The Change in pH on Lactobacillus acidophillus Medium Containing D-fructose Widia Pangetika; Ahmad Ni'matullah Al-Baarri; Anang Mohamad Legowo

This study aims to analyse the pH value on Lactobacillus acidophilus medium containing 3% (w/v) D-fructose. L. acidophilus was incubated at 37°C using MRS agar medium. Changes in pH values were measured for 48 hours. The non-sugar addition was also used as a comparison. Based on this research it could be seen that D-fructose slightly decreased pH in the medium at 48 hour incubation. This research might be useful to provide information on the potential use of D-fructose as a medium to maintain the reduction in pH.

Dekke mas na niura is a typical local food of North Sumatra made from carp which does not undergo cooking processes such as frying, steaming, burning, or boiling but is only paraded. This study aimed to estimate the shelf life of pasta spices using the Arrhenius equation model Accelerated Shelf Life Test (ASLT). This research was conducted at the Laboratory of Food Chemistry and Nutrition, Faculty of Animal Husbandry and Agriculture, Diponegoro University, Semarang. The materials used in making spices dekke mas na niura were andaliman, pecan, turmeric, kecombrang / rias, onion, garlic, salt, red chili, lime, kaffir lime, galangal, and peanuts. The method used for making pasta spices is by mixing spices and grinding ingredients until smooth. Spices are stored at 25°C, 30°C, 35°C and 40°C for 24 hours of storage. The Analysis is carried out every 6 hours. The parameters tested were Aw value, pH value, and total bacteria (TPC). The results of the test data were then made linear regression with the making of ordes 0 and orde 1, then from the data, the shelf life calculation was done with the Arrhenius equation. The results showed that the highest Aw, pH, and total bacterial values were at 40°C which were stored for 24 hours. The critical point used in estimating shelf life was total bacterial orde 1. Estimation of shelf life based on total bacteria was 5.6 days (25°C); 7.1 days (30°C); 5.6 days (35°C); and 5.2 days (40°C). Storage of pasta ingredients dekke mas na niura optimum at 30°C. Overall, the higher the storage temperature and storage time, the shorter the shelf life.

Protein Content in Snake Fruit Cultivar Pondoh (Salacca edulis Reinw.) with Aseptic Condition in Room Storage Yulian Dwi Anggraeni Puspa Handoko; Ahmad Ni'matullah Al-Baarri; Anang Mohamad Legowo; Mulyana Hadipernata; Wisnu Broto

Snake fruit is a type of tropical fruit with high market demand, however it is easily damaged and approximately ± 7 days at room temperature of shelf life. After 3 days of harvest, quality of snake fruit has decrease in chemical components, such as color, hardness, and proximate. The decline in the quality may also be caused by microbial contamination. This study aimed to determine the protein content of snake fruit during storage at room temperature under aseptic condition. This study was done in storage temperature of 25±5ºC and carried out at 3 times repetition. The protein content of snake fruit was observed for 3 days. The results showed that protein content of snake fruit at the beginning of storage were about 0.5%. Then, the protein content decreased until undetectable by the Kjeldahl method on the third day of storage. As conclusion, the three days of decrease in the protein content could be determined.

Inhibition Test of Browning Reaction in Apple (Malus domestica Borkh.) by Low NaCl Concentration Maulana Yusuf; Anang Mohamad Legowo; Ahmad Ni'matullah Al-Baarri

Reaction of enzymatic browning in fruit is a reaction that occurs due to the oxidation of phenol and involves the enzyme polyphenol oxidase (PPO). Prevention of browning reactions can be done by inhibiting PPO activity, one of alternative is to use NaCl. The purpose of this study was to determine the ability of low NaCl concentration to inhibit the browning reaction based on the color change of L* value. Apple peels was dipped in phosphate buffer pH 7.0 containing 0.1 M NaCl and incubated at room temperature for 6 hours. The result indicated the hindrance of NaCl in the development browning color that was detected by L* value. In conclusion, NaCl may inhibit the process of browning apple in room temperature.

Lactobacillus plantarum Dad-13 is an indigenous probiotic that was isolated from Dadih. Peanut chocolate jam has the potential to be developed into a probiotic food product. However, peanut chocolate jam involves a heating process which can affect the number of probiotics and their metabolic processes. This research aims to determine the optimal temperature of L. plantarum Dad-13 probiotic powder in addition to peanut chocolate jam products. The different temperatures of probiotic powder L. plantarum Dad-13 addition at 30 oC, 40 oC, 50 oC, and 60 oC were used to measure total lactic acid bacteria (LAB), sublethal injury, pH value, and total acids. Total lactic acid bacteria and sublethal injury were measured by Total Plate Count (TPC), pH value was measured by pH meter and total acids were analyzed using the titration method. Results show significant differences (p<0,05) on total lactic acid bacteria (LAB) and sublethal injury. Total lactic acid bacteria (LAB) resulting in a value of 8.04±0.02 to 7.67±0.05 and sublethal injury 0.04±0.01 to 0.26±0.03. Meanwhile, no significant differences (p>0,05) in pH value (7.20±0.16 to 7.30±0.15) and total acids (0.09±0.01 to 0.08±0.01). The best temperature of L. plantarum Dad-13 probiotic powder addition on peanut chocolate jam was at 30–40 oC because it showed the highest amount of total lactic acid bacteria (LAB) and the least sublethal injury.

Probiotics are beneficial bacteria found in probiotic products that can maintain the balance of microflora in the gut. Peanut chocolate jam has the potential to be developed into a probiotic food product. However, the shelf life of this product has not been determined so it is necessary to determine the shelf life using the Accelerated Shelf Life Testing method. This method uses the Arrhenius approach. Determination of shelf life through the calculation of total lactic acid bacteria, aw value, pH value, and total acid during storage. The storage of probiotic peanut chocolate jam used three temperature treatments: 4 ℃, 30 ℃, and 37 ℃. Observations of samples stored at 4 ℃ were made every 5 days until day 25, while samples at 30 ℃ and 37 ℃ were made every 3 days until day 15. The data were analyzed using Microsoft Excel 2016 through the presentation of data in the form of a scatter diagram accompanied by a trendline and then described descriptively. The shelf life of probiotic peanut chocolate jam based on best before stored at 4 ℃, 30 ℃, and 37 ℃ were 49.52 days; 10.98 days; and 7.64 days, respectively. The jam can still be consumed up to 255.29 days; 86.73; and 66.89 days but no longer has the benefits of the probiotics.
