The present study aimed at assessing the impact of addition of fumaric acid (0.5%), as an active agent, in a corn starch (2%) based edible coating, on the lipid quality and microbial shelf life of silver pomfret () fish steaks stored at 4 °C. Treating fish steaks with FA resulted in a bacteriostatic effect leading to reduced counts of total mesophilic and psychrotrophic bacteria, HS producing bacteria and . The total mesophilic bacterial count of uncoated control sample exceeded the permissible limit of 7 log cfu g on 6th day and had the lowest microbial shelf life. FA incorporation in the CS coating improved the microbial stability of fish steaks resulting in a shelf life of 15 days. The outcomes of the study suggest that CS based coating is beneficial in delaying lipid oxidation as displayed by the lower TBA and PV values while FA is an effective agent for further increasing the preservative action of CS coating by significantly inhibiting microbial growth as well as lipid quality deterioration, which could be exploited by the seafood industry as an active packaging component.

In this study, the nano chitosan particles were produced by ionotropic gelation between sodium tripolyphosphate and chitosan. The effect of nano chitosan with or without sodium lactate coating was evaluated on physicochemical (pH, thiobarbituric acid, total volatile basic nitrogen, and peroxide), microbial (total mesophilic and psychrotrophic viable counts, lactic acid bacteria, yeasts, and molds), and sensorial properties of beef burgers within 24 days of storage at 4°C. The solutions of 1% nano chitosan (T), 2% nano chitosan (T), 2.

The aim of this study was to investigate the effects of ultrasound at two different frequencies, namely 30 kHz and 42 kHz, on various aspects of industrial Iranian honey, including its physical, biochemical, antioxidant and antimicrobial properties. Samples were subjected to ultrasound treatment at 30 kHz or 42 kHz for a duration of 1, 5 or 10 minutes at temperatures of 20 °C or 45 °C, respectively. The following parameters were then evaluated on days 1, 30, 90, and 180: HMF content, pH, acidity, proline concentration, total number of aerobic mesophilic bacteria, diastase activity, moisture content, sucrose concentration, fructose concentration, glucose concentration, fructose- glucose ratio, ABTS (antioxidant activity) content, number of osmophiles, phenol concentration, reducing sugar concentration and total sugar concentration.

Analog processed cheeses are cheese-like products with diverse compositions and functional properties that are produced by replacing milk components with non-milk components. The aim of the study was to investigate physicochemical, rheological and sensory properties of cheeses and oleogels. The results showed; that increasing the concentration of Mono and di-glyceride increased the oil binding capacity and improved the characteristics of the oleogel texture and stable during storage, especially in terms of oxidative.

This study aimed to describe the morphological features and microstructure of the upper, lower, and third eyelids of the black-winged kite, Elanus caeruleus, and to characterize the organized lymphoid follicles and lymphocytes in the eyelid mucosa. Additionally, it aimed to illustrate the importance of the eye adnexa in the eye's immune protection. The upper, lower, and third eyelids display varying morphological differences that seem to be closely linked to the birds' way of life, indicating adjustments to their environment and eating behaviors.
