Specialty coffee is generally found in areas with an altitude around 1000 meters above sea level (m a.s.l.) and is known to have a different distinctive flavor. One of the coffee plantations in South Sulawesi that has the potential to upgrade its status as a specialty coffee is the Sinjai regency. The sensory quality and chemical characteristics are the most important component of specialty coffee. The purpose of the study was to evaluate the chemical compounds and sensory quality in Manipi coffee beans in South Sulawesi, which has the potential to be classified as specialty coffee. The coffee cherries were collected from two locations based on different altitudes namely MA1 = 1200 m a.s.l. and MA2 = 1400 m a.s.l. The coffee cherries directly processed the wet method referring to Enrekang Arabica as a reference sample EA1 = 1200 m a.s.l. and EA2 = 1400 m a.s.l. The results showed that the chemical content and quality of sensory in Manipi Arabica coffee beans were affected by altitude. MA2 had the highest protein content (13.26%), lipid (7.67%), and caffeine (1.42%), whereas green arabica coffee beans with the highest carbohydrate content was MA1 (23.38%). The Enrekang Arabica were similar in terms of Manipi Arabica coffee beans had the highest protein, lipid, and caffeine content at an altitude of 1400 m a.s.l. respectively (12.41%), (10.73%), and (1.32%). The sensory quality of MA1 is 85.75, relatively similar to MA2 is 85.25. The Manipi Arabica coffee beans showed a specific flavor, namely brown sugar and vanilla notes from both altitudes. It had the potential to be developed into specialty coffee with a cup test score > 80.

ABSTRACT Specialty coffees can be differentiated in various ways, including the environmental conditions in which they are produced and the sensory composition of the drink. This study aimed to evaluate the effect of altitude, slope exposure and fruit color on the sensory attributes of cafes of the region of Matas de Minas. Sampling points were georeferenced in four altitude ranges (< 700 m; 700 ≤ x ≤ 825 m, 825 < x < 950 m and ≥ 950 m) of the coffee crop; two fruit colors of var. Catuaí (yellow and red); and two slope exposures (North-facing and South-facing). Coffee fruit at the cherry stage were processed and submitted to sensory analysis. The sensory attributes evaluated were overall perception, clean cup, balance, aftertaste, sweetness, acidity, body and flavor, which made up the final score. The scores were examined by ANOVA and means were compared by the Tukey test (p ≤ 0.05). From the sensory standpoint, coffee fruits of both colors are similar, as well as the coffees from both slope exposures when these factors were analyzed separately. However, at higher altitudes, Yellow Catuaí produces coffees with better sensory quality. Similarly, coffees from North-facing slopes, at higher altitudes produce better quality cup. The altitude is the main factor that interferes with coffee quality in the area. All factors together contribute to the final quality of the beverage produced in the region of Matas de Minas.

ABSTRACT: Sensory characteristics were evaluated such as aroma, taste, aftertaste, acidity, body, consistency, balance, cleanliness of the cup, sweetness and beverage quality of four coffee cultivars (Catuaí, Caturra, Pache and Catimor) harvested from two different attitudes [sic: altitudes] (800-1000 and 1000-1200 meters above sea level) in the Province of San Martin - Peru. The focus of this research was to look for significant differences between sensory characteristics evaluated by 05 professional coffee-tasters certified by the Cooperativa Agraria Cafetalera y de Servicios Oro Verde. Ripe cherries were hand-picked, wet processed with natural fermentation and last of all submitted to solar drying. The roasting and grinding procedures followed those specified by the Specialty Coffee Association of America. The coffee-tasters evaluated the sensory attributes on a scale of 6-10 for each criterion. Our results suggested that the sensory quality of Pache and Caturra coffee beans increases the higher the altitude they are cultivated. Although, there is no significant difference between altitudes, the interaction between these two varieties and altitude favors a greater gain in beverage quality as well as aroma, flavor and acidity for the Caturra variety.

<p>Biochemical composition appears to be influenced by both genetic factors and plant growth conditions. The main objective of this study was to evaluate the biochemical composition of selected Ruiru 11 sibs and its relationship with cup quality. Thirty four (34) Ruiru 11 sibs grown in three different locations in Kenya were used in this study. The experiment was laid out in a Randomized Complete Block Design with three replications. Coffee cherries were picked during the peak harvesting period between 2009 and 2011. The cherries were wet processed and graded into different grades based on size, shape and density. Fifty (50) grams of the dry coffee beans per sib per replication were frozen at -80 ºC before grinding (< 0.5 mm particle size) in liquid nitrogen as specified by the Association of Official Analytical Chemists (AOAC). The samples were packed in small plastic bottles and stored at -80 ºC awaiting extraction of biochemical components. Caffeine, trigonelline and total chlorogenic acids were extracted and purified using classical methods and analysed using High Pressure Liquid Chromatography (HPLC). For the lipids, the sample was subjected to Soxhlet extraction using n-hexane. The study demonstrated the existence of high variation in biochemical composition among Ruiru 11 sibs. Significant correlations were observed between biochemical and cup quality traits indicating that biochemical composition plays a major role in determining the sensory quality of coffee. The growing environment was also found to have an effect on biochemical composition as portrayed by high locational variations.</p>

