Abstract

ABSTRACT Virgin Coconut Oil (VCO) is coconut oil that is processed by controlled heating or can be produced without heating (fermentation) so that it does not change the composition or aracteristics of the oil. The purpose of this study was to determine the effect of fermentation time on the physical and chemical properties of VCO. This research includes two stages. The first stage is producing VCO based on fermentation time with raw materials such as coconut and tempeh yeast. The second stage performs physical and chemical analysis which includes yield, water content, free fatty acid content and density. This study used a Simple Completely Randomized Design with 1 fermentation time factor (L). There are 4 fermentation times used, namely L1 = 24 hours, L2 = 36 hours, L3 = 48 hours, L4 = 60 hours with 4 replications to obtain 16 experimental units. Further test using DMRT. The results showed that all yields were above 16%. Fermentation time significantly affected the yield, water content, free fatty acid content but had no effect on density. The best results were shown in VCO with 48 hours of fermentation time, namely yield of 21,843%, water content of 0,238%, free fatty acid content of 0,149% and density of 0,892 g/ml. ABSTRAK Virgin Coconut Oil (VCO) adalah minyak kelapa yang diproses dengan pemanasan yang terkontrol atau dapat dihasilkan tanpa pemanasan (fermentasi) sehingga tidak mengubah komposisi atau karakteristik minyak. Tujuan penelitian ini adalah mengetahui pengaruh waktu fermentasi terhadap sifat fisik dan kimia pada pembuatan VCO. Penelitian ini meliputi dua tahapan. Tahap pertama memproduksi VCO berdasarkan waktu fermentasi dengan bahan baku berupa kelapa dan ragi tempe. Tahap kedua melakukan analisis fisik dan kimiawi yang meliputi rendemen, kadar air, kadar asam lemak bebas dan densitas. Penelitian ini menggunakan Rancangan penelitian Acak Lengkap sederhana dengan 1 faktor waktu fermentasi (L). Waktu fermentasi yang digunakan ada 4 yaitu L1 = 24 jam, L2 = 36 jam, L3 = 48 jam, L4 = 60 jam dengan 4 ulangan sehingga diperoleh 16 unit percobaan. Uji lanjut menggunakan DMRT. Hasil penelitian menunjukkan semua rendemen diatas 16%. Waktu fermentasi berpengaruh nyata terhadap rendemen, kadar air, kadar asam lemak bebas namun tidak berpengaruh terhadap densitas. Hasil terbaik ditunjukkan pada VCO dengan perlakuan waktu fermentasi 48 jam, yaitu rendemen 21,843%, kadar air 0,238%, kadar asam lemak bebas 0,149% dan densitas 0,892 g/ml.

Abstract

The bacteria presence in the gastrointestinal tract is one of the important factors determining the support for body health among others. Therefore, it is essential to maintain a population balance, possibly achieved by consuming local probiotic-based sinbiotic yoghurt. The purpose of this study, therefore, was to evaluate the effectiveness of purple sweet potato extracts and local probiotics supplemented in yogurt by a healthy profile. Furthermore, the Health parameters evaluated include gastrointestinal (faecal water), hematology (number of erythosit, leukocyte, hemoglobin and hemtocrit) and immune system (antibody titer) in Spraque dawley albino mice. This study was performed using a Completely Randomized Design on 30 rats divided into 6 groups.  Therefore, those in group K- were administered distilled water from day 1st -21st, YTP =  yogurt without probiotics from day 1st -21st, YDP = probiotic yogurt from day  1st- 21st,  YTP+E = yogurt without probiotic from day 1st- 21st, interspersed EPEC on day 8th – 14th, YDP+E = yogurt from day1st- 21st, interspersed EPEC on day  8th-14th, K + = water from day 1st- 21persed EPEC on day 8th – 14th, YDP+E = probiotic yogurt from day1st- 21st, then fed EPEC on day 8th- 14th. The results showed the effectiveness of probiotic yogurt treatment with purple sweet potato extract supplementation in healthy gastrointestinal (faecal water), hematology (number of erythrocyte, leukocyte, hemoglobin and hematocrit) and immune system (titre antibodies). This phenomenon results from infection by EPEC (Enteropathogenic Eshericchia coli), which is responsible for diarrhea. Furthermore, the YDP treatment possessed a water content characterized by 48.42% feces, while the number of erythrocytes, leucocytes, haemoglobin and hematocrit were 8,58x106/μl, 14,15 x106/μl, 13.98 g/dL and 47,67 mL%, respectively. Moreover, 6,42 log of antibody titers was also determined.

