Abstract

Kulit buah naga merah (Hylocereus polyrhizus) ini memiliki persentase 30-35 %  dari berat buahnya dan seringkali hanya dibuang. Kulit buah naga merah merah mengandung zat warna alami antosianin yang cukup tinggi, vitamin C,  vitamin E, vitamin A, alkaloid, terpenoid, fenolik, karoten, serat dan pektin. Berdasarkan kandungan dari kulit buah naga merah ini dimanfaatkan sebagai pangan fungsional yakni cincau tiruan. Penelitian bertujuan mengetahui karakteristik fisik dan kimia cincau tiruan kulit buah naga merah. Beberapa senyawa yang ditambahkan dalam pembuatan cincau tiruan mempengaruhi karakteristik cincau tiruan sehingga perlu dilakukan analisa fisik dan kimia pada cincau tiruan kulit buah naga merah. Pembuatan cincau tiruan dibuat dari sari kulit buah naga merah dengan penambahan karagenan, CMC – Na, gula dengan perbandingan 1,5:1:0,5. Cincau tiruan dianalisa karakteristik fisik ( pH, total padatan terlarut, warna dan sineresis) dan karakteristik kimia (lemak, protein, air, abu, karbohidrat dan serat kasar). Karakteritik fisik pada cincau tiruan dari kulit buah naga merah didapatkan nilai pH 7,54 ± 0,02, total padatan terlarut 9,32%, warna (L 35,23%±0,64, a+ 8±1,25, b+ 2,33±0,32 dan sineresis 24 jam 6%±0,00, 48 jam 6,30%±0,00, 72 jam 10,28±0,00. Karakteristik kimia pada cincau tiruan dari kulit buah naga merah didapatkan nilai kadar lemak 0,26%±0,00 , protein 4,35%±0,00, air 94,44%±0,00, abu 0,48%±0,00,  karbohidrat 0,48% ±0,00  dan  serat kasar 1,63% ±0,00.

Abstract

Dioksin merupakan senyawa kimia hasil samping dari berbagai proses kimia yang terjadi dibumi terutama dari hasil pembakaran dan mempunyai  toksisitas tinggi.  Salah satu efek toksisitas dari dioksin adalah  terhadap organ reproduksi (reprotoksik). Kasein yoghurt susu kambing mengandung peptida bioaktif yang memiliki potensi sebagai antioksidan. Pada penelitian ini  potensi antioksidan yoghurt susu kambing diuji terhadap tikus putih (Rattus norvegicus) sebagai hewan model reprotoksik yang dipapar 2,3,7,8-Tetrachlorinedibenzo-P-Dioksin (TCDD). Efek pencegahan kasein diamati  berdasarkan kadar superoksida dismutase (SOD) dan malondyaldehide (MDA) serum, kadar MDA dan histopatologi testis.  Metoda yang digunakan adalah percobaan laboratorium menggunakan Rancangan Acak Lengkap. Tikus putih dibagi menjadi 6 kelompok yaitu KN (kelompok normal), KK (kelompok kontrol yang diberi kasein yogurt susu kambing 600 mg/kg BB), KP (kelompok positif yang dipapar TCDD 100 ng/kg BB), KP1 ( KP + preventif kasein yoghurt susu kambing 300 mg/kg BB), KP2 (KP+  preventif kasein yoghurt susu kambing 600 mg/kg BB),  KP3 (KP + preventif kasein yoghurt susu kambing 900 mg/kg BB. Data SOD dan MDA  diuji menggunakan one way Analysis of Variance (ANOVA) dilanjutkan dengan uji Beda Nyata Jujur (BNJ).  Histopatologi testis diuji dengan metode pewarnaan Hematoksilin-Eosin (HE) untuk mengamati secara deskriptif spermatozoa dalam tubulus seminiferus. Hasil penelitian menunjukkan bahwa kasein yoghurt susu kambing secara signifikan berpengaruh (p<0,05) terhadap kadar SOD dan MDA serum, MDA testis dan kepadatan sel spermatozoa akibat paparan TCDD.  Pemberian kasein dosis 900 mg/kg BB paling efektif mencegah penurunan SOD serum, kenaikan kadar MDA serum dan testis, serta penurunan spermatozoa. Dapat disimpulkan bahwa kasein yogurt susu  kambing dapat dapat dimanfaatkan sebagai nutrasetika untuk mencegah reprotoksik akibat paparan TCDD.

Abstract

Stevia is one of natural sweetener a substitute for sugar low calorie. Stevia start widely used as many consumers want sweetening healthy. Stevia leaf powder was used to develop an kefir as sweetener replacer to sugar. The objective of this research was to determine the best percentage of using stevia leaf flour as substitution ingredient on kefir based on total sugar, acidity, total solids and sineresis kefir. The materials research were fresh milk, kefir grain, and stevia leaf flour. The research method was using experimental design with four treatments and four replications. The treatments were P1 0.5 % stevia leaf flour, P2 0.75% stevia leaf flour P3  1% stevia leaf flour and P4 1.25% stevia leaf flour. The data were analyzed by ANOVA and if there were significant effect then would be continued by Duncan’s Multiple Range Test (DMRT). The result showed that substituting sugar using stevia leaf flour gave highly significant different effect (P<0.01) on total sugar, acidity, total solids and sineresis kefir. It can be concluded that the kefir with the used 1.25% stevia leaf flour gave the best result with the total sugar was 6.82 , acidity was 0.55%, total solids was 11.75%, and sineresis was 23.75%.

Abstract

Gelatin is a type of protein that is extracted from collagen of skin, bone, or ligament (animal connective tissue) tissue. Cow bone, cowhide and pig skin are the materials commonly used to obtain gelatin. The purpose of this research was to determine the difference of NaOH concentration as soaking agent on gelatin making from skin of chicken leg (Gallus gallus domesticus) for 72 hours of soaking. Fresh skin of chicken leg weighing 250 g were immersed in NaOH solution with concentrations of 1%, 1.5%, and 3% for 72 hours, then extracted using n-hexane solution: alcohols in a ratio of 1: 3 and dried to obtain gelatin. The resulting gelatin is then analyzed for physicochemical characteristics such as sensory, yield, pH test, and water content test. The results of this study, mentioned that the concentration of 1% NaOH solution produces gelatin under average of yield of 6 g, neutral pH and water content of 11%. The concentration of 1.5% NaOH solution produces gelatin under average of yield 8 g, pH 7 and water content of 13%. The concentration of 3%NaOH solution produces gelatin under average of yield 4.144 g, pH 7 and water content of 7.11%. Based on the result, it can be concluded that a good solution of NaOH to get high yield under a concentration of 1.5% solution. The gelatin obtained under 1.5% solution in accordance with the standard gelatin. The characteristics of standard gelatin are colorless to yellow, odorless, tasteless, pH 7 (neutral), and moisture content below 16%.
