Abstract

Tiger prawn head naturally has a taste as it contains amino acids which give the food a savory taste. Accordingly, it is possible and necessary to process tiger prawn head into a broth that can be used as a natural food additive in processed products. Broth is made by boiling prawn heads with water to produce a liquid broth. In fact, liquid broth tends to spoil quickly, so it is necessary to change its form to powder (dried broth). This study aims to determine level of consumer preference for powdered broth from tiger prawn head with various types of fillers. Treatments given were a combination of fillers, including control (wheat flour), T1 (combination of wheat flour and tapioca), T2 (combination of wheat flour and cornstarch), T3 (combination of wheat flour and rice flour), and T4 (combination of wheat flour and glutinous rice). Hedonic test used 30 untrained panelists, while data were processed using Randomized Complete Block Design followed by Duncan's test with 95% confidence level. Results of this study showed that addition of fillers could affect panelists’ preference. Moreover, resulting powdered shrimp broth had a fine-grained texture (TI to T4), coarse or easily lumpy (control group), light creamy color (T1 to T4) to brownish yellow (control and comparison groups). Based on consumer acceptance, combination of wheat flour and tapioca (T1) was the best treatment with value of appearance of 8.30 (strongly like), color of 8.23 (strongly like), aroma of 8.33 (strongly like), and taste of 8.30 (strongly like). Kepala udang windu secara alami memiliki cita rasa karena mengandung asam amino yang memberikan rasa gurih pada makanan, sehingga perlu dilakukan pengolahan menjadi kaldu sebagai bahan tambahan pangan alami yang dapat ditambahkan pada produk olahan. Kaldu diperoleh dengan cara direbus menggunakan air sehingga dihasilkan kaldu cair. Kaldu cair akan cepat mengalami kerusakan, sehingga perlu merubah bentuknya menjadi bubuk (kering). Penelitian ini bertujuan untuk mengetahui tingkat kesukaan konsumen terhadap kaldu bubuk dari kepala udang windu dengan berbagai jenis bahan pengisi. Perlakuan yang digunakan adalah kombinasi bahan pengisi, yaitu kontrol (tepung terigu), T1 (kombinasi tepung terigu dan tapioka), T2 (kombinasi tepung terigu dan maizena), T3 (kombinasi tepung terigu dan tepung beras), serta T4 (kombinasi tepung terigu dan beras ketan). Pengujian hedonik menggunakan 30 orang panelis tak terlatih dan data diolah menggunakan Rancangan Acak Kelompok Lengkap dan dilanjutkan dengan uji Duncan pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa penambahan bahan pengisi dapat mempengaruhi tingkat kesukaan panelis. Kaldu udang bubuk yang dihasilkan mempunyai tekstur berbulir halus pada TI sampai T4, berbulir kasar atau mudah sekali menggumpal pada kontrol, berwarna krem terang pada T1 sampai T4 hingga kuning kecoklatan pada kontrol dan pembanding. Kombinasi tepung terigu dan tapioka (T1) merupakan perlakuan terbaik berdasarkan penerimaan konsumen dengan nilai kenampakan 8,30 (sangat suka), warna 8,23 (sangat suka), aroma 8,33 (sangat suka), dan rasa 8,30 (sangat suka).

Abstract

Jelly candy has a characteristic sweet taste and a chewy texture. Another factor that determines the quality of jelly candy besides the taste and texture is the color. One of the ingredients that has the potential as a natural dye is red dragon fruit which has a sweet taste and is good for increasing endurance. This study aims to determine the addition of dragon fruit as a natural dye to the physicochemical and hedonic characteristics of jelly candy from seaweed Kappaphycus alvarezii. The concentration of dragon fruit juice used is P0: dragon fruit juice 0%, P1: dragon fruit juice 7.5%, P2: dragon fruit juice 10%, P3: dragon fruit juice 12,5%, P4: dragon fruit juice 15%, and P5: dragon fruit juice 17.5%. This study used a completely randomized design for proximate and color tests, and Kruskal-Wallis for hedonic tests. The results showed that the addition of dragon fruit juice had a significant effect (p<0.05) on moisture content, ash content, protein content, fat content, color and hedonic value (color, taste, texture, aroma). The moisture content of the jelly candy ranges from 14.81-22.80%, the ash content ranges from 1.60-3.66% and has met the standard of SNI 3547.2-2008. The brightness value of jelly candy ranges from 12.51-14.06%. The hedonic sensory test (scale 1-5) showed that the jelly candy was well received by the panelists, based on the parameters of color (4.30), taste (3.97), texture (3.97), and aroma (3.77).

Abstract

Fish balls containing high protein but low in fiber need to be diversified to increase the nutritional value while reducing the cost of raw materials. Kappaphycus alvarezii seaweed is rich in fiber and the price is relatively cheaper, so it has the potential to be used as raw material for making fish balls. This study aims to determine the physicochemical characteristics and consumer acceptance of catfish meatballs (Clarias sp.) with the addition of K. alvarezii seaweed. The study used a completely randomized design with four treatments, namely the percentage of seaweed substitution for fish meat (w/w) namely 40%, 50%, 60% and 0% (control) with three replications. Parameters observed were proximate composition, whiteness degree, and hedonic test. The addition of seaweed increased the water content, ash, carbohydrates and whiteness value of fish balls but decreased the protein and fat content. Consumers still prefer the formulation of fish balls without the addition of K. alvarezii seaweed, but that is close to consumer preferences with the addition of 40% seaweed.

