Formulation and evaluation of fast dissolving tablets of captopril

Oral administration is the most popular route for systemic effects due to its ease of ingestion, pain, avoidance, versatility and most importantly, patient compliance. The development of enhanced oral protein delivery technology by mouth dissolving Tablets which may release these drugs in the mouth are very promising for the delivery of high molecular weight protein and peptide. Good mouth feel property of MDDS helps to change the basic view of medication as “bitter pill”, particularly for pediatric patients. To prepare mouth dissolving tablet using SSG & CCM by using Antihypertensive as model drug. Captopril is a potent, competitive inhibitor of angiotensin-converting enzyme and it is a key component of the renin-angiotensin-aldosterone system. The ƛmax of Captopril was determined by scanning the 10µg / ml solution of drug using UV-Spectrophotometer and was found to be 271nm. The linear correlation was found to be 0.9995.The Fast dissolving tablets of captopril were prepared by direct compression method. Captopril can be successfully formulated as mouth dissolving tablets using various super disintegrate in different concentrations by direct compression method. The formulation containing 10% of crospovidone as super disintegrated was found to be outstanding than other formulations in terms of disintegration time and rate of dissolution.

Sensory optimization of formulated coffee mix from pedada seed (Sonneratia caseolaris) and robusta coffee (Coffea canephora)

Pedada seed is one of potential anti-oxidant resources of coastal plants which is under-utilized. In this current study, pedada seed was formulated in to Robusta coffee to develop a novel coffee mix. The purpose of this study was to obtain the most ideal formula of pedada-Robusta coffee mix based on sensory evaluation using Just about Right (JAR) analysis of French-press brewed coffee mix. The best coffee mix formula was obtained for the mix of 1:1 proportion between pedada seed and Robusta coffee. There were 18 out of 19 sensory attributes of the best formula that sensorially accepted by the consumer respondents. Those included vegetative aroma, brown sugar aroma, musty aroma, sweet aroma, nutty aroma, cocoa aroma, citrus-fruit aroma, sweet taste, sour taste, body-mouth-feel, mouth-feel strength, nutty flavour, burnt flavour, chemical flavour, citrus-fruit flavour, beany flavour, roasted flavour and sweet flavour. The best pedada-coffee mix was also characterized as having mean particle size of 421.5±19.1 μm, total phenolic content of 21.55±0.21 mg GAE/g, antioxidant activity of 48.60±0.94%, caffeine content of 278.50 ± 4.95 mg/kg, total dissolved solids of 0.4±0.066% and colour with a value of L=17.0±0.0; a=18.6±0.9 and b=23.6±0.9.

Effect of Blending Ratio of Mango Juice on Physicochemical and Sensory Acceptability of Soya Yoghurt, Southern Ethiopia

This study was conducted on effect of blending ratio of mango juice on physicochemical and sensory acceptability of soya yoghurt. To evaluate physicchemical (PH, TSS and titrateble acid) and sensory acceptability (color, taste, flavor, mouth feel and overall acceptability), four formulations of soya yoghurt samples were prepared from blending ratio of 100:0% (S1 ), 90:10% (S2 ), 80:20%(S3 ), 70:30% (S4 ) soya yoghurt and mango juice, respectively. Designs of the study were Completely Randomized for physicochemical properties and randomized complete block design for sensory acceptability with four treatments and three replications. Physicochemical properties (PH and TSS) of soya yoghurt samples had shown significant difference (p< 0.05) in mean scores, but titrateble acid of soya yoghurt samples had not shown significant difference (p<0.05) in mean scores when the amount of mango juice were increased in blending ratio. Sensory acceptability of soya yoghurt samples were increased as increase the amount of mango juice in blending ratio except color when panelists were evaluated. Soya yoghurt sample four (S4 ) had highest mean scores of sensory acceptability (flavor = 4.65, taste = 4.53, mouth feel = 4.37 and overall acceptability = 4.93) as compared to other soya yoghurt samples. Control (S1 ) soya yoghurt sample had highest mean score (4.67) of color than other soya yoghurt samples. Based on result of this study, soya yoghurt sample four (S4 =70% soya yoghurt: 30% mango juice) was recommended to increase sensory acceptability of soya yoghurt that is important for milk intolerance children. Further study will be needed on nutritional composition of soya yoghurt samples blended with mango juice.

