Abstract

Cangkang udang berpotensi untuk dijadikan sebagai bahan baku dalam proses pembuatan nanokalsium. Tujuan dari penelitian ini yaitu memanfaatkan cangkang udang vannamei menjadi nanokalsium, menentukan karakteristik nanokalsium secara fisik dan kimia serta mengetahui bioavailabilitas nanokalsium yang dihasilkan. Pembuatan nanokalsium dilakukan dengan metode presipitasi. Nanokalsium memiliki rendemen optimum oleh perendaman cangkang udang selama 48 jam (13,92%). Kadar kalsium optimum dihasilkan oleh perendaman cangkang udang selama  48 jam (85,49%). Hasil analisis AAS menunjukkan nanokalsium masih mengandung komponen mineral lain yaitu magnesium, kalium, natrium, fosfor, besi, seng, dan mangan. Nanokalsium yang dihasilkan memiliki nilai pH sebesar 9,40. Ukuran partikel nanokalsium berkisar antara 37-127 nm. Nanokalsium memiliki nilai derajat putih berkisar 81,73-93,39%, dengan rata-rata 87,56%.  Bioavailabilitas nanokalsium cukup tinggi pada menit ke-7 yaitu sebesar 63,3%.   Kata kunci : AAS, bioavailabilitas, cangkang udang Vannamei, nanokalsium, dan SEM

Abstract

Vitamin adalah komponen tambahan makanan yang berperan penting dalam gizi manusia. Ketersediaan vitamin dalam makanan berkaitan dengan kelarutannya dalam air atau lemak. Vitamin biasanya dikelompokkan ke dalam dua golongan utama, yaitu vitamin larut air dan vitamin larut lemak. Beberapa vitamin tidak stabil terhadap pemerosesan dan penyimpanan sehingga kandungannya dalam makanan dapat menurun. Penelitian ini bertujuan untuk mengetahui pengaruh perebusan terhadap komposisi kimia dan vitamin A, B12, dan B6 daging udang ronggeng.Udang ronggeng segar memiliki nilai rendemen, yaitu 41,13 % daging; 54,25 % cangkang; dan 4,62 % jeroan. Komposisi kimia, yaitu kadar air (bb) 76,55 %; abu (bk) 5,41 %; protein (bk) 87,09 %, dan lemak (bk) 6,57 %. Kadar vitamin, yaitu vitamin A 81,77 μg/100 g; vitamin B6 0,15 μg/100 g; dan vitamin B12 1,29 μg/100 g. Udang ronggeng rebus memiliki nilai rendemen, yaitu 20,08 % daging; 45,32 % cangkang; dan 1,69 % jeroan dengan nilai rendemen yang hilang sebesar 32,9 %. Komposisi kimia, yaitu kadar air (bb) 73,1 %; abu (bk) 5,37 %; protein (bk) 86,36 %; dan lemak (bk) 3,20 %.

Abstract

Carp as food is processed into various products, including pepes, bekasam, fried carp, as well as new products such as fried carp made from juvenile fish. The purpose of this study was to determine the proximate, the type and amount of fatty acids juvenile carp at harvest age 3, 5, and 7 weeks. Protein and ash content increased from harvest age 3 weeks to 5 and 7 weeks while the fat content decreased. Fatty acid profile consisting of 5 types of SAFA, 1 type of MUFA, and 3 type of PUFA 3. Oleic fatty acid is a predominant fatty acid. The content of SAFA decreased with increasing age of harvest, i.e from 36.36% (3 weeks) to 30.78% (5 weeks) and 10.04% (7 weeks). Instead PUFA content increased from 17.93% (3 weeks) to 20.09% (5 weeks) and 44.25% (7 weeks).

