Abstract For food industry, the production of functional pasta from non-conventional raw materials represents a challenge. This study aims to evaluate the potential of animal proteins of freeze-dried whey as a component for pasta production and its effect on the pasta qualities and consumer acceptance. Sweet whey was freeze-dried, then directly incorporated to pasta at a 20% level. Two pasta types (pasta non-enriched vs. enriched with whey powder) were manufactured following a small-scale pilot procedure, and then evaluated for their physicochemical and sensory qualities. Results of all analyses (whey, semolina and pasta) met the standards according to international legislation; however, the characteristics of enriched pasta differed. Whey addition significantly increased ash, proteins content, optimal cooking time and water uptake (P < 0.05); it significantly decreased moisture levels, colour parameters (CIE system: a* redness, b* yellowness) and the swelling index (P < 0.05). Sensory analysis revealed that overall sensory and product quality of enriched pasta was not affected by whey fortification and it was found acceptable by panelists. This study points out that whey powder could be used for the functional pasta production to increase proteins levels.

The quality of Dakuwa can be affected by raw materials and processing methods. This work studied the effects of groundnut (Arachis hypogea L.) varieties (Campala, white and Sere) on the colour, flavour profile and sensory properties of Dakuwa. The flavour profile of the Dakuwa samples was analysed with gas chromatography – mass spectroscopy (GC – MS), colour by chroma meter and proximate composition using standard methods while sensory evaluation was done by 25 untrained panelists. The results were analysed using one way analysis of variance. Dakuwa sample with Campala groundnut (DKWC) had the highest concentration of alcohols (20 μg /100 g), aldehydes (86 μg /100 g), ketones (1.9 μg /100 g),  heterocyclic aromatic compounds (11.2 μg /100 g), and total flavour compounds (151 μg /100 g) suggesting higher lipid oxidation and Maillard reaction compared to Dakuwa with Sere and White groundnuts.  DKWC had significantly lower L* (lightness) value and significantly higher browning index (84.75) suggesting a higher browning reaction compared to other samples. Sensory evaluation results indicated no significant (p > 0.05) difference in the samples. It can be concluded that any of the three groundnut varieties can be used to produce Dakuwa without altering its sensory qualities.

Background: Honey is largely used on a small scale as well as at an industrial level in beverages, baked products, confectionaries, candies, marmalades, jams and spreads. The nutritional value of honey is very high and it is highly acceptable by the consumers due to its characteristic flavour, sweetness and texture. Hence, a study was conducted to improve the quality of value added goat meat spread enriched with honey. Methods: Honey at different levels viz. 0, 1.0%, 3.0% and 5.0% was incorporated in the value added goat meat spread for which instrumental colour, physico-chemical properties and sensory quality analysis was carried out. Result: Redness (a*) score increased significantly (p less than 0.01) high in goat meat spread after incorporation of honey but in the lightness and yellowness score there was a non significant (p greater than 0.05) increase noticed. There was no significant effect on hue and chroma due to incorporation of honey in goat meat spread. Cooking yield and spreadability were highly significant (p less than 0.01) and they increased with the increasing levels of honey as compared to control whereas, pH was decreased non significantly (p greater than 0.05). Moisture content of meat spread decreased significantly (P less than 0.05), whereas protein content increased signiûcantly (P less than 0.05) with the increasing levels of honey. Sensory qualities in respect to appearance, flavor, spreadability, texture, after taste, adhesive ability and overall acceptability score were found to be significantly (p less than 0.01) increasing in 3% incorporated honey as compared to control, 1% and 5%. On the basis of all the above observations it was concluded that 3% incorporation of honey improved the quality of goat meat spread.

Prunus domestica L. is one of the most commonly grown fruit species in Bulgaria due to its high ecological adaptation and multiple ways of fruit marketing. Fruit quality is associated with attributes such as appearance, texture, taste and colour. Breeding and new cvs. introduction are in constant search for cultivars with better fruit quality that would answer the increasing consumer requirements. In 2013 the Romanian plum cvs. ‘Pitestean’, ‘Roman’, ‘Romanta’, ‘Carpatin’ and ‘Tita’ were introduced in Bulgaria and planted in a collection orchard at the Fruit Growing Institute, Plovdiv. The study was conducted in the period 2016-2021. It aimed to evaluate the fruit quality when the cultivars are grown under the agro-environmental conditions of the region. For obtaining this objective, fruit weight, fruit flesh firmness, TSS (°Brix), skin colour with and without wax bloom and fruit flesh colour were measured. For evaluating consumer acceptance, a sensory analysis was performed. ‘Roman’ had the largest fruits with an average fruit weight of 46.66 g and the highest TSS content – 18.2°Brix. There were significant differences in the colour parameters L*, a*, b*, Chroma and Hue between the cultivars and the wax bloom had a significant effect on colour parameters. All fruits were appreciated by the testing panel of consumers and their taste qualities were evaluated as good and very good.