Abstract

Kappaphycus alvarezii is widely used because it contains agar, carrageenan, porpyran, furcelaran and phycobilin pigments (consisting of phycoerethrin and phycocyanin). Optimization of the utilization of K. alvarezii still needs to be improved in an effort to diversify processed products from seaweed. One of the processed seaweed products that can be developed is crackers. This research was conducted to determine the physicochemical characteristics and consumer acceptance of K. alvarezii seaweed crackers. The treatment used in this study included 3 main ingredients, namely K.alvarezii seaweed, wheat flour, and tapioca flour. Data were processed using a completely randomized design (CRD) and continued with Tukey test at 95% confidence level. The results showed that K.alvarezii seaweed crackers had a moisture content between 11.41-14.52%, protein content 6.03-9.58%, fat content 3.51-5.68, and ash content 2.58 -4.11%. The protein content of seaweed crackers meets SNI 0272-2000 standards, but the ash content and moisture content of the crackers do not meet SNI standards. The degree of whiteness of the seaweed crackers ranged from 50.69-61.30%, the swelling power of the crackers ranged from 41.10-92.27%. Based on consumer acceptance, treatment P2 with a concentration of 40% seaweed, 12% wheat flour, and 28% tapioca flour was the most preferred treatment by consumers with an overall preference range of 5.40-6.57 (rather like to like very much). Keywords: Kappaphycus alvarezii, Physicochemical Characteristics, Crackers, Consumer Acceptance.   Kappaphycus alvarezii banyak dimanfaatkan karena mengandung agar, karaginan, porpiran, furcelaran maupun pigmen fikobilin (terdiri dari fikoeretrin dan fikosianin). Optimalisasi pemanfaatan K. alvarezii masih perlu ditingkatkan dalam upaya diversifikasi produk olahan dari rumput laut. Salah satu olahan produk rumput laut yang bisa dikembangkan adalah kerupuk. Penelitian ini dilakukan untuk mengetahui karakteristik fisikokimia dan penerimaan konsumen kerupuk rumput laut K. alvarezii. Perlakuan yang digunakan pada penelitian ini meliputi 3 bahan utama yaitu rumput laut K.alvarezii, tepung terigu, dan tepung tapioka. Data diolah menggunakan Rancangan Acak Lengkap (RAL) dan dilanjutkan dengan uji Tukey pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa kerupuk rumput laut K.alvarezii memiliki kadar air antara 11,41-14,52%, kadar protein 6,03-9,58%, kadar lemak 3,51-5,68, dan kadar abu 2,58-4,11%. Kadar protein kerupuk rumput laut telah memenuhi standar SNI 0272-2000, namun kadar abu dan kadar air kerupuk belum memenuhi standar SNI. Derajat putih kerupuk rumput laut berkisar antara 50,69-61,30%, daya kembang kerupuk berkisar antara 41,10-92,27%. Berdasarkan penerimaan konsumen, perlakuan P2 dengan konsentrasi rumput laut 40%, tepung terigu 12%, dan tepung tapioka 28% merupakan perlakuan yang paling disukai konsumen dengan rentang kesukaan keseluruhan sebesar 5,40-6,57 (agak suka sampai sangat suka).

Abstract

Catching and fishery processing produces a variety of by-products that can affect the economy and cause environmental problems. Fish by-products such as heads, skin, bones, fins, innards, blood, and scales can reach more than 55-70%. Fish by-products have the potential to be processed into value-added products. Fish by-products can be a source of additional compounds because they are rich in protein, peptides and amino acids. Fish protein hydrolyzate is obtained from hydrolyzed fish by-products and then produces peptides and amino acids with a mixture of small protein molecules. The hydrolysis process releases the active site on the peptide previously encrypted in the native structure of the protein and produces a biomolecule called Bioactive Peptide (BP). This review aims to explain fish by-products as a source of peptides, the methods used to obtain BP from fish by-products, and the mechanisms of their biological activity as antihypertensive and antioxidant peptides. Keywords: Amino acids, enzymatic hydrolysis, fish protein, protein hydrolysate Penangkapan dan pengolahan hasil perikanan menghasilkan beragam hasil samping yang dapat mempengaruhi perekonomian serta menimbulkan masalah terhadap lingkungan. Hasil samping perikanan seperti kepala, kulit, tulang, sirip, jeroan, darah, dan sisik dapat mencapai lebih dari 55-70%. Hasil samping perikanan memiliki potensi untuk diolah menjadi produk yang bermanfaat. Produk hasil samping perikanan dapat menjadi sumber senyawa tambahan karena kaya akan kandungan protein, peptida, dan asam amino. Hidrolisat protein ikan diperoleh dari hasil samping perikanan yang dihidrolisis dan selanjutnya menghasilkan peptida dan asam amino dengan campuran dari potongan-potongan protein berukuran kecil. Proses hidrolisis membuka sisi aktif pada peptida yang sebelumnya terenskripsi didalam struktur primer protein dan menghasilkan biomolekul yang disebut Peptida Bioaktif (PB). Review ini bertujuan untuk menjelaskan mengenai hasil samping perikanan sebagai sumber peptida, metode yang digunakan untuk memperoleh PB dari hasil samping perikanan serta mekanisme aktivitas biologisnya sebagai peptida antihipertensi dan antioksidan.
