Quality Characteristics of Fruit Jams and Marmalades Containing Gum Arabic Fromacacia Senegal Var. Kerensis

Jams and marmalades are some of the most popular fruit products because of their low cost, all year long availability and appealing sensory properties. These products are described as gels with pectin as the gelling agent used in its formulation. Gels are a form of matter intermediate between a solid and liquid consisting of polymeric molecules cross-linked to form tangles. Under mechanical stress, pectin gels may be damaged leading to the release of colloidal water termed as syneresis. This ...

Optimization of brewing, processing conditions and their effects on the chemical and sensory quality of purple-leafed Kenyan tea

The Tea Research Institute (TRI) developed TRFK 306 tea clone which is rich in anthocyanin as a strategy to diversify Kenyan teas. TRFK 6/8 was used as a control in the study being a standard clone used at the TRI. TRFK 306 can be utilized non-processed but there is no well researched, documented data on the best brewing conditions. Consumers add edible acids to its brew to improve the colour and taste but information on the acid effect is scanty. Information on the quality of products manufa...

Effects of Drying on the Nutritional, Sensory and Microbiological Quality of Edible Stinkbug (encosternum delgorguei)

Abstract/Overview Entomophagy has recently gained attention as a potential solution to the problems of food and nutritional security. One example is the consumption of edible stinkbug. Different drying techniques may affect the nutritional, microbiological and sensory properties of the edible stinkbugs. Thus, the study assessed the effects of toasting, microwave, oven and sun drying on the nutritional composition, microbiological quality and sensory attributes of processed edible stinkbug...

Variability in Nutrient Composition of the Edible Long- Hornedgrasshopper (Ruspolia Differens) in Uganda and its Potential in Alleviating Food Insecurity

Abstract/Overview Ruspolia differens Serville (Orthoptera: Tettigonidae) is a highly nutritious and luxurious insect delicacy that is consumed as a food source in many African countries. However, the nutrient profile of R. differens in different geographical regions have received limited research interest. Here, we provide comprehensive evidence of geographical impact on the nutrient profile of R. differens and its potential to meet the recommended dietary intake of the population. Our re...

Consumer Religiosity and Its Influence on Their Uptake and Consumption of Edible Insects among Selected Communities in Western Kenya

Abstract/Overview Global food demand is expected to rise due to the population increase estimated to reach 9.5 billion by the year 2050. As a result, the available natural resources such as water sources and land will become scarce and overused. Indisputably, other sustainable food resources need to be identified and practised to solve the problem of food inadequacy. The world population will be encouraged to eat less consumed food resources. Edible insects have been identified as sustain...

A Comparative Evaluation of Nutrient Content of Fall Armyworm (Spodoptera Frugiperda) Larvae to Other Chicken Feeds

Abstract/Overview Fall armyworm (FAW) Spodoptera frugiperda is a devastating pest of over 350 plant species especially the cereal crops such as, maize, sorghum and rice. The pest is currently posing threats to food security in Africa. FAW could be potential animal feed that can supplement chicken feed. However, there is little information on its nutritional profile as poultry feed. The aim of the study was to compare the nutrient content of FAW larvae to other chicken feeds. Proximate ana...

Utility of anticipatory management approach in regulating motorcycle public transport in Kisii town, Kenya

Abstract/Overview The use of Motorcycles Public Transport (MPT) is partly the cause of heavy traffic congestion in Kenya’s urban centers. Sustainable urban transport implies systematic change in approaches to urban transport service provision, regulation and efficiency improvement. This study was conducted in Kisii town, Western Kenya, a medium-sized town characteristic of high Motorcycle-related Traffic Congestion (MTC). Several scenarios in Kisii town have promoted and sustained use o...

Effects of housing on growth performance of common house cricket (Acheta domesticus) and field cricket (Gryllus bimaculatus)

Abstract/Overview Cricket rearing is emerging as an important component of animal food. However, suitable housing for medium and large - scale production still presents a major challenge. This study sought to investigate the effect of housing on growth performance of two cricket species: Acheta domesticus and Gryllus bimaculatus. Both species were reared in the two housing systems used in the experiment; the tunnel unit and the prefabricated house. The crickets were fed on growers’ mash...

Growth performance of common house cricket (Acheta domesticus) and field cricket (Gryllus bimaculatus) crickets fed on agro-byproducts

Abstract/Overview Abstract The present study was conducted to investigate the growth performance of Acheta domesticus and Gryllus bimaculatus fed on different agro-byproducts. The experiment was carried out between February- July 2017 within Jaramogi Oginga Odinga University of Science and Technology Insect Farm. Randomized Complete Block Design was used as the experimental design with four treatments: rice bran+ blood meal (RBBM), rice bran + spent grain (RBSG), & + rice bran + spent yea...

Acceptability of Cereal-Cricket Composite Porridge as Influenced by Socio-Economic Factors and Breast-Feeding Status of Mothers and Care-Givers in Siaya County, Kenya

Abstract The trajectory for widespread integration of edible insects into the human diet is still confronted by low acceptability especially among communities that traditionally or habitually do not consume insects. While the concern today is how best to present edible insects into food matrices that improve their acceptability, this development should be aligned with consumer intrigues into the choices of insect-based foods. This study determined the influence of socio-economic factors (age...

Lipid Stability in Soy Flours Produced From Raw and Processed Soybeans

ABSTRACT Soybean, a high protein/oil legume is known to contain high levels of polyunsaturated fatty acids, which are susceptible to lipid oxidation and hydrolysis. However, suitable processing methods and storage conditions can enhance the stability of lipids in soy flour. The objective of the project was to investigate the effects of some processing methods and storage conditions on the stability of lipids in soy flour and to define the parameters for the prediction of the shelf life of soy...

MICROBIOLOGICAL QUALITY AND SAFETY OF FRUIT JUICE SERVED IN CAFES OF DIRE DAWA TOWN, EASTERN ETHIOPIA

Abstract: Fresh fruits are essential components of the human diet and there is considerable evidence of the health and nutritional benefits associated with the consumption of fresh fruits. However, during processing contamination from raw materials, equipment or food handlers could be easily transferred to the final product of fruit juices resulting food-borne illnesses. Therefore, the aim of this research was to evaluate the microbiological safety of avocado, mango and papaya fruit juices a...

THE ROLE OF ACETYLSALICYLIC ACID IN DELAYING POSTHARVEST RIPENING OF APPLE (Malus domestica Borkh.)FRUIT

Abstract: Apples are the natural source of dietary mineral salts, vitamins, antioxidants, fiber, organic acids and sugars. Reduction of post-harvest losses and quality deterioration are essential in increasing food availability from the existing production. Minimizing this loss has a great significance for food security, economic growth and welfare of the society. This study was planned to investigate the role of asprin (acetylsalicylic acid) treatment in improving post harvest quality, shel...

THE EFFECT OF Aloe vera Mill. GEL COATING ON POSTHARVEST QUALITY OF AVOCADO (Persea americana MILL.) FRUITS

Abstract: Aloe vera gel has been proven to be one of the best edible and biologically safe preservative coatings for different types of foods because of its film-forming properties, antimicrobial actions, biodegradability and biochemical properties. This study was planned to investigate the role of aloe gel coating in improving post harvest quality, shelf life, sugar and antioxidant (carotenoid) content of avocado fruit. The experiment was laid in completely randomized design (CRD) in two re...
