Abstract

The waste of shrimps in the form of skin, head, and tail that is disposed from shrimp processing and disposal are usually thrown away with out being processed, therefore the wastes may cause environmental pollution, especially from the unpleasant stench. Shrimp wastes contain compounds called chitin and can be utilized to absorb heavy metals which are mainly from industrial wastes. The batik industries in Solo usually utilize synthetic colors, because synthetic colors are cheaper and can make the products look more satisfying. Nevertheless, the liquid wastes from these batik industries are usually still colorful when it is disposed and are usually hard to be degraded by nature. Moreover, these wates contains heavy metals such as lead (Pb) and copper (Cu) that can endanger the human health. This research is conducted in order to notify the performance of chitin in order to absorb heavy metals such as lead (Pb) and copper (Cu). There are five treatments that is conducted in this research by adding chitin powder as much as 0 g (control), 1, 2, 3 and 4 g into the sample of batik liquid wastes. The lead (Pb) and copper (Cu) substance of the sample will then be measured using the AAS (Atomic Absorption Spectrophotometer), then the lead (Pb) and copper (Cu) substance of each treatment will be compared with the control. The result of the research shows that chitin can reduce the content of lead and copper in batik liquid wastes. Based on the research result, it is concluded that the addition of 4 g of chitin powder into the sample of batik liquid wastes can give the most maximum result, i.e. the reduction of the Pb content by 6.138 ppm from the control of 17.773 ppm into 11,635 ppm, and the reduction of the Cu content by 3.779 ppm from the control of 7.903 ppm into 4.104 ppm.

Abstract

Industrial waste-water has become a serious problem nationwide. However, one type of waste-water, i.e. tofu waste-water (whey), can be utilized as the source of nata de soya production. This present research is attempts to reveal the effect of various concentrations of inocula and green-bean extracts on nata productions from tofu waste-water. Ten combinations of treatment were applied and coded as A1 – A10. The parameters observed included physical and chemical characters of nata and nitrogen (N) contents. The results show that the increase in concentration of N and inocula will follow by the increase of water content, fiber content, plasticity, and N content of nata de soya produced. Highest thickness of nata was gained at 200 g/L concentration of green-bean extract and 100 ml/L concentration of inoculum.

Abstract

Minimally processed fruits provide convenience and freshness characters. Weight loss is a critical factor affecting the shelf life of minimally processed apples. These apples were limited by brown coloration that develops on surface. The objective of this study is to evaluate the effectiveness of edible coat and film made from aren starch against weight loss and browning on minimally processed apples. Edible coat and film solutions were prepared from 3% (w/v) aren starch, 6% (w/w) palmitic acid, and 1% (w/v) sorbitol. Minimally processed apples were either dipped in the coating solution or wrapping by edible film and then stored at ambient temperature for 8 hours. Browning appearance was determined every 4 hours and weight loss of apples was measured every hour.  Edible film was much effective on weight loss control than coating during storage. Color analysis showed that pati aren edible  coating and film wrapping did not significantly delayed browning reaction on  minimally processed apples.

Abstract

Bekatul merupakan produk samping dari penggilingan biji serealia seperti beras, gandum, dan barley. Bekatul memiliki harga yang murah, namun tinggi akan serat dan kandungan antioksidan yang dapat memberikan efek kesehatan bagi tubuh. Serat pada bekatul dapat menurunkan kadar kolesterol serta dapat meningkatkan waktu transit feses. Kadar serat pada bekatul beras lebih tinggi dibandingkan dengan kadar serat pada bekatul gandum dan barley. Roti merupakan produk hasil pemanggangan yang terbuat dari campuran tepung gandum, dimana kadar serat tepung gandum sebesar 1,35%. Kebutuhan serat harian adalah 25-30 g. Selain itu, adanya kandungan antioksidan pada bekatul dapat berfungsi sebagai anti-inflamasi, menurunkan resiko penyakit jantung koroner, serta mencegah terjadinya penyakit Alzheimer. Penambahan bekatul perlu dilakukan untuk memenuhi kebutuhan serat harian dan menaikkan nilai gizi pada produk. Namun, perlu diketahui bahwa penambahan bekatul dengan konsentrasi tinggi dapat menyebabkan tekstur roti menjadi keras volume roti mengecil, serta warna roti menjadi lebih gelap. Oleh sebab itu, perlu diketahui konsentrasi penambahan bekatul pada roti agar dapat mengurangi efek merugikan yang ditimbulkan oleh bekatul. Konsentrasi penambahan bekatul yang ideal adalah 1-10% (Irakli et al ., 2015).

