Factors affecting the formation of highly concentrated emulsions and nanoemulsions
(Elsevier, 2019-10-05)Highly concentrated (HC) emulsions and or submicron emulsions arise as an interesting strategy to encapsulate and transport labile lipophilic bioactive compounds such as curcumin to be further incorporated into food ... -
Characterization of Fungal Surface Contaminants of the Small Maltese June Pear, Pyrus communis var. bambinella
(International Association for Food Protection, 2020-08-01)Fungal pathogens cause surface contamination and potential premature fruit spoilage of bambinella, a fruit endemic to the Maltese islands, leading to the loss of fruit during the postharvest phase. The objective of this ... -
Protein/polysaccharide complexes to stabilize decane-in-water nanoemulsions
(Springer Science+Business Media, LLC, part of Springer Nature, 2020-01-30)Protein/polysaccharide complexes can be formed by electrostatic interactions and may be useful for enhancing the stability of nanoemulsions containing short-chain alkanes, which are highly prone to destabilization by Ostwald ... -
Design and characterization of corn starch edible films including beeswax and natural antimicrobials
(Springer Science+Business Media New York, 2017)The effectiveness of edible films (EFs) used as coatings to maintain the quality and safety of fresh produce for long time depends on their functional properties characterization. This study was aimed to design and evaluate ... -
Layer-by-layer assembly of food-grade alginate/chitosan nanolaminates: formation and physicochemical characterization
(Springer Science+Business Media New York, 2017)The alternate deposition of oppositely charged materials (layer-by-layer technique) is an effective approach to functionalize materials. Biopolymer-based nanolaminates obtained by the layer-by-layer technique can also be ... -
