AB  - In this study principal component analysis and artificial neural networks were used to evaluate the potential of using binary mixtures of sodium alginate and other polysaccharide biopolymers as the carriers for microencapsulation of green tea bioactive compounds. Using binary mixtures of alginate and adjunct biopolymers increased the particle size (from 722 to 1344 mu m) and textural parameters of the microbeads. Chemometric techniques revealed the combination of biopolymers and their ratio as the main factors influencing the encapsulation performance. The combination of alginate with hydroxypropyl methylcellulose and locust bean gum enabled to retain the highest (-)-epigallocatechin gallate and caffeine contents, the highest total phenols encapsulation efficiency, and their most retarded release in water, confirming these as the best delivery systems of polyphenol-type active compounds and signifying their potent food applications.

AB  - The food industry expects increasingly complex properties (such as delayed release, stability, thermal protection, and suitable sensorial profile) from food ingredients, which often would not be able to be achieved without microencapsulation. This paper presents the state of the art in encapsulation technology for delivery of bioactive compounds to food. It reviews common encapsulation technologies (emphasizing their advantages and limitations) versus novel, interesting approaches in emerging technologies. This review includes a presentation of benefits resulting from the use of microencapsulated ingredients in the food industry; these benefits are going to be illustrated via few case studies bringing innovative processing. Spray drying has been used for more than 60 years to protect flavor oils against degradation/oxidation/evaporation, but melt dispersion technique has been used lately to effectively stabilize an aroma compound. Microgels produced by extrusion and emulsification techniques are considered for delivering synergistic antioxidant effects of plant extract polyphenols, their off-taste masking, and improved handling. Apart from microgels, microemulsions (produced by microfluidization or micelle formation techniques) are taken into account for entrapment of extracts containing polyphenols and essential oils. Innovative and interesting coacervation processes are depicted here as they facilitate the commercialization of coacervated food ingredients. Liposomes are gaining increasing attention in the food sector as they can provide good stability even in a water surrounding and also targeted delivery. The new scalable manufacturing protocols for the production of liposomes evolved in recent years (e.g., proliposome method) are presented here. Fluidized bed technology has been offering a versatile possibility to produce encapsulates which should release ingredients at the right place and the right time. Complex systems such as lipids in hydrogels are newly developed structures for controlled release of bioactive compounds. Finally, the effect encapsulates have when incorporated into real food products will be discussed, in particular with regard to the production of innovative functional food products. As an example, textural, sensorial, and physical quality assessment of chocolates enriched with encapsulated polyphenolic antioxidants from yarrow (Achillea millefolium L.) will be reviewed.

AB  - In this study a bottom-up approach of designing functional ingredients from green tea extract is proposed by a systematic investigation of 12 different natural biopolymers and their efficiency as carrier materials of green tea bioactive compounds by spray drying at low temperature (130 A degrees C). Screening of carriers revealed that inulin and whey proteins provide the highest product yields (67.04 and 65.18 %, respectively) and, accompanied with pectin, also the highest total polyphenols (67.5-82.2 %) and flavan-3-ols (93.7-75.9 %) loading capacity. Up to 162 mg/g of (-)-epigallocatechin gallate (EGCG) was achieved, while low-caffeine contents ( lt  5 mg/g) indicated the potential of obtaining low-caffeine functional ingredients. Employing alginate, carageenan and gums (acacia gum and xanthan) enabled the best colour preservation and highest chlorophyll content. Reconstituted green tea microencapsulates comprising modified starch, inulin or carageenan exhibited the lowest bitterness and astringency and the highest green tea flavour intensity as the most favourable sensory properties. An artificial neural network (ANN) designed based on the experimentally obtained results revealed hydrocolloid gums as the best encapsulants for achieving good physical properties, high EGCG contents and prolonged dissolution/release profiles while pectin, inulin and modified starch as the optimal ones in terms of the product yields, loading capacities and sensory properties. This indicates that a formulation comprising a combination of all of those biopolymers would provide potentially functional ingredients with encapsulated green tea phytochemicals, retained colour and improved sensory properties.

AB  - In this study, potential interactions of alginate-proteins and proteins-polyphenols were utilized for the formulation of microparticles encapsulating green tea flavan-3-ols and caffeine. Electrostatic assisted extrusion of alginate-protein (whey proteins, bovine serum albumine, calcium caseinate, soy proteins, hemp proteins) formulations was performed for the production of microparticles and the effect of chitosan or pectin coating was evaluated. Employing alginate in combination with soy or hemp proteins provided large and hard particles, while reinforcement with whey proteins and bovine serum albumin provided the most spherical and softer particles (lower hardness and elasticity), with average diameters around 700-800 mu m. The combination of alginate and calcium caseinate or whey proteins enabled to retain the highest content of polyphenols and caffeine in the formulated particles (up to 80%). Chitosan or pectin coating did not improve the physical and morphological properties or the encapsulation efficiency, but conferred better (prolongued) release profile of polyphenols from the particles. The release studies in water and simulated gastric and intestinal fluids revealed burst release of polyphenols (over 50% in first 5-10 min) followed by sustained release up to 120 min. An artificial neural network designed based on all physical and bioactive parameters of the formulated particles, revealed that the combination of alginate with calcium caseinate or bovine serum albumin as the delivery formulation and pectin coating would provide particles with the maximum loading efficiency of green tea polyphenols and proteins as the functional components, which may facilitate their functional properties when delivered to specific target media in the organism.

AB  - Resveratrol-loaded alginate submicron particles were prepared by emulsification followed by external gelation. Scanning electron microscopy analysis of the air-dried and freeze-dried submicron particles demonstrated their spherical shape, from 100 nm to 600 nm in size. The encapsulation efficiency and loading for resveratrol were 24.5% (+/- 1.6%) and 0.3% (+/- 0.05%), respectively. The interactions between the encapsulated resveratrol and alginate were characterised by Fourier transform infrared spectroscopy and differential scanning calorimetry. The release from the alginate submicron particles was successfully described by the linear superimposition model, which allowed concluding that resveratrol transport is governed by Fick's diffusion. The alginate submicron particles were prepared from materials that are considered as generally recognized as safe, and thus have good potential for use as a resveratrol delivery system in food products.
