Pendugaan Umur Simpan Saus Tomat Homemade Menggunakan Model Arrhenius pada Suhu Penyimpanan Berbeda

Ni Wayan Putu Meikapasa — 2024-07-12

Homemade tomato sauce products have the advantage of having a composition that can be ensured to contain minimal harmful chemicals. However, like other processed products, of course, the product will experience a decrease in quality along with the length of storage time. This study aims to determine changes in the quality of tomato sauce produced on a home scale (homemade ketchup) during one month of storage at storage temperatures of 10^oC, 250^oC, and 350^oC. The method used to predict shelf life is the Arrhenius calculation model, which observes changes in pH, aw, and Total Microbes. The findings showed that the pH of tomato sauce tended to decrease with the length of storage time. The number of microbes increased with the increasing temperature and length of storage. Meanwhile, temperature and length of storage did not affect water activity. However, aw tends to increase with the temperature and length of storage. The results of estimating the shelf life with the Arrhenius model based on the water activity (aw) parameter showed that the shelf life of the sauce was 151.75 days with a quality decline rate of 0.001068/day at a storage temperature of 10^oC; 96.07 days with a quality decline rate of 0.001685/day at a storage temperature of 25^oC and 72.6 days with a quality decline rate of 0.002227/day at a storage temperature of 35^oC. The implications of this study indicate that storage at 10^oC can extend the shelf life of both tomato sauce products, so producers and consumers need to consider the optimal storage temperature based on the results of this study.

Bread is generally made from wheat flour which contains gluten is known to have a negative effect on celiac disease patients, so other alternative ingredients are needed in making gluten-free bread. However, the use of these ingredients has a weakness in ability to retain gas during the proofing process, so a hydrocolloid additive, namely Carboxy methyl cellulose (CMC). The aim of this research is to determine the effect of adding CMC and proofing time on the physical characteristics of gluten-free bread. The research method used was a factorial randomized block design (RBD). Factors used in this research was the CMC concentration (1%, 2%, 3%) and the proofing time (30 and 45 minutes). A total of 6 treatment combinations were repeated 3 times to obtain a total of 18 experimental units. Data analysis took the form of analysis of variance (ANOVA) and further DMRT/BNT tests. The results showed that the addition of CMC and proofing time had a significant effect (p¡0.05) on physical characteristics such as volume development, hardness, and stalling rate. This study shows that the addition of CMC and the right proofing time can improve the physical characteristics of gluten-free white bread This research contributes to finding alternative products for people with celiac disease to get white bread products with good physical qualities.

Karakteristik Organoleptik Brownis Berbahan Tepung Komposit Terigu dan Ubi Jalar Kuning

Mufti Ghaffar — 2024-07-31

Brownis are a cake product that is widely consumed by the public, and is prepared traditionally. Brownis tend to contain unbalanced nutrients. So it is considered a food that has little health benefits. One way to increase the nutritional value of Brownis is to substitute other ingredients that have complete nutritional content, namely yellow sweet potato flour. It is known that yellow sweet potatoes contain carbohydrates, minerals, antioxidants and fiber. This research aims to determine the effect of the percentage of yellow sweet potato on organoleptic test results in terms of color, aroma, taste, texture and appearance. The method used is the hedonic test to determine the level of preference and the best formulation. The hedonic scale uses a score of 1: dislike very much, 2: dislike, 3: neutral, 4: like, and 5: like very much. Formulation of brownie products with substitution percentages for yellow sweet potato, namely 0%, 25% and 50%. Based on the research results, the 25% yellow sweet potato flour substitution formulation was the product most preferred by panelists based on the hedonic value of taste, texture, appearance and color. So it can be concluded that the brownie product with the addition of 25% yellow sweet potato is the best formulation in this study.

Tapai is one of Indonesia’s traditional foods, made from fermented carbohydrate-containing food materials such as cassava and sticky rice. Barley seeds are one of the food materials that are rarely utilized and contain carbohydrates so that they can be used as raw materials in making tape. The purpose of this study was to determine how the pH value, alcohol content and organoleptic quality of barley seed tape can be influenced by variations in yeast concentration and fermentation time during the processing process. The research method used was a complete randomized design (CRD) test with two variables: variations in yeast concentration (0.5 grams, 1.0 gram and 1.5 grams) and fermentation time (24 hours, 48 hours, and 72 hours). The results showed that different yeast concentrations significantly affected the pH value, alcohol content, and organoleptic quality of barley tape. Both pH value and organoleptic quality were significantly affected by the length of fermentation but had no effect on alcohol content. Barley seed tape with a yeast concentration of 0.5 grams and a fermentation time of 48 hours was the treatment combination most favored by panelists and had good tape quality. The research contributes to opening opportunities for diversification of traditional food ingredients that were previously rarely utilized.
