<p>Red-bell peppers (<em>Capsicum annuum var. Athena</em>) is a perishable vegetable, so it is necessary to improve its shelf life. The edible coating technology can potentially be used to increase shelf life and improve microbiological quality of paprika. This study aimed to determine the effect of sago starch-based coating material with incorporation of natural antimicrobial lemongrass oil on the characteristics of red-bell pepper during storage at 20 and 8°C. The study included preparation of sago starch-based coating material with the addition of lemongrass oil as antimicrobial, their application on red-bell pepper and analysis of physical properties as well as the total microbial during storage. The research design used was factorial completely randomized design consisting of two factors (concentration of lemongrassoil as an antimicrobial and dipping time) with three replications. The results showed that the best treatment was dipping of red-bell peppers into coating formula containing lemongrass oil 0.2% for 5 minutes and storing at 8°C. This treatment provided enhancement of red-bell pepper shelf life up to 7 days with the acceptable total microbials and quite fresh conditions.</p><p> </p><p><strong>APLIKASI BAHAN PENYALUT BERBASIS PATI SAGU DAN ANTIMIKROBA MINYAK SEREH UNTUK MENINGKATKAN UMUR SIMPAN PAPRIKA (<em>Capsicum Annum Var.

Bell pepper is one among fruit vegetables that had good market prospect both for local trade and export. Nevertheless,  the commodity has perishable properties thus it needs good post harvest handling that could increase its shelf life. One of among other technologies, surface coating (by edible coating) of bell pepper is potential to be applied. Thistechnology might be added by natural antimicrobes to avoid microorganism attack during storage time, so its shelf life might be extended. The objective of this research was to evaluate consumer’s acceptability and vitamin C content on red bell pepper which were applied by edible coating based on sago starch and lemongrass oil that acting asnatural antimicrobes. Treatment given for testing its sensory properties were: (a) concentration of lemongrass oil (0.2% and 0.4%) and (b) dipping time in edible coating formula; 3 and 5 minutes. Red bell pepper wasthen stored at cold room temperature (8 °C). As control treatment, the inspection was also applied on non-coated red bell pepper and coated red bell pepper without addition of lemongrass oil. Result showed that coating treatment did not affect consumer’s acceptability on aroma, texture, taste and overall acceptability. Coating treatment only affected consumer’sacceptability on color of red bell pepper. Panelists could accept coating treatment on red bell pepper with or without  addition of lemongrass oil as antimicrobes. Moreover, red bell pepper treated by 0.4% lemongrass oil storaged at 8°C  was still had high vitamin C content (1.5 mg/100 g) on 27 days storage.Keywords: Red bell pepper, edible coating, consumer’s acceptability, vitamin C ABSTRAKPaprika merupakan salah satu jenis sayuran buah yang memiliki prospek pasar yang cerah dan terbuka lebar baik untuk pasar domestik maupun ekspor. Namun, paprika merupakan sayuran buah yang tidak awet dan mudah rusak (perishable commodity) sehingga paprika memerlukan penanganan pascapanen yang tepat agar dapat meningkatkanmasa simpannya. Salah satu teknologi potensial untuk diterapkan pada paprika yaitu pelapisan permukaan paprika dengan bahan edible (dapat dimakan) dan ditambah dengan antimikroba alami untuk menghindari serangan mikroba. Penelitian ini bertujuan untuk mengetahui pengaruh konsentrasi minyak sereh dan lama perendaman terhadap sifatkimia dan organoleptik (warna, aroma, tekstur dan rasa) paprika merah yang diberi perlakuan edible coating berbasis pati sagu dan antimikroba alami minyak sereh. Selain itu juga dianalisis perubahan mutu kimia vitamin C pada paprika merah selama penyimpanan. Perlakuan yang diberikan untuk pengujian karakteristik sensori yaitu (a) konsentrasiminyak sereh 0,2% dan 0,4% dan (b) lama pencelupan dalam formula edible coating yaitu 3 dan 5 menit. Paprika lalu disimpan pada suhu 8°C. Sebagai kontrol dilakukan juga pengamatan terhadap paprika yang tidak di coating dan yang di coating namun tanpa menambahkan minyak sereh. Hasil penelitian menunjukkan bahwa perlakuan coating tidak berpengaruh nyata pada penerimaan panelis terhadap atribut aroma, tekstur, rasa maupun penerimaan keseluruhan paprika. Perlakuan coating hanya berpengaruh nyata pada penerimaan panelis terhadap atribut warna paprika merah. Panelis dapat menerima perlakuan coating pada paprika, baik dengan atau tanpa penambahan antimikroba. Kandunganvitamin C pada paprika dengan perlakuan 0,4% minyak sereh pada suhu 8°C pada hari penyimpanan ke-27 masih tetap tinggi yaitu 1,5 mg/100g.Kata kunci: Paprika, edible coating, preferensi konsumen, vitamin C

