Sugarcane molasses is defined as a product obtained from the concentration of sugarcane juice. This product is accepted in the Egyptian market and can be used as a sweetener instead of refined sugar. The packaging materials and storage temperature affect the quality properties of the sugarcane molasses. In this study, the sugarcane molasses was packed in four different packaging materials (glass jars, pottery pitchers, plastic jars, and tin containers) and stored at two different temperatures (20 and 40oC) to study the quality properties. The changes in the physicochemical, antioxidant activity and sensory properties were estimated at periodic intervals of 60 days during the period of storage study (12 months). The results showed that, pH, total soluble solids, moisture, total sugars, antioxidant activity, flavor and overall acceptability score of stored sugarcane molasses were reduced significantly (p≤0.05) with the progression of the storage period. The stability of packed samples stored at 20°C was better, as the highest values of all studied quality traits were recorded compared to their counterparts at 40°C. Among the studied packaging materials, sugarcane molasses filed in glass jars with metallic covers, and pottery pitchers with sterilized tampons had the best quality properties. Final of storage period, the glass jars recorded the highest values of total soluble solids, moisture and total sugars. While pottery pitchers were better for pH, antioxidant activity, flavor and overall acceptability score. These results may come from the physiochemical properties of the raw materials of the pottery pitchers.
Sugarcane molasses is a nutritious beverage with a black color, characterized by its viscosity, distinctive taste and aroma, which makes it a unique food with high nutritional value. The quality characteristics of sugarcane molasses stored inside various packaging materials at different storage periods were evaluated. The evaluation included the determination of the physicochemical properties of sugarcane molasses stored in four types of packaging materials (glass jar, pottery pitcher, plastic jar and tin container). The stored sugarcane molasses were analyzed periodically at 2, 4, 6, 8, 10 and 12 months for the optical density (at 420 nm), acidity, viscosity values and total phenol content. All studied physicochemical properties increased significantly (p≤0.05) with increasing storage time, the results showed that pottery pitchers and glass jars are suitable for packaging sugarcane molasses. They produce the most stable sugarcane molasses, so they are practical containers to use. Therefore, it is recommended to use this type of packaging materials with care of the storage temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
