Abstract

Crude palm oil (CPO) purification aims to remove or degrade unwanted components such as free fatty acids (FFA), phospholipids, impurities, color pigments, metals, and odors. The CPO purification generally consists of degumming, bleaching, and deodorization process. During the stages, some undesirable compounds are formed, including 3-monochloropropane-1,2-diol ester (3-MCPDE) and glycidyl ester (GE). The main precursors responsible for formation of the two compounds are chlorides and acyl glycerol fractions, especially diacylglycerol (DAG) and this occurs high temperatures in the deodorization process. Therefore, it is necessary to reduce their precursors in order to supress the contaminants. To cope with the problem, a washing process of CPO was proposed as an extra process before a purification stage. The washing process was carried out in two ways, namely wet washing by using water, and dry washing by using bleaching earth (BE) by 2 types of commercial BE (natural and acid activated). Washing processes using wet and dry washing (natural and activated BE) showed comparable effectiveness in reducing 3-MCPDE and GE levels in refined palm oil. As a result, the process successfully reduced 3-MCPDE content to comply with a standard Commission Regulation (EU) 2020/1332, but GE content did not conform to standard.

Abstract

Starch is extensively utilized in food processing for various purposes. However, the use of native starch is limited due to its unsuitability with processing conditions or products characteristics. Physical modification of starch is commonly employed to enhance the properties of native starch. The physical starch modification using microwave heating is presently developed due to its more efficient energy consumption than that of traditional heating methods. The process of microwave heating followed by cooling has been found to induce the formation of type 3 resistant starch (RS3). However, the effects of microwaving heating towards the the increase of resistant starch contents varies among researchers. For this reason, a meta-analysis was conducted to evaluate the effect of microwave heating on the levels of resistant starch in carbohydrate sources such as cereals, pulses, and tubers. The objective of this study was to analyze the carbohydrate food groups that demonstrated the most significant increase in resistant starch levels due to microwave heating, and to determine the optimal microwave treatment parameters within these food groups using meta-analysis. The findings indicate that microwave heating treatment is particularly effective for cereals, with rice being the most responsive. The most favorable treatment parameters include a power range of 401-600 W, heating time of 60-99 s, and starch moisture content of 40-60%.

Abstract

Garlic (Allium sativum) oleoresin is susceptible to damage such as easily volatile and oxidized. It also has low solubility in water. Microencapsulation process is expected to overcome the disadvantages. The aim of this study was to obtain garlic oleoresin microcapsules through twin-screw extrusion process. The study was done by determining the suited carrier, i.e. β-cyclodextrin, dextrin, or maltodextrin, to be used in the microencapsulation of garlic oleoresin, and determining the optimum garlic oleoresin microencapsulation parameters based on response surface methodology (RSM) using the suited carrier. β-cyclodextrin was found to be the suitable carrier for the garlic oleoresin microencapsulation process using a twin-screw extruder. The usage of maltodextrin and dextrin was not possible due to the high viscosity of the mass observed which led to blockage. The modeling obtained through the RSM showed that the combination of the components (carrier, oleoresin, and water) was not ideal for optimum solubility and surface oil. However, the parameters and optimum formula obtained had good experiment repeatability. The optimum garlic powder obtained through the extrusion process showed low surface oil as much as 2.20% and solubility as much as 33.80%. The microencapsulated product exhibited better quality characteristics than commercial K brand spray-dried garlic powder. The extruded powder had nearly four-fold lower aroma intensity prior to dilution, and nearly three-fold higher aroma intensity when diluted in 60°C water.

Abstract

Various flavoring agents purchased by micro small medium enterprises (MSME) could be obtained through online marketplace. Their types and legalities have never been investigated in Indonesia. The objective of this study was to obtain an overview of the availability of the flavoring agents on online marketplace and their legality. The legality is defined as the flavoring agents which are marketed and have its compliance to regulation of Indonesian Food and Drug Agency (BPOM), otherwise is illegal. The profiles of online marketed flavoring agents on marketplace are obtained through online survey of flavorings advertisements documented using a check sheet as the tool. Tokopedia and Shopee were chosen as samples in this study because they both are the most popularly e-commerce sites clicked by consumers. A non-probability sampling and sample screening were carried out to obtain eligible samples until it achieved a predetermined amounts. There were 399 flavoring agents observed, with result of 262 legal flavoring agents (65.7%) and the rests were illegal. Mostly, they were of domestic flavorings (98.5 and 88% respectively). The cases of non-conformities forward the rules were: advertising without packaging, repacking, unregistered brands, and incompatible information in their packaging and/or labels when it was cross-checked with BPOM data. Due to the high number of illegal flavoring agents sold online, monitoring of the online flavoring markets should become a priority program of Indonesian government, while consumers need to be cautious. The traders and producer have an urgent action in taking a moral responsibility for the legality of the flavoring agents being marketed.

