Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh lama fermentasi moromi terhadapviskositas, kadar protein terlarut, aktivitas antioksidan, dan sensori dari kecap bungkil wijen putih sangrai dannonsangrai, dan untuk mengetahui perlakuan yang menghasilkan kecap dengan kualitas terbaik dari parameterpengujian yang dilakukan. Perancangan Penelitian menggunakan Rancangan Acak Lengkap (RAL) yaitu lamafermentasi 0, 2, 4, 6, dan 8 minggu kecap bungkil wijen putih sangrai dan nonsangrai. Hasil penelitianmenunjukkan bahwa pengaruh lama fermentasi moromi dari 0 sampai 8 minggu memberikan perbedaan yangnyata pada 5% terhadap viskositas, kadar protein, antioksidan kecap bungkil wijen sangrai dannonsangrai. Namun untuk sensori tidak begitu memberikan perbedaan yang nyata. Hasil yang didapat viskositasterbesar pada fermentasi 4 minggu sebesar 977 cP, kadar protein terlarut pada fermentasi 6 minggu sebesar 3,03% dan 2,97 %, aktivitas antioksidan pada fermentasi moromi 6 minggu sebesar 6,96%/mg dan 6,02%/mg.Perlakuan lama fermentasi moromi 6 minggu dipilih sebagai perlakuan lama fermentasi moromi yangmenghasilkan kecap yang terbaik. Untuk perlakuan penyangraian, pada penelitian ini memberikan pengaruh,dimana pada kecap bungkil wijen putih sangrai memberikan viskositas, dan aktivitas antioksidan yang lebihtinggi dibandingkan tanpa penyangraian

Abstract

Tujuan dari penelitian ini untuk mengetahui pengaruh konsentrasi tepung uwi putih kulit cokelat terhadap nilai pH, viskositas, kadar asam laktat, karakteristik sensori, dan total bakteri probiotik pada minuman sinbiotik uwi putih kulit cokelat. Penelitian ini terdiri dari dua tahap utama yaitu pembutatan tepung uwi putih kulit cokelat dan pembuatan minuman sinbiotik uwi putih kulit cokelat. Rancangan percobaan adalah Rancangan Acak Lengkap (RAL) dengan satu faktor yaitu kombinasi tepung uwi putih kulit cokelat. Untuk melihat beda nyata antar perlakuan dianalisis secara statistik menggunakan oneway ANOVA pada taraf α 0,05 dilanjutkan dengan menggunakan uji Duncan Multiple Range Test (DMRT) pada taraf α 0,05. Perbedaan konsentrasi tepung uwi putih kulit cokelat memberikan pengaruh yang berbeda terhadap nilai pH, nilai viskositas, kadar asam laktat, nilai sensori, dan total bakteri probiotik. Nilai pH terendah (3,68), kadar asam laktat tertinggi (0,60%), dan total bakteri probiotik terbesar (9,39 log cfu/ml) didapatkan dari penambahan 2,5% tepung uwi putih kulit cokelat dan 7,5% susu skim. Nilai viskositas terbesar didapatkan dari penambahan 10% tepung uwi putih kulit cokelat dan 0% susu skim yaitu 10,92mPas. Berdasarkan analisis sensori penambahan tepung uwi putih kulit cokelat 7,5% dan susu skim 2,5% memiliki nilai sensori paling baik diantara keempat sampel lainnya berdasarkan parameter warna (2,78), kekentalan (2,41) dan overall (2,85).

Abstract

Curing is a method that can be used to maintain the quality of beef. The curing method uses nitrate and nitrite compounds, which have useful roles in the curing process. However, those compounds have a side effect on the body if consumed continuously, which causes cancer disease (carcinogenic). This harmful carcinogenic property can be controlled by the addition of ascorbic acid. Ascorbic acid is commonly found in several fruits, one of which is red guava (Psidium guajava L). Therefore, this study aims to find out the most optimal addition of red guava extract in maintaining the beef qualities with curing treatment on the parameters of water content, pH, whc, texture, color, ascorbic acid, and nitrite residue. This study was conducted using a Completely Randomized Design with the various concentration of red guava extract (0%-5%) and observed at soaking times of 0, 2, 4, and 6 days. The analysis was performed by twice of sample repetition and analysis repetition. The results of the analysis were statistically analyzed by One Way ANOVA continued with the DMRT test if the results were significantly different (α = 0.05). Based on the results of the study, the higher of concentration in red guava extract, the pH, water content, whc, b* color, a* color, nitrite residue were smaller while the hardness, springiness, cohesiveness, L* color, a* color, the ascorbic acid content in curing were higher. The chosen treatment due to the test parameter in this study was the addition of 4% concentration in red guava extract in the curing process with 2 days soaking times.