The addition of maltodextrin is known to coat flavor components, increase volume, accelerate the drying process, prevent heat damage and increase solubility and characteristic quality of sensory. The general purpose of the research is to know the effect of variation of maltodextrin addition to physical characteristics (white degree, solubility and water absorption), chemistry (water content, ash content, fat content, protein and carbohydrate) and sensory milk quality of instant soybean sprouts based on variation of maltodextrin addition. The method of this research is monofactorial experiment, which consists of 5 treatment of maltodextrin concentration, 0%, 5%, 10%, 15% and 20%. Each treatment was repeated 5 times, so that 25 experimental units were obtained. Physical and chemical test results were analyzed using Anova method followed by Duncan's advanced test while the sensory quality test data were analyzed using Friedman followed by Wilcoxon's advanced test. The results showed that there was a significant effect of the addition of maltodextrin concentration to physical test (white degree, solubility and water absorption) and water content, crude fiber, protein and carbohydrate but no significant effect on ash and fat content. Instant soybean sprouts with a 15-20% maltodextrin variation yield the best physical, chemical and sensory quality.

Abstract Background To explore the optimum fermentation conditions for tobacco leaves and also screen the microbiota and metabolites that are beneficial for fermentation. Methods Tobacco leaves were fermented at 25 °C, 35 °C, and 45 °C for 2, 4, and 6 weeks, respectively. For identification of the best fermentation temperature, physicochemical properties and sensory quality of fermented tobacco were investigated. Subsequently, based on the appropriate temperature, 16 s rRNA sequencing and metabolomics analysis of tobacco were performed to monitor the change of microbes and metabolites during fermentation process (from 2 to 6 weeks). Results Sensory quality analysis indicated that fermentation at 45 °C for 6 weeks represented the optimum condition. Metabolomics analysis showed that a total of 415 metabolites were annotated. The increase of fermentation period led to significant changes of metabolites. Results revealed an increase in concentration of L-phenylalanine and sphingosine as well as decreased concentration of betaine and phytosphingosine with the prolongation of fermentation period (2 to 6 weeks). Distinct changes in the microbiota were also observed with prolongation of the fermentation time. Results revealed that Pseudomonas, Pantoea, and Burkholderia were dominant bacteria in fermentation at 45 °C for 6 weeks. With the extension of the fermentation time, the abundance of Pseudomonas increased, while that of Sphingomonas and Methylobacterium decreased. Furthermore, microbiota profiles were tightly relevant to the altered metabolites, especially compounds involved in the sphingolipid metabolism. Conclusion Suitable fermentation conditions were 45 °C for 6 weeks; phytosphingosine and sphingosine might affect tobacco fermentation via the sphingolipid metabolism pathway. This study provides a theoretical basis for guiding tobacco fermentation and gives insights into reducing harmful substances during tobacco fermentation.

Harvesting and pulping process of coffee cherry in the same day is inaccesible. Storage of coffee cherry before pulping was carried out incorrectly. Some storage treatments before pulping of Arabica coffee cherry had been examined at Indonesian Coffee and Cocoa Research Institute using Arabica coffee cherries from Andungsari Experimental Garden, Bondowoso, East Java. Treatments of the experiment were method and period of cherry storage. Methods of coffee cherry storage were put in plastic sacks; immerse in water, without water replacement; and immerse in water with daily water replacement. Period of coffee cherry storage were 0, 1, 2, 3, 4, 5, 6, and 7 days. After storage treatments, the coffee cherries were pulped, fermented, washed, sundried, and dehulled. The experiment were carried out using randomized block design with three replications. Observation of coffee cherry during storage periods was done on the physical and temperature. Observation of the green coffee were done on the color dan bulk density. The green coffee were roasted at medium roast level for sensory analysis. Observation of roasting profile were out-turn, bulk density and pH of roasted coffee. Sensory analysis used Specialty Coffee Association of America method. Methods and period of cherry storage before pulping significanly influence on the cherry color, parchment color, green coffee color, and the flavor profile of Arabica coffee. Color of dry parchment changed to be red-brown becouse of cherry immersed in water for two days or more. In plastic sacks, Arabica coffee cherry may be stored only for two days, but underwater with or without water replacement, should be not more than five days. Green and sensory quality of Arabica coffee will be deteriorated after five days storage underwater. Coffee cherry storage immerse in water with daily replacing water may improve sensory quality of Arabica coffee.Key word: Arabica coffe, storage, pulping, flavor, physical perqutions

Roasted coffee is subject to loss of quality due to aging, and the intensity of these losses is influenced by packaging. The objective in this study was to evaluate the possible losses in the sensory quality of a specialty roasted coffee, stored in beans for 150 days in different packages and storage temperatures. The experiment was carried out in the Coffee Classification and Industrialization Laboratories of IFSULDEMINAS Campus Muzambinho. The coffee was roasted and after 48 hours it was packed in three different packages and kept stored at room temperature and refrigerated at 18ºC ± 1ºC for 150 days, with evaluations every 50 days, starting from zero time. The experimental design used was entirely randomized with 3 repetitions. Sensory evaluation was performed by three Q-Grader judges, according to the SCAA protocol. The data were evaluated using the SISVAR software, and when significance between treatments was detected, the regression and Scott-Knott tests were applied at the 5% probability level. The packaging used for storage did not interfere in the quality of the coffee. There was an interaction between temperature and storage time for the sensory attribute “body”. The quality decreased linearly with the storage time, from 86 to 80 points, to 84 days of storage.