Abstract

The purpose of this study was to determine the antioxidant activity of fermented tea (black tea) with Ketapang leaves (Terminalia catappa) using two variations of leaf age, namely leaflets 1-3 and 4-5. The parameters observed were water content, pH, antioxidant activity (IC 50) and total phenol content of tea. Results showed that the antioxidant activity of young leaves (shoots 1-3) significantly higher than old leaves (shoots 4-5) but had lower total phenol and pH. In general, the character of Ketapang leaf tea products at shoots 1-5 has water content ranging from 5.55-5.58%, total phenol content of 22.63-28.97 mg / g EAG, and antioxidant activity (IC 50) of 6.27-6 .71 µg/ml and the pH of steeping water from 5.9 to 6.1.

Abstract

Synbiotic yogurt with purple sweet potato extract supplementation as prebiotics and Lactobacillus plantarum Dad 13 isolated from buttermilk as probiotics has potential as functional food, but requires low storage temperatures. The freeze drying technique requires cryoprotectant as a protective material for products such as yogurt. The purpose of this study was to determine the effect of sucrose concentration on the level of viability of  Lactic Acid Bacteria and Lactobacillus plantarum. This study used a Completely Randomized Design with one factor : concentration of sucrose as cryoprotectant: 0%, 2.5%, 5%, 7.5%, and was carried out in three replications. The results showed that the concentration of sucrose significantly affected the yield of freeze dried synbiotic yogurt, total Lactic Acid Bacteria (LAB) after freeze drying, and total Lactobacillus plantarum before and after freeze drying, but did not significantly total amount of LAB before freeze drying. The best treatment, shown in frozen dried synbiotic yogurt with a sucrose cryoprotectant concentration of 5%. The treatment has the following characteristics: yield, 14.797%, total Lactic Acid Bacteria  1.98x 109 CFU / ml before freeze drying, 9.28x 108 CFU / ml after freeze drying, total Lactobacillus plantarum 8.23 x 108 CFU / ml before freeze drying and 6.81 x 108 CFU / ml after freeze drying.

Abstract

Herbal teas come from other than tea plant (Camelia sinensis). Among the plants that can be used to make tea are ketapang leaves. Efforts are needed to combine with other leaves to make the product more acceptable to consumers. The study aimed to determine the chemical and organoleptic properties of ketapang herbal leaf tea varied by adding mint leaf powder. The stages of the research included making ketapang leaf powder, mixing the ingredients according to the treatment, and testing the tea powder. Tests consist of testing chemical properties (moisture content, ash content, total phenolic, and antioxidant activity) and organoleptic properties (color, taste, and aroma). A completely randomized design (CRD) unidirectional pattern was used in this experiment. The treatment variable was the addition of mint leaf powder with a concentration of 0%, 1%, 2%, 3%, 4%. Analysis of Variance (ANOVA) with a significance level of 0.05 was used to analyze the data obtained. Further tests with the Duncan Multi Range Test (DMRT) were carried out if significant differences were found. The results showed that the water content of ketapang leaf herbal tea powder combined with mint leaf powder was not significantly affected by variations in the added mint leaf powder. However, the ash content had a significant effect. Adding mint leaf powder also significantly affected the antioxidant activity, total phenolics, and organoleptic properties (color, taste, and aroma) of steeping ketapang leaf herbal tea. The total phenolic content and antioxidant activity decreased with the addition of mint leaf powder. The higher the concentration of mint leaf powder added to the ketapang leaf powder, the lower the antioxidant activity. However, adding mint leaf powder up to 4% could increase panelist acceptance of the taste and aroma of ketapang herbal leaf tea.
