Abstract

Daun kelor merupakan tanaman yang banyak ditemui di Indonesia. Tanaman ini mengandung banyak gizi, tetapi pemanfaatannya masih rendah. Agar gizi tersebut dapat dimanfaatkan maka perlu dilakukan inovasi makanan yang dapat diterima oleh masyarakat. Salah satu inovasi yang dipilih adalah samosa. Pemilihan hidangan tersebut dikarenakan rasa dari rempah dapat menutupi rasa dan aroma khas daun kelor. Penelitian dilaksanakan untuk mengetahui daya terima secara sensoris dan nilai gizi (energi dan ß-karoten) samosa. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 6 kali pengulangan pada 4 formula. Formula kontrol (F0) dan  3 formula modifikasi (F1,F2, dan F3), samosa diujikan kepada 50 panelis tidak terlatih dengan penambahan kelor sebesar 17,5%; 20% dan 22,5%. Analisis data menggunakan analisis deskriptif dan analisis statistik menggunakan uji Kruskal Wallis dan Mann Whitney Test (a = 0,05). Analisis daya terima menunjukkan bahwa formula samosa daun kelor dapat diterima secara umum (rasa, aroma, tekstur, dan warna) dengan kategori suka (3) hanya pada formula F1 (penambahan daun kelor paling sedikit). Warna dan tekstur tidak berbeda nyata, sedangkan aroma berbeda nyata. Formula terbaik yang direkomendasikan yaitu F1 (daun kelor 17,5%) dengan kandungan zat gizi sebesar 164 kkal dan 604 mcg ß-karoten per 100 g. Received Power and Samosa Nutrition Substance with Addition Of Moringa olieferaMoringa leaves are plant parts that are commonly found in Indonesia. This plant contains high nutrients, but its use is still limited. To utilize these nutrients, it is necessary to innovate a food that accepted by the communities. One of the food was samosa, the choice of the dish was due to the taste of the spices that able to cover the flavor and aroma typical of moringa leaves. This research was carried out to determine the sensory reception and nutritional value (energy and ß-carotene) of samosa. The study was conducted using a completely randomized design (CRD) with six replicates on four formulas. Control formula (F0) and three modified samosas recipes (F1, F2, and F3), were tested to 50 untrained panelist with the addition of moringa were 17,5%; 20% and 22.5%. Data analysis used descriptive analysis and statistical analysis using the Kruskal Wallis test and Mann Whitney Test (a = 0.05). Analysis of acceptability indicate that samosa with F1 formula (the least addition of moringa leaves) was generally accepted (taste, aroma, texture, and color) with the category of the likes (3), Color and texture were not significantly different mean while aroma was significantly different. The best formula recommended is F1 (17,5% moringa leaves) with nutrient content of 164 kcal and 604 mcg ß-carotene per 100 g of samosa.

Abstract

Pencoklatan pada buah salak disebabkan oleh aktivitas enzim polifenol oksidase (PPO) yang bereaksi dengan oksigen menghasilkan o-kuinon yang membuat warna menjadi coklat, oleh karena itu adanya penghambatan kerja enzim PPO, dapat mencegah terjadinya warna coklat pada buah. Tujuan penelitian ini adalah untuk mengetahui pengaruh aplikasi rebusan daun zaitun dalam rangka untuk mencegah terjadinya warna coklat yang dianalisis berdasarkan pada parameter penyertanya, yaitu warna, pH, gula terlarut, dan konduktivitas pada buah salak. Daun zaitun kering dilarutkan dalam air yang kemudian dimasukkan ke dalam wadah plastik berisi potongan salak. Sebagai kontrol, potongan salak disimpan dengan dan tanpa aquades. Pengamatan terhadap salak dilakukan sebanyak 7 kali selama 9 hari pada suhu kamar. Berdasarkan parameter warna, perlakuan zaitun mampu menahan warna lebih baik sebesar 28,17% pada nilai L*, 53,68% pada nilai a*, dan 27,19% pada nilai b*. pH salak dengan perlakuan zaitun dapat dijaga sehingga kenaikannya hanya sebesar 3,8% dan nilai konduktivitas hanya meningkat sebesar 18,5%. Pada parameter gula terlarut, perlakuan dengan zaitun dapat mempertahankan perubahannya sampai sebesar 4,29%. Kesimpulannya, perlakuan penambahan daun zaitun lebih baik dalam mempertahankan warna, derajat keasaman, konduktivitas dan gula terlarut pada buah salak daripada perlakuan dengan dan tanpa penambahan aquades. Application of Olive Leaves Extract (Olea europaea L.) in Vacuum Packaging to Prevent Browning on Salacca FruitBrowning occurs due to the activity of the polyphenol oxidase (PPO) enzyme that reacts with oxygen to produce O-quinone which causes the forming of brown color on fruit.

