Organoleptic Score

The storage method is one way to maintain coffee quality. Storage with aluminum foil and plastic (PP) packaging is an effective and safe technology to protect coffee grounds. Specialty coffee powder cannot be accepted if the organoleptic score is below 80, for that it is necessary to estimate the shelf life. This study aims to analyze the quality degradation of Bondowoso arabica coffee powder based on specialty standards using the SCAA protocol during storage with aluminum foil packaging and compare it with plastic packaging (PP) and estimated the shelf life of Bondowoso arabica ground coffee products based on flavor value parameters using the arrhenius method. Coffee powder quality degradation with plastic packaging (PP) is faster than aluminum foil packaging. This is because plastic packaging on the fourth day with a temperature of 40°C is not meet specialty standards. The greater the temperature used, the greater the decrease in quality. The shelf life of coffee powder uses aluminum foil packaging, which is 3 days at 40°C, 2 days at 50°C, and 1.3 days at 60°C. Whereas with plastic packaging (PP), the shelf life is shorter, which is 2 days at 40°C, 1.2 days at 50°C and 1 day at 60°C. Keyword: accelerated Shelf-Life Testing (ASLT), aluminum foil, arabica coffee, packaging, shelf

A novel active bio-based pressure-sensitive adhesive incorporating cinnamon oil (Bio-PSA/CO) obtained from the mixture of natural rubber (NR), xyloglucan (XG), and cinnamon oil (CO) for food antimicrobial applications were successfully developed by using a two-roll mill mixer. The effect of the main process factors (i.e., nip gap and mastication time) and XG content on the adhesion properties of the obtained PSA were investigated with different coated substrates including kraft paper, nylon film, polypropylene (PP) film, and aluminum foil (Al). The results suggested that the developed NR-PSA/CO could be applied well to all types of substrate materials. Peel strength and shear strength of the NR-PSA/CO with all substrate types were in the ranges of ~0.03 × 102–5.64 × 102 N/m and ~0.24 × 104–9.50 × 104 N/m2, respectively. The proper processed condition of the NR-PSA/CO was represented with a nip gap of 2 mm and a mastication time of 15 min. An increase in XG content up to 40–60 phr can improve the adhesion properties of the adhesive. The resulting material could be used as an active sticky patch to extend the shelf-life of food in a closed packaging system. The shelf-life of the food samples (banana cupcake) could be extended from 4 to 9 days with NR-PSA/CO patch.

This paper reports on the chemical compounds in arabica coffee beans with a high Specialty Coffee Association (SCA) cupping score, especially those in specialty coffee beans. We investigated the relationship between the chemical compounds and cupping scores by considering 16 types of Coffea arabica (arabica coffee) beans from Guatemala (SCA cupping score of 76.5–89.0 points). Non-targeted gas chromatography-mass spectrometry-based chemometric profiling indicated that specialty beans with a high cupping score contained considerable amounts of methyl-esterified compounds (MECs), including 3-methylbutanoic acid methyl ester (3-MBM), and other fatty acid methyl esters. The effect of MECs on flavor quality was verified by spiking the coffee brew with 3-MBM, which was the top-ranked component, as obtained through a regression model associated with cupping scores. Notably, 3-MBM was responsible for the fresh-fruity aroma and cleanness of the coffee brew. Although cleanness is a significant factor for specialty beans, the identification of compounds that contribute to cleanness has not been reported in previous research. The chemometric profiling approach coupled with spiking test validation will improve the identification and characterization of 3-MBM commonly found in arabica specialty beans. Therefore, 3-MBM, either alone or together with MECs, can be used as a marker in coffee production.

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.
