Effect of refrigeration on anthocynin content of pomogranate arils when stored in different packaging material

Abstract

Pomegranate (Punica granatum) is a fruit that belongs to the family Lythraceae, subfamily Punicoideae. Pomegranates are a rich source of Anthocyanins, Vitamin C, Vitamin K, etc. Anthocyanins are naturally occurring compounds, members of the flavonoid groups of photochemical, involved in defense against the damaging effects of UV irradiation in plants and protect from many oxidants. They are common components of the human diet, as they are present in many foods, fruits, and vegetables, especially in berries and red wine. Anthocyanin belongs to the class of molecules called flavonoids synthesized via the phenylpropanoid pathway. They occur in all tissues of higher plants, including leaves, stems, roots, flowers, and fruits. Anthocyanin content in pomegranate arils decreases at a lower temperature. Compared to HDPE and PP, Anthocyanin content in metalized film decreases at a slower rate. There is an increase in TSS, Acidity, and Brix Acid ratio.
