Abstract

Abstract Activated charcoal and imarsil (local adsorbent) had shown significant Aflatoxin (AF) decontamination potentials in vegetable oil at a low AF contamination level of ≤ 9 ng/L. AF contamination in vegetable oils can be more than a hundred-fold of this. Therefore, it is needed to investigate the potential of other adsorbents at higher AF contamination levels. Magnetic Chitosan Nanoparticle (MCNP) was synthesized, and its aflatoxins extraction efficiency from two edible vegetable oils was investigated. MCNP exhibited extraction efficiencies of 82.80 – 100% and 94.87 – 100% in palm kernel oil and palm oil at the contamination levels of 579.6 and 964.6 ng/L respectively. Total aflatoxins cleanup of the palm oil and palm kernel oil was possible at 30 °C within 30 and 60 minutes, respectively, at the optimized condition of 4.4 mg/L MCNP. MCNP concentration, temperature of extraction, and contact time were significant (p < 0.05) in palm kernel oil, while these conditions were not significant (p > 0.05) in palm oil. The results of the present investigation depict that the AF extraction efficiency of MCNP depends on the type of vegetable oil and that MCNP could be a credible alternative for AF decontamination of the investigated vegetable oil.Keywords: aflatoxins, chitosan, contamination, nanoparticles, vegetable oils AbstrakArang aktif dan imarsil (adsorben lokal) mempunyai potensi dekontaminasi aflatoksin (AF) yang signifikan dalam minyak nabati dengan tingkat kontaminasi AF rendah, yaitu ≤ 9 ng/L. AF dalam minyak nabati dapat lebih dari seratus kali lipat tingkat kontaminasi tersebut. Oleh karena itu, penelitian potensi adsorben lain perlu dilakukan pada tingkat kontaminasi AF yang lebih tinggi. Penelitian ini menganalisis sintesis Magnetic Chitosan Nanoparticle (MCNP) dan efisiensi ekstraksi aflatoksin dari dua minyak nabati konsumsi (minyak inti sawit dan minyak sawit). Efisiensi ekstraksi minyak inti sawit dan minyak sawit pada tingkat pencemaran 579,6 dan 964,6 ng/L, MCNP masing-masing sebesar 82,80 - 100% dan 94,87 - 100%. Pembersihan aflatoksin total pada minyak sawit dan minyak inti sawit dapat terjadi pada suhu 30 °C dalam waktu masing-masing 30 dan 60 menit, pada kondisi optimal MCNP, yaitu 4,4 mg/L. Konsentrasi MCNP, suhu ekstraksi, dan waktu kontak signifikan (p < 0,05) pada minyak inti sawit, tetapi kondisi ini tidak signifikan (p > 0,05) pada minyak kelapa sawit. Hasil penelitian ini menunjukkan bahwa efisiensi ekstraksi AF MCNP tergantung pada jenis minyak nabati dan MCNP dapat menjadi alternatif untuk dekontaminasi AF dari minyak nabati yang diteliti.Kata kunci: aflatoksin, kitosan, kontaminasi, minyak nabati, nano partikel

Abstract

Abstract The efficacy of ImarsilTM in mitigating the effects of aflatoxin M1 (AFM1) in cow's milk on hematological and histopathological parameters was investigated in this study. Seventy-two albino rats were randomly allocated to four treatment groups A - D in a six-week study. Rats in all groups were fed standard ration. In addition, 2 mL of clean distilled water, 2 mL of milk, 2 mL of AFM1 contaminated milk (456 ng/L), and 2 mL of AFM1 contaminated milk (456 ng/L) treated with ImarsilTM at 2% dosage rate were added to the ration of animals in groups A, B, C, and D respectively. The results of the investigation showed that rats in Group C developed a significant (p<0.05) lower weight. Packed Cell Volume (%), Hemoglobin (g/dL), Red Blood Cell (106/mm3), Mean Corpuscular Volume (fL), Mean Corpuscular Hemoglobin (pg), and Mean Corpuscular Hemoglobin Concentration (g/dL) were not significantly different (p>0.05) among the different groups. In group C, a significant reduction (p<0.05) occurred in the white blood cell (103/mm3) (12.90 - 8.63), and lymphocytes (87.00 - 74.33%) counts while the neutrophils (%) increased from 13.00 to 25.67. In contrast to those in Group C, tissue sections from Group D showed no histological lesions. Therefore, ImarsilTM represents an effective and safe adsorbent for the remediation of AFM1-contaminated milk.Keywords: adsorbents, aflatoxin M1, cow’s milk, hematological parameters and histopathological changes, ImarsilTM AbstrakTingkat keberhasilan ImarsilTM dalam memitigasi efek aflatoksin M1 (AFM1) pada susu sapi terhadap parameter hematologi dan histopatologi diidentifikasi dalam penelitian ini. Tikus albino 72 ekor secara acak dibagi menjadi 4 kelompok perlakuan A, B, C, dan D dalam penelitian 6 minggu. Tikus pada semua kelompok diberi ransum standar. ImarsilTM dengan dosis 2%. dicampurkan pada 2 mL air suling bersih, 2 mL susu, 2 mL susu terkontaminasi AFM1 (456 ng/L), dan 2 mL susu terkontaminasi AFM1 (456 ng/L) kemudian ditambahkan pada ransum masing-masing hewan di kelompok A, B, C, dan D. Hasil penelitian menunjukkan bahwa tikus di Kelompok C mengalami penurunan berat badan yang signifikan (p<0,05). Packed Cell Volume (%), hemoglobin (g/dL), sel darah merah (106/mm3), Mean Corpuscular Volume (fL), Mean Corpuscular Hemoglobin (pg), dan Mean Corpuscular Hemoglobin Concentration (g/dL) tidak berbeda signifikan (p>0,05) antar kelompok yang berbeda. Kelompok C juga menunjukkan penurunan yang signifikan (p<0,05) pada jumlah sel darah putih (103/mm3) (12,90 - 8,63) dan limfosit (87,00 - 74,33%), sedangkan neutrofil (%) meningkat dari 13,00 menjadi 25,67. Berbeda dengan kelompok C, potongan jaringan pada kelompok D tidak menunjukkan lesi histologis. Oleh karena itu, Imarsil™ merupakan adsorben yang efektif dan aman untuk remediasi susu yang terkontaminasi AFM1.Kata kunci: adsorben, aflatoksin M1, ImarsilTM, parameter hematologi dan perubahan histopatologi, susu sapi
