“…Though at the time of modification, native starches are treated with some chemical or biological agents including acetic anhydride, sodium hypochlorite, sodium trimetaphosphate, ammonium chloride, monochloroacetic acid, hydrochloric acid, chloropropylene glycol, etc., these chemicals are not altogether safe for consumption and may have some harmful effects on human health. [236][237][238][239][240][241][242] However, the risks of prolonged use of these chemically modified starches are still unknown. The deep investigation of the safety profile of these modified starches is very crucial concerning the toxicological facet.…”

“…Salah satu contoh minyak nabati yang sering digunakan adalah minyak canola (Kong, Liu, and Curtis 2011), minyak jarak (Gama, Ferreira, and Barros-Timmons 2019) dan beberapa minyak hasil pirolisis tumbuhan (Özbay and Ayrilmis 2015;Xing et al 2018). Alasan penggunaan minyak nabati ini adalah banyaknya jumlah gugus karboksil yang dapat membentuk ikatan dengan tepung tapioka dan PVA (Gouater Issola et al 2018). Namun, penambahan minyak ini dapat berdampak terhadap turunnya daya rekat perekat.…”

Penelitian ini bertujuan untuk menganalisis karakteristik perekat alami dengan variasi agen crosslinker yang digunakan. Jenis agen crosslinker tersebut adalah asam sitrat dan asam oksalat yang memiliki kemampuan untuk berikatan dengan perekat tepung tapioka-PVA. Proses sintesis dari perekat dilakukan melalui tahapan gelatinisasi, hidrolisis, oksidasi, dan polimerisasi. Reaksi dijalankan dengan menggunakan labu leher tiga dan pengaduk merkuri pada suhu operasi 70 °C dan tekanan 1 atm. Karakteristik dari perekat seperti viskositas, kuat tarik kering dan basah, kandungan padatan, umur perekat, dan morfologi dianalisis dengan menggunakan standar yang telah ditentukkan. Hasil penelitian menunjukkan bahwa penggunaan agen crosslinker berupa asam sitrat memiliki pengaruh yang signifikan terhadap kualitas dari perekat. Asam sitrat dapat meningkatkan viskositas serta memperkuat kuat tarik kering maupun basah dari perekat. Nilai kuat tarik kering dan basah dari perekat ini adalah 1,0173 dan 0,7039 MPa. Penambahan asam sitrat berdampak terhadap peningkatan kekentalan perekat di setiap periode. Analisis morfologi menunjukkan bahwa penggunaan agen crosslinker berdampak terhadap tingkat homogenitas dari perekat. Dengan demikian dapat disimpulkan bahwa asam sitrat dengan persentase penambahan sebesar 2% dari berat tepung tapioka merupakan jenis agen crosslinker yang dapat meningkatkan kualitas dari perekat tepung tapioka-PVA.

“…Penggunaan minyak nabati sebagai zat aditif seperti minyak canola (Kong, Liu, & Curtis, 2011), minyak jarak (Gama, Ferreira, & Barros-Timmons, 2019) minyak biji rami (Addis, Koh, & Gordon, 2020) dan minyak hasil pirolisis dari tumbuhan (Özbay & Ayrilmis, 2015) menunjukan peningkatan kualitas sifat dari perekat. Peningkatan kualitas tersebut dikarenakan adanya reaksi antara gugus di dalam minyak nabati dengan tepung tapioka (Issola, Kamlo, Yona, & Ndikontar, 2018). Minyak nabati dengan harga yang murah dan mudah diperbarui memiliki banyak jenis gugus fungsi seperti alkohol, aldehid, karboksilat, ester, eter, furan, keton dan fenol berpeluang untuk dimanfaatkan sebagai pengganti bahan fosil dalam pembuatan perekat alami (Bridgwater, 2012).…”

The development of the quality of bioadhesive is an interesting subject to be studied. This study aims to improve the quality of starch-based bioadhesive using olive oil. The high content of phenolic functional groups makes an opportunity for olive oil to be used as an additive for adhesive. The bioadhesive was made by hydrolysis, oxidation, polymerization, and olive oil addition. The viscosity measurement, solid content measurement, dry and wet shear strength analysis were carried out to determine the quality of bioadhesive. The result showed that the viscosity of PA25% has increased compared to the viscosity of PA0%. The solid content and dry shear strength of the adhesive decreased along with the increase of olive oil. Polymerization reaction between MMA monomer and cassava starch as well as olive oil addition did not provide satisfactory adhesion strength.
