This study aimed to evaluate the effect of sucralose added in Greek Yogurt flavored with araticum (Annona crassiflora) and mangaba (Hancornia speciosa) through sensory characterization. The Greek yogurt was prepared with skimmed milk, inoculated starter cultures, filtered and it was supplemented with the appropriate amount of sucralose, added sweetened and pasteurized fruit pulp (araticum or mangaba). The total phenolic compounds and texture were performed and sensory analyses were carried out by Quantitative descriptive analysis (QDA) and acceptance test in storage for 7 and 28 days. The QDA results showed that the main attributes were color, lightness, creaminess, presence of particles, fullness, and aroma. Eighty percent and 85% of the panelists were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after 7 days of storage, respectively. Additionally, 71% and 77% were said they would buy the araticum Greek yogurt and the mangaba Greek yogurt after storage for 28 days at 4ºC, respectively. The sensory profile and acceptance test results of the Greek yogurts developed indicated no perceptions caused by adding sucralose to the yogurt after storage for different times. The highest concentration of phenolic compounds in the araticum Greek yogurt was perceived by the panelists in aroma and flavor attributes. Changing sucrose to sucralose was not imperceptible under the storage and consumption conditions.

Recommendations for consuming industrialized whole grain foods have been encouraged. The present study produced new functional foods and sought to identify the sensory profile of the foods processed. Four types of dried spaghetti were manufactured with different formulas, regarding their whole grain flour and linseed content (10 and 20%). For evaluation of the products obtained, the following methods were employed: sensory analysis of acceptance using a 9-point hedonic scale, applied to 50 trained judges, and Quantitative Descriptive Analysis (QDA) using a 9-cm unstructured line scale. Results were analyzed by ANOVA and Tukey’s test at 5% significance, and the sensory profile was expressed in the form of a spider graph. Acceptance test revealed no difference between the pasta containing 10% and 20% of whole grain and 10% of linseed. Results indicate acceptance of the 20% whole grain product regarding its raw texture and consistency when cooked, in addition to the possibility for the manufacture and acceptance of 10% linseed spaghetti.

In recent years, non-alcoholic beers have presented a growth considered satisfactory and exciting for the brewing industry. Such growth is allied to a change in the consumer profile, in addition to changes in traffic laws. However, the consumer seeks a product considered healthier, but as tasty as the original. Thus, this study aimed to identify the influence of the alcoholic factor in sensory profile, through quantitative descriptive analysis and time intensity analysis of Pilsen beer samples. An acceptance test with 120 consumers of beer was performed. A quantitative descriptive analysis was carried out by 11 trained assessors to determine the sensory profile of beers. For identification of influences of alcohol factor in the dynamic profile of alcoholic flavor and bitter taste the time-intensity analysis were realized. The results demonstrate that alcohol factor influences both the quantitative descriptive profile and dynamic profile, in addition the correlations between the quantitative descriptive analysis (QDA®) and hedonic data show that the alcoholic flavor and the alcoholic aroma are attributes that contribute positively to acceptance of samples. In view of the results, studies such as the present are of great importance for the improvement of product quality, directly reflecting a greater acceptance of beer consumers.

Tape ketan (fermented glutinous rice) and tape singkong (fermented cassava) are traditional Indonesian foods produced by fermenting carbohydrate sources using ragi as starter culture. Those products known to contain high number of lactic acid bacteria (LAB). The purpose of the study was to evaluate the sensory characteristics of tape ketan and tape singkong from different household industry in Bogor, to identify the sensory profile, and to evaluate the correlation between LAB density and sensory attribute. The research was started by survey to household tape industries, followed by sensory analysis of rating hedonic and Quantitative Descriptive Analysis (QDA), and LAB analysis. Data analysis of rating hedonic was done by ANOVA and post-hoc Duncan test, while data analysis of QDA was done by Principle Component Analysis (PCA). Samples of tape ketan were taken from two different home industries (BK and LK), while samples of tape singkong were taken from four different home industries (CT, NG, SH, TS). Hedonic rating test showed that the most preferred sample overall was tape ketan BK and tape singkong CT. QDA results showed that tape ketan BK was characterized by its sweetness, rice-like aroma, rice-like taste, and texture, while tape ketan LK was characterized by alcoholic aroma, alcoholic taste, sourness, and color. Tape singkong NG were characterized by sour aroma, alcoholic aroma, alcoholic taste, and color. Specific characteristic of tape singkong CT was bitterness and bitter aftertaste, SH was sweetness, and TS was texture. LAB of tape ketan BK (8,5 log cfu/g) was higher than LK (7,9 log cfu/g). Tape singkong with highest density of LAB was TS (8,1 log cfu/g), followed by CT (7,2 log cfu/g), NG (7,0 log cfu/g), and SH (6,5 log cfu/g). There was no correlation between the density of LAB and descriptive score of sourness, alcoholic taste, and sweetness.

This work aimed to study the physical, structural, and sensory properties of a traditional full-fat mayonnaise (≈ 80% oil) enriched with an olive leaf phenolic extract, added as either free extract or encapsulated in alginate/pectin microparticles. Physical characterization of the mayonnaise samples was investigated by particle size, viscosity, lubricant properties, and color; a sensory profile was also developed by a quantitative descriptive analysis. The addition of the extract improved the dispersion degree of samples, especially when the olive leaf extract-loaded alginate/pectin microparticles were used. The encapsulated extract affected, in turn, the viscosity and lubricant properties. In particular, both of the enriched samples showed a lower spreadability and a higher salty and bitter perception, leading to a reduced overall acceptability. The results of this study could contribute to understanding the effects of the enrichment of emulsified food systems with olive by-product phenolic extracts, both as free and encapsulated forms, in order to enhance real applications of research outcomes for the design and development of healthy and functional formulated foods.

Defatted sunflower seed flour (DSSF) is an upcycled by-product of sunflower oil extraction, rich in protein, fibre and antioxidants. This study assessed the instrumental and sensory quality of biscuits enriched with DSSF at 18% and 36% w/w as a replacement for wheat flour. Measurements included colour, texture, total phenolic content (TPC) and antioxidant capacity. Sensory analysis was carried out with Quantitative Descriptive Analysis (QDA). The inclusion of DSSF significantly increased the protein content of the biscuits, as well as the TPC and antioxidant capacity of the biscuits. The resulting products were significantly darker, less red and less yellow with increasing DSSF levels, while hardness (measured instrumentally) increased. Sensory results agreed with colour measurements, concluding that DSSF biscuits were more “Brown” than the control, and with texture measurements where biscuits with 36% DSSF had a significantly firmer bite. In addition, DSSF biscuits at 36% inclusion had higher QDA scores for “Off-note” and the lowest scores for “Crumbly” and “Crumb aeration”. DSSF biscuits at 18% inclusion were similar to the control in most parameters and should be considered for further developments. These results show the potential of the upcycled DSSF by-product as a novel, sustainable and healthy food ingredient.
