Summary Polyethylene terephthalate (PET) is one of the packaging materials that widely used for soft drinks. PET may contain acetaldehyde which a thermal degradation product, and hence migrate into product in package. In this study, migration from bottles drinks containing carbonic acid was determined by gas chromatography without headspace instrument. Carbonated beverage samples obtained four different firms following filling process were stored at 5, 20 40 °C 6 months analysed periodically...

In this study the combined effect of bay (Laurus nobilis L.) essential oil (0.5% v/w) with modified atmosphere (MAP) (20%CO2/80%N2) and vacuum packaging in ground chicken breast meat stored at 4°C was investigated. Microbial populations inoculated Listeria monocytogenes AUFE 39237 Escherichia coli total viable counts (TVC) were also monitored during 0,1,3,5,7 th days storage. MAP with/without gave significantly (p<0.01) higher reductions microbial populations. Vacuum combination found...

In this work, it was aimed to determine the effect of packaging technique on some quality properties "Crottin de Chavignol" type goat cheese packaged under vacuum (VP) and modified atmosphere (MAP) (%20 CO2 + %80 N2) during storage at 4°C also compare these two techniques be able more suitable for cheese. Sampling carried out physicochemical, microbiological, sensory textural analyses 1st day, 3rd, 6th, 9th,12th 15th weeks. Control cheeses which were atmospheric air unacceptable sensorially...

Abstract This study aimed to determine the effects of carbon dioxide concentration in modified atmosphere packaging (MAP) on quality criteria and shelf life whole wheat flour bread. Four different concentrations CO 2 N gases (30% + 70% , 50% :30% 100% ) were applied bread samples, which packaged with PA/EVOH/LDPE (polyamide/ethylene vinyl alcohol/low‐density polyethylene). The samples stored at room temperature (25°C ± 1°C) for 13 days. control group was using BOPP (bi‐oriented...

Research background. Artichoke leaves, an important waste product of the food industry, have antioxidant and antimicrobial capacity. Although there are several studies in literature to determine their activity, a comparison green extraction technologies including microwave, ultrasound probe bath methods relation maceration technique has not been performed. Also, parameters such as temperature, power, mode time for obtaining targeted compounds highest amount. For this reason, we aimed compare...

This study aims to optimize the extraction conditions obtain highest yield, characterize tomato peel extract (TPE) under optimized conditions, and also determine effect of ambient oxygen on properties TPE. Optimisation were performed at three temperatures (60 °C, 80 100 °C) periods (2, 4, 6 h) by response surface methodology. The atmospheric oxygen-free (AC, OFC) analysed whether characteristics both extracts changed depending presence oxygen; moreover, morphological, chemical, thermal,...

With the increasing world population, food need of humanity is proportionally. Agricultural wastes constitute an important potential for global economy as they contain components that are less preferred to be consumed due their low bioavailability indigestion in human body or sensory properties, but may beneficial health such antioxidant substances and antimicrobial agents. The benefits using these terms reducing environmental pollution obvious. Tomato, which one most used agricultural...

Bisphenol-A (BPA) which is a plastic monomer acting as endocrine disruptor, can cause developmental effects and change the metabolism even at low concentrations.This study was carried out to make (i) general assessment by performing residue analysis on polycarbonate baby bottles, (ii) determining factors affecting migration of BPA food (iii) effect repetitive procedures PC bottles in daily use.Amount residual ranged from 0.60 ±0.05 ppm 6.23 ±0.24 could not be detected any contact...

Abstract The effect of oxygen permeability packaging material on shelf life minimally processed and passive modified atmosphere packaged pomegranate arils, cv “Wonderful” as well some quality attributes were investigated. Packaging materials having Oxygen transmission rate (OTR) low 125–290 cm 3 /m 2 /day found to provide the gas concentration requirements 2–5% O 3–10% CO for application fresh fruits vegetables. Although color, firmness, anthocyanin, total phenolic content sensorial...

Polycarbonate (PC) materials are widely used for the packaging of drinkable water. The use PC as food raises some concerns migration Bisphenol A (BPA), which is monomer PC. Therefore, in this research, it was aimed to determine quality new and old (life time ended) water carboys terms residual BPA levels with respect storage conditions. For purpose, determined by storing at three different temperatures (5, 20 40C) seven times (1., 5., 10., 20., 30., 45. 60 days.) Residual migrated were High...

Tavuk eti yüksek protein ve nem içeriği nedeniyle hem mikrobiyal de biyokimyasal bozulmalara oldukça açık olmasından dolayı raf ömrü kısa olan bir gıdadır. Ayrıca gerek gıdanın doğası işleme koşulları patojen mikroorganizmalarla kontamine olma ihtimalinden taze tavuk etinin güvenilir şekilde üretimini arttırmak son tüketiciye ulaşana kadar israf olmasını önlemek amacıyla güvenilirliğini sağlamak önemlidir. Taze etlerinde koruyucu katkı maddeleri ilavesi, ısıl işlem uygulamaları ve/veya...

Fresh mushrooms have a very short shelf life, of 1 – 3 days because their high respiration rate and lack cuticles that protect the plant from external factors. In case fresh-sliced mushrooms, they will be more susceptible to spoilage reactions due increase in as result broader surface area. Conventional packaging materials can not meet requirements for modified atmosphere mushrooms. One techniques extend fresh-cut produce life is passive modification technology. For highly respiring such...

Fresh-cut fruits and vegetables have longer shelf lives when appropriate packaging materials having proper permeability properties are used. For this reason eight different were used it was aimed to determine the material analytical mathematical of fresh cut red cabbage. Head space analysis, microbiological sensorial analysis together with pH, weight loss (%) colour performed. As a result study, determined that low density polyethylene (LDPE) film 20 µm thickness 12276 cc/m2-day oxygen as...