Abstract

Getuk is an Indonesian traditional food made from cassava. Getuk has short shelf life, which is 12-15 hours caused by the high water content in getuk that is make getuk easily contaminated by microbes. Biopreservation is a safe solution to overcome this problem, one of which is by using bacteriocin. Bacteriocin is safe to use as a biopreservative because it is not toxic and can be digested by the protease enzyme so it will not affect the microbiota in the intestine. Bacteriocin used in this study is bacteriocin produced by Lactobacillus plantarum because it is a safe microbial and included in GRAS (Generally Recognized as Safe) and has broad spectrum properties, which can kill gram-positive, gram-negative, and pathogenic bacteria. This research will discuss further about the ability of bacteriocin from Lactobacillus plantarum as a biopreservative agent in getuk. Bacteriocin from Lactobacillus plantarum will be microencapsulated using spray drying before adding to getuk. The treatments taken are variations in the addition of bacteriocin to getuk and variations in storage time. The variation of bacteriocin addition in getuk is 0% (control), 2,5%, 5%, and 7,5%, the variation of getuk storage time is 0-3 days. Cassava getuk will be tested physically, chemically, and microbiologically during the storage time. The results obtained in this study are the addition of 7,5% bacteriocin powder can increase getuk shelf life for 1 day. On storage day 1, the result of microbe in getuk is still within the national standard safe limits and getuk does not smell sour and there is no yeast that grows on getuk.

Abstract

ABSTRACT Secang (Caesalpinia sappan) is known as a red coloring agent in histological staining. One of the active components found in Secang is the brazilin compound. These compounds are reported to have biological activities such as hypoglycemic and antioxidants. The formation of resistant starch in traditional food processing such as secang rice as an effort to reduce blood glucose levels has never been reported. The aims of this study were to determine the total phenolic and antioxidant activity of secang wood extract in the manufacture of secang rice, and to determine the levels of resistant starch of secang rice with different concentrations of addition of secang wood extract. This research was conducted using 4 treatments of secang wood extract, control (without secang wood extract), 5 mL, 7.5 mL, and 10 mL of secang wood extract. The parameters analyzed were total phenolic, antioxidant activity (DPPH) in secang extract and secang rice, and content of resistant starch in secang rice. The results showed that the total phenolic extract of secang wood was 3524.03 ± 20.42 mg GAE / 100 g of the sample and the percent inhibition of free radicals was 94.01 ± 1.76%. The higher the addition of secang wood extract to 10 mL is, the higher the total phenolic and percent free radical inhibition in secang rice. The highest total phenolic and percent free radical inhibition was found in rice which was added with 10 mL of secang extract, i.e. 13.75 ± 0.96 mg GAE / sample and 75.77 ± 0.77%, and the highest resistant starch content was 1.6 ± 0.24%.   ABSTRAK             Secang (Caesalpinia sappan) dikenal sebagai bahan pewarna merah dalam pewarnaan histologi. Salah satu komponen aktif yang terdapat pada secang adalah senyawa brazilin. Senyawa ini dilaporkan memiliki aktivitas biologi seperti hipoglikemik dan antioksidan. Pembentukan pati resisten dalam pengolahan pangan tradisional seperti nasi secang sebagai upaya menurunkan kadar glukosa darah belum pernah dilaporkan. Tujuan penelitian ini untuk mengetahui total fenolik dan aktivitas antioksidan ekstrak kayu secang dalam pembuatan nasi secang, serta mengetahui kadar pati resisten nasi secang dengan konsentrasi penambahan ekstrak kayu secang yang berbeda. Penelitian ini dilakukan menggunakan 4 perlakuan ekstrak kayu secang yaitu kontrol (tanpa ekstrak kayu secang), 5 mL, 7,5 mL, dan 10 mL ekstrak kayu secang. Parameter yang diuji adalah total fenolik, aktivitas antioksidan (DPPH) pada ekstrak secang dan nasi secang, serta kadar pati resisten pada nasi secang. Hasil penelitian menunjukkan bahwa total fenolik ekstrak kayu secang sebesar 3524,03 ± 20,42 mg GAE/100 g sampel dan persen penghambatan radikal bebas 94,01 ± 1,76%. Semakin tinggi penambahan ekstrak kayu secang hingga 10 mL, maka semakin tinggi total fenolik dan persen penghambatan radikal bebas pada nasi secang. Total fenolik dan persen penghambatan radikal bebas tertinggi terdapat pada nasi yang yang ditambah 10 mL ekstrak secang yaitu 13,75 ± 0,96 mg GAE/sampel dan 75,77 ± 0,77%, serta kadar pati resisten tertinggi sebesar 1,6 ± 0,24%.

Abstract

Virgin coconut oil (VCO) is a pure coconut oil made from mature and fresh coconut meat. VCO is consumed for health-related reasons, but the unsaturated fatty acids of VCO are prone to oxidation. Mixing VCO with peppermint oil, which contains antioxidants, inhibits the oxidation of unsaturated fatty acids and thus prevents the rancidity of VCO. This research used the antioxidants from peppermint oil to improve VCO quality. VCO contains antioxidants, such as α-pinene, menthol, 1,8-cineol, camphor, flavonoid, borneol, tocopherol, and carotene. The treatments consisted of three peppermint oil concentrations (2.5%, 5%, and 7.5%) in VCO. Results showed that the additionof peppermint oil significantly improved VCO quality. The optimal concentration of peppermint oil in VCO was 7.5% with a water content of 0.05%, a free fatty acid value of 0.13%, a peroxide value of 0.53 mg eq/kg, an iodine value of 4.42 g I2/100 g, a total plate count of 0 cfu/mL, and antioxidant activity of 90.28%.