Proximate Composition, Phytochemical, Mineral and Sensory Analyses of Moringa oleifera Enriched Bread

Aim/background: The study investigated the effect of Moringa oleifera powder on enriched bread samples produced at various levels. Wheat flour and moringa powder were formulated at different percent ratio (1%, 2%, 3% and 4%) to determine the best enrichment ratio. Methods: Proximate, phytochemical, mineral content and sensory evaluation of the bread samples were determined using bread made from 100% wheat flour which served as control. Results: Result for proximate composition showed a progressive drop (p<0.05) in the fibre content of the enriched bread samples with decreasing level of enrichment. The energy value of the bread samples ranged from 392.73 to 394.32 Kcal. For crude protein, sample with 4% moringa enrichment recorded the high protein content which recorded a value of 12.89 %, which was significantly different (p<0.05) from other samples. The sample with 4% moringa enrichment recorded the highest ash content value of 2.67 % and was significantly different (p<0.05) from the other samples. Result of sensory evaluation using a nine-point Hedonic scale showed that enriched bread samples recorded 5.10 to 7.65 for appearance, 5.45 to 6.85 (aroma), 5.35 to 7.75 (texture), 5.55 to 7.70 (mouth feel) and 5.55 to 7.60 (general acceptability). Conclusion: The enrichment of bread products could be best achieved at moringa levels of 2 % and 4%.

Determination of the Best Method of Dehydration of Tropical Fruits to be Incorporated in Gelatin-based Dessert with Unaltered Sensory Qualities

Background: Jelly based desserts are very popular among millions of people worldwide. The main gel forming ingredient used in these products is ‘Gelatin’, which is a complex polysaccharide in their chemical structure. This research study focusses on incorporation of fruit pieces in to the dessert jelly in order to give a novel experience to the consumers. Methods: To determine the best way of incorporating fruit pieces in a commercially available jelly mixture (which is made up of fruit flavour, acid, water, sugar and pectin as the jelling agent), fruit pieces were treated in two ways and compared for the best textural and sensory qualities. First sample constituted unblanched, oven dried fruit pieces in a commercially available jelly mixture and its was compared with a jelly sample with blanched (fruit pieces were pretreated to minimize any possible discolorations and textural changes), osmo air dehydrated and oven dried fruit pieces. Sensory qualities such as texture, mouth feel and flavour of two different samples were gauged through a sensory test. Result: From a sensory test carries out by a panel of 09 sensory panelists it was found that the jelly mixture when incorporated with osmo air dehydrate fruit pieces it did not degrade the texture of the final product as opposed to unblanched dried fruit pieces does. The osmo air dehydrated fruit pieces in the prepared jelly has a texture and an acceptable mouth feel which is closer in texturally to the natural mouth feel and the taste, when they are reconstituted inside the jelly mixture by absorbing the water from the mixture.

Papaya (Carica papaya L.) Flavour Profiling

A major challenge to the papaya industry is inconsistency in fruit quality and, in particular, flavour, which is a complex trait that comprises taste perception in the mouth (sweetness, acidity, or bitterness) and aroma produced by several volatile compounds. Current commercial varieties vary greatly in their taste, likely due to historical prioritised selection for fruit appearance as well as large environmental effects. Therefore, it is important to better understand the genetic and biochemical mechanisms and biosynthesis pathways underpinning preferable flavour in order to select and breed for better tasting new commercial papaya varieties. As an initial step, objectively measurable standards of the compound profiles that provide papaya’s taste and aroma, together with ‘mouth feel’, are required. This review presents an overview of the approaches to characterise the flavour profiles of papaya through sugar component determination, volatile compound detection, sensory panel testing, as well as genomics-based studies to identify the papaya flavour.

Physical and Sensory Properties of Bread Made with Wheat and Fermented Finger Millet (Eleusine coracana L.) Flours

Aim: The study was conducted to determine the effect of fermented finger millet flour supplementation in wheat on the physical and sensory properties of bread. Methodology: Finger millet grains were cleaned, washed and fermented in deionized water for 72 h at room temperature (27±2oC), with sampling at every 24 h interval. Fermented grains were washed, drained, dried (65oC, 4 h), milled and sieved (<250 µm) to produce Fermented Finger Millet Flour (FFMF). Composite flour was formulated by supplementing wheat flour with Fermented Finger Millet Flour (FFMF) at 0, 5, 10, 15 and 20 % (w/w), and used to produce bread samples. Physical (Oven spring, loaf weight, loaf volume and specific volume) and sensory (crust colour, crumb colour, aroma, texture, taste, mouth feel and overall acceptability) properties of the bread samples were determined. Results: Physical properties showed less oven spring, loaf volume and specific loaf volume and increased loaf weight with increased FFMF replacement. The sensory analysis showed significant differences (p<0.05) between 100% wheat bread and FFMF supplemented samples in all the determined sensory properties. It was concluded that fermentation period of 24-48 h, and substitution of 5-10% FFMF into wheat gave the bread samples with the best overall acceptability.