Diet diversification as well as a sustainable supply of the raw materials for utilization in processing salted eggs leads to an increase in the demand and consumption of salted duck eggs in the Philippines. In this study, the physicochemical, nutritional and sensory properties of salted duck eggs made in the laboratory were evaluated. Physicochemical properties revealed that the sample collected registered a pH and water activity of 7.1 and 0.88, respectively. In addition, the samples showed a total colour difference of 15.01 using the Hunter scale system. The samples exhibited an average of 1.03% salt content. Furthermore, proximate composition, mineral and fatty acid analyses of samples proved that a considerable amount of these nutrients were present in salted duck eggs that were analysed. Protein, fat, carbohydrate, crude fibre and ash content were 11.49, 10.15, 3.54, 1.07 and 1.01%, respectively. On the other hand, minerals such as phosphorus, potassium and calcium were recorded at 4.46, 3.92 and 3.61 mg/100 g, respectively. In general, the major fatty acids found in the samples were oleic acid (C18:1), myristic acid (C14:0) and linolenic acid (C18:2). Sensory evaluation revealed that flavour was regarded by the panellist as a major consideration in evaluating the quality of salted duck eggs. This study proved that salted duck eggs have nutritional and quality characteristics that can be considered as an alternative source of protein, fat and minerals for human consumption.

AbstractColour is one of the most important properties of cotton raw materials. It helps in determining and classifying the quality of fibres according to the Universal Cotton Standards. Organoleptic and instrumental techniques are applied to assess the color of cotton. Worldwide, the colour parameters of cotton are measured by the High Volume Instrument (HVI), which provides information on reflectance (Rd) and yellowness (+b) that is specific for cotton, but are not the typical and globally recognized colour characteristics. Usually, worldwide, the colour of textile products and other goods is assessed utilizing the spectrophotometer, which provides the colour data that is widely recognized and accepted by the CIE L*a*b* colour space. This paper discusses utilizing the DigiEye system to measure the colour parameters of cotton samples and compares the results with the colour parameters from the HVI.

The article raises the problem of ensuring metrological traceability of the measurement results of indicators of quality and nutritional value for food products and food raw materials: water (moisture), nitrogen (protein, crude protein), fat, ash and carbohydrates. The problem under consideration can be solved by applying reference materials of food composition, traceable to state primary measurement standards GET 173-2017 and GET 176-2019 and primary reference measurement procedures (PRMP), for attestation of measurement procedures and accuracy checking of measurement results. The article discusses the results of the PRMP development of mass fraction of fat, ash and carbohydrates in food products and food raw materials, as well as mass fraction of crude fat (oil content) in oil crops seeds and products based on them. The paper also presents metrological characteristics of reference materials of composition of dry dairy products, grain-milk dry porridges for nutrition of babies, grain dry porridges for nutrition of babies, egg powder, freeze-dried meat products, animal feed. The results of the work allow for building a chain of metrological traceability from GET 173-2017, GET 176-2019 and PRMP to routine measurement procedures, thereby ensuring the uniformity of measurements of nutritional value of food products.

Quality of Carrots Grown for Processing as Affected by Nitrogen Fertilization and Harvest TermIn 2007-2008 the effect of nitrogen fertilization and harvest term on quality of two carrot cultivars was investigated. The field experiment was carried out in Żelazna Experimental Station of Warsaw University of Life Sciences. Karotan F1and Trafford F1cultivars, commonly grown for juice industry, were the objects of the experiment. Carrot seeds were sown at the beginning of May. Nitrogen fertilization was applied in five rates, ranged from 0 to 120 kg·ha-1and in two terms — before sowing and in the middle of growing season. Roots were harvested in three terms: mid-September, mid-October and the first decade of November. After harvest there were determined: nitrates (NO3) content in carrot roots and juice, soluble solids, colour parameters of juice in CIE L*a*b*system. The dose and the term of nitrogen fertilization influenced nitrates content in carrots, and the highest NO3concentration was found in carrots fertilized with 120 kg·ha-1of N before sowing. Karotan showed higher nitrates accumulation than Trafford. The content of nitrates in the roots was markedly higher than in carrot juice. Nitrates content in carrots decreased with delaying of harvest time, in opposite to soluble solids content. Soluble solids content and colour parameters of carrot juice were not affected by nitrogen fertilization, but the lowest L*, a*and b*values were observed at the last term of harvest.
