Fungal Contaminants and Cup Quality of Stored Roasted Arabica Coffee

2024-09-17T06:04:44+00:00

To ensure safe and quality Arabica coffee products for consumption, prevention of microbial contamination during processing has to be guaranteed including appropriate storage practices and determining the ideal storage duration. However, there is a dearth of local information on the quality of roasted Arabica coffee and fungal contaminations as a result of storage. This study analyzed the effect of storage durations on the occurrence of fungal contaminants and its influence on the cup quality of roasted Arabica coffee beans. Wet processed green coffee beans of the Bourbon Red variety were roasted at medium level, packed at 250g in a vacuum metalized polyethylene terephthalate (VMPET) coffee pouches fitted with a one-way valve then stored for 24 months. Results show that after roasting, the coffee beans were free of fungal contaminants but these were detected after 3 months of storage. This implies that contamination could have occurred during the packaging of roasted coffee beans. Five fungal genera were isolated dominated by Penicillium sp., and Cladosporium sp. while fungal genera identified at the species level were Cladosporium cladosporioides and Saccharomyces cerevisiae. Meanwhile, the desirable attributes of the roasted coffee lasted for 5 months of storage. The aroma was the earliest to fade while flavor exhibited slow but gradual waning. Based on these results, it is recommended that roasted Arabica coffee beans be stored using VMPET packaging material for 5 months. Also, processors should conform to Good Manufacturing Practices, specifically hygienic practices during handling and packing of roasted coffee to prevent fungal contamination. Finally, the best-before date or date of roasting should be indicated on the packaging labels of roasted coffee products.

Verification on Energy Digestibility in Ground Yellow Corn, Rice Bran, and Copra Expeller Fed to 10kg to 15kg Benguet Native Pigs

2024-09-17T06:04:46+00:00

Digestible and metabolizable energy contents of feed ingredients are important in swine nutrition as they directly influence feed utilization efficiency and growth performance. By accurately measuring these parameters, producers can formulate diets tailored to pigs' energy needs at various growth stages, leading to improved feed efficiency, reduced costs, and minimized environmental impacts. In this study, a digestibility trial was carried out to determine the digestible energy (DE) and metabolizable energy (ME) in ground yellow corn, rice bran, and copra expeller fed to Benguet native pigs with body weights ranging from 10kg to 15kg (102 to 127 days old) to confirm digestibility values obtained from a previous study. The total fecal collection method following the marker-to-marker approach was employed using chromic oxide as a marker to indicate the start and end of fecal collection. Ground yellow corn had 3,669 DE and 3,522 ME kcal/kg with an apparent total tract digestibility (ATTD) of 90.17%, whereas, rice bran had 4,364 DE and 4,189 ME kcal/kg with an ATTD of 84.14%. Copra expeller had 4,921 DE and 4,724 ME kcal/kg with an ATTD of 80.78%. The DE and ME values for ground yellow corn and rice bran are close to the values obtained in the previous study verified; however, values for copra expeller are different. These results are important in the establishment of feeding standards for Benguet native pigs weighing 10kg to 15kg.

2024-09-17T06:04:50+00:00

Alumni feedback has emerged as one of the central pillars of the quality process due to the valuable insights from the alumni in evaluating the academic programs and services of higher education institutions. This study determined the Bachelor of Secondary Education (BSED) alumni’s retrospective evaluation of their undergraduate teacher training as to the adequacy and relevance of acquired 21st-century skills. It also sought their satisfaction and recommendations for curricular and service improvements. A survey procedure was used to collect data from 602 BSED graduates from a Philippine State University from 2013 to 2017. Results indicate that overall, the traced BSED alumni were highly satisfied with the pre-service training – both in terms of curriculum and services offered. The 21st century skills they acquired were claimed to be highly relevant to their current jobs. They, however, call for greater exposure with authentic pedagogical preparations and research, and for improved facilities. Moreover, they recommended a regular curriculum review to check on the courses’ relevance, arrangement, and “balance”. Meanwhile, variety, relevance, and practicality were among the discipline-specific recommendations forwarded. In conclusion, the satisfaction of the alumni with their undergraduate training was evident, but there are areas of improvement that the institution must consider.