Abstract

Fish represent one of protein source. Patin ( Pangasius Sp) is representing one of prospect commodity because it has been cultured better. Fish snack (product extrusion) is food which it enhanced with fish to increase its nutrition. Water rate become critical point and determine characteristic of snack during production and depository. Assessment of age keep fish snack was done by acceleration method pursuant to rate of critical water with sorption curve approach. This research aim to evaluate age keep fish snack with critical water rate approach that is isothermal sorption approach curve and compare it with age keep determined by manual calculation. measure This research is divided become 2 phase; especial research and antecedent research. Antecedent research was conducted in a few phase which are making of fish snack, measuring of rout snack parameter through consumer survey, and determinating of characteristic early product using proximate analysis and cracking test. Especial research are conventional method for rate proximate analyze, TPC, TBA, cracking, and organoleptic every week during depository temperature 30 0C. Calculating of critical water rate, balance water rate, model and isothermal sorption curve, MRD value, slope, package permeability, weight and wide package for calculation of age keep Labuza at acceleration method using critical water rate approach. Based on this research; equation model chosen is model Caurie. Critical water rate both types of the product by hedonic; fish snack without flavor is 0,125 g H2O/G solid and fish snack with flavor is 0,078 g H2O/G solid. Based on critical water rate, both types of the product; fish snack without flavor is 0,124 g H2O/G solid and fish snack with flavor is 0,077 g H2O/G solid. Cracking value that obtained on hedonic test 1164,74 gf for snack TF and 874,54 gf for snack DF. Based on rating test, value of cracking is 1164,04 gf for snack TF and 861,38 gf for snack DF. Value of aw for snack TF is 0,15 and 0,16 for snack DF. Age keep fish snack through isothermal sorption curve approach is 2,9-4,3 month for snack TF and 0,4-0,9 month for snack DF by rating test and also hedonic test on RH depository condition about 85 %. At conventional depository method, fish snack have shown of quality retreating of depository for four weeks, but still be consumed. Isothermal sorption curve approach is representing more precise method in determination of age keep fish snack though has not perfect sigmoid curve, according to Labuza statement. Influenced factors of age keep in general are early water rate, critical water rate, balancing water rate, RH, and packaging. Based on this research can be proved that that isothermal sorption curve approach has advantages; easy to be done, effective, efficient, and cheaper than conventional method in determination of age keep fish snack (product extrusion)

Abstract

Yellow velvetleaf (Limnocharis flava) is aquatic plant and known as vegetable and source of bioactive compound but it has aerenchyma system which affects to its proximate. The research purpose was to determine microscopic characteristics of yellow velvetleaf tissues such as leaf, stem, and root tissue. The proximate and bioactive compound from fresh and steam materials were also evaluated. The methods of the research consisted of plant dimension measurement, making of tissue slide by paraffin method in Johansen-TBA series, phytochemical analysis, proximate and carotenoid total analysis. The results showed that leaf tissue was composed by epidermis unilayer containing stoma, a palisades parenchyma layer, spongy parenchyma layer with some aerenchyma system, and vascular bundle. Stem tissue consisted of epidermis unilayer, cortex containing chlorophyll, starch, and some aerenchyma system, and vascular bundle was amphicribral type. Root tissue was composed by rhizodermis, cortex with aerenchyma system, endodermis multilayer, and vascular bundle. Fresh yellow velvetleaf contained 91,76% of moisture, 12,40% of ash, 7,95% of fat, 22,96% of protein, 11,93% of crude fibre, and 219,01 g/g of carotenoid total in its leaf. Its stem contained 95,33% of moisture, 16,38% of ash, 5,62% of fat, 13,23% of protein, 16,12% of crude fibre, and 92,99 g/g of carotenoid total. Steaming decreased crude fibre content, but increased ash, fat, and protein content. Steaming also increased leaf carotenoid total, but decreased stem carotenoid total. Leaf extract contained flavonoid, phenol, reducing sugar, and amino acid. Stem extract was composed by flavonoid, reducing sugar, amino acid. Flavonoid and reducing sugar were major bioactive compounds in this plant.
