Capsaicinoid content, among other factors, affects the perception of spiciness of commercial kimchi. Here, we investigated whether the physicochemical properties of kimchi affect the spicy taste of capsaicinoids perceived by the tasting. High-performance liquid chromatography (HPLC) was used to evaluate the capsaicinoid content (mg/kg) of thirteen types of commercial kimchi. The physicochemical properties such as pH, titratable acidity, salinity, free sugar content, and free amino acid content were evaluated, and the spicy strength grade was determined by selected panel to analyze the correlation between these properties. Panels were trained for 48 h prior to actual evaluation by panel leaders trained for over 1000 h according to the SpectrumTM method. Partial correlation analysis was performed to examine other candidate parameters that interfere with the sensory evaluation of spiciness and capsaicinoid content. To express the specific variance after eliminating the effects of other variables, partial correlations were used to estimate the relationships between two variables. We observed a strong correlation between spiciness intensity ratings and capsaicinoid content, with a Pearson’s correlation coefficient of 0.78 at p ≤ 0.001. However, other specific variables may have influenced the relationship between spiciness intensity and total capsaicinoid content. Partial correlation analysis indicated that the free sugar content most strongly affected the relationship between spiciness intensity and capsaicinoid content, showing the largest first-order partial correlation coefficient (rxy/z: 0.091, p ≤ 0.01).

Honey is a natural liquid that is commonly used as an addition to food or drinks and has properties thatare believed to increase endurance and cure various diseases. Honey has different characteristics basedon taste, aroma, color. This can not be separated from the physico-chemical content of honey. Highwater content in honey can reduce the shelf life of honey because it can cause fermentation by yeast.So, in this study, cassava honey was processed using a vacuum cooling device designed by Mr. AnangLastriyanto from Brawijaya University with the aim of seeing the effect of changes in honey quality onlow temperature heating with vacuum pressure to reduce the water content of honey. After processingwith a vacuum cooling device, the reducing sugar content, moisture content and total dissolved solidsin the cassava honey are tested to show the effect of using a vacuum cooling device. Real honey has areducing sugar content of 52.43% and after vacuum cooling it becomes 55.06%. The water content ofreal honey is 27.2% to 11.22 after the vacuum cooling process. The total dissolved solids of the originalhoney was 68.75% Brix to 79.5% Brix after vacuum cooling.

ABSTRACT: This study identified physiological and biochemical changes in ‘Fuyu’ persimmon buds during dormancy. Branches were collected between March and August 2015. Dormancy was evaluated by biological testing of isolated node cuttings at 25 °C and a photoperiod of 16 h. The variables analyzed were water content; reducing sugar content; respiratory activity; activity of superoxide dismutase (SOD), catalase (CAT), ascorbate peroxidase (APX), guaiacol peroxidase (POD) and polyphenol oxidase (PPO) enzymes; hydrogen peroxide content (H2O2) and lipid peroxidation. At the end of March 2015, the plants were already dormant, and the leaves and fruits present indicated a paradormancy effect. Induction of endodormancy may have occurred in June 2015, when chilling hours (CH) below 7.2 °C and higher CH below 12 °C began to accumulate, which coincided with the period in which there was a decrease in water content and respiratory activity, an increase in reducing sugars, a decrease in SOD, CAT, APX and PPO and an increase in H2O2. After an accumulation of 553 CH below 12 °C, the budburst capacity increased, and the buds presented increased water content, decreased reducing sugars content, increased respiratory activity, low activity in SOD, CAT, APX and POD and high levels of H2O2.