Temperature Storage

To study ripening-related chilling injury (CI) of bell pepper (Capsicum annuum L.), fruit at mature green, breaker, and red-ripe stages were stored at 1, 5, 7, and 10 °C for 4 weeks. Surface pitting was evaluated after storage at 1 °C for 2 weeks followed by a 2-day exposure to room temperature (20 °C). Exposing fruit to 1 °C enhanced water loss, respiration, ethylene production, and electrolyte leakage, but slowed color change. Weight loss, respiration, ethylene production, electrolyte leakage, and color change increased more in breaker than in mature green and red-ripe fruit. No pitting symptom was observed at temperatures of 5 to 10 °C. After storing peppers at 1 °C for 2 weeks, breaker stage fruit exhibited chilling symptoms of severe surface pitting with more sheet pitting and deeper peel depression. Mature green fruit showed only moderate pitting. However, red-ripe peppers showed no injury and cells showed a normal appearance after low-temperature storage (1 °C). These results show that bell peppers tended to be more susceptible to chilling temperature while at the breaker stage and that the increase in visible CI is correlated with increased water loss, respiration, ethylene production, electrolyte leakage, and color change during storage.

Studies were conducted to examine the effects of pruning treatments applied to spring-transplanted bell peppers (Capsicum annuum L.) on marketable fruit yield in late summer and fall. Control plants were set in the field in early May 1997 (Oklahoma) and Apr. 1998 (Oklahoma and Texas) and were harvested weekly into October (Oklahoma) or periodically into December (Texas). In 1997, there were no differences in total marketable fruit weight among four treatments involving height and method of pruning, but all reduced total marketable fruit weight relative to the control. In Oklahoma in 1998, the control was compared to plants mowed on 27 July at an average height of ≈24 cm. Mowed plants produced less total marketable fruit weight but more U.S. Fancy fruit than control plants. Also, control and mowed plants did not differ in weight of U.S. no. 1 fruit. In Texas in 1998, the control was compared to plants mowed on 4 Sept. at a height of ≈20 cm. Mowed plants produced more than double the weight of U.S. no. 1 fruit and fewer cull fruit than control plants. Nonpruned transplants set in the field in Summer 1998 (Oklahoma and Texas) gave low marketable yields. Maintaining spring-transplanted bell peppers is a viable technique for fall pepper production, and the highest total marketable yields may occur if these plants are not mowed. However, mowing offers an opportunity for increased fall production of premium fruit, and mowed plants would be easier to manage than unpruned plants.

Blossom End Rot

Bell peppers (Capsicum annuum L.) are ranked eighth in value for vegetable production in the United States (USDA-NASS, 2019). Due to the high value of bell peppers, disorders such as blossom-end rot (BER) can cause significant losses in yield by up to 35% for growers. BER is the symptom of a calcium (Ca2+) deficiency that may occur during periods of cell expansion when the supply of Ca2+ may be lower than demand. In this study, we determined the temporal patterns of the fruit Ca2+concentration ([Ca2+]) and accumulation in three separate studies under field and greenhouse conditions. In the three experiments, [Ca2+] during fruit development showed varied patterns: it remained constant, decreased transiently during the cell expansion phase, or displayed a more gradual sustained decrease. However, in the three experiments, fruit Ca2+ accumulation increased during development as fruit size increased. In two experiments, the distal part of the fruit had lower [Ca2+] than the proximal end. However, there was no correlation between [Ca2+] in various fruit sections with BER incidence. Seeds and placental tissue had increased [Ca2+] and several other macro- and micronutrients; this spatial distribution of Ca2+ coupled with subcellular Ca2+ distribution should be explored in future studies. The temporal pattern of Ca2+ accumulation in this study suggests that fruit Ca2+ uptake continues throughout fruit development. Therefore, Ca2+ application during bloom and early fruit development may prevent or minimize Ca2+ deficiency disorders in bell pepper.

The effect of preharvest calcium sprays on postharvest quality of sweet bell peppers grown in plasticulture was studied. Calcium was applied as three sprays of 0.4% (wt/vol) CaCl2 in water to plots of Oriole and Bell Boy peppers in each of 2 yr. Fruit weight, water loss, firmness, decay and the composition of the pectic fractions were determined at harvest and during storage. Preharvest sprays of CaCl2 increased the weight of fruit for Oriole, improved firmness retention in storage, decreased decay, increased pericarp wall thickness and the insoluble pectic fractions of both cultivars but had no effect on water loss in storage. The results suggest that Ca improves firmness retention through enhancing the pectic composition of cell walls and pericarp wall thickness. Effects of Ca sprays on reducing decay could not be attributed to factors measured in this work. Preharvest foliar sprays of CaCl2 show promise in reducing postharvest decay and improving firmness retention in sweet bell peppers grown under plasticulture. Key words: Capsicum annuum L., calcium, pectin, shelf life, postharvest decay
