Eating edible insects in Republic Democratic of Congo is a tradition for centuries but a lack of knowledge remains about an actualized inventory of species consumed in the country. Moreover, a rigorous taxonomic matching of the used vernacular name of edible insects and a precise characterization of the sector of entomophagy are still needed. According to our studies focused on the city of Kinshasa, 14 edible species were inventoried as regularly consumed. They belong respectively and by degree of importance to the Lepidoptera (46.7%), Isoptera (18.6%), Orthoptera (17.6%), Coleoptera (9.7%) and Hymenoptera (3.7%) orders. Generally 80.0% of the Kinshasa population consumes at least one species of insects 5 days per month. The key peoples in the edible insect sector are mostly women. The incomes generated by this activity contribute to the well being of households, to reduce poverty and food insecurity in the capital Kinshasa. Future studies should focus on sustainable ways of harvesting wild populations, the use of improved conservation practices, the enhancement of cottage industries for farming insects and the development of economically feasible ways of mass-rearing edible species.

Meat plays an important role in the consumption pattern of most European and North American consumers. Meat production is responsible for a well known environmental pressure due to the inefficient conversion of plant protein to meat protein and alternatives sources, such as insects or algae, will be rapidly required. In a recent theorical study, de Boer et al. (2013) show that consumers prefer to eat a hybrid meat product (i.e. a mix of meat and its substitute) rather than a pure meat substitute [3]. Based on these preliminary results, hedonic tests were realized to assess the acceptability of insect-based burgers in a target population composed of people from 15 to 25 years old, considered as the future insect consumers. Isolated in a tasting booth, each participant was invited to taste four burger samples containing a ratio of 20 gr of protein by 100 gr of burger. The first burger was prepared with 95% of grounded beef (1), the second with 95% of green lentil (2), the third with 45% of green lentil and 50% of mealworms (Tenebrio molitor L.; Coleoptera, Tenebrionidae) and the fourth with 45% of grounded beef burger and 50% of mealworms. The last 5% of each burger consists of an aromatization portion containing onions, carrots, tomato paste and garlic. Participants were asked to rate each sample on a 9-point hedonic scale, where extreme sides were noted from “extremely dislike” (left) to “extremely like” (right). Tukey post-hoc comparisons on the appreciation results showed that beef-based products (with or without mealworms) were relatively preferred to lentil-based products (with or without mealworms), probably because hybrid meat burgers seem more familiar to the consumers than vegetable burgers, and that no liking differences were noticed between the two beef-based burgers and between the two insect-based burgers. These results confirm that shape and appearance are key criteria in the acceptation of meat substitute by non-vegetarian consumers and that insects will preferentially be consumed, in the future, if they are presented in an invisible way and associated with familiar flavors.

Different particle size sunflower tahini prototypes were obtained by controlling the milling process of roasted sunflower kernels. Not only the physicochemical properties of these samples but also of an industrial reference were compared and discussed in order to understand tahini behavior and structure. Granulometry was determined by a laser-scattering analyzer and revealed for all studied samples, trimodal particle size distributions. Histogram modes, as well as cumulative volume percentages (CVPs) of smal l- and middle-class populations, increased with the number of passes through colloidal mill, while for large particle size population, both the modes and CVPs decreased. Pseudoplastic behavior was observed for all sunflower tahini prototypes and reference, irrespective of studied temperature and particle size. However, the value of consistency coefficient ranged from 3,049 to 6.6 Pa·s n being strong dependent on particle size and temperature while flow behavior indexes between 0.53 and 0.87. Time-dependent rheological analysis revealed higher thixotropic degree of coarser sunflower tahini samples. Studied samples had rheological properties characteristic for a viscoelastic mate- rial, the response in the dynamic frequency sweep being typical for weak gels. The finest sunflower tahini prototype showed the lowest Krieger–Dougherty estimated volume fraction (0.48), while the coarsest sample the highest (0.69), sunflower tahini reference being placed in a median position with a volume fraction of 0.56. By combining all those data, a schematic structure of sunflower tahini was pro- posed for the first time [less ▲]

