Effects Of Period And Temperature On Quality And Shelf-Life Of Cucumber And Garden-Eggs Packaged Using Cassava Starch-Zinc Nanocomposite Film, Adeshina Fadeyibi, Zinash Delebo Osunde, Mohammed Gana Yisa

Journal of Applied Packaging Research

Nanocomposite film can be used to prolong the shelf-life of fruits and vegetables. This research was undertaken to investigate the effects of packaging period and temperature on the quality and self-lives of cucumber and garden-eggs packaged using cassava starch-zinc nanocomposite film. Hundred grams each of cucumber and garden-eggs were wrapped in a 200× 350 mm size nanocomposite film and low density polyethylene (LDPE) of 2.240± 1.076 × 10^-10 gm^-1Pa^-1s^-1 water vapor and 1.568± 0.084× 10^-10 gm^-1Pa^-1s^-1 oxygen gas permeability. The products were stored at 10−27^oC temperatures …

Moisture Sorption Behavior And Shelf Life Prediction Of Teff Seed And Flour, Baba Abdissa, Rudrayya Math, Kodandaramreddy Desham, Srinivasulu Korra

Journal of Applied Packaging Research

Moisture sorption isotherms of Teff seed and its flour were determined over the range of relative humidity (11–92%) using a gravimetric technique at constant temperature (27°C). The results obtained showed that the moisture sorption isotherm of both is almost similar and sigmoid with increasing equilibrium water content at the constant temperature. The curves start raising high above 64% RH indicating the products deteriorates faster above 64% RH. Hence the moisture content equilibrating to 64% RH was taken as critical for both Teff seed and flour variants. The sorption isotherm fits the GAB equation as per GAB generalized equation for sorption …

Combined Effects Of Calcium Ascorbate Treatment And Modified Atmosphere Packaging To Improve Quality Retention Of Fresh-Cut Cantaloupes, Joongmin Shin, Kevin Mis Solval, Bob Xiang, Youn Suk Lee

Journal of Applied Packaging Research

The impact of passive modified atmosphere packaging technique (MP) and calcium ascorbate (CA) on the extension of freshness and shelf life in fresh-cut cantaloupe was studied at two storage temperatures (4 and 10°C). Fresh cantaloupes were cut into uniform size cubes (25.4 mm x 25.4mm x 25.4mm). Then, half of the fresh cut cubes was dipped into the treatment solution, and the others were not. Clamshell tray with snap-on lid (control) and micro-perforated sealable lid (MP) was used as the fresh cut fruits packaging. Fresh cut cantaloupes in CA and MP combination (CA-MP) observed the highest quality preservation among the …

Computerized And Electronic Controls In Food Packaging, Anjali Srivastava, Vivek Kumar, Alak Kumar Singh

Journal of Applied Packaging Research

The focus of food packaging is to contain food in a cost-effective way that satisfies industry requirements and consumer desires, maintains food safety and minimizes environmental impact. Currently, with the increasing demand of the consumers the major concern of food packaging industry is on efficiency of the plant process, productivity, quality as well as safety. It becomes necessary for companies to discover ways to improve their productivity in terms of maintaining safety, using sustainable materials in packaging, implementing flexible and standardized technology, and maintaining good quality of foods. Thus, to achieve the required demands, automation and upgradation of the packaging …

Developments And Properties Of Plastic Mimicking Biopolymers For Food Packaging Application, Daniel I. Hefft

Journal of Applied Packaging Research

Sustainability takes an ever increasing importance in the food industry. Here not only the selection of raw materials plays a role, but also packaging materials. Nowadays there is an increasing number of biodegradable and bio-compostable packaging materials available.

However, these materials are still not able to replace mineral oil based packaging materials completely, nevertheless they are becoming increasingly important, since there must be solutions to problems such as pollution of the oceans by plastic waste, growing piles of rubbish from growing population, etc.

The following literature review shows briefly recent developments on plastic mimicking biopolymers, as these materials guarantee great …

Predictive Modeling Of Oxygen Transmission Through Micro-Perforations For Packaging Applications, Ayman Abdellatief, Bruce A. Welt, Jason Butler, Eric Mclamore, Arthur Teixeira, Sanjay Shukla

Journal of Applied Packaging Research

Methods for creating precise perforations in respiring produce packaging are being increasingly adopted. Knowledge of oxygen transfer through perforated packaging and oxygen distribution in packages is necessary for successful packaging design of fresh produce. An approach to modeling perforated packaging performance was developed using a cylindrical chamber with precision perforations using Fick’s second law. The model was simulated using two techniques including Finite Element Method (FEM) using commercially available software and Finite Volume Method (FVM) through programming. Perforations were approximated as a source term in the second method. Both simulation techniques showed trends similar to experimental data.
