  • This study was designed to investigate the amount of free sugar according to each beverage category in coffee and beverage stores. The groups were categorized as 15 groups based on the kind of beverage material. The beverage groups contributing to total sugar per 100 mL were milk + syrup or powder, hot (12.9 g), ade (12.6 g), milk + syrup or powder + crushed ice (11.9 g), and espresso shot + milk + syrup + crushed ice (11.4 g). The beverage groups contributing to free sugar per 100 mL were ade (12.6 g), milk + syrup or powder + crushed ice (10.8 g), espresso shot + milk + syrup + crushed ice (10.3 g), and milk + syrup or powder, hot (9.7 g). The beverage groups contributing to total sugar (energy) per portion size were milk + syrup or powder + crushed ice 56.6 g (332.3 kcal), espresso shot + milk + syrup + crushed ice 49.3 g (333.4 kcal), milk + syrup or powder, hot 46.3 g (372.1 kcal), and milk + syrup or powder, ice 38.1 g (325.9 kcal). The beverage groups contributing to free sugar per portion size were milk + syrup or powder + crushed ice 51.2 g, espresso shot + milk + syrup + crushed ice 44.9 g, ade 37.1 g, milk + syrup or powder, hot 34.6 g, and milk + syrup or powder, ice 30.1 g. The percent of average free sugar per portion size of the WHO recommendation (free sugars <10% of total energy; <50 g/2,000 kcal) was milk + syrup or powder + crushed ice 102.4%, espresso shot + milk + syrup + crushed ice 89.8%, ade 74.1%, and milk + syrup or powder, hot 69.2%. The proportion of beverage in excess of WHO recommendation per portion size was 14.6% in espresso shot + milk + syrup + crushed ice, 22.7% in ade, and 10.9% in milk + syrup or powder, hot. Therefore, in coffee and beverage stores, menu development with reduced sugar content is needed, and nutrition information should be provided through sugar nutrition labeling.

  • Freeze concentration of milk was carried out through the controlled recrystallization of ice in a multi-stage freeze concentrator. Rheological characteristics of ice slurries were analyzed to determine efficient concentration levels for the freeze concentration process. It was determined that efficient concentration level was 17% of total solids in the first and 27% in the second stage. Physicochemical properties were compared between freeze concentrated and evaporated milk. Freeze concentrated milk was more similar in color appearance to control milk than was evaporated milk. pH significantly decreased in evaporated milk than in freeze concentrated milk. pH of freeze concentrated milk resulted in similar value to control. These results indicated the advantages of freeze concentration as a non-thermal milk processing technology in terms of physicochemical properties. Consequently, we investigated the influence of ice recrystallization on the rheological characteristics of ice slurries and physicochemical properties of freeze concentrated milk.

  • The purpose of this study was to investigate not only quality characteristics such as overrun, meltdown and sensory evaluation of oligosaccharide-supplemented soy ice cream but also physiological effects of ice cream with soy and/or oligosaccharide on blood sugar and lipid profile in streptozotocin-induced diabetic rats. Powder of parched soybean was added at $7.6\%$ replacing skimmed milk and cream, soybean oil at $7.6\%$ replacing milk oil in cream, and fructooli-gosaccharide at $9.5\%$ replacing sucrose on weight basis. Five kinds of ice cream were prepared: MMS (skimmed milk, milk oil, sucrose), MMO (skimmed milk, milk oil, oligosaccharide), SSS (soybean, soybean oil, sucrose), SSO (soybean, soybean oil, oligosaccharide), and BSO (black soybean, soybean oil, oligosaccharide). Overrun and meltdown of soy ice cream were significantly lower than those of milk ice cream. Scores of sensory evaluation especially in mouth feel and melting feel in mouth were lower in soy ice cream. Freeze-dried ice cream was supplemented to AIN93-based diets at $30\%$(w/w). Sprague-Dawley male rats with diabetes induced by injecting streptozotocin were fed experimental diets for 4 weeks. Plasma glucose level was significantly lowered in SSO group compared with MMS group. Plasma insulin levels of MMO and SSO groups were not significantly different from that of normal group, while those of MMS and SSO group were significantly lower than normal group. Plasma cholesterol was decreased in groups fed ice cream supplemented either soybean or fructooligosaccharide compared to MMS group. HDL-cholesterol level was elevated and triglyceride was decreased significantly in MMO group compared to MMS group. LDL-cholesterol levels of SSS and BSO groups and liver triglyceride level of SSO group were significantly lower compared to MMS group. In conclusion, oligosaccharide-supplemented soy ice cream lowered blood sugar, and ice cream supplemented with soybean and/or oligosaccharide improved lipid profile in diabetic rats.

