Cross-linked coacervates of cashew gum and gelatin in the encapsulation of pequi oil Ciência Rural
Alexandre,Joana de Barros; Barroso,Tiago Linhares Cruz Tabosa; Oliveira,Marília de Albuquerque; Mendes,Francisco Rogênio da Silva; Costa,José Maria Correia da; Moreira,Renato de Azevedo; Furtado,Roselayne Ferro.
ABSTRACT: Pequi oil is rich in bioactive compounds which can be encapsulated to increase protection against extrinsic environmental factors. A delayed degradation of pequi oil may occur by using microencapsulation technology, in addition to masking unpleasant flavors and aromas. Complex coacervation is a technique based on the electrostatic interaction between two oppositely charged biopolymers which form a matrix complexed around an agent of interest. However, cross-linking the particles is often necessary in order to make them more rigid. The objective of this research was to produce and characterize pequi oil microparticles in a cashew gum (CG) and gelatin (GE) matrix cross-linked with tannic acid. Cross-linked pequi oil microparticles were produced by...

Microencapsulation and Storage Stability of Lycopene Extracted from Tomato Processing Waste BABT
Ranveer,Rahul C.; Gatade,Abhijeet A.; Kamble,Harshwardhan A.; Sahoo,Akshya K..
ABSTRACT The aim of this study was to optimize the encapsulation of lycopene using response surface methodology and to determine its stability. The lycopene was extracted from tomato processing industry waste. The extracted pigment was purified by crystallization method. The effect of different process parameters, viz, core to wall ratio, sucrose to gelatin and inlet temperature on encapsulation efficiency (EE) and encapsulation yield (EY) were studied. Structural study of encapsulated material was carried by using scanning electron microscope (SEM). The samples with and without encapsulation were stored under different conditions such as the presence and absence of air, sunlight, at room temperature and under refrigeration. Highest EE (92.6 ± 0.86) and EY...

Microencapsulation of grape seed oil by spray drying Ciênc. Tecnol. Aliment.
BÖGER,Bruna Raquel; GEORGETTI,Sandra Regina; KUROZAWA,Louise Emy.
Abstract In the search for alternative wall materials to replace gum Arabic (GA), a good but expensive encapsulating agent, this work aimed to evaluate the effectiveness of maltodextrin 10DE in combination with GA (GA/MD, 50:50 ratio) for the microencapsulation of grape seed oil by spray drying. The addition of maltodextrin to gum Arabic did not influence the mean particle diameter, powder bulk density, encapsulation efficiency or the total oil retained in the microspheres. Although the oil encapsulated with GA showed greater retention of phenolic compounds after spray drying, the sample encapsulated with GA/MD had greater ferric reduction antioxidant power and DPPH radical scavenging activity, and a lower peroxide index.

MICROENCAPSULATION OF TURMERIC OLEORESIN IN BINARY AND TERNARY BLENDS OF GUM ARABIC, MALTODEXTRIN AND MODIFIED STARCH Ciência e Agrotecnologia
Cano-Higuita,Diana Maria; Vélez,Harvey Alexander Villa; Telis,Vania Regina Nicoletti.
Spray-drying is a suitable method to obtain microencapsulated active substances in the powdered form, resulting in powders with improved protection against environmental factors as well as with higher solubility in water, as in the case of turmeric oleoresin. The present study investigated the spray-drying process of turmeric oleoresin microencapsulated with binary and ternary mixtures of different wall materials: gum Arabic, maltodextrin, and modified corn starch. A statistical simplex centroid experimental design was used considering the encapsulation efficiency, curcumin retention, process yield, water content, solubility, and particle morphology as the analyzed responses. Wall matrices containing higher proportions of modified starch and gum Arabic...
