Abstract

Keadaan pandemi covid-19 saat ini, menuntut masyarakat untuk selalu menerapkan gaya hidup sehat. Salah satu bentuk gaya hidup sehat adalah dengan sering mengkonsumsi buah, sayur dan bunga yang mengandung antioksidan untuk memperkuat sistem imun tubuh. Rosella merupakan salah satu tanaman yang memiliki antioksidan tinggi untuk meningkatkan kekebalan tubuh dan juga sebagai obat herbal. Rosella biasanya hanya dibuat menjadi teh, dapat diubah menjadi sediaan dalam bentuk tablet effervescent dengan keunggulan yang lebih praktis. Penelitian ini bertujuan untuk mengetahui karakteristik tablet effervescent yang menggunakan ekstrak bunga rosella dengan penambahan vitamin C yang berbeda dan untuk mengetahui perubahan karakteristik effervescent yang paling baik menggunakan penambahan vitamin C. Desain penelitian dilakukan dengan 2 faktor perlakuan yaitu konsentrasi vitamin C (100 dan 150 mg) dan konsentrasi bubuk rosella (2½, 3, dan 3½ g). Hasil penelitian menunjukkan bahwa laju larutan tablet effervescent pada semua perlakuan tidak berbeda nyata dengan waktu tercepat yaitu 2,24 menit/g. Hasil analisis pH tidak berbeda nyata dengan nilai 4,50-5,03. Hasil uji warna menunjukkan bahwa warna tablet dan larutan dipengaruhi oleh penambahan konsentrasi vitamin C dan serbuk ekstrak rosella. Hasil analisis uji kadar air menunjukan bahwa penambahan 100 mg vitamin C serta penambahan ekstrak bubuk rosella 3 dan 3½ g mengalami peningkatan. Hasil analisis aktivitas antioksidan produk tablet effervescent konsentrasi bubuk rosella.

Abstract

Probiotic drinks contain a number of live bacteria that are beneficial for maintaining the natural microflora of the human digestive tract in a balanced state. Guava plants are plants that have the potential to be used as functional foods, one of which is probiotic drinks. The purpose of this study was to determine the characteristics of probiotic drinks with treatments, namely different types of guava leaves and different cultures of lactic acid bacteria used. The experimental design used is a completely randomized design (CRD) with 2 treatments, namely differences in the type of guava leaves and LAB used. The pH analysis results showed that white guava with Lactobacillus acidophillus culture had the most acidic pH. The test results of red guava with Lactobacillus casei culture get the lowest value of total soluble solids and the brightest color. The highest viscosity is white guava with Lactobacillus casei culture. Descriptive tests of all attributes were not significantly different except for the sour taste attribute. Hedonic test showed that panelists disliked probiotic drinks with Lactobacillus casei culture. Keywords: Probiotics Drink, Guava Leaf, Leaf Type, Lactobacillus casei, Lactobacillus acidophillus

Abstract

Sourdough is a fermented mixture of water and flour. Sourdough can be used in making bread with good nutritional content. Instant yeast which is usually used for making bread has adverse effect on health if consumed directly compared to using natural yeast. However, currently sourdough is being developed as a bread developer. This research aims to analyze the effect of the concentration of natural yeast on the physical and chemical characteristics, the shelf life and sensory properties of rice bran bread. The method of this research used a Completely Randomized Design (CRD) with control variables of instant yeast and sourdough concentration of 10%; 20%; 30%; and 40% of the total weight of flour. The tests carried out include the physical quality of the bread, organoleptic tests and proximate content tests. Based on the results of the ANOVA test for texture and color, the same results were obtained so that the best results were determined based on the organoleptic testing, which is rice bran bread with 30% sourdough concentration. Based on proximate analysis, it shows that sourdough rice bran bread has a lower total energy content (195.51 kcal/100g), fat content (3.36%), NaCl content (1.49%), carbohydrate content (26.98%) and reducing sugar (5.39%) also has higher protein content (14.34%) than ricebran bread that uses instant yeast. Sourdough rice bran bread has a longer shelf life compared to rice bran bread using instant yeast.  Keywords: bread, physical and chemical qualities, rice bran, shelf-life, sourdough

Abstract

Soursop leaf drink with the addition of ginger is a powder drink product which is developed into a functional food because it contains antioxidants which are good for health. Drinks in the form of powders have a low water content, so they last longer during storage. The quality of the drink can be maintained with proper packaging and storage temperature. The purpose of this study was to determine the effect of temperature and storage time of soursop leaf powder drink with the addition of ginger in metalized packaging to maintain product quality and extend shelf life. This study used a 2-factor Completely Randomized Design (CRD) with temperature treatment (10⁰C and 27⁰C) and storage time (1, 2, and 3 weeks), each treatment was repeated 3 times. Analysis was performed on 4 parameters, namely, water content, water activity, pH, and antioxidant activity. The results showed that there was a significant effect of temperature and storage time on water content, water activity, color, pH solubility, and antioxidant activity.Keywords: powder drink, antioxidant activity, soursop leaves, ginger

Abstract

Pumpkin is an abundant agricultural commodity that has not been utilised to its full potential. People's consumption patterns that are moving towards gluten-free processed foods are an opportunity for the development of processed pumpkin products. Instant noodles are one of the processed products that are in demand by the public. This study aims to determine the physicochemical characteristics of gluten-free pumpkin instant noodles. Gluten-free pumpkin instant noodles were tested proximate, colour and texture. This research used experimental method with 1 type of instant noodle formulation. The results of this study showed that gluten-free pumpkin instant noodles contained protein content of 4.87% protein, 4.09% water content, 19.47% fat content, 4.03% ash content, and 67.32% carbohydrate content. Texture analysis included hardness, stickiness and tackiness with values of 13.42 N, 0.03 mJ, and 4.62 N, respectively. Colour values showed a brightness of 53.29 with the colour of the noodles tending to brown.

Abstract

Gula cair banyak dipilih oleh industri makanan dan minuman karena kelebihannya yang tidak mudah mengkristal, lebih praktis, dan mudah dilarutkan, serta dapat mempercantik tampilan produk seperti pada industri roti. Pisang, khususnya pisang tanduk, dengan kandungan karbohidrat dan pati yang tinggi memiliki potensi yang besar untuk dikembangkan menjadi gula cair melalui proses hidrolisis enzimatik dengan menggunakan enzim α-amilase dan glukoamilase. Tujuan penelitian ini yaitu untuk mengkaji pengaruh kondisi proses konsentrasi substrat dan lama proses sakarifikasi terhadap pembuatan gula cair dari pisang tanduk dengan menggunakan metode enzimatis dengan penambahan enzim glukoamilase pada proses sakarifikasi. Penelitian ini dilakukan dengan metode Rancangan Acak Lengkap (RAL) model faktorial dengan 2 faktor. Faktor pertama adalah waktu sakarifikasi (6 jam dan 8 jam) dan faktor kedua adalah konsentrasi substrat (15%, 20% dan 25%). Penggunaan waktu sakarifikasi dan jumlah konsentrasi substrat berpengaruh secara signifikan terhadap viskositas, kadar abu, dan intensitas warna. Perlakuan terbaik adalah waktu sakarifikasi selama 8 jam dan konsentrasi substrat pati 25% (b/v) yang menghasilkan nilai viskositas sebesar 41,50 mPa.s, nilai kadar abu 0,35%, dan nilai L*, a*, dan b* berturut-turut sebesar 47,27±0,12cd, 0,30±0,03a, dan 2,25±0,03b.