  • The objective of the study was to analyze the contents and fatty acid compositions in the extracted fats from selected commercial ice creams and ice cream-related products. Seventy four ice creams and ice cream-related products were collected from local stores: 22 regular 'ice creams', 10 premium 'ice creams', 22 'ice milks', 4 'sherbets', 11 'non-milk-fat ice creams' and 5 'non-milk product ice creams'. Contents and fatty acid compositions of the fats in the ice creams and ice cream-related products were analyzed. Fat contents in regular 'ice creams', premium 'ice creams' and 'ice milks' were $5{\sim}11%,\;13{\sim}17%\;and\;2{\sim}10%$, respectively. 'Sherbets', 'non-milk-fat ice creams' and 'non-milk product ice creams' contained $2{\sim}7%,\;4{\sim}11%\;and\;1{\sim}2%$ fats, respectively. Fats extracted from 14 regular 'ice creams', all of the premium 'ice creams' and 11 'ice milks' contained $63{\sim}75%$ saturated fatty acids and $2{\sim}5%$ trans fatty acids. Their fatty acid compositions were similar to those in milks and butter. However, fats from 8 regular 'ice creams' and 11 'ice milks' contained $11{\sim}28%\;and\;11{\sim}34%$ lauric acid, respectively. Since these levels of lauric acid were 3 times more than in milk or butter, other fats along with milk fat might be used for manufacturing these' ice creams' and 'ice milks'. Out of these 19 products, only 5 products were labelled as 'coconut oil' or 'refined oil' as well as milk fat being used. Fats extracted from 'sherbets', 'non-milk-fat ice creams' and 'non-milk product ice creams' contained $81{\sim}92%,\;76{\sim}99%\;and\;84{\sim}99%$ saturated fatty acids, respectively. Lauric acid was the most abundant fatty acid in the fats of these products, being $33{\sim}34%,\;17{\sim}45%\;and\;27{\sim}46%$ of the total fatty acids, respectively.

  • Freeze concentration of milk was carried out thorough the controlled recrystallization of ice in a multi-stage freeze concentrator. Artificial temperature control was used to induce ice recrystallization via a heat and cold shock process. In each stage of freeze concentration, the recrystallization time was fixed at 1, 2, 4, and 8 hr to compare the solute concentrate, yield, Brix, ice crystal size, and freezing point at each experimental condition. Higher concentrations of milk solids were seen with increased durations of recrystallization time, and a maximum total solids in the final product of 32.7% was obtained with a ripening time of 8 hr in a second stage process. Milk solid yield decreased according to the solute concentration and recrystallization time. The results of Brix and ice crystal size showed a positive correlation with recrystallizaiton time. These results suggest the possibility of freeze concentration being of practical use in the dairy industry.

  • This study was performed to compare the performance of Sanita-Kun dry medium culture plate with those of traditional culture medium and Petrifilm dry medium culture plate for the enumeration of the mesophilic aerobic bacteria in milk, ice cream, ham, and codfish fillet. Mesophilic aerobic bacteria were comparatively evaluated in milk, ice cream, ham, and codfish fillet using Sanita-Kun aerobic count (SAC), Petrifilm aerobic count (PAC), and traditional plate count agar (PCA) media. According to the results, all methods showed high correlations of 0.989~1.000 and no significant differences were observed for enumerating the mesophilic aerobic bacteria in the tested food products. SAC method was easier to perform and count colonies efficiently as compared to the PCA and PAC methods. Therefore, we concluded that the SAC method offers an acceptable alternative to the PCA and PAC methods for counting the mesophilic aerobic bacteria in milk, ice cream, ham, and codfish fillet products.

