A supply of pure, intact oil bodies is essential for carrying out morphological and biochemical studies of these plant organelles and exploring their application. Preparation requires a carefully controlled breakage of plant cells, followed by separation of the oil bodies from cytoplasm and cell debris. This paper focuses on the recovery and characterisation of oil bodies from pecan nuts where no work has been published to date. The results showed that soaking softens the nut tissue and appears to reduce the damage to oil bodies during grinding and centrifugal force must be carefully selected to minimise oil bodies damage on recovery. A 24 h soaking time coupled with a 5500 RCF recovery force allows for the recovery of intact pecan nut oil bodies.

The objectives of the study were (1) to know there was or no interaction between soaking time in bay leaf and type of carcass to the physical quality of broiler meat; (2) To know the duration of optimum immersion for the physical quality of the muscles of the breast and thighs. This research was arranged using Completely Randomized Design (RAL) with factorial pattern. The first factor is the length of meat immersion in bay leaf solution, namely: P0: control; P1 (20 minutes); P2 (40 minutes); P3 (60 minutes). While the second factor is a piece of carcass, namely: K1 (thigh) and K2 (chest). Each treatment was repeated 3 times. The research variables were pH of meat, WHC, and cooking loss. The data obtained were proceed to variance analyze and further tested by BNT  Test for length of  immersion and Tukey test for carcass type at 5% level of significant. The results showed that there was no interaction (P>0,05) between soaking time and carcass cut. The duration of immersion had no significant (P>0,05) effect on pH, WHC, and cooking loss. Carcasses cut of thight and breast have a significant effect (P<0,05) on pH and cooking loss, but are not significant (P>0,05) for WHC. The pH value of the thigh meat is significantly (P<0,5) higher than the breast, but the cooking loss is lower. Keywords :  Bay Leaf, Breast, Thight, Broiler, Physical Quality

THE EFFECT OF MARINATING TIME USING CUKA SAGUER ON PHYSICAL QUALITY INCREASING OF ENTOK MEAT (Chairina Moschata). This study aims to determine of physical quality of entok meat after marinating with cuka saguer. Cuka saguer using to soak meat in this research was obtained from fermentated yield of fluid from enau tree. The marinated meat in this research was entok meat. This experiment was arranged in a completely randomized design consisted of five treatments as followed R0 entok meat was without marinated , R1 entok meat was marinated for 20 minutes, R2 entok meat was marinated for 40 minutes, R3 entok meat was marinated for 60 minutes, R4 entok meat was marinated for 80 minutes and each treatment was conducted four times replication. If occur significant in analysis of variance so the average comparing was followed by DMRT test. The result showed The marinated entok meat using cuka saguer was significantly on pH and water holding capacity (WHC), while texture of meat no significant. In conclusion, the soaking time for 20 minutes with cuka saguer can be used to soak entok meat because able to maintain texture of meat and to increase WHC at the condition of pH normal.   Keywords: entok meat, cuka saguer, physical quality of meat

The use of colorants in the dried noodle manufactures is an effort of product diversification. Besides of being used as a natural coloring agent, this peel extract is also used to improve nutritional value of the expected product. The purpose of this study was to determine the effect of red dragon fruit peel extract on the physical quality of dried noodle.  The study was conducted by using Completely Randomized Design (CRD) method with one factor, namely concentration of red dragon fruit peel extract (N1 = 10 ml, N2 = 15 ml, N3 = 20 ml, N4 = 25 ml, N5 = 30 ml).  The observations of its physical quality consisted of water absorption, solid loss during cooking, and organoleptic tests (aroma and color).  The best quality of dried noodle was obtained by using 30 ml red dragon fruit peel extract (N5) with physical properties, namely DSA levels of 351.92%, solid loss during cooking 4.78%, aroma 3.79 (like) and color 3.89 (like).

Turmeric (Curcuma longa L) in Indonesia is widely known as a herbal medicinal plant, food coloring, and food flavoring. The high water content of turmeric will shorten the storage time and the quality of the ingredients. The need for drying which is the process of removing the moisture content of the material with the aim of prolonging the shelf life. The use of the foam-mat drying method with the addition of adhesives aims to speed up the drying process and maintain the quality of a material. The result of drying turmeric obtained is turmeric powder product. This study used a completely randomized design (CRD) with two factors, namely the variation of the microwave oven power and the composition of the developer agent (ovalet). The research procedure was divided into two stages, namely the manufacture of powder and continued with the measurement of physical quality. The stages of making powder begin with the preparation of raw materials, stripping, size reduction, addition of developer, drying, then grinding. The second stage is measuring physical quality, namely fineness modulus, average grain size, powder moisture content, color, water absorption, oil absorption, and bulk density. The power variations used are 420 watts, 535 watts, and 680 watts, while the composition of the developer is 1%, 2%, and 4%. Data analysis using two-way ANOVA statistical test with two factors that affect the variation of power and composition of the developer (ovalet). FM values ​​ranged from 0.364 – 1.576, D values ​​ranged from 0.005 – 0.0012 mm, final moisture content values ​​ranged from 7.60 – 9.59%, powder moisture content values ​​ranged from 9.47 – 11.43%ww , L values ​​ranged from 61.46 – 65.96, a values ​​ranged from 13.54 – 16.05, b values ​​ranged from 48.21 – 52.42, DSA values ​​ranged from 2.78 – 3.54 ml/ g, DSM values ​​ranged from 1.22 – 1.60 ml/g, and DC values ​​ranged from 0.38 – 0.44 g/cm3. The combination treatment of drying power with developer is influenced by the drying power of the parameters, namely the value of moisture content, fineness modulus, average grain size, brightness level, redness level, yellowness level, oil absorption, water absorption, and bulk density. While the developer affects the finenes modulus, average grain size, yellowness level, and bulk density.

The response surface methodology was used to optimize the hydrothermal processing conditions based on the rice quality parameters of the Rong Youhua Zhan rice variety (Indica). The effect of soaking temperature (29.77, 40, 55, 70, and 80.23°C), soaking time (67.55, 90, 120, 150, and 170.45 min), and steaming time (1.59, 5, 10, 15, and 18.41 min), each tested at five levels, on percentage of head rice yield (HRY), hardness, cooking time, lightness, and color were determined, with R2 values of 0.96, 0.94, 0.90, 0.88, and 0.94, respectively. HRY, hardness, cooking time, and color increased with process severity while lightness decreased, although HRY decreased after reaching a maximum. The predicted optimum soaking temperature, soaking time, and steaming time were 69.88°C, 150 min, and 6.73 min, respectively, and the predicted HRY, hardness, cooking time, lightness, and color under these conditions were 73.43%, 29.95 N, 32.14 min, 83.03 min, and 12.24 min, respectively, with a composite desirability of 0.9658. The parboiling industry could use the findings of the current study to obtain the desired quality of parboiled rice. This manuscript will be helpful for researchers working on commercializing parboiled rice processes in China as well as in other countries.
