Characterization and Evaluation of Physicochemical and Sensory Acceptability of Ice Creams Incorporated With Processed Ginger (Published)
The study was undertaken to develop different forms of the ginger ice cream using 5% ginger juice, 5% ginger paste and 5% ginger syrup. These ice cream samples were analyzed for physicochemical, microbial and sensory properties during 28 days of frozen storage at -20 0C. Incorporation of the juice, syrup and paste in ice cream reduced total solids, fat, acidity and total soluble solid, and increased antioxidant activity. Ash content increased with the ginger paste, whereas it decreased with the ginger juice and syrup. First dripping time amplified and melting rate declined with all the ginger preparations. And also textural properties increased and microbial activity decreased with ginger added ice creams. During storage, the total solid, ash, fat, total soluble solid content, dripping time and textural properties were significantly (p<0.05) increased. pH content, antioxidant activity and melting rate were significantly (p<0.05) decreased with the storage period. Organoleptic properties were evaluated though the panel of 30 members. As a results of organoleptic characteristics revealed that, 5% of ginger syrup incorporated ice cream had the highest mean score of overall quality of all sensorial properties namely, colour, taste and overall acceptability
DISINTEGRATION OF THE ISLET CELLS (OF LANGERHANS) FOLLOWING THE ADMINISTRATION OF ETHANOLIC EXTRACTS OF GINGER IN ADULT WISTAR RATS (Published)
This study elucidates the effect of ethanolic extract of ginger on the histology of the pancreas. Forty adult wistar rats weighing 190-200g were divided into five groups designated A, B, C, D, and E; each group containing eight experimental animals. The animals in groups A and B served as the control receiving distil water and olive oil respectively. The animals in group C, D, and E received 100mg/kg, 250mg/kg and 500mg/kg body weight of ethanolic extract of ginger respectively for fourteen days. Twenty four hours after the last administration, the animals were sacrificed; the pancreas was removed and processed in routine histological technique. Under the light microscope, the result showed normal exocrine part and disintegration of the islet cells (of Langerhans) with pyknotic nuclei. This study showed that the effect on the islet of Langerhan increases as the consumption increases
HISTOLOGICAL EFFECT OF THE LIVER FOLLOWING THE ADMINISTRATION OF ETHANOLIC ROOT EXTRACT OF ZINGIBER OFFICINALE (GINGER) IN MALE RATTUS NORVEGICUS (Published)
Zingiber officinale is one of the most widely used spices in the world for food additives. It contains zingiberone, shogaols, gingerols, pandols, β-phellandrene, curcumene, cineole, geranyl acetate, terphineol, terpenes, borneol, geraniol, limonene, β-elemene, zingiberol, linalool, α-zingiberene, β-sesquiphellandrene, β-bisabolene, zingiberenol and α-farnesene. It is one of the medicinal herbs used to treat several ailments such as cold, headache, nausea, stomach upset, diarrhoea digestive, gastrointestinal disturbances, rheumatic complains, asthma and parasitic infections. The liver is the largest viscera in the body and performs several functions such as removal of waste product and worn out cells from the blood, converting drugs into forms that can be eliminated easily etc. Liver functions can be hindered by numerous substances such as medicinal herbs ingested on daily bases. This study aimed at elucidating the cytoarchitectural distortion of the liver following the administration of ethanolic root extract of ginger using ratus norvegicus. 35 rattus norvegicus weighing 125- 200g were divided into five groups designated A, B, C, D & E. A & B were the control groups and the experimental groups C, D & E received 100mg/kg, 250mg/kg & 500mg/kg of ethanolic root extract of ginger respectively for fourteen days. The results showed constricted sinusoids, constriction of central veins and pyknotic cell nuclei. The above result showed that ethanolic root extract of ginger could distort the liver cells and this is attributed to prolonged administration and dose dependent.
