Abstract

Yoghurt is a milk product that lactic acid bacteria have fermented. Soyghurt drinks have gained popularity in recent years. Soyghurt is a fermented soymilk drink that tastes similar to yoghurt. Commercial starter cultures or back-sloping methods can make yoghurt and soyghurt. The purpose of this study was to compare the pH and sensory characteristics of yoghurt and soyghurt made using different production methods. Back-slope yoghurt, commercial yoghurt starter, back-slope soyghurt, and commercial starter soyghurt were the four treatments used in this study. The fermentation process was carried out at room temperature (27-30 °C) for 24 hours. Color, aroma, taste, and texture were all measured, as well as the pH value. The sample shows the product has a pH value between 4 and 5. The low pH value in yoghurt and soyghurt is due to the growth of lactic acid bacteria. Based on sensory analysis, commercial starter culture produced the best yoghurt and soyghurt rather than the back-slope method in sensory attributes of taste, aroma, and texture. In addition, the color of soyghurt products appeared to be darker than yoghurt products.

Abstract

Siomay is a snack made mostly from fish, tapioca flour and other spices by steaming. People are interested in siomay because the price is relatively cheap, tastes good, is easy and practical to consume. However, siomay are susceptible to contamination by various pathogenic bacteria because they are sold freely without paying attention to the cleanliness of the seller's environment. In addition, unhygienic management can cause contaminants such as Staphylococcus aureus which can cause health problems. The purpose of this research was to determine the extent of TPC and Staphylococcus aureus contamination and to determine the relationship between chemical properties and microbial growth in siomay sold in Bandar Lampung City. The results showed that all siomay samples exceeded the maximum TPC and Staphylococcus aureus limits set by SNI. According to SNI 7756-2013 concerning siomay the maximum of TPC and Staphylococcus aureus in siomay is 5 x 104 CFU/mL and 1 x 102 CFU/mL respectively.The results of chemical and microbiological correlation tests show that water activity has a correlation with ALT and Staphylococcus aureus, pH has a correlation with Staphylococcus aureus, while aw has no correlation with ALT and Staphylococcus aureus.

Abstract

Fish is one of the perishable food commodities caused by enzyme activity. The activity of microorganisms present in the body of fish or due to the process of oxidation of body fat through the air. The fermentation process is one way to extend shelf life. The fermentation process in fish can be done with the addition of preservatives such as picung. Picung seeds contain tannins and phenols which are antimicrobial compounds. The addition of picung seeds to fish can also help the growth of lactic acid bacteria if stored in a closed container because picung seeds contain carbohydrates, where sugar is converted into lactic acid. This study used quantitative descriptive methods and focused on the effect of variations in picung concentration (30%, 60% and 90%) as well as storage duration of 3 and 6 days at room temperature to determine the effect on total BAL, Salmonella, water content and pH. The results of this study showed that the addition of picung seeds and storage duration in tilapia can affect the total BAL, Salmonella, water content and pH, with the highest total BAL on the third day with a 60% picung seed paste concentration of 7,4 log CFU/g, negative Salmonella on day 6, then the moisture content value and pH value decreased until day 6

Abstract

Dimsum is a popular snack made from chicken wrapped in wheat flour dough and cooked by steaming. It is favored by many due to its delicious taste and affordable price. However, dimsum sold by street vendors often lacks proper hygiene during processing and presentation, making it prone to microbial contamination. Chicken, as the main ingredient, is high in protein, which supports microbial growth. Contamination of microorganisms in food poses health risks to consumers. This study aims to analyze Total Plate Count (ALT) and Salmonella contamination and examine the correlation between chemical characteristics, such as water content and pH, and microbiological growth in chicken dimsum sold by five vendors in Way Halim District, Bandar Lampung City. The microbiological and chemical data were analyzed descriptively, and Pearson Correlation was used to determine the relationship between chemical characteristics and microbial growth. The results showed that all chicken dimsum samples exceeded the maximum ALT limit, and two samples tested positive for Salmonella. Referring to SNI 7756:2013, the standard for siomay quality and safety is a maximum ALT of 5×104 CFU/g and negative/25 g for Salmonella. The correlation test indicated that water content and pH had a significant relationship with ALT growth. The chicken dimsum sample with the highest ALT was the DC sample (6.31 log CFU/g), while the lowest was the DA sample (5.35 log CFU/g). Salmonella contamination was found in the DC and DE samples.
