Abstract

Fosfor merupakan nutrisi penting bagi manusia dan hewan. Selain itu, fosfor juga penting untuk pertumbuhan, pemeliharaan, perbaikan semua jaringan tubuh, dan dibutuhkan bersama dengan kalsium dan magnesium untuk pertumbuhan dan pembentukan tulang pada bayi dan anak-anak. Penelitian ini bertujuan untuk mengetahui kandungan fosfor dalam kubis putih dan ungu. Fosfor diukur dengan metode spektrofotometri Visibel, meliputi validasi analisis yang terdiri atas penetapan linieritas, batas deteksi dan batas kuantisasi, akurasi dan presisi serta analisis kadar fosfor pada sampel. Hasil penelitian menunjukan nilai linieritas 0,9991, batas deteksi dan kuantisasi dihitung secara statistik, dengan nilai 0,38 μg /ml dan 1,25 μg / ml. Presisi intra- day dan inter-day Nilaiinyatakan sebagai koe sien variansi (CV) ditentukan dalam tiga hari yang berbeda. Nilai presisi inter-day masing masing 0,67; 0.60; dan 0,80%, untuk presisi intra-day 0,82% . Perolehan kembali tingkat konsentrasi 2,0; 3,0; 4.0; dan 5,0 ug / ml kisaran 86,33% -105,01%. Kadar fosfor dalam kubis putih 20,725 mg/g, dalam kubis ungu 14,525 mg/g Dari hasil tersebut kadar fosfor dalam kubis putih ternyata lebih besar dibandingkan dengan kubis ungu tetapi kadar Fosfor tidak dipengaruhi oleh warna kubis. Kubis merupakan makanan kaya serat dan dapat dijadikan sebagai bahan makanan alternatif sebagai sumber fosfor. Kata Kunci : Fosfor (p), spektrofotometri, kubis.

Abstract

Food allergies are one of the most common allergies in Indonesian society. Generally, when children aged 5-6 years food allergies will disappear, except peanut allergies and allergies to seafood, such as fish, shellfish and crustaceans. This study aims to determine the pattern of separation of allergen proteins in shrimp using anion exchange column chromatography method and identify allergen proteins in shrimp using the sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) method. Protein extraction from shrimp using Phosphate buffer saline (PBS) pH 7.2 and centrifuged at 10,000 rpm for 10 min at 4°C. Protein separation was carried out by anion-exchange column chromatography method, and the fraction obtained was measured at 280nm wavelength. The highest yield at absorbance was identified by using SDS-PAGE. Polyacrylamide gel electrophoresis was used to determine the protein profile and molecular weight of shrimp extract. Coloring of protein bands using silver staining. Data were analyzed descriptively based on the migration value of the sample protein bands compared to the marker protein band (Rf). The results of protein allergen profile analysis on shrimp using SDS-PAGE showed that the shrimp contained a protein band with a molecular weight of 37.77 kDa for cooked shrimp and 37.03 kDa for fresh shrimp.