Abstract

Consuming foods with a low glycemic index, such as sweet corn (Zea mays Saccharata), which has a high fiber content, can help lower the risk of diabetes. According to previous research, sweet corn is predicted to have a low glycemic index (GI). The study's goals were to determine the value of the glycemic index of corn and to produce low glycemic index instant flake products made from sweet corn and red beans. The glycemic index value of sweet corn was determined using a glycemic index test technique based on ISO 26642:2010E. The flakes was made with the addition of red beans reported to have the lowest glycemic index among legume, i.e. 26 in order to enhance the crude protein content of the flakes. Flakes were made in two formulas based on the proportion of red beans to sweet corn, namely formula 1 (30:70) and formula 2 (70:30). Proximate analysis was done according to AOAC 2005, total dietary fiber analysis according to AOAC Official Methods 985.29, and total starch analysis according to AOAC 2002.02. Texture analysis of the flakes was carried out using a texture analyzer and color analysis using a chromameter. The sweet corn was found to have a low GI (<55) i.e. 36. Formula 1 flakes contained more fat (db), carbohydrate (db), and total starch (db); while formula 2 flakes had more moisture, protein (db), and resistant starch (db). The resulting flakes have crispy texture (hardness of 553±5.09 gf for formula 1 and 519.05±6.86 gf for formula 2) and have yellow color (both are included in the yellow chromatic area).

Abstract

Velvet beans are potential sources of parent proteins for bioactive peptide production. In this study, a combination of fermentation and neutrase-catalyzed continuous hydrolysis in an enzymatic membrane reactor was performed to produce antioxidative and angiotensin I-converting enzyme inhibitory (ACEi) peptides. The optimum operating conditions were τ = 6 h and [E]/[S] = 7.5%. The resulting permeate, which was a<10-kDa fraction, exhibited antioxidant activity at 0.38 mg ascorbic acid equivalent antioxidant capacity (AEAC)/mL (2,2-diphenyl-1-picrylhydrazyl, DPPH inhibition) and 0.26 mg AEAC/mL (ferric reducing antioxidant power, FRAP), and ACEi activity of 81.02%. Further fractionation of the permeate increased the ACEi activity in which 2-kDa fraction showed the most potent activity (IC50 = 0.23 µg protein/mL). The IC50 value of the outcome was comparable to those reported in the literature for velvet bean-based peptides. Furthermore, this study suggests that neutrase is a good catalyst candidate for the synthesis of bioactive peptides from velvet beans.

Abstract

Restriction of trans fatty acids (TFA) in the diets due to their negative impacts on health has led to the development of various TFA-free products. Blending is one of the common methods used to obtain TFA-free fats. This study aimed to obtain optimum formula of TFA-free oil, designed by using Design Expert 13 mixture with a simplex-lattice design for chocolate filling application. There were four types of oils, namely palm oil (PO), palm olein (PL), palm kernel oil (PKO), and chemically interesterified palm oil (CIE). Analysis was performed on chemical and physical properties of the oil blends as well as the physical properties of chocolate filling made from the oil blends. Commercial partially hydrogenated oil (PHO) was used as a comparison. The results showed that two out of six oil blends were recommended by the software, and both conformed to the specifications of commercial PHO, namely E (blend of 48% CIE and 52% PL) and F (blend of 33% CIE, 21% PKO, 17% PL, and 29% PO). The induction period (IP) and crystallization rate of sample E and F are lower than PHO. All chocolate fillings showed good emulsion stability (oil released <0.1%). The texture of chocolate fillings F and E were softer than PHO. Principal component analysis and orthogonal partial least square-discriminant analysis graphs showed that all samples were located in different cluster, but sample F was closer to PHO compared to E. In conclusion, although the optimum blends obtained through the use of Design Expert had similar solid fat content to PHO, the chemical and physical characteristics of the oil blend and chocolate filling were significantly different from PHO. Therefore, there is a further need to evaluate the use of E or F blends to replace PHO.

