Characterization of active paper packaging incorporated with ginger pulp oleoresin

Abstract

Abstract. Utilization of ginger pulp waste from herbal medicine and instant drinks industry in Indonesia currently used for fertilizer and fuel, whereas the ginger pulp still contains high oleoresin. Active paper packaging were developed incorporated with ginger pulp oleoresin (0%, 2%, 4%, and 6% w/w). Physical (thickness, tensile strength, and folding endurance, moisture content), sensory characteristics and antimicrobial activity of the active paper were evaluated. Selected active paper then were chemically characterized (functional groups). The additional of ginger pulp oleoresin levels are reduced tensile strength, folding endurance and sensory characteristic (color, texture and overall) and increased antimicrobial activity. Due to physical, sensory characteristic and antimicrobial activity, active paper with 2% ginger pulp oleoresin incorporation was selected. Characteristics of selected paper were 9.93% of water content; 0.81 mm of thickness; 0.54 N / mm of tensile strength; 0.30 of folding endurance; 8.43 mm inhibits the growth of Pseudomonas fluorescence and 27.86 mm inhibits the growth of Aspergillus niger (antimicrobial activity) and neutral preference response for sensory properties. For chemical characteristic, selected paper had OH functional group of ginger in 3422.83 cm -1 of wave number and indicated contain red ginger active compounds.

Impact of Ginger Root Powder Dietary Supplement on Productive Performance, Egg Quality, Antioxidant Status and Blood Parameters in Laying Japanese Quails

“…Throughout the production of ginger drink, powder, flakes and or ginger extract, significant amount of process discards, and byproducts are produced every year that could potentially be used as inexpensive feed additive in animal industry [ 18 , 19 ]. In a recent study, ginger supplement in broiler chicken diets stimulated the immune and digestive systems of the birds considerably [ 20 ].…”

Fabrication of 6-gingerol, doxorubicin and alginate hydroxyapatite into a bio-compatible formulation: enhanced anti-proliferative effect on breast and liver cancer cells

“…2c), peaks corresponding to –CH 2 stretching are clearly appearing at 2914 cm −1 and 2877 cm −1 . The rest of the peaks resemble the m-HAP spectrum with some additional peaks [49]: a small hump at 1719 cm −1 corresponding to –C=O stretching [26], and a few bands at 1398 cm −1 , 1247 cm −1 , 1110 cm −1 , and 891 cm −1 corresponding to aromatic C–H in-plane deforming and stretching, –C–O–C stretching, and –C–O stretching of –C–O–H bonds, respectively [50, 51].

PENGGUNAAN KERTAS AKTIF BERBASIS OLEORESIN AMPAS JAHE EMPRIT (Zingiber officinale var. amarum) TERHADAP KUALITAS BUAH STROBERI (Fragaria x ananassa) SELAMA PENYIMPANAN

“…Hasil uji kesukaan semua parameter menunjukkan panelis dapat menerima kertas aktif tersebut (bersifat netral). Hasil uji FTIR menunjukkan adanya senyawa aktif jahe pada pembuatan oleoresin berupa gingerol dan zingeron 10 . Gingerol bekerja aktif merusak membran luar dan membran sitoplasma dinding sel bakteri 11 .…”

“…Hal ini terjadi karena zat aktif yang terdapat pada kertas aktif oleoresin ampas jahe mampu menghambat pertumbuhan mikroba pada buah stroberi. Penghambatan mikroba tersebut berasal dari gugus aktif pada gingerol, zingeron, dan kitosan asetat 10 .…”
