Abstract

Previous research has identified the food safety aspects of the fresh fruit juices sold in Surakarta. The results showed that the level of microbiological contamination in fresh fruit juice was very high and it was not safe for consumption. This study aims to test the ability of mint leaves (Menta piperita) as a natural antimicrobial source to suppress the growth of pathogens in avocado juice. Mint leaves contain natural antimicrobial compounds in the form of menthol, menthone, menthophuran, and methyl acetate. The study used a factorial completely randomized design with 2 factors, namely the length of incubation time and the addition of mint leaves stored in standard room temperature and refrigerant. The incubation times were 0, 2, 4, and 6 hours. The results showed that mint leaves were able to suppress the number of Staphylococci, reaching the lowest number, namely 2.19 ± 0.00 log CFU / ml. Total Salmonella-Shigella was not detected by adding mint leaves and incubation for 6 hours at cold temperature. The total coliform count gave the final result with the lowest log colony count value in avocado juice and cold incubation temperature of 3.58 ± 0.43. The use of mint leaves as a natural antimicrobial in food is not yet effective, so it needs to be studied more about the use of its essential oil or needs to be explored for further effective methods.

Abstract

Cilok was a traditional food originating from Bandung and comes from the abbreviation of "Aci dicolok". As the name implies, a snack made from tapioca flour mixed with condiment and sometime using meat or fish fillet. It was tasty and chewy. Cilok has quietly different from meatball because meatball using wheat flour. Cilok usually consumed using a sauce made from crushed peanuts, sugars, salt, mixed with chili sauce, tomato sauce, or soy sauce which can be modified as you want. Recently, cilok sales in the city of Surakarta have become increasingly popular. In almost every corner we can find cilok sellers. This study aims to determine the level of microbiological contamination found in cilok and peanut sauce in Surakarta. The research method used was simple random sampling method from 5 districts in Surakarta. The number of contaminants was calculated by the direct plate count method. The tests performed were to determine the total plate count (ALT), total Staphylococci, total Salmonella shigella, and total coliforms of the cilok and also for the sauce. As for the cilok sample, the average log value of ALT was 6.57 - 7.97 log CFU / g, total Staphylococci 4.57 - 4.96 log CFU / g, Salmonella shigella was 0.53 - 1.23 log CFU / g, and total coliforms 1.00 - 2.26 log CFU / g. Peanut sauce sample, the average log value of ALT was 7.40 - 8.18 log CFU / g, total staphylococci 5.84 - 6.68 log CFU / g, total Salmonella shigella was 2.24 - 3.23 log CFU / g, and Escherichia coli 2.35 - 5.79 log CFU / g. From the test results of the peanut sauce and peanut sauce samples, it can be concluded that the peanut sauce and peanut sauce sold in Surakarta are still not suitable for consumption.

Abstract

Fresh fruit juice was processed food was a part of healthy diet. Daily fresh juice consumption could improve health and prevent the occurrence of degenerative disease. Fresh juice were produce without any heat treatment which could allow natural microflora to growth. The aims of the research was to determine the microbiological contaminant of avocado street juice sold in Surakarta. Twenty five of samples were taken from 5 district. Samples were analyze for total viable aerobic count (TVAC), total coliform, total salmonella count, and total staphylococci. The results showed that microbiological contaminant of street avocado juice was extremely high. TVAC of avocado juice was 6.07 ± 0.37 to 8.95 ± 0.04 log CFU/ml; Total coliform 3.28 ± 0.01 to 4,60 ± 0,02 log CFU/ml; Total Staphylococci 4,47 ± 0,07 to 7,35 ± 0,07 log CFU/ml; and Total Salmonella-Shigella 2,34 ± 0,06 to 4,80 ± 0,00 log CFU/ml. There was 1 grocery that produce avocado juice which have undetected for coliform analysis. Producers, government and also consumers need to make some agreement to improve the safety of fresh juice.

Abstract

Pumpkin is an annual plant that is widely available in Indonesia. Pumpkin will quickly spoil and rot if the hard skin is injured. Pumpkin is a type of food that contains high antioxidant activity. To prevent damage to pumpkin, this fruit can be processed into flour. The purpose of this study was to determine the varieties of pumpkin and the most optimal drying temperature to produce pumpkin flour which has the highest antioxidant activity. The study was conducted using a factorial Completely Randomized Design (CRD) consisting of 2 factors. The first factor is the yellow pumpkin varieties, namely machete pumpkin, kabocha pumpkin, and honey pumpkin while the second factor is the drying temperature at 50 ℃, 60 ℃, and 70 ℃ with a drying time of 11 hours. The result showed that Kabocha pumpkin varieties and drying temperature of 60 ℃ produced pumpkin flour with the highest antioxidant activity of 88.05 %. Other chemical characteristics of this pumpkin flour are water content of 13.30 %, beta-carotene 0.16 g/g, total phenol 23.81 mg gallic acid equivalent/g, total sugar 23.55 %, and yield of 10.94 %.