Organoleptic properties and shelf-lives of differently dried fowl eggs

Poultry eggs are perishable, hence could lose their quality rapidly between storage and consumption. Maintaining fresh quality is a major problem which is aggravated by temperature, humidity, storage method and time. Several methods of altering these environmental conditions to prolong the shelf-life of the eggs have been reported, yet little is known about kiln, solar and oven methods of drying boiled fowl eggs. This study was targeted at creating awareness, evaluating the organoleptic properties and determining the shelf-life of kiln-, solar- and oven-dried fowl eggs, stored under different environmental conditions. A total of 160 Isa brown freshly laid eggs were obtained and weighed, and were divided into four different groups of 40 eggs each, designated as control, kiln-, solar- and oven-dried. The eggs were boiled for 30 minutes and dried at 100 – 120oC overnight (kiln dried), 45 – 50oC for 5 days (solar dried) and 100oC for 24 hours (oven dried), but those in the control group were not dried. Panelists were used in obtaining information on awareness of fowl eggs drying/drying methods and organoleptic evaluation. Twenty-seven eggs each from the control, kiln-, solar- and oven-dried groups were kept in locally fabricated egg packs and stored for 30 days in a sales outlet, deep freezer and kitchen for shelf-life determination. Results showed that egg weight loss was highest (52.3%) in the kiln-dried, followed by oven-dried (38.9%), solar-dried (27.4%) and control (20.6%) groups. All the panelists (100%) were aware of the different forms of storing boiled fowl eggs and have eaten fowl eggs in different forms, but none (0.0%) was aware of kiln, solar and oven method of drying fowl eggs, or has eaten kiln-, solar- and oven-dried fowl eggs before then. Some of the panelists liked the appearance, taste, aroma, mouth feel, after-taste and overall acceptability of the dried eggs. All (100%) of the eggs in the sales outlet spoilt, but none (0.0%) among the dried eggs stored in the deep freezer was spoilt. In the kitchen, all the control eggs (100%), 22.2% (kiln dried), 88.9% (solar dried) and 66.7% (oven dried) spoilt. Kiln- and oven-dried eggs had more water loss, apparently implying better effectiveness of the drying methods. Therefore, fowl eggs could be boiled, dried and refrigerated to elongate their shelf-lives.

Can Food Be Art in Virtue of Its Savour Alone?

Food has savour: a collection of properties (including appearance, aroma, mouth-feel) connected with the pleasure (or displeasure) of eating. This paper argues that savour is aesthetically evaluable —it is not merely “agreeable”. Further, like paradigm examples of art, savour can be assessed by how it references, or “exemplifies”, cultural norms. This paper is part of a larger project in which I develop an account of the pleasure of art. It is a virtue of my approach that it permits a much greater diversity of artforms than traditional philosophical aesthetics is inclined to allow. This includes food.

Fermented Millet “Ibyer” Beverage Enhanced with Ginger Powder: An Assessment of Microbiological, Pasting, Proximate, and Sensorial Properties

A fermented millet flour called “Ibyer” traditionally available in Nigeria is increasingly being enhanced with ginger powder, of which its quality characteristics to our best knowledge appears not yet reported. To supplement existing information, therefore, the microbiological (which involved bacteria and fungi counts), pasting (which involved peak viscosity, trough, breakdown, final viscosity, set back, peak time, and pasting temperature), proximate (which involved moisture, ash, crude fat, fiber, protein, as well as carbohydrates), and sensory (which involved appearance, aroma, mouth-feel, consistency, taste, and overall acceptability) properties of fermented millet “ibyer” beverage enhanced with ginger powder were investigated. The major experimental stages included assembly of millet flour and ginger powder, preparation of blend formulation, making of “ibyer” beverage blends, and laboratory analysis. The blend involved fermented millet flour (FMF) decreasing, and ginger powder (GP) increasing, by proportions. Results showed noticeable microbiological, pasting, proximate, and sensory differences between blend samples and control. Compared to control, the blend samples obtained reduced bacterial and fungal counts, with increased peak, trough, final, set back viscosities, peak time, and pasting temperature, as well as moisture, ash, crude fat, crude fiber, and crude protein contents, but yet, with decreased sensory appearance, aroma, mouthfeel, taste, and overall acceptability.
