and Agroindustrial Technology","volume":"349 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140473587","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 content of active chemical compounds and various chemical properties of coffee are influenced by the area of the coffee is grown, the height of the plantation land, the type of coffee, and the processing process. In this research, a quantitative analysis of the chemical compounds and chemical properties of coffee from various regions in Indonesia was carried out with the aim of determining the caffeine content and acidity level (pH) as well as the total acid contained. This parameter is important to analyze due to it could influence the level of consumer acceptance. The method used in this research is the Completely Randomized Design (CRD) method using one research factor, the origin of the coffee area including Aceh coffee, Papua coffee, Wonosalam coffee, Sidikalang coffee and Ngawi coffee with the parameters observed being caffeine content, pH value and total titrated acid. The results showed that the caffeine content in Arabica Aceh, Excelsa Ngawi, Arabica Papua, Robusta Sidikalang and Excelsa Wonosalam meets the provisions of SNI 01-3542-2004, not more than 2% from 0.2% - 1.78%, the pH of these five coffee regions has significant differences from 5.69-6.55. These pH value has still considered safe for human consumption. Furthermore, the total acid value of these five types of coffee ranges from 0.97 to 1.36, with the total acid value of Sidikalang robusta being different from coffee from other regions.","PeriodicalId":499780,"journal":{"name":"Journal of Tropical Food and Agroindustrial Technology","volume":"28 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139608749","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}
