Therefore, this research aimed to explore the optimal parameters for foaming and drying through the foam-mat drying method, intending to achieve superior foam properties and convert pasta sauce into powdered form. The Central Composite Design methodology was employed to ascertain the influence of four independent variables, namely egg white concentration, CMC concentration, water-to-pasta sauce ratio, and whipping time, on the properties of the foam. The drying conditions were orchestrated using a completely randomized design with a single factor comprising three levels, denoting drying temperatures of 50, 60, and 70 °C. The results showed that heightened egg white concentration, water-to-sauce ratio, and whipping time correlated positively with expansion volume and inversely affected foam density as well as drainage volume. Meanwhile, elevated CMC concentration exhibited a diminishing impact on expansion volume with increase in foam density and drainage volume. The optimized conditions conducive to the generation of superior foam properties were 8.99% egg white concentration, 0.1% CMC concentration, 0.54:1 ratio of water to pasta sauce, and 5 minutes of whipping time. The higher drying temperature resulted in lower moisture content, , WAI (water absorption index), and hygroscopicity of pasta sauce powder, with an increase in WSI (water solubility index) and color (lightness). The most favorable drying temperature was determined to be 60 °C, which led to a pasta sauce powder of 7.67% moisture content, 0.21, WAI 8.55 g/g, WSI 0.53%, hygroscopicity 5.65% and color (L 57.21, a 13.83, and b 16.01).","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136343200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teknik budidaya ini menggunakan air sebagai media tanam dan efektif pada lahan terbatas. Meskipun hidroponik meminimalkan perawatan yang dibutuhkan tanaman, pemantauan rutin terhadap larutan nutrisi tetap penting. Tujuan dari penelitian ini adalah untuk mengembangkan sistem pemantauan dan pengendalian larutan nutrisi hidroponik DFT berbasis Internet of Things (IoT) pada kangkung. Sistem kendali yang digunakan adalah sensor pH sebagai pendeteksi nilai pH larutan, Arduino Uno sebagai mikrokontroler, modul ESP 8266 sebagai modul wifi, dan aplikasi Blynk sebagai platform IoT dan kontrol PID. Hasil kalibrasi sensor pH dengan membandingkan nilai sensor pH dengan pH meter pada larutan buffer memberikan nilai R 2 sebesar 0,9997, sedangkan nilai sensor pH selama 18 hari memberikan nilai R 2 sebesar 0,9908 dengan hasil error sebesar 0,274%. Hasil penelitian menunjukkan bahwa sensor pH bekerja dengan baik dan akurat. Pengontrol PID sistem ini adalah Kp=2. 1; Ki = 0,05; dan Kd = 0,03. Pemeriksaan kondisi pabrik di 60 tanaman (30 kangkung dengan sistem kendali dan 30 kangkung tanpa sistem kendali).

After 8 days of incubation in the refrigerator, the color change was recorded and analyzed using ImageJ, while free fatty acid contents were determined by titration. The results showed that 15% KCE and 15% CCE exhibited higher antioxidant activities than 0.1% BHT. There was no significant difference in the L (lightness) and b (yellowness) values between the treatments, but variations were evident in the a (redness) values. FFA values were significantly different between treatments, with untreated control registering the highest value at 0.41%, and the KCE 15% and CCE 15% concentrations showing the lowest values at 0.12%.

To address this, post-harvest processing techniques, such as applying edible coating, are employed. This coating forms a thin plastic-like layer on the surface of the product, inhibiting metabolism while ensuring safety for consumption. Therefore, this research aimed to assess the effect of edible coating comprised of salacca seed flour and glucomannan, both at room temperature and under cold storage conditions, on weight loss, hardness, and color, ultimately extending the shelf life of chili. Edible coating procedure involved using salacca sourced from the Sleman market, porang tuber from Gunung Kidul farmer, as well as aqua dest, glycerol, and 96% ethanol. Various concentrations of coating layers were tested, including 1% salacca seed flour, 5% salacca seed flour, 10% salacca seed flour, 0.4% glucomannan, and a non-coated control group. The result showed that the optimal treatment during storage at room and the cold temperature was achieved with a 0.4% glucomannan coating layer and 1% salacca seed flour coating layer. Based on evaluations of weight loss, hardness, and color, it could be concluded that both salacca seed flour and glucomannan can extend the shelf life of chili.","PeriodicalId":7563,"journal":{"name":"agriTECH","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136343053","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study aimed to determine the effect of varying extraction times on the color and antioxidant quality of Sargassum duplicatum extract. One of the methods used to extract Sargassum duplicatum is ultrasonication, which involves using ultrasonic waves to break down the cell walls of the material and facilitate efficient compound extraction. The extraction was carried out at 15 (A), 30 (B), and 45 minutes (C), with three repetitions for each treatment. The assessed parameters included yield calculation, total carotenoids, antioxidant activity, and color intensity. Parametric data were analyzed using ANOVA and Tukey HSD follow-up tests. The extraction process used an 80% ethanol solvent at 40 °C and a frequency of 42 kHz. This study employed an experimental laboratory approach using a completely randomized design (CRD) with different extraction times. The results showed significant differences (p<5%) in yield value, total carotenoids, antioxidant activity, and color intensity of Sargassum duplicatum extract at different extraction times.