Abstract

Pasteurized milk stored at cool temperatures generally have a relatively short shelf life. Antibacterialactivity of noni juice in maintaining the quality of pasteurized goat's milk stored at cold temperatures wasinvestigated. Characteristics of pasteurized goat's milk examined were organoleptic performances, microbialgrowth (total plate count and psychotrophic bacteria), chemical characteristics (protein, pH and acid total) withthe addition of noni juice at variation concentrations) (0%, 5%, 7.5%, 10%, and 12.5%) and times of storage(0.5, 10, 15 and 20 storage days). The results showed that the concentration of noni juice addition of 0 % -7.5 %on the parameters of colour, flavour, taste and homogenity and still were acceptable by consumers. Theinhibitory effects of TPC amount of growth were shown in 12.5% (2.8x101-3.3x101cfu/ml), and this inhibitoryeffects weren’t significantly different between each other of concentrations) (α> 0.05). The low decrease ofprotein content was indicated at concentrations of 7.5 % and still with the value of under SNI up to 20 days ofstorage (from 3.48 to 3.19%). The lowest decrease of pH and the increase acid total titration were shown atconcentrations of 5% with the values of pH (6.40 to 6.17) and acid total (0.20 %-0.22%). Based on organoleptic,microbial and chemical characteristics, it can be concluded that the best concentration of noni juice than that theothers can be added to the pasteurized goat milk during storage was 5%.

Abstract

The urgency of biodegradable packaging as an alternative for plastic-based packaging has been demanding. Accordingly, in this study, the development of pectin-based edible coating incorporated with lemongrass essential oils (LEO) has been done to sustain the physicochemical quality of papaya. The edible coating was prepared by using a simple solution method, while LEO was produced by using the water vapor distillation method. Basically, there are five applied treatments, which are uncoating (control), dip-coating (DC), spray-coating (SC), dip-coating with LEO introduction (DC/LEO1%), and spray-coating LEO incorporation (SC/LEO1%). The physicochemical characteristics of papaya were examined over 12 days of storage. Compared to the control, the application of edible coating was significantly (p < 0.05) enhanced weight loss, pH, ascorbic acid, and yeast and mold counts. Therefore, by mixing pectin-based coating solution with LEO can preserve the quality of papaya for almost more than 12 days at room temperature.

Abstract

Patin is a type of fish commonly processed into fillets for export purposes. Patin fillets are prone to deterioration during cold storage. Nisin is a natural preservative that inhibits microbial growth, particularly Gram-positive bacteria; however, it remains ineffective against Gram-negative bacteria. A combination of nisin and chitosan has been reported to inhibit Gram-negative bacteria. This study aimed to analyze the effect of combining nisin from Lactococcus lactis subsp. lactis and chitosan, applied by bottle-spraying, on the quality parameters (total plate count/TPC, pH, total volatile base nitrogen/TVB-N, and thiobarbituric acid/TBA) of patin fillets during cold storage (4±1 °C) for 16 days. The treatments consisted of 2% chitosan, combinations of nisin–chitosan (125 IU ml-1 nisin and 1.5% chitosan, 250 IU ml-1 nisin and 1% chitosan, 500 IU ml-1 nisin and 0.5% chitosan), and 1,000 IU ml-1 nisin. The results showed that both the combined treatments of nisin and chitosan, as well as the individual applications of 1,000 IU ml-1 nisin and 2% chitosan, slowed the increase in TVB-N and TBA values. However, these treatments did not significantly affect pH or microbiological quality (TPC). The combination treatment effectively delayed chemical spoilage (TVB-N, TBA) during cold storage; however, microbial limits (TPC) were reached by day 12, indicating that the overall shelf life of patin fillets could not be extended beyond this period.
