This study examined three main possible effects (impact, storage temperature, and duration) that cause and extend the level of bruising and other quality attributes contributing to the deterioration of tomatoes. The impact threshold level required to cause bruising was conducted by subjecting tomato samples to a steel ball with a known mass from different drop heights (20, 40, and 60 cm). The samples were then divided and stored at 10 and 22 °C for 10 days for the further analysis of bruise area and any physiological, chemical, and nutritional changes at two day intervals. Six prediction models were constructed for the bruised area and other quality attribute changes of the tomato. Storage time, bruise area, weight loss, redness, total color change, color index, total soluble solids, and pigments content (lycopene and carotenoids) showed a significant (p < 0.05) increase with the increase of drop height (impact level) and storage temperature. After 10 days of storage, high drop impact and storage at 22 °C generated a higher reduction in firmness, lightness, yellowness, and hue° (color purity). Additionally, regression model findings showed the significant effect of storage duration, storage temperature, and drop height on the measured variables (bruise area, weight loss, firmness, redness, total soluble solids, and lycopene) at a 5% probability level with a determination coefficient (R2) ranging from 0.76 to 0.95. Bruising and other quality attributes could be reduced by reducing the temperature during storage. This study can help tomato transporters, handlers, and suppliers to understand the mechanism of bruising occurrence and how to reduce it.

Storage Disorders

‘Royal Gala’ apples [Malus domestica (Borkh.) Mansf.]can develop postharvest disorders such as flesh browning, senescent breakdown, peeling, cracking, or shriveling during and after cold storage. The objective of this study was to examine the effects of storage temperature and a range (0, 0.25, 0.5, or 1 µL·L−1) of 1-methylcyclopropene (1-MCP) concentrations on fruit quality attributes and incidence and severity of physiological disorders during and after cold storage. Storage temperature differentially affected internal ethylene concentration (IEC), fruit circumference, and cortex color. 1-MCP treatment resulted in significant effects on fruit quality attributes and severity of physiological disorders, regardless of storage temperature. Incidence and severity of diffuse flesh breakdown (DFB), shriveling, cracking, and peeling were highest in control fruit stored but radial stem-end flesh breakdown (RSFB) only primarily in 1-MCP-treated fruit. Incidence of RSFB was highest following storage at 0.5 °C compared with 3 °C. 1-MCP treatment had the most influence on disorder incidence/severity or quality attributes, while treatment concentration of 1-MCP was not significant. Overall, the results indicate that 1-MCP treatment can reduce the incidence of ‘Royal Gala’ DFB but may enhance sensitivity to RSFB, when fruit are stored at 0.5 or 3 °C. Incidence of DFB and RSFB are influenced differentially by storage temperature or by 1-MCP treatment, respectively, indicating they may be different disorders.

‘Durinta’ tomatoes were grown hydroponically using rockwool substrate in greenhouses to assess the seasonal and postharvest changes of selected quality attributes including lycopene and total soluble solids (TSS, % Brix) concentrations in fruit when grown under varied electrical conductivity (EC) in the nutrient solution. Two levels of EC examined in this study were 2.4 and 4.8 dS·m−1 for standard low EC and high EC treatments, respectively. All fruits at light-red and red ripeness stages were harvested and weighed every week, and nine fruits visually representing the median group of red fruits were selected from each EC treatment and subject to measurements of lycopene and TSS concentrations. Of 53 harvest weeks (Dec. 2005 to Dec. 2006), 45 weeks were subject to fruit quality analyses at harvest and 3 weeks were subject to postharvest quality analyses. Lycopene concentration and TSS showed seasonal differences with larger variation in lycopene, but the high EC treatment induced an overall average of 18% greater lycopene concentration and a 20% greater TSS. The regression analyses indicated that efflux solution EC (EEC) was the most influential factor for both lycopene and TSS concentrations, but secondary influential factors were greenhouse temperature for lycopene and daily light integral for TSS. Postharvest storage test showed that selected fruit quality attributes (lycopene, TSS, ascorbic acid, and total phenolics) changed minimally or not at all for 10 days when stored at 12 °C, a widely recommended tomato postharvest storage temperature. Overall, we consider that producing lycopene-rich tomato by controlling EC of nutrient solution was feasible during year-round greenhouse production using a high-wire rockwool culture system.

