Abstract

Minuman fungsional okra memiliki berbagai senyawa yang bermanfaat bagi kesehatan, namun memiliki nilai sensori yang kurang baik sehingga diperlukan adanya penambahan sukralosa dan ekstrak kayu manis. Penelitian bertujuan untuk mengkaji karakteristik minuman fungsional okra dengan penambahan konsentrasi sukralosa dan ekstrak kayu manis yang berbeda. Mutu minuman fungsional ditinjau dari karakteristik fisik, kimia, mikrobiologi, dan organoleptik. Rancangan penelitian yang digunakan yaitu Rancangan Acak Lengkap (RAL Faktorial) dengan dua faktor yaitu konsentrasi sukralosa (0,01%, 0,02%, 0,03%) dan faktor konsentrasi ekstrak kayu manis (10%, 15%, 20%) dengan tiga kali ulangan. Data yang diperoleh dianalisis dengan ANOVA dengan α<0,05 dan uji lanjut DMRT jika perlakuan berbeda nyata. Perlakuan terbaik dari penelitian yakni penambahan konsentrasi sukralosa 0,03% dan ekstrak kayu manis 20%, dengan karakteristik kadar total padatan terlaut sebesar 3,20˚Brix, pH 5,33, kadar keasaman 0,65261%, kadar aktivitas antioksidan IC50 37 ppm (sangat kuat), nilai uji hedonik pada parameter warna dengan rata-rata 4 (suka), aroma 4 (suka), rasa 4 (suka) serta pada pengujian logam berat Pb, Cd, Sn, Hg dan As bernilai di bawah ambang batas, kadar cemaran bakteri Escherichia coli <3 APM/ml, dan sudah sesuai dengan SNI 3719-2014.

Abstract

Tropical citrus fruits contain important bioactive compounds with health-promoting properties such as antioxidant and antibacterial properties. This study provided comparative data on the antioxidant and antimicrobial activity of tropical citrus (local lemons, imported lemons, and limes) juice and peel. Antioxidant activity of citrus fruits was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and expressed as IC50. Antimicrobial activity was evaluated against pathogens (E. coli, B. subtilis, S. aureus) using agar diffusion method. The results showed that very strong antioxidants were detected in domestic and imported lemon juice (33.45 ppm; 31.43 ppm) and peel (15.89 ppm; 44.50 ppm). However, lime juice and peel had stronger antioxidant activity (60.35 ppm and 59.54 ppm). The highest zone of inhibition was observed against S. aureus and the lowest was recorded against E. coli. The diameters of the zones of inhibition of local lemon, imported lemon, and lime juice against S. aureus were 26.40 mm, 27.95 mm, and 27.31 mm; E. coli was 15.64 mm, 16.84 mm, and 16.63 mm; and B. subtilis was 17.88 mm, 21.77 mm, and 21.24 mm, respectively. Tropical citrus juice showed higher activity against Grampositive than Gram-negative bacteria tested. Local lemon, imported lemon, and lime peels did not inhibit E. coli, B. subtilis, and S. aureus. Keywords: Antibacterial, Antioxidant, Lemon, limes, Tropical citrus

Abstract

Moringa functional drink is well known for its benefits for health but has weaknesses in the form of sensory value in aroma and taste, so the addition of red ginger juice and sucralose is necessary. The research aims to determine the quality characteristics of functional drink, which is added with varying concentrations of red ginger juice and sucralose and reviewed based on its physical, chemical, microbiological, and organoleptics. Completely Randomized Design (CRD) was used for research design with two factors and two replications: red ginger juice (30%, 40%, and 50%) and sucralose (100 ppm, 150 ppm, and 200 ppm). The ANOVA showed significantly different results (α = 0.05) for total dissolved solids, antioxidant activity values, and organoleptic tests. The best treatment was obtained by adding a concentration of 40% red ginger juice and 150 ppm sucralose, with a total dissolved solids value of 4.97˚Brix, an IC₅₀ antioxidant activity value of 46 ppm indicating very strong antioxidant activity, the hedonic test score was in score range of 4 for color and 5 for aroma and taste. The metals contamination is below the threshold, the total plate number is <1×10³ colonies/ml, and the yeast mold number is <1×10² colonies/ml. Keywords: Antioxidant, Functional, Moringa, Red Ginger, Sucralose.

Abstract

Pagelaran Village, Ciomas, Bogor, has several food product MSMEs that do not yet have packaging labels. Packaging labeling is an important thing to consider because it can influence consumer decisions in purchasing food products, so socialization related to this is important to do. The PKM activities carried out aim to socialize packaging labeling in several food product MSMEs and increase respondents' knowledge regarding food labels. The socialization method is carried out through lectures and demonstrations. The level of success of the socialization is measured using the pre-test and post-test methods using Google Forms. The results of the success measurement show that there is an increase in the knowledge of socialization participants regarding food packaging labeling and the components contained therein. These results also show that there is an increase in participants' knowledge regarding things that are not allowed to be included in food labels

Abstract

Green cincau (Premna oblogifolia Merr) can form gel, but it is fragile and easily syneresis, so gelatine is needed as another gel-forming material. However, the addition of gelatine with high concentration causes hard texture, therefore iota carrageenan as an alternative gel-forming material is substituted. The purpose of this study was to determine proper ratio of gelatine and iota-carrageenan concentrations for the quality of green grass jelly products. The experiment was arranged in completely randomized design (CRD) with 5 ratios of Gelatine to Iota Carrageenan, namely P1 (10%:0%), P2 (7%:3%), P3 (5%:5%), P4 (3%:7%) and P5 (0%:10%). Data was analyzed using ANOVA followed by HSD test at α = 0.05 for texture test, water content, ash content, antioxidant activity value, and organoleptic test. Results showed that the best treatment for green cincau jelly was treatment P3 with gel strength at hardness parameters of 2200.23 gf, springiness 0.96%, chewiness 1911.30 gf, and gumminess 2111.98 gf due to the interaction between gelatine and iota carrageenan. The water content was 47.28%, ash content was 1.06%, antioxidant content was 374.83 ppm, hedonic values for all parameters were in the range of 4 (taste) and 5 (colour, aroma, texture) and the results of the number of yeast molds <1×102 colonies/ml.
