Abstract Environmental stress contributes to food insecurity, poverty, forced migration and violent conflict in the Sahel, with climate change aggravating the situation. The production of gum arabic from the acacia tree increasingly aligns with the community stakeholders’ efforts to promote climate change mitigation, adaptation and resilience. Based on expert interviews and field observations in Niger, and a reading of relevant documents, I found that gum arabic production is valuable for conflict mitigation because it helps tackle the root causes of violent conflicts. The acacia gum tree is a natural soil fixer and multinational companies have coveted the resin from the tree, which is a rising commodity and a promising source of revenue for the local inhabitants. As different communities work together and cooperate with outside actors (government agencies, international partners, NGOs and businesses), the opportunities to build social cohesion around the tree increase. By facilitating ecological improvement, social inclusion and poverty alleviation, the promotion of gum arabic production, despite other issues such as bad natural resource governance, is a critical environmental peacebuilding strategy. Hence, suitable funding of massive afforestation with the acacia tree fits with community-based natural climate solutions to global humanitarian issues by protecting and restoring the local environment.

Microencapsulation is a well-known technology for the lipid delivery system. It prevents the oxidation of fatty acids and maintains the quality of lipid after extraction from oil seed and processing. In flaxseed oil, the amount of ω-3 and ω-6 polyunsaturated fatty acids are 39.90–60.42% and 12.25–17.44%, respectively. A comprehensive review article on the microencapsulation of flaxseed oil has not been published yet. Realizing the great advantages of flaxseed oil, information about different technologies related to the microencapsulation of flaxseed oil and their characteristics are discussed in a comprehensive way, in this review article. To prepare the microcapsule of flaxseed oil, an emulsion of oil-water is performed along with a wall material (matrix), followed by drying with a spray-dryer or freeze-dryer. Different matrices, such as plant and animal-based proteins, maltodextrin, gum Arabic, and modified starch are used for the encapsulation of flaxseed oil. In some cases, emulsifiers, such as Tween 80 and soya lecithin are used to prepare flaxseed oil microcapsules. Physico-chemical and bio-chemical characteristics of flaxseed oil microcapsules depend on process parameters, ratio of oil and matrix, and characteristics of the matrix. As an example, the size of the microcapsule, prepared with spray-drying and freeze-drying ranges between 10–400 and 20–5000 μm, respectively. It may be considered that the comprehensive information on the encapsulation of flaxseed oil will boost the development of functional foods and biopharmaceuticals.

Разработаны рецептуры и технологии хлеба и хлебобулочных изделий из композитной смеси пшеничной муки высшего сорта и гречневой муки (1) и обойной муки из зерна пшеницы 5-го класса (2) с применением полисахаридов (ПС) в концентрациях, %: ксантана 0,5; трагаканта 0,6. В процессе исследования в опытные образцы хлеба вводили ПС: трагакант (Sugarflair Colours, Англия), ксантан (Deosen, Китай), гуар (Guarsar, Индия), гуммиарабик (Sugarcraft Essentials, Англия) в концентрациях от 0,5 до 1,5%. Установлено положительное влияние ксантана и трагаканта на качество хлеба. Влажность хлеба из композитной смеси (1) увеличилась на 0,54 и 1,64%; пористость – на 6,0 и 1,4% соответственно. Влажность хлеба (2) увеличилась на 0,6 и 5,1% соответственно, пористость – в среднем в 1,7 раза. Разработанные образцы хлеба с добавлением ПС рекомендованы для рациона как источник основных нутриентов. По микробиологическим показателям опытные образцы соответствуют требованиям ТР ТС 021/2011. Калорийность образцов из муки (2) и композитной смеси (1) составила 178,84 и 198,00 ккал соответственно, что необходимо учитывать в диетическом и функциональном питании. Разработанные рецептуры и технологии хлебобулочных изделий с добавлением ПС перспективны для применения на предприятиях хлебопекарной промышленности и индустрии питания. The opportunity of using polysaccharides (PS) in the recipes and production technology of bakery products from a composite mixture of high-grade wheat flour and buckwheat flour (1) and wholemeal flour from fifth-grade wheat (2) with concentrations of xanthan 0,5% and tragacanth 0,6% was studied. Polysaccharides of various origins were introduced into the experimental samples, namely: tragacanth (Sugarflair Colors, England), xanthan (Deosen, China), guar (Guarsar, India), and gum arabic (Sugarcraft Essentials, England) in concentrations from 0,5 to 1,5%. The positive influence of xanthan and tragacanth on the quality of bread was established. Humidity of bread from the composite mixture (1) increased by 0,54 and 1,64%; porosity – 6,0 and 1,4%, respectively. Humidity bread (2) increased by 0,6 and 5,1%, respectively, porosity – an average of 1,7 times. Designed bread samples with the addition of PS are recommended for the diet as a source of essential nutrients. According to microbiological parameters, the prototypes satisfy the requirements of TR CU 021/2011. The caloric value of the samples from flour (2) and composite mixture (1) was of 198,00 and 178,84 kcal, respectively, what needs to be considered to consider dietary and functional nutrition. The data obtained allow us to recommend our developed technological solutions to bakery enterprises.

This study investigated the effect of gum Arabic and starch-based coating and two polyliners (Liner 1-micro-perforated Xtend® and Liner 2-macro-perforated high-density polyethylene) on whole ‘Wonderful’ pomegranate fruit during cold storage (5 ± 1 °C and 95 ± 2% RH). Uncoated (UC) and coated (GAMS) fruit were packaged into standard open top ventilated cartons (dimensions: 0.40 m long, 0.30 m wide and 0.12 m high) with (GAMS + Liner 1, GAMS + Liner 2, UC + Liner 1 and UC + Liner 2) or without (UC and GAMS) polyliners. After 42 d, treatment GAMS + Liner 1 recorded the least weight loss (4.82%), whilst GAMS recorded lower (8.77%) weight loss than UC + Liner 2 (10.07%). The highest (24.74 mLCO2 kg−1h−1) and lowest (13.14 mLCO2 kg−1h−1) respiration rates were detected in UC and GAMS + Liner 1, respectively. The highest and lowest total soluble solids were recorded for GAMS (16.87 °Brix), and GAMS + Liner 1 (15.60 °Brix) and UC + Liner 1 (15.60 °Brix), respectively. Overall, no decay was detected for coated fruit packaged with either Liner 1 or Liner 2. Therefore, the combination of GAMS with Xtend® polyliners proved to be an effective treatment to maintain the quality of ‘Wonderful’ pomegranates during storage.

The effect of six edible coatings were investigated on the ability to alleviate shrivel and extend shelf life of plums. Fruit were subjected to a simulated shipping period (−0.5 ± 2 °C and 90 ± 5% relative humidity (RH)) for five weeks and a subsequent shelf life period (20 ± 2 °C and 80 ± 5% RH) for 20 d. Overall, the study showed that it is possible to alleviate shrivel and also extend shelf life of plum (‘African Delight™’) at export and shelf life conditions. Amongst the edible coatings investigated, the findings in fruit coated with gum arabic and the commercial products were comparable and promising for postharvest preservation of the investigated plum cultivar. The coatings showed a moderate delay of fruit ripening, significantly reduced weight loss and shrivel development, allowing for the export of fruit over a long distance (five weeks) and up to 20 d of shelf life.
