Solid brem is one of Indonesian traditional food. The low level of antioxidant content might be increased by adding powdered spice formula which is rich in phenolic compounds. The objective of this study was to determine the effect of powdered spices formula on antioxidant activity and sensory quality of solid brem. The formulation of powdered spices was ginger, turmeric, cloves, nutmeg, pepper, and cinnamon in a ratio of 3: 1: 1: 1: 1: 0.5. Randomized Complete Block Design (RCBD) with six treatments of adding powdered spices formula (0, 1, 2, 3, 4, and 5%) and three replications were used as the method. The data were analyzed by analysis of variance (ANOVA) at a 5% significance level using Co-Stat software and tested further by Orthogonal Polynomial Method (OPM) or using Honestly Significant Difference (HSD). The result showed that adding powdered spices formula on solid brem had a significant different effect on antioxidant activity, water activity, pH value, physical quality (texture and color), and sensory quality (hedonic) on color, taste, texture, and melting in the mouth. The addition of 4% of the spices formula is recommended to produce the best quality of solid brem with the following characteristic: 80.51% of antioxidant activity, 15.71 mg GAE/g of material total phenol, 40.90% Brix of total dissolved solids, 0.55 water activity (Aw), 3.44 pH value, 9.08 N texture value (physical), and 84.68 oHue color value (physical). The product had light yellow; slightly spicy, solid and rather smooth texture, and melting in the mouth. The high content of antioxidant activity in the product proved the potential of using powdered spices in improving the antioxidant activity of solid brem.

The sensory quality of fresh basil (cv. Sweet Italian) was evaluated to determine if compost or mineral fertilizer applications affected flavor and aroma intensity. The four treatments, arranged in a randomized complete-block design with three replications, were: compost applied at 50 t·ha–1; compost applied at 200 t·ha–1; mineral N applied at 110 kg·ha–1; and a control receiving no amendment. Leaves from the first four nodes of young shoots were used in the evaluation. Twelve trained panel members scored samples of three leaves from each treatment for aroma and flavor intensity using a linear scale, converted to a scale of 1–10 where 1 = much less intense than a reference sample (control), and 10 = much more intense than the reference. No significant difference between treatments was found in flavor intensity. Significant difference between treatments in aroma intensity was found. Aroma scores were highest in samples from the compost and synthetic fertilizer treatments, and lowest in those from the control. Scores for aroma from the compost and synthetic fertilizer treatments were similar to each other. Aroma intensity increased with increased rate of compost application. No significant correlation was found between aroma intensity and plant tissue N content, sap NO3– levels, or yield.

Robusta coffee plant propagation is recommended to be performed by vegetative methods, one of which is cuttings. Among plant organs that can be used for cuttings is the stem. The research objective was to determine which stem segment from cuttings was able to provide the best root and leaf growth. The layout study used a completely randomized block design (RBD) with an experimental treatment consisting of five stem segments, namely (1) the first stem segment from the upper shoot (A); (2) the second stem segment from the upper shoot (B); (3) the third stem segment from the upper shoot (C); (4) the fourth stem segment from the upper shoot (D); and (5) the fifth stem segment from the upper shoot (E); each treatment had five replications. Data analysis was performed statistically with analysis of variance (ANOVA) and Tukey's HSD (honestly significant difference) test with a significance level of P < 0.05. Robusta coffee cuttings stems from the second stem segment from the upper shoot were able to provide the optimal root growth (root length) and shoot growth (leaf sprout height and leaf sprout growth rate). Leaf sprout number derived from the cuttings was not affected by the stem segment.

PurposeThe aim of the study reported in this article was to establish whether the quality of clothes of a given brand is perceived and assessed by consumers at the same level. An additional purpose was to identify the features that characterize the quality of popular, among Polish young female consumers, clothing brands and to classify them according to their quality level (perceived and assessed).Design/methodology/approachThe article presents two approaches to consumer assessment of the quality of clothes: the survey method, in which the product quality was determined by 320 Polish female young respondents (19–25) based on their own previous experiences and impressions related to a particular clothing brand, and a direct assessment of shirts of selected brands using a sensory quality assessment method, a five-point hedonic scale with the verbal anchor (115 evaluators).FindingsThe research has revealed a significant difference between the perception of selected quality features of brands and the consumer assessment of the products. The perception maps developed based on the PROFIT analysis (PROperty FITting) as well as on cluster analysis provided interesting information about the situation of selected brands and their features in comparison with others and allowed to identify strong and weak features characterizing a given category.Research limitations/implicationsThis study has several limitations. First and foremost, the research results cannot be generalized to all consumers because they encompass the results from one national context and one population of respondents (young females). It should also be noted that the conducted research comprises only the most popular clothing brands available on the Polish market, in particular, the fast fashion segment brands. Furthermore, it would be advisable to carry out a sensory assessment of the quality of other clothing items offered under the brand names investigated.Practical implicationsThis research could be a valuable source of information for clothing company managers, thanks to which they could better manage their brand and its position on the market. When undertaking marketing activities consisting of building positive perceptions about the product, it is important to make sure that the product offers an attractive sensory experience. When real quality deviates from consumer perceptions about the quality, managers should take corrective actions to restore and even improve the brand image in the eyes of the consumer, as well as to ensure the brand and the products offered under it a stable position on the market.Originality/valueBy comparing two approaches to consumer quality assessment, discrepancies between declared and real (sensory) quality of clothes have been identified and the distinctive features that differentiate selected brands regarding their quality level have been indicated.
