Estimasi Risiko Migrasi Bisfenol A (BPA) Dari Kemasan Logam Pangan Olahan Di Indonesia

Logam merupakan salah satu jenis kemasan pangan yang banyak digunakan, untuk mencegah korosi. Logam biasanya dilapisi dengan pelapis epoksi resin seperti bisfenol A (BPA). BPA dapat mempengaruhi sistem endokrin dan dapat menyebabkan kerusakan pada berbagai jaringan serta organ. Penelitian ini bertujuan untuk mengetahui kandungan migrasi BPA pada kemasan kaleng sarden dan kornet serta paparannya pada penduduk Indonesia. Sampel yang digunakan adalah kemasan kaleng kosong untuk sarden dan kornet masing-masing 12 buah kemudian dianalisis menggunakan HPLC-UV Vis. Hasilnya menunjukkan bahwa konsetrasi migrasi BPA dalam kemasan kaleng sarden (menggunakan simulan etanol 20%) berkisar antara 0,005 – 0,05 mg/kg. Sedangkan dalam kemasan kaleng kornet (menggunakan simulan etanol 10%) sebesar 0,005 mg/kg. Rerata estimasi paparan perhari migrasi BPA dari konsumsi sarden dalam kaleng tertinggi terdapat pada usia 24-59 bulan yaitu 0,0546 µg/kgBB, sedangkan estimasi paparan perhari migrasi BPA dari konsumsi kornet dalam kaleng tertinggi terdapat pada usia anak 5-12 tahun yaitu sebesar 0,0066 µg/kgBB.  Nilai risiko P95 untuk paparan migrasi BPA dari konsumsi sarden dalam kaleng pada seluruh kelompok usia sebesar 2,3883% sedangkan nilai risiko paparan dari konsumsi kornet dalam kaleng pada seluruh kelompok usia sebesar 0,3846%. Nilai risiko tersebut tidak melebihi asupan harian yang dapat ditoleransi sementara (tTDI), yang mengindikasikan bahwa paparan migrasi BPA melalui kemasan kaleng sarden dan kornet akibat mengkonsumsi sarden dan kornet tidak menimbulkan risiko bahaya terhadap kesehatan manusia di Indonesia.Metal is one type of food packaging that is widely used. To prevent corrosion, metals are usually coated with an epoxy resin coating such as bisphenol A (BPA). BPA consumption can affect the endocrine system and cause damage to various organs. This study aims to determine the BPA migration in sardines and corned beef cans and its exposure to Indonesian consumers. The samples used were empty cans for sardines and corned beef, 12 each, and then analyzed using HPLC-UV Vis. The results showed that the migration concentration of BPA in sardines cans (using a 20% ethanol simulant) ranged from 0.005 – 0.05 mg/kg, while in corned beef cans (using 10% ethanol simulants) is 0.005 mg/kg. The highest average estimated daily BPA migration exposure of canned sardines consumption is at the age of 24-59 months (0.0546 µg/kg BW), while the highest estimated daily migration of BPA exposure of canned corned beef consumption is at the age of 5-12 years (0.0066 µg/kg BW). It also shows P95 risk value for exposure to BPA migration from consumption of canned sardines in all age groups is 2.3883%, while canned corned beef in all age groups is 0.3846%. These do not exceed the temporarily tolerable daily intake (tTDI) which indicates the exposure to migration of BPA from cans of sardines and corned beef due to consumption of sardines and corned beef does not pose a risk of danger to human health in Indonesia

Potential of salak (Salacca sumatrana) peel extract as a reducing agent for silver nanoparticle synthesis

Salak peel extract has a potential to be used as a natural reducing agent in the synthesis of silver nanoparticles (AgNPs). The salak peel (SP) used contained 0.082 and 0.031 % on a dry basis of phenolic and flavonoids compounds,  respectively. AgNPs were synthesized by reacting AgNO3 1 mM with the SP extract; with and without heating at 60oC for 10 minutes; followed by incubation for 1 to 6 days at room temperature. The addition of NaOH as a catalyst agent was also evaluated. Surface Plasmon Resonance (SPR) spectra patterns were observed using UV-Vis spectrophotometer. The resulting silver nano colloid exhibited an SPR spectrum in the wavelength range 400 – 450 nm. The absorbance value of the SPR spectrum increased temperature, alkali, and increased amount of SPE (Salak Peel Extract). FTIR spectra confirmed that the phenolics and flavonoids in the salak peel become the major component of  reducing compounds in forming AgNPs. This study proves the chemical components of SP that are potentially used as bio-reductor of AgNP synthesis

Karakteristik Edible Film dari Pektin Hasil Ekstraksi Kulit Pisang

Banana peel is a waste of banana processing industries which is obviously uneconomy and unfriendly to the environment. However, this material could be used as a source of important natural compounds, such as pectin. Owing to the fact that pectin has good gelling properties, it can be used to make edible film. The objectives of this research were to extract and characterize pectin from banana peel and to make edible film from the obtained pectin by using glycerol as plasticizer. Characterization of edible films were conducted in terms of color, thickness, elongation, tensile strength and water vapor transmission. The research used factorial completely randomized design. The results showed that yield of pectin made from ambon banana peel ripeness level one was 8.42% with the characteristics werewater content : 11.27% (<12%), ash content : 1.70%, low methoxil content : 4.15% (<7%) and galacturonat content : 25.86% (65%). The addition of glycerol significantly increased elongation and decreased tensile strength of edible film. Based on edible film result, the recomended treatment is the addition with glycerol 20% as plasticizer of pectin based edible film. Keywords : banana peel,pectin,edible film

Integration of ISO 22000 (2018) and HAS 23000 through Management System Audit: Case Study in Corned Beef Producer

Integrated Management System (IMS) based audit can assist the internal and external auditor to conduct an audit effectively and efficiently while checking compliance of Food Safety Management System and Halal Assurance System in the food industry. Corned beef is a product categorized as critical both in terms of halal and food safety. Implementing a food safety management system and halal assurance in corned beef industries is a challenge for producers and external auditors from inspection agencies. Based on the requirements equality approach, an Integrated Management System can be developed, referring to ISO 22000 : 2018 and HAS 23000. This research aims to combine the requirements of ISO 22000 : 2018 and HAS 23000 to be used for audit activity, as well as formulating recommendations for the corned beef producers in both requirements based on a new version of ISO 22000 : 2018. According to the analysis of requirements equality on each requirement objective, there are 14 of 30 sub-clauses of ISO 22000 : 2018 that can be integrated with 9 HAS criteria. There are 2 HAS criteria that cannot be integrated with sub clauses of ISO 22000 : 2018, namely criteria number 4 material and 5 product. When the IMS clauses are used in audit to one of corned beef company, the percentage of compliance with the IMS requirements is 90.6% in PT XYZ. The nonconformities related to ISO 22000 : 2018 found on a new clause that has not existed in the previous version ISO 22000: 2005. This gap creates some recommendations for PT XYZ. However, IMS based audit makes the audit for halal and food safety compliance be more effective that can combine checking of food safety and halal in one audit. Furthermore, IMS based audit makes the audit be more time efficient, by reducing the mandays