Abstract

Fish is one of the nine major food allergens. Avoiding consumption of fish is a common preventive measure to mitigate fish allergies. On the other hand, food processing may potentially alter the allergenicity of fish, and thus, it is important to identify the most effective fish processing methods that can reduce its allergenicity. This research aimed to characterize the nutritional value, intensity of allergens, and allergenicity from the processing of tenggiri fish processing to produce surimi as intermediate food and ready to eat (RTE) otak-otak. The processing steps consisted of washing and adding cryoprotectant during surimi processing, and using deep and air frying methods in RTE otak-otak processing. Changes in the nutritional value and intensity of allergens of fish meat and its processed products were measured using proximate analysis and SDS-PAGE electrophoresis, respectively. The alterations in the allergenicity were investigated using immunoblotting and ELISA. The results revealed changes in the nutritional value due to the processing. Surimi production successfully removed a protein band of 10-–13 kDa, which is suspected to be an allergen. Additionally, both deep and air frying methods effectively removed allergenic proteins with molecular weights above 100 kDa. Immunoblotting assay showed the allergen only appeared in fish meat absent in all of the processed products. The allergenicity rates of surimi and otak-otak was reduced by 90.78 and 98.68%, respectively, as compared to the fish meat. In conclusion, the nutritional value of air-fried otak-otak is superior while the allergenicity is lower than the deep-fried ones. Therefore, air frying processing method for tenggiri fish can be potently used to produce hypoallergenic fish products.

Abstract

Blanching is the most common pretreatment method for fruits and vegetables to maintain product quality. Numerous studies revealed desirable impacts of the process to total phenolic content, while the others showed opposite results. In addition, some differences in the blanching condition such as methods and classification of fruits and vegetables were also known able to affect total phenolic content. This study aimed to analyze the effect of blanching on total phenolic content in vegetables and fruits through a meta-analysis approach. Study selection was conducted with a PRISMA method. There were 28 articles and 82 data used for meta-analysis. The data were analyzed by Hedges’d to calculate the effect size with confidence interval (CI) utilizing OpenMee software. The result showed that blanching demonstrated significant effects on the rise of total phenolic content (hedges’d[95% CI]: 0.782 [0.037 to 1.527]; p<0.05). Based on fruits and vegetables subgroups, the blanching significantly affected the increase of total phenolic content in leaves (hedges’d[95% CI]: 1.484 [0.185–2.782]) and fruits (hedges’d[95% CI]: 2.504 [0.153–4.854] compared to stems and stalks, fruits as vegetable, shoots and sprouts, pulse, and flowers. Meanwhile, in terms of blanching method subgroups, hot water blanching (hedges’d[95% CI]: 1.096 [0.234–1.959]) had significant effects on the rise of total phenolic content compared to steam blanching. Moreover, this meta-analysis was robust against publication bias.

Abstract

Variations of processing rice into cooked rice had long been developed. One of the rice products that had been widely circulated in the community was savory rice. Savory rice with an instantization processed was more practical in serving. This research aimed to determine the physical, chemical, functional, and sensory characteristics of instant savory rice compared to instant white rice. The stages of processing instant savory rice included washing, soaking, cooking, freezing, and drying. The freezing process was carried out at -20 °C for 24 h. The drying process for instant savory rice used a fluidized bed dryer for 3 h. Instant white rice was used as a control. The porosity level of instant savory rice was lower than instant white rice as indicated by the yield (95.77%), bulk density (0.57 g/mL), rehydration time (14.34 min), rehydration ratio (2.86), expansion volume ratio (2.26), and water absorption capacity (69.50%). Instant savory rice contained moisture content (8.48%), ash content (3.93%), fat content (5.56%), protein content (7.54%), and starch digestibility (54.84%) which was higher than instant white rice. Instant savory rice had carbohydrate content (82.97%), amylose content (32.39%), amylopectin content (46.59%), starch content (79.98%), and resistant starch content (1.90%) lower than instant white rice. In terms of sensory test results revealed that instant savory rice after rehydration was preferred by consumers compared to instant white rice regarding color, aroma, taste, texture, and overall with a score of 5.39-5.84.
