Color and Organoleptic Changes of the Golek Mango Fruit (Mangifera indica L.) On Zero Energy Cool Chamber (ZECC) Storage Method with Packaging Combination

The increase in the amount of mango fruit production is due to their high nutritional content affordable, and relatively easy to find. However, like other horticultural crops, Mango can be easily bruised or damaged. The fruit damage can be caused by improper post-harvest handling, causing mango quality and has a short shelf life. The study aimed to determine the shelf life and quality of mango Golek stored in Zero Energy Cool Chamber (ZECC) using LDPE packaging and LDPE packaging with additional perforations. The first stage was observing the physical quality of the fruit and then post-harvest treatment such as washing, packaging and storing mangoes at ZECC temperature (±26°C). The second stage was the mango quality test after storage. Tests in the form of skin color and organoleptic. The results obtained in this study were mangoes packed with LDPE and LDPE with perforations. Mango packaged in LDPE packaging were able to retain L* color, b* color, organoleptic color, aroma, texture and taste. Mangoes packed with perforated LDPE packaging can retail, L * color, b * color, organoleptic color, aroma, texture and taste

Zero-Energy Cool Chamber in Anthracnose Disease Management of Postharvest Capsicum frutescens

Anthracnose caused by Colletotrichum gloeosporioides is one of important diseases causing postharvest losses on chili. This study aimed to determine the effectiveness of the zero energy cool chamber (ZECC) in reducing the severity of anthracnose in Capsicum frutescens L. and extending the shelf life of chilies. The research was started by designing and building ZECC as a storage area for chilies. Chilies with and without fungal inoculation were stored in ZECC and storage chamber at room temperature. C. gloeosporioides experienced a growth inhibition of 40.48% after being stored in ZECC compared to its growth at room temperature. Storage of chilies in ZECC was able to reduce the severity of anthracnose by 56.2% on the 15th day, did not affect vitamin C content and total dissolved solids (TSS) and was able to reduce chilies weight loss during storage. Based on the organovisual test using the visual quality rating method and the Hedonic sensory test, consumers prefer chilies stored in the ZECC. The results showed that storage in ZECC could extend the shelf life of chilies. This storage model does not use electricity or is zero energy so it can be used by small scale farmers. This is the first report on the use of ZECC for the management of anthracnose in postharvest chilies in Indonesia.

Reduction of Shiga toxin-producing Escherichia coli in a beef abattoir

The aim of this work was to reinforce actions tending to reduce Shiga toxin-producing Escherichia coli (STEC) in beef products from an Argentinean commercial abattoir implementing Hazard Analysis and Critical Control Point (HACCP) practices. An environmental stx map was built with 421 environmental samples from the slaughter, quartering, cool chamber and deboning sectors (February-May 2013). For stx determination, 125 carcass and 572 anatomical cut samples were used. Based on the environmental stx mapping results, improvement actions were designed and implemented (June and July 2013). After implementing improvement actions, 160 carcass and 477 anatomical cut samples were collected to identify stx and verify the impact of improvement actions (August-December 2013). Our results showed stx-positivity in pre-operational (10.1%) and operational (15.5%) environmental samples and in carcass and beef cut samples before (4.8 and 10.1%; p = 0.144) and after (1.2 and 4.8%; p = 0.0448) implementing improvement actions, respectively. Although improvement actions reduced stx in beef cuts, it is difficult to implement and sustain a system based on stx zero-tolerance only by reinforcing Good Manufacturing Practices, Sanitation Standard Operating Procedures and HACCP practices. The application of combined intervention strategies to reduce STEC in carcasses and beef cuts should be therefore considered.

Effect of postharvest edible coatings on fruit quality of guava cv. Sufaid Gola under ambient and zero-energy cool Chamber storage conditions

Investigations were made to evaluate the effect of different edible and chemical coatings on quality and shelf life of guava (Psidium guajava L.) cv. Sufaid Gola fruits stored under ambient (20 ± 3 °C) and zero energy cool chamber (ZECC) conditions (15 ± 3 °C). The fruits were subjected to different coating treatments, i.e., control (uncoated fruits, T0), fruits coated with 1% CaCl2 (T1), 2% CaCl2 (T2), 10% Aloe vera gel (T3) and 15% Aloe vera gel + 1.5% Ascorbic acid (T4). The studied quality attributes included weight loss, total soluble solids (TSS), pH of fruit juice and fruit skin colour. As the storage period increased, weight loss, juice TSS and pH values significantly increased. Fruit skin colour also changed depending on the coating treatment, storage conditions and duration. Fruits stored at ZECC conditions had lower weight loss with lesser juice TSS and pH values and resulted in prolonged shelf life than ambient storage conditions. The fruits coated with 15% Aloe vera gel + 1.5% Ascorbic acid and 10% Aloe vera gel resulted in lower weight loss as compared to other treatments. Fruit coated with 15% Aloe vera gel + 1.5% Ascorbic acid and 2% CaCl2 had better shelf life with lower juice TSS and pH values as compared to other treatment combinations.

Quality and Storability of Mango During Zero Energy Cool Chamber (ZECC)

Many researchhavefound thatthe use of zero energy coolchamber (ZECC) extend the shelf life of stored fruits and vegetables. There is a lack of study conducted in Indonesia about the use of ZECC to keep mangos after harvesting though. The present study, therefore, was aimed to understand the quality and storability of stored mangos in ZECC. Three different storage containers, a ZECC, ambient, and refrigerator with different average RH and temperature, were used to place selected ripe mangos (Mangifera indica L) that were manually harvested from farmers’ field nearby. The ZECC was set up at the residential complex for lecturer of Hasanuddin University as the experiment site. Results showed that mangos inside ZECC were acceptable until eleven days of storage after considering both quality and sensory evaluation. The result suggests that ZECC can maintain mango’s quality and extend its shelf life, which reveals that ZECC seems promisingfor commercial application