Abstract

Saat ini penggunaan keju mozarella di Indonesia berkembang pesat. Sejumlah titik kritis menentukan mutu mozarella, antara lain total padatan susu yang tinggi, rennet yang aktif, proses curdling yang baik, mild temperatur saat peregangan/pemuluran (58-65°C). Jika tidak terpenuhi maka mutu mozarella yang dihasilkan kurang baik, antara lain sifat regang yang rendah yang berakibat terhadap kurangnya daya leleh keju. Diperlukan aplikasi bahan pengental berupa hidrokoloid untuk memperbaiki sensori, yaitu memperbaiki sifat kemuluran atau daya leleh mozarella yang lebih baik. Penelitian ini bertujuan untuk mengetahui sifat fisikokimia keju mozarella dengan penambahan hidrokoloid sebagai bahan pengental. Penelitian didesain menggunakan rancangan acak lengkap dengan 4 perlakuan penambahan hidrokoloid dan satu kontrol tanpa bahan pengental, yaitu: P0 (kontrol); P1 (gellan gum 0,010%); P2 (xhantan gum 0,010%+ gellan gum 0,010%); P3 (pati jagung/maizena 0,125%); dan P4 (susu skim bubuk 0,125%), masing-masing diulang 3 kali. Hasil penelitian menunjukkan bahwa keju mozarella susu sapi dengan perlakuan penambahan pengental berupa hidrokoloid pati jagung (maizena) merupakan keju yang memiliki karakteristik terbaik dengan kadar lemak yang cukup baik (12,08%), tingkat hardness terendah (150,13 g/mm2), lelehan keju yang lembut, serta kecerahan warna yang baik (L= 88,99). The Effect Of Thickener On Characteristics Of Cow Milk Mozarella Cheese.Nowaday, the use of mozzarella cheese is growing rapidly in Indonesia. A number of critical points determine the quality of mozzarella, including high milk total solids, active rennet, good curdling process, mild temperature during stretching (58-65°C). The quality of the mozzarella produced is not good, among others lack of stretching ability causes low melting ability if the critical points are not fulfilled. The application of a hydrocolloid as thickener is needed to improve the sensory that was better stretching ability of mozzarella. The aim of study was to determine the mozzarella physicochemical characteristics use the addition of hydrocolloid as thickener. The study was designed using a completely randomized design with 4 treatments for addition of hydrocolloid and control without thickener, namely: P0 (control); P1 (gellan gum 0.010%); P2 (0.010% xhantan gum + 0.010% gellan gum); P3 (corn starch 0.125%); and P4 (powdered skim milk 0.125%), each repeated 3 times. The results showed that cow milk mozzarella cheese with the treatment of corn starch (maize starch) as thickener was the best cheese with good fat content (12.08%), the lowest hardness level (150.13 g/mm2), smoothy melted cheese and good colour brightness (L value of 88.99).

Based on the research result of change in the physicochemical properties, the microwave energy which was used in the puffing process to test the popping hanjeli has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality on the tests of water, fat, carbohydrate content and organoleptic testing on color and texture parameters with medium energy levels. Time usage of popping hanjeli using the microwave has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality on the tests of water, fat, carbohydrate content and organoleptic testing on color and texture parameters with medium energy level. There is a different interaction between the energy level and time process, it has the real impact with a significant value < α (0.05) towards the popping hanjeli’s quality which at the medium energy level with a time process of 2,5 minutes.
