Encapsulation of Bilberry Extract with Maltodextrin and Gum Arabic by Freeze-Drying: Formulation, Characterisation, and Storage Stability

Abstract: Anthocyanins are polyphenolic plant pigments associated with antioxidant and health-promoting properties. However, their application in the food industry is limited due to their poor stability. The purpose of this study was to encapsulate anthocyanin-rich bilberry (Vaccinium myrtillus L.) extract by freeze-drying and to investigate the effects of different wall materials and extract contents on the physicochemical and bioactive properties of the obtained encapsulates. Ethanolic bilberry extract was encapsulated with the use of maltodextrin (16.5–19.5 DE) (MD), gum Arabic (GA), and their combination in a 1:1 w/w ratio (MIX). Bilberry solids to wall material ratios were examined at 20:80, 30:70, and 40:60. All encapsulates showed an attractive red colour and low water activity values (aw ≤ 0.3) that indicated a low risk of microbial spoilage. In general, the biggest losses of total phenolic compounds and anthocyanins during three-week storage in the dark and at room temperature (20 ± 2 °C) were detected in the case of encapsulates with a higher content of bilberry extract (MIX30 and MIX40, and GA30 and GA40, respectively). The use of maltodextrin provided the best protection to bilberry anthocyanins during forced storage. Overall, the obtained encapsulates show suitable potential for the development of food products with added nutritional benefits.

Co-integration relationships among major gum arabic markets in Kano State, Nigeria

Abstract: The study examined price co-movements of various grades of gum arabic in the major gum arabic markets in Kano State. Purposive sampling technique was employed to select five major markets in five local government areas and price time series data were collected weekly for fifty-two weeks from the various markets under study. The price information of the different grades of gum arabic were decomposed and subsequently subjected to cointegration procedure. The results revealed various levels and directions of price co-movements among the markets. The study concludes that gum arabic prices varied and co-moved between market pairs at different periods of the year. The study recommended that since most of the markets were co-integrated, establishment of a central market in the study area will further improve better pricing mechanism, collective bargaining and control. Buffer stock storage facilities could be provided by cooperative association in collaboration with the government and private sector.
