The present study aimed at development of finger millet-based functional beverage mix with 9% green banana flour and 1% ginger powder. The developed beverage mix was packed by using four different packaging materials i.e., low-density polyethylene (P1), standup pouch (P2), aluminium foil pouch (P3) and polyethylene terephthalate bottles (P4) and stored at room temperature. The changes in the physico-chemical, microbial quality were analyzed for 3 months (90 days). The results revealed that during storage, the moisture content was increased from 6.23 to 6.99%, whereas other chemical properties viz., carbohydrate (CHO), protein, fat, ash and dietary fiber were gradually decreased from 68.62 to 68.48, 15.09 to 14.99, 1.50 to 1.48, 3.74 to 3.73 and 2.78 to 2.77 respectively. There was no signifance change in calcium and phosphorus among the packaging materials during storage. The microbial load was low in P3 and P4 packed beverage mix during storage. The functional beverage mix packed in polyethylene terephthalate bottles was undergone minimum changes in physico-chemical characteristics. Hence, it is concluded that the storage of functional beverage mix in polyethylene terephthalate bottles extended the shelf life of the product and reduced the nutrient losses during storage.

Food Input

Polyethylene terephthalate (PET) is one of the main packaging materials for beverage bottles. Even if this polymer is good to recycle, mechanical recycling processes need a well-sorted input fraction. For less-sorted PET packaging, or even non-food input sources, chemical recycling seems to be a solution to increase PET recycling. For post-consumer recyclates in packaging applications, it is essential that the safety of the recyclates is guaranteed, and the consumers’ health protected. For mechanical recycling processes, evaluation criteria are already established. For chemical recycling processes, however, such evaluation criteria are only roughly available. This study evaluated the safety of the chemical recycling process similar to the approach of the European Food Safety Authority (EFSA). However, due to the lack of information about the contamination level of the input materials for the chemical recycling process, the evaluation was adapted. In addition, the evaluation should be performed separately for the depolymerisation and for the repolymerisation steps. However, due to the high cleaning efficiencies of both steps, the evaluation can focus on the repolymerisation. This simplifies the assessment of the chemical recycling processes considerably.

Today, the scientific community is facing crucial challenges in delivering a healthier world for future generations. Among these, the quest for circular and sustainable approaches for plastic recycling is one of the most demanding for several reasons. Indeed, the massive use of plastic materials over the last century has generated large amounts of long-lasting waste, which, for much time, has not been object of adequate recovery and disposal politics. Most of this waste is generated by packaging materials. Nevertheless, in the last decade, a new trend imposed by environmental concerns brought this topic under the magnifying glass, as testified by the increasing number of related publications. Several methods have been proposed for the recycling of polymeric plastic materials based on chemical or mechanical methods. A panorama of the most promising studies related to the recycling of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), and polystyrene (PS) is given within this review.

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
