Abstract

Crispness as one of the important parameters for chips quality wants to be pursued. In this research, heat treatments before frying, such as steaming and boiling, were expected can help preparing the porous structure in the chips material before frying through the gelatinization mechanism. The porous structure is an important factor in crispness. Raw materials used were tuber crops, such as cassava and purple sweet potato. The aims of this study were to determine the effect of the heat treatments before frying on the chips crispness and obtain the heating process temperature and time that could produce chips with the best crispness. Chips crispness was analyzed using a rating test as organoleptic test and texture analyzer as physical test. Cassava and purple sweet potato slices steaming and boiling treatments before frying increased the chips crispness (P<0.05). Steaming of cassava slices for 5 minutes at a temperature of 100°C or boiling them for 3 minutes at a temperature of 95°C and steaming of purple sweet potato for 3 minutes at a temperature of 100°C or boiling them for 1.5 minutes at a temperature of 95°C before frying became the best time to improve the chips crispness organoleptically and physically compared with control. The treated cassava chips water and fat content changes didn’t affect their crispness.

Abstract

Bioactive peptides have important role as functional food ingredients. The sequence patterns of amino acids in peptide fragments may relate to their functional mechanisms. On the contrary, presence of an amino acid in a peptide fragment might not be sufficient to provide a unique identifier toward the bio-active peptide functional properties as antihypertensive (AH), antioxidative (AO) or antimicrobial (AM) agents. The main objective of this study was to explore the identifiers of bioactive peptides based on the sequence-generated properties. This study was performed using meta-analysis by utilizing many data sources and qualified international journal publications. The identifiers of bioactive peptides include sequence length, molecular weight, isoelectric point (pI), net charge and hydrophobicity. Based on the average score of the five identifiers, antimicrobial (AM) peptides were very different from antihypertensive (AH) and antioxidative (AO) peptides. The comparisons of the peptide biofunctional properties based on the identifiers may be determined as follows: AH1<AO1<AM1 (for sequence length); AH1<AO1<AM1 (for molecular weight); AH1=AO1<AM1 (for isoelectric point/pI); AH1=AO1<AM1 (for net charge) and AH1<AM1<AO1 (for hydrophobicity).

Abstract

Homogenization is one of the key processes in the production of UHT milk. This process is designed to reduce the size of fat globule, thus decreases the possibility of milk fat separation during storage. To ease the monitoring of successful homogenization process, homogenization degree (homodegree, oH) is commonly used instead of direct measurement of fat globule size using particle size analyser (PSA). This study was aimed to investigate the correlation between the resulted homodegree and the results of particle size analysis using PSA. There were two UHT milk variants used, A and B. Within this study, UHT milk fat globule of variant A dan B had mean diameter of 0.314 ± 0.020 μm and 0.228±0.005 μm, respectively. By this, a higher value of oH was resulted from UHT milk variant A. The homodegree was sensitive respective to the change of particle size of UHT milk for each variant. Additionally, homodegree was found to have a poor correlation, i.e., based on coefficient of determination (R2) especially for smaller size of fat globules (d10). However, this correlation was evaluated to increase for larger fat globules (d50, d90). Homodegree was also found to have poor correlation either with pressure or inlet temperature applied in homogenization. Despite some miscorrelation found between the homodegree and pressure or temperature of homogenization, measuring homodegree below 13.5 was still found sufficient to indicate successful homogenization in which UHT milk fat globule size was below 0.4 μm. Keywords: fat globule, homodegree, homogenization, particle size analysis, UHT milk

Abstract

Melinjo chips (emping as local name) has high purine content which can be related to the high uric acid level in blood that lead to joint inflamation due to the sendimentation of uric acid. The objective of this research is to prove that soaking process can reduce purine content in emping and to know the effect of the soaking process length in purine reduction. Soaking time (2, 5, and 12 hours) and emping brand (Sriti, A1 and Koki) were used as the treatments. Purine compounds such as adenine and hypoxanthine were analyzed by using High Performance Liquid Chromatography (HPLC) method with C18 column and UV detector. The three emping samples were also analyzed by using sensory evaluation to know the consumer preference toward the treated fried emping. Results obtained from this research were that soaking process can reduce both adenine and hypoxanthin content in emping. Soaking for 2 hours in water could reduce adenine content 13 – 39% and hypoxanthine content 4 – 60%. Soaking process for 2 hours on emping could reduce up to 50% of total purine base content in A1 brand, however, soaking time was not directly proportional to the decrease in purine levels. Purine content after 5 and 12 hours soaking tend to be fluctuative. Emping samples that were soaked in the water have a decrease in preference by the panelists either in color, aroma, taste, texture or in overall, but still accepted by panelists.
