Abstract

Pineapple chips have low moisture content and water activity, so they are able to absorb water from the environment and have an impact on shorter shelf life.  One way to reduce the absorption of moisture is by choosing to package with good barrier properties. This study conducted experimentally to estimate the shelf life of household products of pineapple chips with aluminum foil and polypropylene packaging using the water sorption isotherm (ISA) curve approach. Some models of the ISA curve equation were tried, including GAB, Hasley, Caurie, Chen Clayton, Oswin, and Henderson. The parameters observed in this study consisted of initial, critical, and equilibrium moisture content, determination of the water sorption isotherm curve, slope value, saturated vapor pressure, packaging permeability, packaging area, dry weight per package, and calculation of shelf life. The results showed that the selected ISA curve equation model for pineapple chips was the Hasley model with the equation Log [In 1/aw)] = Log -1.73 + Log 1.42 Me. Permeability of polypropylene packaging was obtained at 0.1275 (g/m2.hari.mmHg), while aluminum foil was 0.0441 (g/m2.hari.mmHg). Therefore, pineapple chips have a shorter shelf life with polypropylene packaging compared to aluminum foil. The shelf life of pineapple chips with polypropylene packaging at RH 70-90% was 31.5-46.5 days, while aluminum foil packaging at RH 70-90% was 87.3-129.3 days with a critical water content of 0.0674 g H2O/g of the material. The use of aluminum foil packaging extended 2-3 times the shelf life of pineapple chips to increase the added value of the household industry of pineapple chips

Abstract

Fried sago crackers are dry local foods easily damaged by moisture during storage. To increase economic value and open commercialization opportunities, a study aimed to estimate the shelf life of white and red fried sago crackers using an acceleration method based on the water sorption isotherm curve. Estimating the shelf life was carried out by storing crackers in several modified jars containing different saturated salt solutions. Calculating the moisture permeability constant of polyethylene and polypropylene packaging was also carried out to support the necessary data. The results showed that sago crackers packaged in polypropylene had a longer shelf life than polyethylene plastic. The white sago crackers with polypropylene plastic had a shelf life of 19.89-69.83 days at 70-90% RH, while polyethylene was 12.02-42.21 days at 70-90% RH with 0.0434 g H2O.g solid-1 critical water content. The red sago crackers with polypropylene plastic had a shelf life of 18.26-69.93 days at 70-90% RH, while polyethylene was 11.04-42.27 days at 70-90% RH with a critical water content of 0.0455 g H2O.g solid-1. The chosen model for the water sorption isotherm curve was Hasley and GAB, with equation log (ln (1/aw)=-1.82-1.31 log Me for white sago fried crackers and Me=(0.5157aw)/(1-0.9632aw)(1+15.578aw) for red sago fried crackers, respectively. Fried sago crackers in polypropylene plastic packaging have the potential to be developed as local food products with a longer shelf life.

Abstract

Pineapple sheet jam products can provide value to pineapple fruit. This study aims to determine the concentration of porang flour as a stabilising agent in terms of physicochemical properties in making sheet jam. The research was conducted experimentally using a completely randomised design (CRD) with four treatments and four replications, resulting in 16 experimental units. The treatment was the addition of flour, namely TP1 (0.25g porang flour), TP2 (0.50g porang flour), TP3 (0.75g porang flour), and TP4 (1.00g porang flour). The parameters observed included moisture content, ash content, syneresis test, total soluble solids (TPT), crude fibre content, and sensory assessment consisting of descriptive test and hedonic test including colour, aroma, taste, elasticity, and overall assessment of jam sheets. The treatment chosen in this study was the TP3 treatment with 0.75g flour addition which had characteristics of 17.17% moisture content, 0.30% ash content, day 2, 3, and 4 syneresis test of 1.89%, 3.42%, and 4.28% respectively, total soluble solids (TPT) of 22.10°Brix, and crude fibre content of 0.05%.

Abstract

Food additives are compounds that are deliberately added to food in certain quantities and sizes and are involved in processing, packaging and/or storage. Food additives are mixed ingredients that are not part of the food raw materials, but are added to food to influence the nature or shape of the food, including colorings, preservatives, flavorings, anti-caking agents, whiteners and thickeners. Most people use food additives without clear measurements, which will have negative consequences for people's health. Therefore, outreach activities are needed to the public regarding the proper and correct use of food additives. The aim of this service activity is to provide information about food additives to the community, especially the community in Pagaruyung village, Tapung District, Kampar Regency. With these service activities and publications, it will help disseminate information regarding the correct use of food additives. Before public outreach, a pre-test was given, where the level of public understanding regarding BTP was 60%. After presenting the BTP material, a post test was carried out where public understanding increased to 92%. For evaluation of the implementation of community service activities, almost all people felt the benefits and were very satisfied with the activities carried out.

Abstract

Rambut jagung merupakan bagian dari tanaman jagung yang belum dimanfaatkan secara optimal. Bentuknya menyerupai benang atau rambut dengan warna kekuningan. Rambut jagung mengandung senyawa aktif seperti flavonoid, saponin, dan tanin yang bermanfaat untuk kesehatan, terutama dalam pengelolaan tekanan darah dan fungsi ginjal. Salah satu pemanfaatan limbah rambut jagung adalah dengan mengolahnya menjadi teh herbal. Tujuan dari kegiatan ini adalah untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam memanfaatkan limbah rambut jagung sebagai bahan baku pembuatan teh herbal. Kegiatan ini dilakukan melalui beberapa tahapan, yaitu sosialisasi manfaat rambut jagung, demonstrasi pengolahan rambut jagung menjadi teh herbal, dan pelatihan pembuatan serta pengemasan produk teh herbal. Metode yang digunakan mencakup ceramah, diskusi, dan praktik langsung agar masyarakat dapat memahami dan mengaplikasikan teknik produksi teh herbal ini secara mandiri. Melalui kegiatan ini, diharapkan masyarakat dapat mengoptimalkan pemanfaatan rambut jagung, meningkatkan nilai ekonomi produk yang dihasilkan, serta meningkatkan kesadaran lingkungan dengan mengurangi limbah pertanian. Hasil kegiatan ini menunjukkan bahwa peserta mampu memproduksi teh herbal dari rambut jagung dengan baik dan tertarik untuk mengembangkan produk ini sebagai usaha sampingan.

Abstract

This research aims to obtain the best addition of red ginger extract in corn starch edible coating to extend the shelf life of tomatoes. This research method used an experimental method, obtaining 15 experimental units by using a fully randomized design (CRD) with five treatments and three replications. The treatments used include P0 (without addition of red ginger extract), P1 (1% addition of red ginger extract), P2 (3% addition of red ginger extract), P3 (5% addition of red ginger extract), and P4 (7% addition of red ginger extract) in edible coating of corn starch with addition red ginger extract to extend shelf life tomatoes and stored for 21 days. The results showed that the addition of red ginger extract affected weight loss, hardness, total dissolved solids, pH, vitamin C and total microbes. Data were analyzed statistically using analysis of variance (ANOVA) and continued with DMRT at 5% level. The best treatment of this research was P4 with a 14.71% weight loss value, 5.58 kgf hardness, 1.413Brix total dissolved solids, 4.92 pH, 27.41 mg/100g vitamin C and 4.46 log CFU/g total microbes.
