The aim of this work was to investigate the effect of almond gum as dietary fibre source in enhancing the wheat bread quality. Different amounts of almond gum (2%, 5% and 10% (w/w)) were used in bread formulation. The volume, texture, crust and crumb colour, as well as the sensorial properties, were evaluated and compared to control (without almond gum). The obtained results showed that almond gum addition enhanced significantly the volume of bread. The highest volume was obtained using 2% almond gum concentration with 23.6% increase, compared to control. Using almond gum in bread formulation improved considerably its texture with a notable decrease in hardness by 61.7% and 42.5% when using 2% and 5% almond gum, respectively. The sensory analysis scores showed that the better overall acceptability was found for breads supplemented with 2% almond gum, as compared to control and breads supplemented with 5% or 10% almond gum. 相似文献

There is an increase in consumer demand for plant-based alternatives to common food products. A critical segment of the food industry is the dairy market, where milk alternatives are becoming the choice of many people throughout the world. Consumers purchase milk alternatives as they provide an environmentally friendly and healthier option than cow’s milk. The beef and cattle industry's negative impact on the environment has been well reported. The cattle industry accounts for almost 3% of the overall greenhouse gases emitted each year in climate change. This study analyses the life cycle assessment for the cradle-to-retail system in the production of oat-based milk in Ecuador. Importing the oat was considered, and a techno-environmental perspective was applied to the system modelling. It introduces oat milk as a new alternative to plant-based beverages. Soy and almond milk are compared as established options in the market. Results showed better environmental performance from the oat beverage when compared to the traditional cow’s milk (+80% lower GHG emitted). Also, it can be established as a competitor for plant-based alternatives. For instance, it requires significantly less water consumption than almond milk. The oat-milk beverage has a better environmental performance than the traditional cow milk-based options. 相似文献
