Abstract

Rambusa (Passiflora foetida L.) adalah tanaman liar merambat yang sering ditemui di daerah seperti rawa dan pinggiran sungai. Daun tanaman rambusa ini mempunyai fungsi alternatif sebagai anti hipertensi dan anti diabetes. Penelitian ini bertujuan membandingkan karakteristik sensoris teh yang dihasilkan dari dua metode handmade yang berbeda, yaitu metode sangrai dan metode blanching. Bahan utama teh menggunakan sampel dari Desa Babulu Darat, Penajam Paser Utara, Kalimantan Timur. Penelitian ini dirancang dalam Rancangan Acak Lengkap untuk membandingkan karakteristik sensoris teh yang dihasilkan dari dua metode handmade. Masing-masing perlakuan dilakukan dengan 6 ulangan. Parameter yang diamati adalah karakteristik keseluruhan sensoris hedonik teh yang dihasilkan meliputi warna, aroma, tekstur untuk teh dan warna, aroma, rasa untuk seduhannya. Skala yang digunakan adalah 1-5 yang menunjukkan sangat tidak suka, tidak suka, agak suka, suka, dan sangat suka. Data dianalisis dengan uji Uji Wilcoxon. Respons sensoris hedonik performance bentuk teh daun rambusa yang dihasilkan dengan metode sangrai secara nyata (p0,05) mendapatkan respons sensoris lebih tinggi tinggi (skor 4, suka) dibanding teh yang dihasilkan dengan metode blanching (skor 3, agak suka). Hasil penelitian menunjukkan bahwa kedua metode tersebut dapat digunakan, tetapi metode sangrai menghasilkan teh dengan sifat sensoris hedonik yang lebih disukai.

Abstract

Dayak tribe, as the native people of Kalimantan, has used the Keluwek plant for generations to prepare food sources of protein such as meat and fish. Apart from getting a preferred taste, this plant has also extended the food shelf life. This research aims to determine the sensory response profile of cooked products from preserved fish using Keluwek leaves. Tilapia fish is preserved using chopped Keluwek leaves for 2 days, then steamed and fried to get the cooked product. The organoleptic properties of fresh fish from preservation were compared with fresh fish without preservation using a quality assessment score of 1-9 based on SNI 01-2729.1-2006 for eyes, body surface mucus, odor, and texture. The cooked product's hedonic organoleptic properties and hedonic quality (color, aroma, taste and texture) were also observed (score 1-5). The results showed that on day 2 of preservation, the sensory properties of preserved fish were significantly different (p0.001) from fish without preservation for the eye, body surface mucus, smell, and texture attribute. Meanwhile, the sensory properties of the steamed cooked product are significantly different (p0.001) from those for the taste attribute but are not significantly different (p0.001) for the color, aroma, and texture attribute. Likewise, the sensory properties of the cooked fried product are significantly different (p0.001) for the color, aroma, taste and texture attribute. The steamed cooked product of preserved tilapia received a neutral response. for the attribute of color, aroma, taste, and texture. Meanwhile, the cooked fried product of preserved tilapia received a bit dislike response for the attribute of color, smell, taste, and a neutral response to texture attribute.Keywords: Keluwek, Nile fish, fish preservation.

Abstract

Crystal palm sugar (CPS) is crystal brown sugar produced from palm tree sap. The quality of CPS depends on the quality/freshness of the sap, while the sap quality depends on the tapping method and its freshness. This study aimed to determine the appropriate sap tapping time of Arenga palm (Arenga pinnata) for raw material in CPS processing. The sap tapping time was carried out at 3, 6, 9, and 12 hours, each with four replications. Sap tapping was done by adding five grams of sodium bicarbonate into the sap container. Parameters observed were sap pH, yield, chemical properties (moisture content, ash content, and reducing sugar content), and sensory properties (color, aroma, texture, and taste) of the CPS. The data were processed by ANOVA and polynomial regression. The results showed that sap tapping time significantly affected (p<0.05) the sap pH and reducing-sugar content of CPS, but not (p>0.05) the yield, water content, ash content, and sensory response of CPS. However, using quadratic polynomial regression shows that CPS yield is optimum by processing the palm sap at about seven hours of tapping time, i.e., 14.56% and 12.47% for coarse and fine CPS, respectively. The sap pH obtained from the seven hours of tapping time was 6.8-7.1. The CPS has a reducing sugar content of 26.94% and overall hedonic characteristics of moderately like. The hedonic quality characteristics of the CPS are typical palm sugar for aroma, slightly brown for color, slightly hard for texture, and sweet for taste.

Abstract

Frangipani flower (Plumeria acuminata) and bitter grape (Tinospora crispa L. Miers) stem extract alone shows antimicrobial and antioxidant activities. However, there is a limited report about the actions from the combination of both extracts. Combinations of ethanol extract of white frangipani flower (EFF) and ethanol extract of the bitter grape stem (EBS), each of 0, 1, 2, and 3% were tested for inhibition against Staphylococcus aureus growth and DPPH (1,1-diphenyl,2-picrylhydrazyl) free radicals. A yield of 3.17 and 2.62 g of EFF and EBS, respectively, were resulted from 100 g of dried powdered of the white frangipani flower and bitter grape stem using 200 mL of absolute ethanol. The antimicrobial test was assayed using a 10% stock solution of extract diluted in water. The combination of EFF and EBS showed a synergistic effect on antimicrobial activity, but it proved an antagonistic effect on antioxidant activity. The combination of EFF 3% and EBS 3% showed the highest inhibition index on the S. aureus growth , i.e. 2.02±0.06, which is higher than the inhibition index of Amoxycillin 2%, i.e. 1.85±0.09. The highest antioxidant activity showed by 1% EFF alone (57.5 ± 0.60%), while the lowest was from the combination of EFF 1% and EBS 3% (23.4±0.30%).

Abstract

Gendarussa (Justicia gendarussa) is a herbaceous plant with a height of 1-1.5 m. Its stem and leaves extract show antimicrobial and antioxidant activities and have potent cytotoxic activity on the human cancer cell. Gendarussa has a better flavor than stem. Its aqueous extract shows higher extract than ethanol extract. The present study evaluated the preservative effect of aqueous extract of gendarussa leaves (GL) in prolonging the shelf life of wet noodles. The single-factor experiment (GL of 0, 50, 100, 150, and 200 g was extracted in hot water of 100 mL) arranged in a completely randomized design was applied in this research. Total bacterial and mold were observed as well as sensory hedonic characteristics during storage. Data were analyzed using SPSS ver.25. The microbial quality data were analyzed by the Kruskal-Wallis test followed by pair comparison with Bonferroni correction, while the sensory data analyzed by Friedman test continued by Wilcoxon Sign Rank Test. The results showed that the addition of GL aqueous extract (200 g in 100 mL hot water) could prolong the shelf life of wet noodles. The microbial quality of the wet noodle, which preserved at room temperature for 24 h still meet the Indonesian standard of wet noodle (SNI: 2987-2015) for total bacteria and 36 h for total molds. The wet noodles have log cfu/g of 5.35 and 1.58 for total bacterial and mold, respectively. The panelists preferred the color, aroma, texture, and taste of wet noodles produced with the GL aqueous extracts. The most preferred one was wet noodle with the addition of GL aqueous extract at a concentration of 200 g per 100 mL with the characteristic of greenish-white color, not scented with GL, chewy texture, and slightly flavored GL.
