In order to avoid the phase separation of the high density-polyethylene modified asphalt, a composite material modifier was prepared in the melt blending process with High density-Polyethylene (HDPE) and Styrene-butadiene-styrene (SBS) and a filler of Carbon black (CB). The storage stability of composite material (HDPE-SBS) modified asphalt was investigated by hot storage stability test and optical microscopic observation. The storage-stable mechanism of HDPE-SBS modified asphalt was analyzed also. The experimental results indicated that the difference of the softening point after storing at high temperature for 48h was very small. Micrographs of HDPE-SBS modified asphalt demonstrated that HDPE-SBS composite modifier particles dispersed uniformly and compactly and there were no obvious phase separations in the modified asphalt within a certain CB content range.

Roadway Construction

Utilizing polymers for asphalt concrete (AC) mixture modification has many drawbacks that hinder its wide implementations for roadway construction. Recently, research on employing complementary materials, such as nanomaterials, to balance negative impacts of polymers while enhancing the AC mixture’s performance has received great attention. This study aimed to investigate the effect of incorporating nanoclay (NC) particles on the performance of a high-density polyethylene (HDPE)-modified AC mixture. A 60/70 asphalt binder was first modified with HDPE, and then NC particles were gradually added at a concentration of 1–4% by weight of the asphalt binder. The binders’ physical characteristics, storage stability, and chemical change were scrutinized. AC mixture performance, including pseudo-stiffness, moisture damage resistance, stripping susceptibility, and rutting tendency, was investigated. A statistical analysis on the experimental results was conducted using Kruskal–Wallis and Dunn tests. Test results showed that employing NC/HDPE significantly increased penetration index and thereby enhanced binder temperature sensitivity. Moreover, it prevented oxidation action and separation and, therefore, enhanced binder storage stability. Furthermore, incorporating NC amplified pseudo-stiffness and significantly improved resistance against moisture damage and stripping of HDPE-modified mixtures. Moreover, it improved both elastic (recoverable) and plastic (unrecoverable) deformations of mixtures. The most satisfactory results were attained when incorporating 3% of NC.

Sensory quality and vitamin A retention in chin-chin stored using different packaging materials were evaluated. The Orange Fleshed Sweet Potato (OFSP) and Red Bambara Groundnut (RBG) flours were blended in ratio 50:50 for chin-chin production. Sensory quality, β-carotene and vitamin A contents of the chin-chin were analyzed using standard methods. Storage stability test of β-carotene and vitamin A retention were investigated using plastic bottles, high and low densities polyethylene packaging materials at ambient conditions (29.95±5.00°C, relative humidity 68.32±3.55%). The total vitamin A µgRAE retention in the chin-chin was estimated every week for four weeks and after twelve months. Moisture was least absorbed by chin-chin packaged in plastic bottles. The Vitamin A retentions were about 80 percent, 74 percent and 72 percent for plastic bottles, high density polyethylene and low density polyethylene, respectively after twelve months of storage. Texture, taste and overall acceptability were better retained when packaged in either plastic bottles or high density polyethylene. The chin-chin produced was able to store for up to twelve months when packaged in plastic bottles or high density polyethylene.

ABSTRAK Pengemasan minyak nabati dan produknya seperti minyak goreng, minyak untuk salad, margarin, dan shortening bertujuan untuk melindungi minyak agar dapat menjangkau konsumen secara aman, sehat, dan tanpa mengurangi kualitasnya. Artikel ini bertujuan untuk mengulas jenis bahan kemasan untuk minyak nabati, aspek perlindungan bahan kemasan terhadap mutu minyak, dan migrasi bahan kemasan ke dalam produk minyak. Bahan kemasan yang umum digunakan untuk mengemas minyak nabati dan produknya adalah kaca, baja, pelat timah, dan bahan plastik seperti polyvinylchloride (PVC), polyethylene terephthalate (PET) dan high density polyethylene (HDPE). Bahan-bahan kemasan tersebut memiliki keunggulan dan kelemahan dalam pengemasan minyak nabati yang tergantung pada fungsinya agar mutu minyak stabil selama distribusi dan penyimpanan. Faktor-faktor yang memengaruhi stabilitas minyak dalam kemasan meliputi faktor internal (komposisi asam lemak dan komponen minor pada minyak nabati) dan faktor eskternal (oksigen, cahaya, suhu, dan waktu penyimpanan). Pemilihan bahan kemasan juga harus mempertimbangkan keamanan minyak dari kontaminan akibat migrasi dari bahan kemasan. Migrasi bahan kemasan dipengaruhi oleh jenis minyak, di mana migrasi total bahan kemasan sedikit lebih tinggi pada minyak yang mengandung asam lemak rantai pendek dan asam lemak tidak jenuh pada jumlah tinggi. kata kunci: kemasan, migrasi, minyak nabati, mutu, plastik ABSTRACT The packaging of vegetable oils and their products such as cooking oil, salad oil, margarine, and shortening aims to protect the oil from reaching consumers safely, healthily, and without reducing its quality. This article reviews the packaging materials types for vegetable oils, protection aspects of packaging material to oil quality, and packaging materials migration into oil products. Packaging materials commonly used to package vegetable oils are glass, steel, tin plates, and plastics such as polyvinylchloride (PVC), polyethylene terephthalate (PET), and high-density polyethylene (HDPE). Packaging materials have advantages and disadvantages in the packaging of vegetable oils depend on their functions, so the oil stable during distribution and storage. Factors that influence the package’s oil stability cover internal factors (fatty acid composition and minor components of vegetable oils) and external factors (oxygen, light, temperature, and storage time). Packaging material elections must also consider oil safety from contaminants due to packaging material migration. Packaging materials migration is also influenced by the type of oil, where packaging materials total migration is slightly higher in oils containing short-chain fatty acids and unsaturated fatty acids at high amounts. keywords: packaging, migration, vegetable oil, quality, plastic

AbstractHAPEXTM (40 vol% hydroxyapatite in a high-density polyethylene matrix) and AWPEX (40 vol% apatite-wollastonite glass ceramic in a high density polyethylene matrix) are composites designed to provide bioactivity and to match the mechanical properties of human cortical bone. HAPEXTM has had clinical success in middle ear and orbital implants, and there is great potential for further orthopaedic applications of these materials. However, more detailed in vitro investigations must be performed to better understand the biological interactions of the composites and so the bioactivity of each material was assessed in this study. Specifically, the effects of controlled surface topography and ceramic filler composition on apatite layer formation in acellular simulated body fluid (SBF) with ion concentration similar to those of human blood plasma were examined. Samples were prepared as 1 cm × 1 cm × 1 mm tiles with polished, roughened, or parallel-grooved surface finishes, and were incubated in 20 ml of SBF at 36.5 °C for 1, 3, 7, or 14 days. The formation of a biologically active apatite layer on the composite surface after immersion was demonstrated by thin-film x-ray diffraction (TF-XRD), environmental scanning electron microscopy (ESEM) imaging and energy dispersive x-ray (EDX) analysis. Variations in sample weight and solution pH over the period of incubation were also recorded. Significant differences were found between the two materials tested, with greater bioactivity in AWPEX than HAPEXTM overall. Results also indicate that within each material the surface topography is highly important, with rougher samples correlated to earlier apatite formation.