Objectives: To determine the physicochemical properties of the oil obtained from Tenebrio molitor Larvae and explore its potential as edible oil. Methodology: Oils obtained from five batches of Tenebrio molitor Larvae were investigated. Among the samples, three were produced directly in the lab (3 different productions) and 2 were purchased from a local supplier. In addition to the total lipid content (solvent extraction), both FA (GC) and TAG (HPLC) profiles were determined. Thermal properties by DSC were also estimated. Results and conclusion: The fresh Larvae from the lab contained 52% of total proteins (% dry matter). Their total fat content was around 36% (% dry matter). The commercial samples contained more proteins, but less fat: around 58% of total proteins and 30% of total fat (% dry matter). All the extracted oils contained high amount of unsaturated fatty acids. However, the chemical composition and the thermal properties of the samples varied according to their origin. The level and quality of lipid content offer potential as a substitute of oilseeds. [less ▲]

Rising economies and rapid urbanization in developing countries, particularly in Asia, are creating shifts in the composition of global food demand, so it is necessary to explore new sources of food with better nutritional profile. Among the alternative food that exists are the grasshoppers, about 80 species of which are consumed worldwide. Grasshoppers are not only rich source of proteins and lipids but also some important minor component like vitamins and minerals. Apart from being nutritionally superior to most conventional meats their production results in lower emission of greenhouse gases & ammonia, risk of zoonotic infections in humans is much lower, water requirement for production is much less and have higher feed conversion ratio. Edible species of grasshopper in Belgium were identified, attempts were made for the lab rearing of meadow grasshopper (Chorthippus parallelus) and fat as well as protein contents of meadow grasshopper (Chorthippus parallelus) & long winged conehead (Conocephalus discolor) were investigated.

Dextrins are partially hydrolyzed starch products which are used in a wide range of applications. Hydrolysis can be performed by acid or enzymatic reaction. However the properties of dextrins are influenced by the type of reaction and the source of starch. The aim of the present study was to determine physicochemical properties of dextrins obtained from hydrolysis of starches (corn and wheat) and flours (wheat and cassava) by using sorghum malt amylases. Hydrolysis of starches and flours was performed at 65°C, the hydrolysates were centrifuged and spray-dried for analysis. Physicochemical and structure of the powders were investigated. Results showed that the proportion of DP2 (maltose and isomaltose) was higher in dextrins and more in dextrins from wheat flour. Low water activity and low dissolution time were found in all dextrins. XRD patterns revealed that the crystalline structure partially disappeared in some of them. At 30% concentration, we noted a Newtonian behavior for the dextrins. The freeze-concentrated T0 g and the peak melting temperature (T0 m) determined by DSC (DSC) showed lowest values for dextrins from wheat. Thermogravimetric analysis (TGA) revealed that the dextrins were quite stable until 200°C. [less ▲]

Sunflower “halva” is a popular and widely enjoyed confectionery product specific to the countries of Eastern Europe. Conventional halva has historically been produced from sesame seeds in the Middle East and Northern Africa. However, in the production of halva in Eastern Europe, sesame seeds have been largely replaced by sunflower seeds, due to the high availability of sunflower in this region and the comparable taste of the final product. Due to the importance of the cost of raw materials in the food industry, utilization of sunflower seeds in halva production may be of great interest worldwide because it offers the possibility of significantly lowering production costs. Nevertheless, oil separation and storage techniques must be perfected if sunflower halva is to fulfill its promise of becoming a cost effective alternative to sesame seed halva on a worldwide scale. The aims of this review are firstly, to describe the current state of sunflower halva technology, secondly, to isolate the main problems affecting the quality of the final product, and hirdly, to suggest areas of further research necessary to move sunflower halva production closer to reaching its full potential on the world market.

Total proteose-peptone (TPP) fractions were extracted from skimmed milk (UHT) and whey protein concentrate (WPC) on a laboratory scale. Protein solutions (0.1 %, 0.5 %, and 1 % w/w) were characterized as function of pH: 4.0, 4.6–4.7 (native pH), and 7.0. Their foaming capacities and stabilities were studied. Beforehand, the surface properties that govern them were investigated, notably the kinetics of adsorption and mechanical properties of monolayer films at the air–water interface involved in the formation and the stability of foams respectively. The TPP extracted from skimmed milk showed the lowest values as well as a significant reduction in surface tension and presented a good mechanically resistant film. The TPP extracted from WPC presented a better foaming capacity and stability which was unexpected. However, foaming properties and surface properties of TPP fractions depended on the pH. The considerable influence of extraction source and method on proteosepeptone’s properties were highlighted. [less ▲]
