Formulação de drageados de frutas com solução de reuso da desidratação osmótica de abacaxi

The objective of this work was to evaluate the reuse of sucrose syrup in pineapple (Ananas comosus) osmotic dehydration and the application of the spent solution in fruit dragée formulation. Osmotic dehydration trials were performed in five cycles (65° Brix/45°C/3 hours), directly reusing the osmotic solution, with only one intermediate reconditioning step. Variations in osmotic solution properties and in dehydration parameters were observed, as well as a low microbial load in the system. The spent solution was rich in vitamin C (30 mg 100 g-1). Pineapple dragée covered with red fruits and acai powders were obtained with the reconditioned spent solution used as an adhesion solution. The dragée presented high levels of vitamin C (176 mg 100 g-1), polyphenols (154 mg GAE 100-1 g), carotenoids (220 µg 100 g-1), and potassium (330 mg 100 g-1). The product showed good sensory acceptance and purchase intention. Reusing sucrose syrup is technically feasible during pineapple osmotic dehydration, as is the application of the spent solution as an ingredient in fruit dragée production.O objetivo deste trabalho foi avaliar o reuso do xarope de sacarose na desidratação osmótica de abacaxi (Ananas comosus) e o uso da solução final na formulação de drageados de frutas. Os ensaios de desidratação osmótica foram conduzidos em cinco ciclos (65 °Brix/45°C/3 horas), com reuso direto da solução osmótica, com apenas uma etapa intermediária de recondicionamento. Foram observadas variações nas propriedades da solução osmótica e nos parâmetros da desidratação, bem como baixa carga microbiana do sistema. A solução final apresentou-se rica em vitamina C (30 mg 100 g-1). Foram obtidos drageados de abacaxi cobertos com frutas vermelhas e açaí em pó com a solução final recondicionada como solução de aderência. O drageado apresentou níveis elevados de vitamina C (176 mg 100 g-1), polifenóis (154 mg GAE 100 g-1), carotenoides (220 µg 100 g-1) e potássio (330 mg100 g-1). O produto teve boa aceitação e intenção de compra. O reuso do xarope de sacarose é tecnicamente viável na desidratação osmótica de abacaxi, bem como a aplicação da solução final como ingrediente na produção de drageados de frutas

Chewy Candy As A Model System To Study The Influence Of Polyols And Fruit Pulp (acai) On Texture And Sensorial Properties

The growing demand for sugar-free confectionery products with fruit added motivated the study of a dietary model system (chewy candy) to be the basis for the incorporation of a tropical Brazilian fruit (acai - Euterpe oleracea Mart.) with outstanding sensorial properties. The effect of the polyols maltitol, isomalt, xylitol and erythritol was evaluated on the water activity and instrumental texture of the dietary model systems through a simplex lattice mixture design. The trial with the best performance was chosen to incorporate a spray-dried acai powder and was compared to a reference acai chewy candy containing sucrose by sensory analysis. The sucrose replacement by isomalt and erythritol resulted in a soft texture (hardness of 4.08 N), proper water activity (0.43) and stable dietary system concerning the maintenance of shape. The addition of spray-dried acai powder (10.4 g/100 g, in dry basis) at this system enabled to explore the flavor and color potential of the fruit and to eliminate the addition of vegetable fat generally used at the conventional formulation. The sensory tests indicated that the no-added sucrose acai chewy candy was acceptable for all the evaluated attributes and approved regarding purchase intent, presenting better results than the containing-sucrose acai chewy candy.

Co-crystallization of paprika oleoresin and storage stability study

Abstract Paprika oleoresin was co-crystallized to formulate a natural and hydrophilic dye for use in food applications. The color stabilities of the co-crystallized and free oleoresins were evaluated at different temperatures (25 and 35 °C, 70% RH) and light exposures (light 70 watts and dark, 25 °C, 70% RH). Co-crystallization from supersaturated sucrose syrup (S = 1.32) was found to be optimum for the formation of sugar agglomerates in a few minutes, with the paprika oleoresin entrapped inside. With time, decreases in the values of the a* parameter and the β-carotene content were observed with increasing temperature and with the incidence of light. The color degradation kinetics were dependent on both factors. The loss of color was greater for the free oleoresin as compared to the co-crystallized, suggesting that the co-crystallization process improves oleoresin retention in the sugar matrix, making it less susceptible to losses due to color degradation

Effect Of Differently Processed Acai (euterpe Oleracea Mart.) On The Retention Of Phenolics And Anthocyanins In Chewy Candies

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)This study investigated the effects of processing and storage on the physicochemical properties and retention of antioxidant compounds of no-added sucrose chewy candies (NASC) incorporated with differently processed acai (frozen pulp, spray-dried and freeze-dried powders). NASC containing freeze-dried acai had the highest softness and recoveries of total phenolic (TP) and total anthocyanin (TA) immediately after production. Colour parameters and antioxidant capacity by ABTS and ORAC assays had no significant differences after 6months of NASC storage, except for ORAC in NASC containing spray-dried acai, whereas DPPH center dot in all samples significantly increased. Water activity and hardness also increased after storage, whereas TP and TA contents decreased, despite presenting good retentions (approx. 72-78% TP and 84-99% TA). This study suggests that acai has a great potential to be used as a natural pigment and antioxidant source in candy manufacturing, meeting consumption trends towards healthier products.511226032612National Council for Scientific and Technological Development (CNPq)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Optimization of the production of double-shell microparticles containing fish oil

Fish oil incorporation into food products is a challenge because long-chain fatty acids are susceptible to oxidation. Microencapsulation is an alternative for protecting and delivering fish oil besides masking undesirable flavours. This work aimed to produce spray-chilled microparticles using spray-dried microparticles loaded with fish oil as the core material and evaluate the effects of core concentration and lipid wall material composition on the apparent viscosity of the feeding material (suspension), microparticle mean diameter (D50), moisture content and eicosapentaenoic acid and docosahexaenoic acid losses. Double-shell microparticles containing fish oil were successfully obtained. Higher core concentrations resulted in higher feeding material viscosities and microparticles with higher D50 values and higher moisture content, but suitable for food applications. Less eicosapentaenoic acid and docosahexaenoic acid loss was achieved with lipid matrixes containing palm fat/vegetable fat ratios of up to 40/60 or a ratio of 50/50 when associated with a low concentration of core material. The remaining eicosapentaenoic acid and docosahexaenoic acid content observed in the final double-shell microparticles and its good oxidative stability can be considered sufficient for the successful application of these microparticles in foods. These findings may contribute to expanding the use of microencapsulated fish oil255359369CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPNão tem2015/12398-4The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was financially supported by the Sa˜o Paulo Research Foundation (FAPESP) (Process 2015/12398-4) and by the National Council of Research and Technological Development (CNPq) that provided a scholarship to K.B.F.
