This study presents the quality characteristics of blueberry bread. Blueberry fruit powder was added to bread dough at various concentrations ranging from 3~9%, after which physicochemical properties of dough and bread containing blueberry fruit powder were determined. The pH, loaf volume, specific loaf volume, dough volume and baking loss decreased with increasing amount of blueberry fruit powder in bread, whereas loaf weight and hardness were reduced. In particular, hardness appeared to be 1.98 times higher in the control without blueberry powder compared to the bread containing 9% blueberry powder. For color, increasing the amount of blueberry fruit powder reduced L and b values, whereas a value was increased. In the sensory evaluation, the highest overall preference score was observed in bread containing 6% blueberry powder, whereas the lowest score was observed in bread with 9% blueberry powder. From these results, blueberry bread with good acceptability has an optimum blueberry powder concentration of 6%.

This study investigated the physicochemical and sensory characteristics of rice pound cake prepared with various amounts of blueberry powder. The weight of rice pound cakes with additions of 2~8% blueberry powder increased from 418.58 to 420.50 g. The volume and specific loaf volume of rice pound cakes prepared by adding blueberry powder were lower than those of the control. The baking loss rate for the control was 7.72% and that of rice pound cakes prepared by adding blueberry powder decreased by 6.98~6.56%. The moisture contents of rice pound cakes added with blueberry powder were higher than the control. The pH levels for rice pound cakes prepared with blueberry powder ranged between 6.47 and 7.58 and that of the control was 8.11. The microstructural observation by scanning electron microscopy (SEM) showed well developed air cells of control. DPPH radical scavenging activity of the control group was 13.6%, whereas pound cakes prepared by adding blueberry powder ranged from 35.2~78.8%. The "a" value of redness was increased, but L and b value were decreased significantly by additions of blueberry powder. The full textural properties of rice pound cakes were being significantly increased by additions of blueberry powder. Sensory evaluation scores in terms of appearance, flavor, taste, texture and overall preference for pound cakes showed that 4~6% of substituted sample groups were higher than those of others. The results of this study suggest that additions of 4~6% blueberry powder was the best substitution ratio for rice pound cakes.

The purpose of this study was to promote consumption of rice through production of jeungpyun added with blueberry attracting attention as a functional food material and to develop a functional blueberry supplement suited to the preference of Westernized consumers. For that pupose, we performed physicochemical quality test and sensory test after preparing the jeungpyun added with blueberry powder based on a ratio of 1%, 2%, 3%, and 4% of rice flour. The results of this experiment can be summarized as follows. When the addition of blueberry powder increased, the moisture content in jeungpyun decreased, but there was no significant difference between the samples. The lightness and the yellowness related to chromaticity decreased and redness increased when the addition of blueberry powder increased. The pH of the dough in jeungpyun increased significantly (p<0.001) when addition of blueberry powder increased. As the fermentation progressed, the pH tended to decline. The volume of dough decreased when addition of blueberry powder increased. The volume was the highest after the first fermentation, and decreased after the second fermentation. Viscosity decreased significantly as the addition of blueberry powder increased, and increased as fermentation time increased, and decreased after the third fermentation. A test was conducted to determine difference in characteristics, and the results showed that the color intensity, cell uniformity, blueberry flavor and sweetness were strong when the addition of blueberry powder increased. The results of preference test showed that JB3 containing 3% blueberry powder had the best appearance, flavor and overall acceptance.

The blueberry eco-friendly farming requires the soil condition of pH 4.2 ~ 5.2 and high in organic matters for stable growth. Most of soil types of blueberry-growing land in Korea, however, belongs to alkaline soils with low organic matter content. As a result, the eco-friendly blueberry growers use peat moss and sulfur powder heavily to improve the soil condition, but the guideline on the effective use of organic materials was not established yet. Therefore, this sturdy was performed to investigate the effect of increasing soil acidity and organic matters by using organic materials. Among 5 organic materials, the pH of soil was lowest in degradable sulfur + bentonite (pH 4.1) and followed by Peat moss+Chaff+Pine Needlesmixtures(pH 4.5), OrganicAcid +vinegar (pH 4.7), Sulfur powder (pH 4.8), Temperature response Elutioner (pH 5.2). The soil organic matter content were increased in the following order: Peat moss+Chaff+Pine Needlesmixtures (8.4%) > degradable sulfur + bentonite (7.8%) > Organic Acid + vinegar (7.2%) > Sulfur powder ${\fallingdotseq}$ Temperature response Elutioner (6.3%). Although different in the degree, all organic materials treated was recognized a good material for improving soil pH and organic matter content. The plant height and stem diameter of blueberry were no clear difference among 5 organic materials. Another study was carried out to investigate amending soils with organic matter by soil mulching with pine needles for soil surface management in blueberry organic cultivation. The effect of increasing the soil pH by pine needle mulching in blueberry eco-friendly farming was recognized in four test fields. Pine needle mulching for soil surface management in blueberry appeared several advantages, such as improving of soil pH and organic matter content. Therefore, pineneedle mulching in blueberry organic farming is considered as the most efficient means of mulching cultivation for amending soil pH, weed suppression and moisture conservation among mulching materials.

The objective of this study was to determine effects of humic acid (HA) and blueberry leaf powder (BLP) supplementation in pig feed on productivity, blood profiles, and meat quality characteristics of longissimus muscle. The experimental design included six treatments: 1) CON, no addition; 2) T1, BLP 0.1%; 3) T2, BLP 0.2%; 4) T3, humic acid 2%; 5) T4: humic acid 2%+BLP 0.1%; and 6) T5: humic acid 2%+BLP 0.2%. HA and BLP supplementation in pig feed significantly increased average daily feed intake (ADFI) values (p<0.05). HA supplementation in pig feed had beneficial effects in lipid profiles without altering feed efficiency rate (FER). HA and BLP co-supplementation in pig feed decreased pH in longissimus thoracis (p<0.05). In addition, sensory characteristics were enhanced when pig feed was supplemented with HA and BLP without causing adverse effects in meat quality. Taken together, addition of HA and BLP in pig feed may produce functional meat products.
