Aloe-Based Edible Coating to Maintain Quality of Fresh-Cut Italian Pears (Pyrus communis L.) during Cold Storage
2021
Pear fruits are known for their antioxidant and nutritional characteristics. However, they are very susceptible to rapid decay. Edible coating (EC) represents a good strategy to maintain postharvest quality. The effects of two EC in slowing down the senescence processes in fresh-cut ‘Coscia’ pears were investigated: EC1 (A. vera gel, hydroxypropyl-methylcellulose and pomegranate seeds oil (PSO), EC2 (A. vera gel and hydroxypropyl-methylcellulose). Weight loss, firmness and colour decrease more slowly in both EC-treated than in untreated (CTR) slices; soluble solid content increases faster in CTR, indicating a faster ripening process. The specific investigation of undesired microorganisms di…
Effect of Three Different Aloe vera Gel-Based Edible Coatings on the Quality of Fresh-Cut “Hayward” Kiwifruits
2020
In recent years, the market for minimally processed fruit has increased. Fresh-cut fruits are characterized by a short shelf life due to the processing phases that accelerate the ripening courses. The aim of this work is to analyze the effect on the quality of fresh-cut Hayward kiwis of three different edible coatings based on (1) Aloe vera gel, (2) Aloe vera gel + hydroxypropyl methylcellulose and (3) Aloe vera gel + lemon essential oil. Fruit firmness, weight loss, color, soluble solids content, titratable acidity, microbial load and sensory analysis were evaluated as fresh after 2, 4, 7 and 10 days. Aloe vera gel and Aloe vera gel + lemon essential oil maintained the best values, as they…
Reduction of saturated fat in chocolate by using sunflower oil-hydroxypropyl methylcellulose based oleogels
2021
The suitability of sunflower oil-hydroxypropyl methylcellulose (HPMC) based oleogel obtained by emulsion template approach as partial cocoa butter (CB) replacer in chocolates was investigated. A level of 50% CB replacement was optimum, as higher level of replacement affected the sensory appearance in comparison to the control chocolate (without added oleogel). Four levels of HPMC (0.5, 1, 1.5 and 2%) were considered. Textural and calorimetric properties, as well as sensory properties obtained by Free Choice Profile of the formulated chocolates were investigated. Partial replacement of CB by the sunflower-HPMC based oleogel reduced significantly the chocolate hardness. Higher HPMC concentrat…