<p>Kemunduran mutu cabai segar setelah dipanen dipengaruhi oleh faktor lingkungan. Pengemasan dan penyimpanan suhu dingin merupakan bagian dari upaya untuk menekan kemunduran mutu. Tujuan penelitian untuk mengetahui laju rata-rata perubahan atribut mutu dan umur simpan beberapa jenis cabai pada berbagai kemasan dan suhu penyimpanan. Rancangan yang digunakan, yaitu rancangan acak kelompok pola faktorial dengan tiga faktor perlakuan dan tiga ulangan. Faktor pertama, yaitu tiga jenis cabai : (a1) cabai merah besar, (a2) cabai merah keriting, dan (a3) cabai rawit. Faktor kedua, dua suhu penyimpanan (b1) suhu kamar (20±3oC dan (b2) suhu dingin (10±1oC). Faktor ketiga, tiga jenis kemasan, yaitu (c1) baki styrofoam tanpa bungkus, (c2) baki styrofoam dibungkus plastik stretch film, dan (c3) baki styrofoam dibungkus plastik PE 0,03 mm berperforasi. Peubah yang diamati meliputi susut bobot, kadar air, kekerasan, kesegaran, vitamin C, dan umur simpan. Secara umum untuk semua jenis cabai dan jenis pengemas, penyimpanan di suhu dingin dapat menekan laju rata-rata perubahan atribut mutu sekaligus memperpanjang umur simpan sekitar 2,5–3 kali lipat dibandingkan suhu kamar. Pengemasan dengan styrofoam yang dibungkus plastik stretch film (c2) memberikan efek positif terhadap penekanan laju rata-rata perubahan atribut mutu dan umur simpan semua jenis cabai pada penyimpanan di suhu dingin, yaitu masing-masing 25 hari untuk cabai merah besar, 24 hari untuk cabai merah keriting, dan 18 hari untuk cabai rawit. Implikasi dari hasil penelitian ini adalah bahwa penyimpanan di suhu dingin dengan menggunakan pengemasan styrofoam dibungkus plastik stretch film dapat menekan laju rata-rata kemunduran mutu semua jenis cabai.</p><p><strong>Keywords</strong></p><p>Cabai; Mutu; Umur simpan; Suhu; Kemasan</p><p><strong>Abstract</strong></p><p>The deterioration in the quality of fresh chili after harvesting is influenced by environmental factors. Low temperature packaging and storage are part of effective efforts to reduce quality deterioration. The objective of this research was to obtain the rate of quality attribute change and shelf life of several kinds of chili on various packaging and storage temperature. The experiment was conducted using randomized block in a factorial design with three factors and three replications. The first factor was three type of chili: (a1) red hot chili, (a2) curly chili, and (a3) cayenne pepper. The second factor was two types of storage temperature: (b1) room there temperature (20±3°C) and (b2) cold temperature (10±1oC). The third factor was three types of packaging: (c1) styrofoam trays without wrapping, (c2) styrofoam trays with stretch film , and (c3) styrofoam trays with perforated PE plastic 0.03 mm. The variables observed included weight loss, moisture content, hardness, vitamin C, freshness, and shelf life. Generally, for all kinds of chili and types of packaging, storage in cold temperatures can slow the rate of change of the quality attributes while extending shelf life of about 2.5–3 times higher than room temperature. Packing with styrofoam stretch filmed in plastic stretch film (c2) has a positive effect on suppression rate of quality attributes change and shelf life of all kinds of chili on storage at cold temperatures, respectively 25 days for red hot chili, 24 days for curly chili, and 18 days for cayenne pepper. This research implied that storage at low temperatures using styrofoam packaging stretch filmed in plastic stretch film can reduce the rate of decline in the quality of all types of chili.</p>
