ABSTRACT Due to the need to improve the quality and safety of foods, chemical methods used to control grain pests have been replaced by alternative methods. For example, modified atmosphere within the storage units has been used. Therefore, the objective was to evaluate maize grain quality and mortality of insects of the species Sitophilus zeamais and Tribolium castaneum in hermetic and non-hermetic environments for 50 days of storage. The hermetic units consisted of polyethylene "bags" with capacity for 60 kg. A cage with 20 adults of each species and 200 g of maize was placed inside each unit. The oxygen level was quantified every five days. Evaluations of insect mortality and survival occurred at 10, 20, 30, 40 and 50 days of storage. At 0, 30 and 50 days, density, moisture and fungal incidence analyses were conducted. The airtight system is efficient in the control of insects, with satisfactory mortality values for both species. Insects favor the development of fungi during the storage, regardless of the storage system.

Mycotoxins contamination in animal feed is harmful to livestock and leads to residues, such as aflatoxin and its metabolites (aflatoxin M1, aflatoxicol, aflatoxin Q1 and aflatoxin P1) which are deposited in meat, milk, and eggs. The existence of mycotoxins has been widespread; and mycotoxin is the most important contaminant in the food chain because it has implications for human health. Mold growth and mycotoxin production mainly depend on the weather, such as warm temperatures (28-31°C) and high humidity (60-90%). Some types of mold can produce more than one type of mycotoxin and some mycotoxins can be produced by more than one species of fungi. Mycotoxins, especially aflatoxin, fumonisin, zearalenone, ochratoxin, deoxynivalenol, and T2 toxin present in feed and feedstuffs that have to be controlled. Mycotoxins are not only harmful to the health of consumers, but will also reduce the quality of the product that is contaminated, and cause economic losses. The risk of mycotoxin contamination in animal feed could be reduced by inhibiting the mould growth and toxin production, through crop rotation, using proper fungicides, and applying regulation of mycotoxins maximum limit in feed and food in order to prevent any danger to public health.

White and yellow popcorn were stored in different containers at high temperature (35°C) and high relative humidity (85%) conditions for 3 months. Gradual decreases in popping volumes with the lengthening of storage time were observed in both white and yellow popcorn. Internal mold infection was quite low in both white (5.7%) and yellow (3.0%) popcorn at the beginning of storage tests. Few differences were found in total infection levels up to 60 days of storage, except that the Aspergillus glaucus group became established in place of field fungi. A gradual increase in mold infection levels was then observed during the remaining 30 days of storage. Visible mold growth was also observed on the tips of some kernels by the end of storage studies. Internal mold infection in white popcorn stored in an open container was lower (18.3%) than white popcorn stored in a closed plastic bag (75.0%) and closed plastic jar (85.3%), whereas the internal mold infection in yellow popcorn stored in an open container was higher (23.3%) than yellow popcorn stored in a closed plastic bag (6.3%) and closed plastic jar (2.6%). The A. glaucus group were the predominant molds found at the end of storage tests. The ability of toxigenic molds to invade the popcorn was determined using a dry spore inoculum. None of the inoculated molds, which included Aspergillus flavus, Penicillium martensii, and Penicillium viridicatum, were able to invade the popcorn during storage. However, the A. glaucus group predominated at the end of storage tests in the inoculated samples.

Several postharvest technologies are currently being commercialized to help smallholder farmers in sub-Saharan Africa reduce grain storage losses. We carried out a study in Northern Benin to compare the effectiveness of five technologies being sold to protect stored grain. Maize that had been naturally infested by insects was stored in four hermetic storage technologies (SuperGrainbag™, AgroZ® bag, EVAL™, and Purdue Improved Crop Storage-PICS™ bags), an insecticide impregnated bag (ZeroFly®), and a regular polypropylene (PP) woven bag as control. Oxygen levels in hermetic bags fluctuated between 0.5 ± 0.0 (v/v) and 1.0 ± 0.3 (v/v) percent during the seven months of storage. No weight loss or insect damage was observed in grain stored in any of the hermetic storage bags after seven months. However, grain stored in ZeroFly® and PP woven bags had weight losses of 6.3% and 10.3%, respectively. These results will help farmers and development agencies when making decisions to use and/or promote storage technologies to reduce postharvest grain losses.

<p class="p0">Serabi Solo is a traditional food made from rice flour, coconut milk, sugar, salt, water and other ingridients. Serabi is round, flat and porous. Coconut milk was used to develop serabi's taste making it sweet and savory. However, rancidity can decrease quality of serabi during shelf life. Mold growth also affects food safety of this perishable food. Serabi Solo is developing as gift that has longer shelf life beside flavor and appearance variations. Concrete solutions to inhibit rancidity were matcha green tea because of poliphenol as an antioxidant. Matcha green tea addition and pasteurization improved Serabi Solo quality and inhibited rancidity. Based on previous research, matcha green tea 1% made Serabi shelf life longer (24,66 hours). Other solution was coconut milk pretreatment. According to previous research, lemon juice pH 3 was used in coconut milk with hurdle technique made Serabi Solo has shelf life longer (32 hours). Therefore, this activity was to introduce matcha green tea 1% and lemon juice pH 3 to extend shelf of Serabi Solo in SME Linco's Solo.</p><p class="p0"><strong>Bahasa Indonesia Abstrak</strong>: Kue serabi solo merupakan salah satu makanan tradisional yang terbuat dari tepung beras dan santan. Kue ini bulat, pipih dan berpori-pori. Penambahan santan saat memasak serabi membuat serabi terasa manis dan gurih. Namun, santan dalam serabi selain memberikan rasa gurih juga mudah mengalami kerusakan selama penyimpanan. Munculnya aroma dan rasa tengik yang tidak disukai menyebabkan penurunan kualitas dan daya simpan kue serabi. Selain itu, pertumbuhan kapang juga menjadi masalah keamanan pangan pada serabi. Padahal sebagai produk oleh-oleh, serabi diharapkan memiliki umur simpan lebih panjang selain variasi rasa dan tampilan yang menarik dan kekinian. Solusi aplikatif untuk menghambat ketengikan pada kue serabi solo adalah penggunaan matcha green tea karena mengandung polifenol sebagai antioksidan. Penambahan matcha green tea dan perlakuan pasteurisasi pada santan dapat memperbaiki mutu dan mampu menghambat proses ketengikan sehingga dapat memperpanjang umur simpan kue serabi. Hasil dari penelitian sebelumnya, pada uji ketengikan menunjukkan bahwa kue serabi dengan penambahan matcha green tea konsentrasi 1% memiliki umur simpan selama 24,66 jam. Selain penambahan, matcha green tea, upaya memperpanjang umur simpan serabi yaitu dengan mendesain pretreatment santan. Penelitian sebelumnya menggunakan jenis jeruk dan konsentrasi pH asam sitrat yang paling disukai konsumen dan pengaruh serta lama daya simpan serabi dengan pretreatment santan menggunakan teknik hurdle. Serabi yang paling disukai adalah serabi dengan formula pretreatment santan menggunakan air jeruk lemon dengan pH 3 yang memiliki umur simpan 32 jam. Oleh karena itu, pada kegiatan PkM ini mengaplikasikan matcha green tea 1% dan sari jeruk lemon dengan pH 3 untuk meningkatkan umur simpan serabi terhadap variabel ketengikan di UKM Lincos Solo. </p><div id="gtx-trans" style="position: absolute; left: 23px; top: 207.571px;"> </div>