  • The purpose of this study was to investigate the nutrition knowledge, perception, and intake frequency of milk and milk products among middle school students as well as provide the basic data needed for increasing milk and milk product consumption. To achieve the purpose of this study, a survey with 385 students of four middle schools located in Chuncheon was conducted. The level of nutrition knowledge of milk and milk products in females was slightly higher than that in males (p<0.01). Flavored milk and ice cream were preferred the most in each category, and 'taste' influenced the selection of milk and milk products the most. The intake frequency of whole milk was the highest, and that of flavored milk was lowest among various milks. Ice cream showed the highest intake frequency while cheese showed the lowest among milk products. Male students showed higher intake frequency of milk and milk products. Groups having high level of nutrition knowledge showed the highest intake of whole milk, whereas groups having a low level of nutrition knowledge preferred processed milk, low fat or non-fat milk, and cheese the lowest.

  • The object of this study was to investigate the difference in physical and sensory properties of various premium ice creams. The physical properties of the various ice creams were compared by manufacturing brand. The water contents of the samples differed, with BR having the highest value at 60.5%, followed by NT and CS at 57.8% and 56.9%, respectively. The higher the water content, the lower Brix and milk fat contents in all samples. The density of the samples showed almost similar values in all samples (p>0.05). The viscosity of each ice cream had no effect on the water content in any of the brands. Before melting of the ice cream, the total color difference was dependent on the lightness, especially in the vanilla ice cream, owing to the reflection of light on the surface of the ice crystals. The CS product melted the fastest. In the sensory test, CS obtained a significantly higher sweetness intensity score but a lower score for color intensity, probably due to the smaller difference in total color, by which consumers might consider the color of CS as less intense. From this study, the cold chain system for ice cream distribution might be important to decide the physical properties although the concentration of milk fat is key factor in premium ice cream.

  • The purpose of this study is to investigate the effects of the ice-cream containing mulberry leaves on glucose levels in blood and on sensory characteristics. Mulberry leaves were treated with sodium hydrogencarbonate (NaHCO3) to remove the fresh green note out of dried mulberry powder with ball mill. The recovery rate of dried mulberry leaf powder was 28.9% from fresh mulberry leaves. The points of ice-cream with (treatment 2 : milk-fatty 23%) and without (treatment 7 : coconut butter 9.5%) milk-fatty in the sensory characteristics were 8.31 and 8.47, respectively, of 9.00 as a full point. The range of age of volunteers taken part in the glucose level test were 21∼25 years old. The glucose levels in blood were measured before and after taking up ice-cream. In case of ice-cream with vanilla, the glucose levels increased 27.8%, while those in the up take of ice-cream with mulberry powder decreased 1.6%. In conclusion, the present study has demonstrated that ice-cream containing mulberry leaf powder has an effect to decrease blood glucose levels after the application.

  • This study examines ice cream products with higher preference as dessert food using Tarak which is Korean traditional fermented milk (sherbet 1 kind, ice milk 2 kinds(IM-2, IM-4), ice cream 1 kind (IC-6)), and investigates the quality characteristics of each Tarak ice cream. For viscosity of the mix for Tarak ice creams, sherbet showed the lowest, and IC-6 showed the highest, significantly. For overrun, at 10 minutes, IC-6 with high milk fat content showed a higher value, and at the final 30 minutes, there was no significant difference among all samples. For melting point, IC-6 showed the highest and sherbet showed the lowest. For number of lactic acid bacteria, sherbet showed 7.32 Log CFU/g and IM-2, IM-4 and IM-6 showed 8.35~8.49 Log CFU/g, not showing significant difference. For sensory test of Tarak ice creams, IC-6 showed milk flavor highest, 4.10, and for sourness, sherbet showed 4.20 and IM-2 showed 4.10. For sweet taste, IC-6 showed the highest 5.05, and for bitter, IC-6 showed the lowest, 1.65. For the degree of creaminess, IC-6 was assessed significantly higher as 4.60 and body sense was also assessed higher as 5.05. For acceptance of appearance, taste, flavor and texture, IC-6 was assessed significantly higher than the other samples and for overall acceptability, IC-6 was assessed the highest at 5.15, sherbet showed 3.75, IM-2 showed 3.05 and IM-4 showed 2.50. This suggests that for Tarak ice creams, sensory preference of ice creams with high milk fat content or sherbet with non milk fat content is high.
