Abstract

AbstractPacri nanas is a traditional Malay food made from fresh pineapple cooked with various herbs/spices and coconut milk. Pacri nanas can be marketed more widely if packed in cans. This study aims to estimate the shelf-life of canned pacri nanas using the Accelerated Shelf-Life Test (ASLT) method. The storage temperatures used in this study were 35 °C, 45 °C, and 55 °C. The parameters observed were sensory characteristics: color, aroma, taste, texture, and overall appearance. The results showed that all parameters decreased during storage, as indicated by the negative slope graph. The first-order reaction affects the sensory parameters decrease during storage. The lowest activation energy (Ea) value used to determine the product shelf-life is the aroma parameter with the regression equation y = -2416.4x + 5.9911, so the resulting activation energy is 4798.97 cal/mol. The shelf-life of pacri nanas at storage temperatures of 35 °C, 45 °C, and 55 °C were 11.3, 8.8, and 7.0 months, respectively. Storage of canned pacri nanas is recommended at room temperature (30 °C) with an estimated shelf-life of 12.8 months.Keywords: pineapple, storage life, traditional food AbstrakPacri nanas adalah makanan tradisional Melayu yang terbuat dari nanas segar yang dimasak dengan berbagai bumbu/rempah dan santan.

Abstract

Liquid sugar is a sweetener that is widely used in the food industry. Apart from starch, liquid sugar can be produced from cellulose hydrolysis by using cellulase enzymes. This study aims to obtain the best concentration of cellulase enzymes in the production of cellulose liquid sugar in the skin of red dragon fruit. The production of liquid sugar uses the method of hydrolysing enzymes of different concentrations (1%,2%,3%). The results showed that there was no significant influence on the characteristics of liquid sugars resulting from the addition of three different enzyme concentrations. The observed characteristics are total sugar content, water, ash content, viscosity and color. Enzyme concentration of 3% is the best liquid sugar based on observations of total sugar content and color.

Abstract

The main cause of stunting is due to inadequate food intake according to the needs for growth and development of children, or insufficient nutrition of pregnant women. The low nutritional intake of pregnant and lactating mothers as well as children under five years old who are still growing and developing is generally caused by the wrong diet. One of the efforts to prevent stunting from an early age is to search for several sources of animal source food containing protein, fat and macro essential minerals according to nutritional standards. The purpose of this study was to determine the proximate content including protein and fat nutrition, water content and ash content, as well as mineral content including calcium, iron and phosphorus, from Tembakul (mudskipper) fish flour as the main needs in the growth of children, during pregnancy and lactation. Protein analysis was carried out using the Kjeldahl method, and fat analysis by extraction using a non-polar solvent, while the determination of essential macro minerals calcium and iron was carried out using an Atomic Absorption Spectrophotometer, and phosphorus analysis using ultraviolet spectrophotometry. The proximate content of Tembakul (mudskipper) fish flour from the Mempawah mangrove ecosystem is fat content (1.80%), protein content (50.67%), water content (24.58%), and ash content (20.20%). Mudskipper fish flour contains 3 essential minerals, namely Calcium (2.15%), Phosphorus (2.50%) and Iron (270.26 ppm).

Abstract

Semprong is one of Indonesia's signature cookies with a crunchy texture and roll-like shape. The main raw material commonly used in kue semprong is white rice flour. Brown rice is an alternative to rice flour for making kue semprong because its utilization in the food industry sector is still very limited. Rice, which is included in the cereal group, is low in the amino acid lysine, so it would be better if it is paired with other raw materials, such as beans such as green beans. The objective of this study was to obtain the right ratio of brown rice flour and mung bean flour to produce the best abacus cake formulation based on physicochemical and sensory characteristics. Based on the results of the research, the best abacus formulation with the highest score is P3, which is a ratio of 60% brown rice flour and 40% mung bean flour with a moisture content of 3.30%, protein content of 16.80%, ash content of 1.56%, color L* 23.26, color a* 6.62, color b* 7.54, has a yellow color, distinctive aroma of brown rice, crunchy texture, and savory taste.

Abstract

This study aims to analyse the effect of aluminium foil packaging variation on the quality of kepok banana chips based on the parameters of moisture content, ash content, free fatty acid, colour, texture, and organoleptic test. The two types of packaging used were Full Aluminium Foil (0.3 mm) and Plastic Combination Aluminium Foil (0.2 mm), with a product shelf life of 30 days. Quality parameters were tested using moisture content, ash content, free fatty acids and sensory analysis, including colour and texture. The results showed that the packaging variation had no significant effect on moisture content, ash content, colour, and texture, but had a significant effect on free fatty acid content. The kepok banana chips produced did not meet the standard of fruit chips, both in terms of moisture content, ash content, and free fatty acids. However, the assessment by semi-trained panelists showed preference for the kepok banana chips based on colour and texture.
