And Storage

<p class="Default">Purple sweet potato is rich in anthocyanin giving a potential application in food product development.  However, anthocyanin is relatively unstable and easily degraded during processing and storage. Understanding the stability and bio-accessibility of anthocyanin during processing, storage and simulated digestion is very important. The study aimed to investigate changes in anthocyanin degradation during processing, storage and simulated digestion of purple sweet potato pasta. The pasta was prepared through several processing steps, i.e. steaming the tuber, steaming the dough formula, extrusion, drying and boiling. Anthocyanin was analyzed at every stages of processing and storage of the pasta. The durability of the pasta during storage was analysed using an accelerated shelf-life testing method at 30, 40 and 50ºC for 28 days. The study showed that anthocyanin content decreased during the whole stages of processing and storage, but slightly increased during steaming. The highest loss of the anthocyanin occurred in the boiling process. Based on resistance to stomach and intestinal conditions, the bio-accessibility of anthocyanin was better in the digestive system in the stomach than that in the intestines. The increased anthocyanin appeared again in the colon. This study provides useful information for designing an effective method to minimize an extensive loss of anthocyanin of purple sweet potato for food product development.</p>

The Stability

The stability of colorant powders from Japanese purple sweet potato (Ipomoea batatas (L.) Poir) harvested in Vinh Long province was investigated. The colorants were formed from extracting solutions which were adjusted to pH of 6, 5, 4 and 3 before converted to powder matrix. They had red-purple color and contained anthocyanin concentration of about 32 mg/g. The IC50 inhibitory concentration of the neutral powder was 292.7 μg/mL, whereas the IC50 of pH3 powder was 484 μg/mL, which antioxidant activity decreased by increasing of acidic media clearly. Stability of appearance colors, anthocyanin content, polyanthocyanin index and antioxidant capacity were investigated and they depended on storing conditions (temperature and radiation) and pH media. To avoid denaturation of anthocyanin content, the pigment should be stored in the dark and at low temperature (10 °C). The acidic media could preserve the colorant powder by protecting anthocyanins, but it reduced the biological property of the pigment.

Purple Sweet Potato

<p>One of the sources of functional foodstuff is carbohydrate-based commodities which contain anthocyanin. These commodities include black rice, purple corn, and purple sweet potato. The anthocyanin compound is a pigment which is responsible for the purple color to the produced commodities. This compound possesses antioxidative activities which are able to bind with free radical compounds and protect human body against various diseases.Physiological function of the anthocyanin in foodstuff has attract particular interest for further exploration, particularly on its bioavailability nature, functional food ingredients, and its product’s appearances. Several anthocyanin-rich varieties such as Jeliteng black rice, Srikandi Ungu corn, and Antin purple sweet potato has been released by Indonesian Agency for Agricultural Research and Development (IAARD). In the future, development of processed functional food product is expected to raise in line with the increase in the public’s interest on the important of the health. The specific function of antioxidant derived from the anthocyanin compound enable human immunity increase which is recently getting popular, particularly during Covid-19 pandemic. Potential development of the foodstuffs associated with anthocyanin involves various research from upstream to downstream, starting from superior varieties development which contain higher anthocyanin content, by product creation with higher functional values and preferred by the consumers.</p><p>Keywords: Carbohydrates, anthocyanin, functional food, diversification.</p><p> </p><p><strong>Abstrak</strong></p><p><strong>PROSPEK PENGEMBANGAN KOMODITAS SUMBER KARBOHIDRAT KAYA</strong><br /><strong>ANTOSIANIN MENDUKUNG DIVERSIFIKASI PANGAN FUNGSIONAL</strong></p><p>Salah satu sumber bahan pangan fungsional adalah komoditas berbasis karbohidrat dan mengandung antosianin. Komoditas tersebut antara lain padi beras hitam, jagung ungu, dan ubi jalar ungu. Senyawa antosianin merupakan pigmen yang memberikan warna ungu pada produk yang dihasilkan. Antosianin memiliki aktivitas antioksidan, yang mampu mengikat senyawa radikal dan melindungi tubuh dari penyakit. Fungsi fisiologis dari antosianin dalam bahan pangan telah menarik perhatian untuk dilakukan eksplorasi sifat bioavailability, fungsi pangan fungsional, dan tampilan produknya. Beberapa varietas unggul komoditas sumber karbohidrat kaya antosianin seperti padi hitam Jeliteng, jagung Srikandi Ungu, dan ubi jalar ungu Antin telah dilepas oleh Balitbangtan. Ke depan, pengembangan produk olahan pangan fungsional diharapkan semakin meningkat seiring dengan meningkatnya perhatian masyarakat akan pentingnya kesehatan. Fungsi khusus antioksidan dari senyawa antosianin dapat menaikkan imun tubuh yang sangat dibutuhkan masyarakat, apalagi dalam masa pandemi Covid-19. Potensi pengembangan bahan pangan berantosianin memerlukan penelitian dari hulu hingga hilir, mulai dari perakitan varietas unggul mengandung antosianin lebih tinggi sampai teknologi pengolahan untuk menghasilkan produk olahan yang lebih berkualitas, dengan sifat fungsional yang lebih tinggi, dan disenangi oleh konsumen.</p><p>Kata kunci: Karbohidrat, antosianin, pangan fungsional, diversifikasi.</p>

Food Product Development

New methods for combined evaluation of nutritional and environmental aspects of food products are needed to enable a transformation of dietary guidelines integrating both health and environmental perspectives. We evaluated two sustainability aspects; nutrition and climate impact, of foods commonly consumed in Sweden and the implications of using parallel or integrated assessments of these two aspects, also discussing the usability and suitability of these food sustainability indicators in relation to Swedish dietary guidelines, industry food product development, and consumer communication. There were large differences in both nutrient density and climate impact among the different foods. The parallel assessment easily visualized synergies and trade-offs between these two sustainability aspects for the different foods. Coherence with dietary guidelines was good, and suitability and usability deemed satisfying. The integrated indicator showed better coherence with dietary guidelines than indicators based solely on nutrient density or climate impact; however, the difficulty to interpret the score limits its usability in product development and consumer communication. With both methods, advantageous as well as less advantageous plant-based and animal-based food alternatives were suggested. The two alternative methods evaluated could serve as useful tools to drive individual and societal development towards more sustainable food production and consumption.
