Gummy candy, a popular confectionery, requires appropriate packaging to maintain its quality and extend its shelf life. One crucial aspect of packaging is its barrier properties, particularly moisture resistance, which prevents the candy from becoming stale or sticky. This article explores the testing methods and results for evaluating the moisture resistance of gummy candy packaging materials.
The shelf life of gummy candy is influenced by various factors, including the moisture content of the candy itself and the barrier performance of its packaging. Sugar, a primary ingredient in gummy candy, acts as a natural preservative, inhibiting microbial growth. However, improper storage can still lead to issues like mold, oxidation, and deterioration.
To counteract these challenges, gummy candy packaging must effectively prevent the penetration of moisture and oxygen. This helps maintain the candy's texture, flavor, and appearance throughout its shelf life.
To assess the moisture resistance of gummy candy packaging materials, a water vapor transmission rate (WVTR) test is commonly employed. This test measures the amount of water vapor that passes through a given area of the material over a specific time period.
The cup method, which conforms to ASTM E96 standards, is often used for WVTR testing. This method involves placing a desiccant within a sealed chamber and measuring the weight gain over time as water vapor permeates the material.
For this study, Labthink C360M Water Vapor Transmission Rate Test System was used. This instrument, independently developed and produced by Jinan Labthink Instruments Co., Ltd., offers precise control over temperature, humidity, air velocity, and other relevant parameters.
The WVTR of the front and back composite film materials used in gummy candy packaging was evaluated. Multiple specimens were tested, and the average WVTR was calculated for each side.
The results indicated that the moisture resistance of the front and back materials differed. The back material exhibited significantly better moisture resistance than the front material. This finding highlights the importance of considering both sides of the packaging when assessing its overall barrier properties.
The moisture resistance of gummy candy packaging is a critical factor in maintaining product quality and extending shelf life. By conducting WVTR tests, manufacturers can evaluate the effectiveness of their packaging materials in preventing moisture penetration. This information can be used to optimize packaging design and ensure that gummy candy reaches consumers in optimal condition.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
