Objectives: The purpose of this study was to develop new meal planning tools for a nutritionally balanced diet. Methods: Based on the food exchange list for diabetes, we adjusted the food group classification system to reflect the suggested nutritional factors for chronic disease prevention and health promotion. We developed a nutritionally balanced dietary profile for adults and compared it with the dietary reference intakes for Koreans (KDRIs) and the food pattern recommended by the Korean Diabetes Association. Results: The newly developed menu planning tools are the LOHAS food exchange table and the LOHAS food pattern. Our recommended daily 1,800 kcal dietary composition for adults is as follows: The carbohydrate food group consists of 4 'whole grains', 3 'refined grains', 2 'sugars', 9 'vegetables', 3 'starchy vegetables', 2 'fruits' and 1 'high sugar fruits'. The protein food group includes 3 'plant protein foods', 3 'animal protein foods (low-fat)', and 1 'animal protein foods (high-fat)'. The fat food group consists of 2 'oils and nuts' and 1 'solid fats'. The total number of calories is estimated at 1,840 kcal and the energy ratio is 62% carbohydrate, 18% protein, 20% fat, 6.8% saturated fat and 13.2% sugars. Using the LOHAS food exchange table, it is possible to estimate values of saturated fat, unsaturated fat, dietary fiber, and sugars besides carbohydrate, protein and fat. It is also possible to compose a dietary design considering carbohydrate, sugars, saturated fat and dietary fiber. The LOHAS food pattern provides benefits for the management of both institutional food services and individual meals, as it can help reduce the levels of saturated fat and sugar intake and help develop healthy meals rich in unsaturated fats and dietary fiber. Conclusions: The LOHAS food exchange table and LOHAS food pattern are expected to be practical tools for designing and evaluating nutritionally balanced diets.

Today's food technologist is receiving increasingly pointed directions in the “selection of”and often “minimum amounts of”ingredients to use in the development of new food products. This increasing emphasis by marketing on “label”claims is real and gaining momentum in most market places. Thus, the development of functional foods that are providing customers with new and distinct nutritional choices. The driving force for the increased direction of the food technologist is that many governments are now allowing health related label claims on food products. These health claims are a result of very clearly and focused research that shows known nutritional benefits. The regulatory environment is well focused on the results of this peer reviewed research. In the USA, FDA has allowed several opportunities for health claims including fiber, soy protein and choline. This presentation will focus on only two of many functional ingredient options-the soy proteins and lecithin(choline).

This review focuses on the enhanced functional characteristics of enzymatic hydrolysates of whey proteins (WPHs) in food applications compared to intact whey proteins (WPs). WPs are applied in foods as whey protein concentrates (WPCs), whey protein isolates (WPIs), and WPHs. WPs are byproducts of cheese production, used in a wide range of food applications due to their nutritional validity, functional activities, and cost effectiveness. Enzymatic hydrolysis yields improved functional and nutritional benefits in contrast to heat denaturation or native applications. WPHs improve solubility over a wide range of pH, create viscosity through water binding, and promote cohesion, adhesion, and elasticity. WPHs form stronger but more flexible edible films than WPC or WPI. WPHs enhance emulsification, bind fat, and facilitate whipping, compared to intact WPs. Extensive hydrolyzed WPHs with proper heat applications are the best emulsifiers and addition of polysaccharides improves the emulsification ability of WPHs. Also, WPHs improve the sensorial properties like color, flavor, and texture but impart a bitter taste in case where extensive hydrolysis (degree of hydrolysis greater than 8%). It is important to consider the type of enzyme, hydrolysis conditions, and WPHs production method based on the nature of food application.

The effects of various NaCl levels (0, 0.3, and 0.6 M) and pH values (pH 5.0, 5.5, 6.0, and 6.5) on the emulsifying and gelling properties of pork myofibrillar protein (MP) were assessed. The emulsion stability index (ESI), emulsifying activity index (EAI), and creaming index were measured at a 1:20 ratio of MP to corn oil. The EAI and ESI of pork MP showed maximum values at pHs 6.0 and 6.5 and at 0.3 M NaCl, resulting in better emulsion properties. Additionally, the cooking yield (CY) and gel strength (GS) of emulsified MP gel were measured at an MP: corn oil ratio of 1: 2; GS increased with increasing levels of salt. At 0.6 M NaCl, GS decreased with decreasing pH from 5.5 to 6.5. GS and gelling properties were optimal at pH 5.5 in 0.6 M salt. The highest CY was observed at 0.6 M NaCl, regardless of the pH value. However, increasing pH increased CY at salt levels of 0 and 0.3 M. These results indicate that NaCl and pH profoundly affected the emulsified MP system. Future work will be conducted on the rheological properties of the pork emulsified system as affected by adding non-meat protein.

