Antioxidant and Sensory Assessment of Innovative Coffee Blends of Reduced Caffeine Content

Considering the current trend in the global coffee market, which involves an increased demand for decaffeinated coffee, the aim of the present study was to formulate coffee blends with reduced caffeine content, but with pronounced antioxidant and attractive sensory properties. For this purpose, green and roasted Arabica and Robusta coffee beans of different origins were subjected to the screening analysis of their chemical and bioactive composition using standard AOAC, spectrophotometric and chromatographic methods. From roasted coffee beans, espresso, Turkish and filter coffees were prepared, and their sensory evaluation was performed using a 10-point hedonic scale. The results showed that Arabica coffee beans were richer in sucrose and oil, while Robusta beans were characterized by higher content of all determined bioactive parameters. Among all studied samples, the highest content of 3-O-caffeoylquinic acid (14.09 mg g−1 dmb), 4-O-caffeoylquinic acid (8.23 mg g−1 dmb) and 5-O-caffeoylquinic acid (4.65 mg g−1 dmb), as well as caffeine (22.38 mg g−1 dmb), was detected in roasted Robusta beans from the Minas Gerais region of Brazil, which were therefore used to formulate coffee blends with reduced caffeine content. Robusta brews were found to be more astringent and recognized as more sensorily attractive, while Arabica decaffeinated brews were evaluated as more bitter. The obtained results point out that coffee brews may represent a significant source of phenolic compounds, mainly caffeoylquinic acids, with potent antioxidant properties, even if they have reduced caffeine content.

Physicochemical properties, nutrient profile, microbial stability, and sensory evaluation of cupcakes enriched with pomegranate seed oil

Excessive use of refined flour, solid fats, and sugar in preparing baked products are considered to be unhealthy and is intricately linked with the development of lifestyle diseases. Replacing refined flour with whole wheat flour and solid fats with cold-pressed oil serves as an alternate option. The study was aimed at evaluating the physicochemical properties, nutrient composition, sensory attributes, and shelf life of cupcakes enriched using pomegranate seed oil (PSO). Vanilla and chocolate cupcake variants were prepared using 25 and 50% of PSO. A sensory panel consisting of 30 semi-trained participants was selected for evaluating the formulated products using a five-point hedonic scale. Nutrient content was estimated using standard techniques. The stability of the formulated product was determined by evaluating the physicochemical traits and microbial growth on the 0th, 4th, and 7th day. Mean scores of the sensorial analysis showed that the incorporation of PSO in cupcakes was highly accepted by the panel members. Chocolate cupcake containing 50% of PSO was found to be the most preferred product (3.53±0.94), followed by vanilla cupcake containing 25% of PSO (3.4±0.62). The moisture, protein, and fat content of chocolate cupcakes containing 25% of PSO were high. Cupcakes prepared with PSO can be stored for four days at room temperature. GC-MS analysis showed the presence of punicic acid, oleic acid, tocopherols, campesterol, sitosterols, stigmasterol, and α-tocopheryl acetate as pre-dominant fatty acid in unheated and heated PSO. In conclusion, cupcakes prepared using PSO showed acceptable physicochemical qualities and sensory properties which indicated its successful consumption by people affected with metabolic disorders.

Physico-Chemical, Nutritional, and Sensory Evaluation of Two New Commercial Tomato Hybrids and Their Parental Lines

Tomato (Solanum lycopersicum) is the globally most consumed vegetable. The objective of this research was to analyze physico-chemical, nutritional and sensorial components (taste and flavor) in two new commercial hybrids (AS 300 F1 and AS 400 F1) and their four F7 parental lines. Two widely grown F1 hybrids (Precos F1 and Addalyn F1) were used as controls. The results obtained for carbohydrates (HPLC-RID) indicated that the highest values (27.82 mg/g) were recorded in the paternal line AS 10 of the new hybrid AS 400 F1. The highest values of total organic acids (HPLC-VWD) were recorded in Addalyn F1 (5.06 m/g), while the highest value of phenolic compounds (HPLC-DAD-ESI⁺) were identified in the maternal line AS 09 of the hybrid AS 400 F1 (96.3 µg/g). Intrinsic sensory values were analyzed by male and female tasters of different ages using a hedonic scale. The tasters’ perception revealed obvious taste differences between tomato genotypes. The study allowed determining genetic parameters of interest (heterosis and heterobeltosis) for the new hybrids, as well as a detailed characterization of the chemical composition and organoleptic quality of the parental breeding lines and their hybrids, which is useful in tomato breeding.
