Evaluation of antioxidant and antimicrobial properties of Physalis Alkekengi extract on edible fish cover

Today, petroleum-based plastic packaging is widely used in food storage, but their application has caused many environmental impacts of petroleum derivatives Countries should impose legal restrictions on the use of these packages. In this study, the film Activated biodegradable packaging based on gelatin of different concentrations (1, 2, 3 and 2/2%) Were. Features of active film produced such as water vapor permeability, light transmittance and anti-aging properties Its oxidant was investigated. Also the effect of gelatinous active film coating on increasing the shelf life of fish fillet. The chemical properties of fillets (volatile nitrogen base and Ph) were investigated. The results of this study showed that Addition of different concentrations of Physalis Alkekengi extract reduces water vapor permeability and film passage Jalettini activated. Also increasing the concentration of Physalis Alkekengi extract increased the antioxidant properties of the film Jalettini was produced. Investigation of fish fillet coated with active film containing the desired concentrations of the extract Concentration showed that increasing concentration of extract of cannabis significantly decreased the amount of volatile nitrogen compounds. From the activity of microorganisms (and ph. Thus, it can be stated that the active gelatin film contains Different concentrations of poppy extract have the potential to increase fish shelf life as one The film is biodegradable.
