Due to high cost of importation and inability of wheat to thrive in Nigeria, baked products like chin-chin are costly and out of the reach of common people. Since baked products are convenient snack relished by all, substitution with readily available materials like cassava flour becomes the only available option. Wheat and cassava flours were blended in the ratios of 70:30%, 50: 50% and 30: 70% respectively while 100% wheat and cassava flours served as controls. Deep fat fried chin-chin samples were prepared from the blends. Proximate and functional properties were conducted on the flour blends while proximate composition and acceptability test were on the chin-chin samples. The results revealed that with increase in cassava inclusion levels in the composite flour blends, there was increase in moisture (7.77-8.23%), carbohydrate (73.42-79.23%), ash (0.75-1.00%), bulk density (0.51-0.61 g/ml), swelling index (0.96.1.09%), water absorption capacity (1.10-1.88 g/g), and emulsion capacity (27.41-39.48%) while dry matter (91.20-9.84%), protein (8.55-6.55%), fat (2.08-0.98%), fibre (2.53-2.20%) and oil absorption capacity (1.29-1.16 g/g) decreased. For chin- chin, there was significant increase in moisture (8.29-10.40%) and carbohydrate (63.63-66.54%) while dry matter (91.70-89.59%), protein (6.66-3.50 %), fat (17.57-16.84%), ash (1.88-1.38) and fiber (1.96-1.69%) decreased. There was no significant difference in the overall acceptability of the chin-chin samples. Therefore, cassava flour substitution of up to 70% is acceptable, but with decrease in most of the nutrient composition which can be improved with lower (

This study was designed to investigate the therapeutic effects of Vitis vinifera L. seed extract (5 ppm and 10 ppm) on gill and liver tissues histopathology of carp (Cyprinus carpio L. 1758) exposed to cadmium chloride (CdCl2=Cd) (20 ppb) acute and subchronic period. A total of 140 fish in 14 groups were used in the experiment. The experiment was designed as in two different periods (acute and chronic) and 7 different dose groups (control, vehicle, V. vinifera seed extract 5 ppm, V. vinifera seed extract 10 ppm, Cd 20 ppb, V. vinifera seed extract 5ppm + Cd 20 ppb and V. vinifera seed extract 10 ppm + Cd 20 ppb). At the end of the experiment, the gill and liver tissues dissected from the fish were fixed, dehydrated, cleared, and paraffin impregnated. Appropriately sized blocks were prepared from the tissues, sections of 5-7 µm thickness were taken and covered by staining with hematoxylin-eosin. Stained preparations were examined under a light microscope and photographed. It was determined that all dose groups in the acute period and control groups were not different histopathological. It was determined that the histopathological damage caused by the cadmium group in the subchronic period and tissue damage were reduced in the dose groups with cadmium added with V. vinifera seed extract. As a result of the study, it was concluded that V. vinifera seed extract could have a therapeutic effect on the gill and liver tissues of carp exposed to cadmium.

Oxidative stress resulted from free radicals and reactive oxygen species (ROS) are associated with many diseases. Phytotherapy has known a great evolution all the world and some medicinal plants are important remedies of some diseases. Myrtle (Mrytus communis L.) is a plant of Myrtaceae family which is common in the Mediterranean region, with flowering, always green leaves and fruit. This study aims to investigate in vitro antioxidant capacity of Myrtus communis berries methanol extract and its three fractions using five assays: ABTS scavenging radicals, metal chelating, hydrogen peroxide and inhibition of lipid peroxidation assays. EAE extract possessed the highest antioxidant activity in ABTS (EAE (IC50=2.5 µg/ml ) and lipid peroxidation models (90.17%). Whereas, AqE is the most active extract in metal chelating activity (IC50=0.73±0.03 mg/ml) and H2O2 assay. These results support the traditional use of this plant in healthcare and it could be a new source of antioxidant natural drugs.

Processing tomato is an important agricultural crop worldwide suffering from genetic erosion due to a severe genetic diversity reduction and domestication hindrance. In Tunisia, some old underutilized tomato cultivars are increasingly being considered as genetic resources and are marginally used by small farmers constituting a real safety valve for the sustainability of the processing tomato value chain. Those tomato cultivars differ in their biometric, processing and functional quality attributes. Therefore, there is an increasing interest to examine their performances for processing and fresh market quality improvement. Recently, there was also a particular focus on improving the quality of fresh fruit via the introgression of high-pigment genes in processing tomato in order to obtain a high quality processed products. The results are important as large differences are highlighted and the main traits affecting tomato quality are also reported and clearly discussed. This suggest that maintaining of the existing genetic pools among cultivated tomato is as important as creating novel hybrids.

This study was carried out in order to determine the effects of dill, clove and hyssop essential oils and fungicides applied on sugar beet roots on beet storage quality during the storage period. The roots of Esperanza (KWS) variety, which was produced in the experimental areas in 2019, were used in the study. Roots were treated with 100, 500 and 1000 ppm doses of dill (Anethum graveolens L.), clove (Szygium aromaticum) and hyssop (Echinophora tenuifolia) essential oils, synthetic fungicide (80% Thiram) and Tween-80 right after harvest and the roots were placed in the storage. Weight loss of roots determined at 15-day intervals from the beginning of the storage period, dry matter ratio, brix, polar sugar, reducing sugar and alpha amino nitrogen contents, phytotoxicity and fungal infection development at the end of the 3-month storage period. The applications made in the research significantly affected the post-harvest weight and quality losses in beet. Depending on the applications, the weight losses at the end of the 3-month storage period varied between 9.43-19.90%, and the weight losses in essential oil applications were lower than the control. The highest dry matter content and brix values were obtained from clove essential oil and fungicide and Tween-80 applications. While Tween-80 and fungicide applications increased the polar sugar content compared to the control, 1000 ppm clove essential oil caused a significant decrease in the polar sugar content. In the study, reducing sugar and alpha amino nitrogen contents of roots applied 1000 ppm essential oil E. tenuifolia essential oil were lower. E. tenuifolia essential oil showed the highest antifungal activity against white mold and green mold infections. It was concluded that with the application of essential oil to the roots after the harvest, both weight and quality losses and the development of fungal diseases can be reduced, however, some active substances may cause phytotoxicity in the roots.

The identification of plants in which the bees forage is key in establishing bee farms and increasing honey production. In this study pollen analysis of honey samples from the southeastern part of Nigeria was carried out to ascertain their floral sources and ecological origin. The honey samples were acetolyzed and microscopically studied to determine the pollen types. A total of seventy-one pollen types belonging to forty-one families of plants were identified. The honey samples were dominated by pollen grains from the families of Arecaceae, Euphorbiaceae, Myrtaceae, Irvigiaceae, Fabaceae, Combretaceae/Melastomataceae, and phyllanthaceae. Some of the dominant pollen grain identified include Elaeis guineensis, Alchornea cordifolia, Hymenocardia acida, Ocimum gratissimum, Syzygium guineense, Nauclea latifolia and Afzelia africana. Out of the six samples studied Njikoka sample was monofloral having Mimosa pigra as predominant pollen while Ayamelum, Ekwusigo, Nsukka, Ezeagu, and Udenu samples are multifloral containing Elaeis guineensis, Phyllanthus sp., Piliostigma reticulatum, Irvingia sp., Alchornea cordifolia, and Lannea sp. as major secondary pollen. All the samples analyzed have Elaeis guineensis in common except Ezeagu, indicating that these plants are present in all five locations. These results can also be used as a tool in the geographical identification of Southeastern Nigeria honey from other geopolitical zones.
