Indonesian Food and Nutrition Progress, is a primarily online, a peer-reviewed journal in food technology and nutrition. All papers should focus on the novelty of the research carried out. It is published by Indonesian Association of Food Technologists in collaboration with Faculty of Agricultural Technology, Gadjah Mada University. This journal is published two times a year which is a continuation of the last publication in 2005. The journal is devoted to a rapid peer reviewed full-length original research paper, short communications, and critical reviews, which serves as an international forum for the exchange of information in all aspects of food technology and nutrition. Food and Nutrition Progress includes a wide range of food technology and nutrition topics such as: Physical, chemical, biotechnological, microbiological, process engineering, analytical, and nutritional aspects; Post-harvest technology; Sensory evaluation; Diet plans; Gastronomy; Food safety and hygiene; Functional foods; Novel foods.

Abstract

This study aimed to investigate the retrogradation rate of heat moisture treated sago and arenga starches using different approaches, including a thermal approach using DSC (differential scanning calorimetry), a rheological approach using dynamic viscoelasticity as rheological and syneresis level. The autoclaving procedures prepared the HMT starches at 20% moisture content and warmed to 120 °C for 60 min and 90 min for sago and arenga starches, respectively. The Avrami equation was used to express starch retrogradation kinetics based on gelatinization enthalpy (ΔH). The Avrami exponent (n) of HMT and native starches were close to 1.0 (0.77 – 1.20) indicates rapid nuclei growth of the crystal. HMT has a significant influence on the retrogradation of sago starch, both from the values of n and k of the Avrami equation. On the other hand, it does not have a significant effect on arenga starch. Based on the thermal approach (DSC), HMT significantly affects sago starch’s retrogradation rate, but there was no effect on arenga starch. The influence of HMT on the retrogradation rate of arenga starch was observed on rheology and syneresis approaches, although it was not as high as sago starch.

Abstract

Traditional food is usually packed with natural packaging materials such as young coconut leaves (janur), but a little scientific information is available related to the packaging material. This study aimed to examine the physical and chemical characteristics of fresh and steamed janur (30 minutes steaming at 100 °C). The physical and chemical properties of janur were expected to be the basis for the development of janur as an environmentally friendly packaging material. The results showed that fresh and steamed janur color was greenish-yellow and brownish-yellow. The fresh and steamed janur had a tensile strength 19.19 MPa and 30.62 MPa; water content 73.54% and 69.57%; and fat content 1.85% and 0.54%, respectively. After steaming, the microstructure of the cells became finer and irregular. The dominant fatty acid in fresh janur and steamed janur was palmitic acid (24.27%), and palmitoleic acid (38.56%), respectively. The treatment of steaming of janur influenced the physical and chemical characteristics of packaging materials.

Abstract

Teak (Tectona grandis) leaves is commonly used as the packaging material of traditional food in Indonesia. This study aimed to determine the physical and chemical characteristics of teak leaves with various maturation stages to obtain information about the potency of teak leaves as active packaging material. The physical characteristics analysis including leaf color, thickness, and tensile strength, while chemical characteristics were moisture, fat content, fatty acid, and volatile profile. The results showed that the color, thickness, tensile strength, moisture, and fat content, were light green, 0.306±0.024 mm, 0.22±0.114 MPa, 74.93%, and 2.52% respectively for young teak leaves; while the mature has darker green, 0.388±0.001  mm, 0.36±0.163 MPa, 73.05%, and 2.54% respectively. The fatty acid profiles showed that young teak leaves contained 5 types of fatty acids, dominated by lignoceric acid; while mature teak leaves contained 9 types of fatty acids dominated by tricosanoic acid. The volatile components of young teak leaves e.g. acid and ester compounds, while the mature was dominated by acid and ether compounds. From the results, it is suggested that the use of teak leaves as active food packaging material can be scientifically justified.

Abstract

Arabica coffee is the most popular variety of coffee among the people because it has a more complex flavor than other coffee varieties. This study aims to determine sensory properties and non-volatile components in Arabica coffee fermented with sugar addition. The sensory assessment showed that the best cupping score was the samples fermented with the addition of 0.55% fructose with a total score of 85.25 compared to honey (H) and Fullwash (FW) samples. Fermentation with the addition of 0.55% fructose could produce better coffee compared to samples (H) and (FW). Fermentation with the sugar addition of 0.55% could affect non-volatile components such as soluble sugars, organic acids, amino acids, caffeine, and chlorogenic acid. The content of chlorogenic acid and caffeine analysed by HPLC was found relatively stable in green and roasted beans. Amino acids analysed by LCMS showed glutamate was the highest amino acid in all samples and were supposed to have a role in Maillard reaction contributing to coffee flavor. In conclusion, fermentation with the addition of 0.55% sugar in coffee processing could generally enhance the coffee flavor for brew taste with its potential as functional drink.

Abstract

Hawaijar is an ethnic fermented soy product from the North-East region of India. The information on the effect of soybean genotype and the Bacillus subtilis strain used for inoculation for preparing the product on the fatty acid composition, the level of antinutritional factors, such as Kunitz trypsin inhibitor (KTI) and Bowman-Birk inhibitor (BBI), and oligosaccharides is not available. In the present study, Hawaijar was prepared from two soybean genotypes using two different strains of Bacillus subtilis and investigated for the concentration of the above-mentioned biomolecules. The results showed the significant effect of genotype used on oleic, linoleic, and α-linolenic acid of the product. KTI and BBI were found absent in Hawaijar prepared from these two genotypes and two strains. Flatulence-inducing factors like raffinose and stachyose were found in very low concentration irrespective of genotype and strain. Retention of sweetness-imparting sucrose and maltose concentration in Hawaijar was genotype-dependent.
