Abstract

Fruit jam added with probiotics is an innovation in food product development. In this research, pineapple jam was made not only to increase the economic value of the pineapple but also to add the health properties due to the addition of probiotics (Lactobacillus acidophilus). The objective of the study was to evaluate the stability of L. acidophilus microcapsules ATCC 314 against heating and storage in low sugar pineapple jam. L. acidophilus was microencapsulated with emulsification method using sodium alginate and oil with Tween 80 as the emulsifier. The microcapsules size was 40-60 µm. Microencapsula-tion was found to improve the stability of L. acidophilus upon heat processing. Total healthy cells of the microencapsulated probiotics heated at 40 and 50°C (1.4x107 CFU/mL; 6.9x106 CFU/mL) were higher than the free probiotic cells (7.9x106 CFU/mL; 4.5x106 CFU/mL). The stability of the encapsulated probiotics in pineapple jam at 4°C (14 days of storage) was also better than that of the free cells. Conclusively, micro-encapsulation process with alginate could increase probiotic stability, thus can be considered in probiotic pineapple jam development.

Abstract

Alga cokelat mengandung pigmen karotenoid yang didominasi oleh fukosantin dengan aktivitas antioksidan yang tinggi. Karotenoid dari alga cokelat, termasuk fukosantin, belum sepenuhnya dimanfaatkan dalam formulasi pangan karena sifatnya yang kurang stabil. Karotenoid yang akan diaplikasikan dalam produk pangan perlu ditambah dengan bahan penstabil. Penelitian ini bertujuan untuk menganalisa kestabilan ekstrak alga cokelat dengan penambahan gula kelapa dan lemak kakao yang diformulasikan dalam bentuk foodbars, menguji aktivitas antioksidan, proksimat, tekstur, dan daya simpan produk foodbars yang mengandung fukosantin. Alga cokelat dari Pulau Sumbawa diekstrak menggunakan etanol 96% untuk memperoleh kandungan fukosantin. Analisa fukosantin dilakukan menggunakan high performance liquid chromatography (HPLC) dengan detektor diode array SPD-M20A (Shimadzu). Aktivitas antioksidan ekstrak alga cokelat dan selurruh bahan penyusun foodbars diuji aktivitas antioksidannya menggunakan metode DPPH (2,2-difenil-1-pikrilhidrazil) dan ekstrak alga cokelat menunjukkan aktivitas tertinggi. Foodbars formula 2 paling disukai oleh panelis semi terlatih melalui uji organoleptik. Selain itu, formulasi foodbars memiliki tingkat kekerasan tidak berbeda secara signifikan dengan produk komersial. Hasil uji daya simpan menunjukkan pertumbuhan mikroba yang rendah sebanding dengan aktivitas air yang juga rendah. Penelitian ini adalah pertama yang menunjukkan ekstrak alga cokelat mengandung fukosantin dapat dimanfaatkan sebagai foodbars.Brown algae contains fucoxanthine as dominant carotenoid with high antioxidant activity. However, this carotenoid, including fucoxanthine, has not been fully utilized in food formulations because of their unstable property. Carotenoid needs stabilizing ingredient to be suitably used in food products. This study aims to analyze  the stability of brown algae extract by adding coconut sugar and cocoa fat that are formulated in the foodbars product, testing the antioxidant activity, proximate, texture, and stability of foodbars product containing fucoxanthine. Brown algae from Sumbawa Island are extracted using ethanol 96% to obtain fucoxanthine. Fucoxanthine analysis was performed using high performance liquid chromatography (HPLC) with a SPD-M20A diode array detector (Shimadzu). The antioxidant activity was tested using the DPPH method and the brown algae extract showed highest activity amongst all foodbars ingredients. Foodbars formula 2 (FB2) is most preferred by semi-trained panelists through organoleptic testing. In addition, the formulation of foodbars has similar texture to commercial product.  The result of the shelf-life test show low microbial growth in proportion to low water activity. This is the first study showing brown algae containing fucoxanthine used in the foodbars product.

Abstract

Antosianin merupakan senyawa bioaktif yang terdapat pada beras hitam dan memiliki aktivitas antioksidan. Penelitian ini bertujuan untuk mendapatkan ekstrak dan serbuk beras hitam tinggi antosianin, serta mengevaluasi sifat fisikokimianya. Proses ekstraksi antosianin dilakukan menggunakan metode maserasi dengan variasi perlakuan pelarut (air, air + asam sitrat 4% (b/v), dan etanol + asam sitrat 20% (b/v) sebagai kontrol) dan waktu maserasi (6, 18, 24, dan 48 jam). Hasil ekstrak kemudian dianalisis sifat kimianya. Selanjutnya, ekstrak dikeringkan menggunakan metode pengeringan semprot dengan variasi suhu pengeringan (160 dan 200 oC) dan penambahan maltodekstrin (10 dan 20%, b/v). Serbuk hasil pengeringan kemudian dianalisis sifat fisikokimianya. Hasil ekstraksi optimum ditandai dengan tingginya kadar antosianin total yang dianalisis menggunakan metode perbedaan pH dalam ekstrak. Kondisi optimum didapatkan pada ekstraksi menggunakan air + asam sitrat pada jam ke-24 yang ditunjukkan dengan kandungan antosianin total sebesar 0,85±0,02 mg/g. Pengeringan optimum yang ditandai dengan tingginya antosianin total (0,12±0,01 mg/g) dan %aktivitas penghambatan DPPH (46,22±0,24%) didapatkan pada sampel yang diekstraksi dengan air + asam sitrat dengan konsentrasi maltodekstrin 10% dan suhu pengeringan 200 ºC. Sementara itu, hasil analisis fisik yaitu kadar air, aktivitas air, kelarutan, dan viskositas serbuk setelah dilarutkan memiliki nilai yang menyerupai minuman serbuk komersial. Dapat disimpulkan bahwa ekstraksi antosianin beras hitam menggunakan metode maserasi dengan pelarut air + asam sitrat selama 24 jam dan dilanjutkan pengeringan semprot pada suhu 200 ºC menggunakan penyalut maltodekstrin 10% menghasilkan serbuk yang berpotensi untuk diaplikasikan sebagai ingridien minuman fungsional karena memiliki sifat fisik yang menyerupai minuman serbuk komersial dan memiliki aktivitas antioksidan.Extraction, Spray Drying, and Physicochemical Analysis of Black Rice (Oryza sativa L.)

Abstract

One of the Indonesian government's strategies to control the spread of the Covid-19 virus is to restrict people’s mobility when going out, which is often called the Implementation of Restrictions on Social Activities (PPKM). As a consequence of this PPKM, access to sufficient food tends to be rather limited. One effort to help people meet their food needs was through online tempeh-making training. This training, conducted online using Zoom and WhatsApp groups, involved community members who were connected through several health-related WhatsApp groups. The participants were all Indonesian from various areas, including the Greater Jakarta area, Ambon, Makassar, Medan, Padang, and even the US. Most of them were over 40 years old and were either employees or college graduates. Considering the significance of tempeh as a food item in Indonesia and a relatively affordable source of protein, the training became relevant in helping the participants to produce their own tempeh at home amidst the Covid-19 pandemic. After the training, all participants were found to be able to make tempeh with good quality and hygiene, with several participants even exhibiting creativity in processing their tempeh into more advanced tempeh products, such as tempeh noodles, tempeh pudding, and tempeh steak. In addition, their positive perception of tempeh as a healthy food item increased after attending the training.