This study was designed to evaluate the nutritional status and dietary problems of obese elementary students consuming unbalanced diets. Blood parameters, body-image perceptions, taste preferences, and nutrient intakes of 40 obese elementary students with unbalanced diets were compared to those of 40 additional obese elementary students as a control. The averages for age, height, weight, and obesity index were 11.5 years, 142.0 cm, 51.0 kg, and 35.4% in the study group and 11.8 years, 144.0 cm, 53.5 kg, and 36.3% in the control group, respectively. The major disliked foods by the students in the study group were vegetables (65%) particularly Kimchi (15%), as well as fish(15%), and pulses (10%). Mean serum cholesterol, blood glucose, GOT/GPT, and hemoglobin levels were 175.1 mg/dL, 89.2 mg/dL, 24.1/18.9 IU/L, and 14.3 g/dL in the study group and 182.8 mg/dL, 91.3 mg/dL, 28.3/33.9 IU/L, and 14.7 g/dL, in the control group, respectively. Approximately 60${\sim}$80% of the subjects responded that they eat a meal everyday, and the remainder skipped at least one meal. The preference for salty tasting foods was significantly lower in the study group, but the preference for hot tasting food was higher as compared to the obese control group(p<0.05, p<0.05). The daily energy intakes of the study and control groups were 1,768.3 kcal and 1,572.7 kcal, respectively, but there was no significant differences between them. Daily intakes of animal protein, fat, animal fat, and vitamin $B_2$ were significantly higher in the study group than in the control group. In conclusion, this study found that obese children consuming unbalanced diets strongly disliked vegetables, particularly Kimchi, as well as hot tasting foods; however, they preferred salty foods. Daily intakes of animal protein and fat were higher in the study group as compared to obese children not consuming unbalanced diets.

The level of fat and salt can affect the product quality and storage stability of processed meats. Additionally, consumers' demands require dietary guidelines for developing low-fat/salt functional foods. Microbial transglutaminase (MTGase), which enhances textural properties by catalyzing protein-protein cross-linkages, was introduced to develop healthier lowfat/salt meat products. The potential possibilities of low-fat/salt processed meats were reviewed under optimal conditions for functional ingredients from several previous studies. The addition of non-meat protein (e.g. sodium caseinate and soy protein isolates), hydrocolloids (e. g. konjac flour, carrageenan, and alginates), and MTGase alone or in combination with other functional ingredients improved textural and sensory properties similar to those of regularly processed meats. When MTGase was combined with hydrocolloids (konjac flour or sodium alginate) or other functional ingredients, gelling properties of meat protein were improved even at a low salt level. Based on these reviews, functional ingredients combined with new processing technologies could be incorporated into processed meats to improve the functionality of various low-fat/salt meat products.

Consumer demand for products with health benefits and natural ingredients is significant for the expansion of functional foods. Edible films and coatings are an excellent way to diversify the market for functional foods and as substitutes for the prevailing packaging and products. Incorporation of whey protein (WP) and its active ingredients into edible films and coatings is a promising technique that can be applied to various food products. Numerous combinations can be used on an industrial scale depending on the purpose, product, nature of the film, type of active ingredient, and type of inclusions. In this review, we describe several characteristics of edible WP films and coatings used as novel packaging materials. WP-based packaging can play a beneficial role in sustainability because of the option of recycling materials rather than incinerating, as in synthetic laminates, because of the use of natural byproducts from the food industry as raw materials. However, cost-effectiveness is a driving force against industrial setbacks in current and future WP processing developments. The industrial application of this new technology depends on further scientific research aimed at identifying the mechanism of film formation to improve the performance of both the process and product. Furthermore, research such as consumer studies and long-term toxicity assessments are required to obtain significant market shares.

The dietary vitamin $B_6$ intake of 218 Korean young women (aged 20-26y), who had no health problems, and their sources were estimated using a modified Korean vitamin $B_6$ database. The average daily vitamin $B_6$ intake was 0.987 mg for the subjects. About 87.2% of the subjects consumed less than the Korean Recommended Dietary Allowance (RDA) of vitamin $B_6$. The average ratio of vitamin $B_6$ intake to daily protein intake was 0.014 mg/g protein, and approximately 91% of subjects consumed 〈 0.02 mg/g protein. Vitamin $B_6$ intake was significantly (p〈.01 -p〈.001) positively correlated to the intakes of all other nutrients. Between animal and vegetable protein, animal protein had a stronger positive correlation with vitamin $B_6$. Major dietary sources of vitamin $B_6$, the top 10 foods provided nearly 64% of total vitamin $B_6$, and dietary contributors of vitamin $B_6$ for Koreans are less varied than those for Americans.

Milk proteins, such as casein and whey protein, exhibit significant potential as natural emulsifiers for the preparation and stabilization of emulsion-based delivery systems. This can be attributed to their unique functional properties, such as the amphiphilic nature, GRAS (generally recognized as safe) status, high nutritional value, and viscoelastic film-forming ability around oil droplets. In addition, milk protein has been used as a coating material in emulsion-based delivery systems to protect bioactive compounds during food processing and storage owing to its unique functional properties. These properties include the ability to bind lipophilic bioactive compounds and antioxidant activity. In this review, we present the use of milk proteins as emulsifiers for the formation of emulsions and food applications of milk protein-stabilized emulsion delivery systems.
