The market sales of premium ice cream have paralleled the growth in consumer desire for rich flavor and taste. Storage temperature is a major consideration in preserving the quality attributes of premium ice cream products for both the manufacturer and retailers during prolonged storage. We investigated the effect of storage temperature (−18℃, −30℃, −50℃, and −70℃) and storage times, up to 52 wk, on the quality attributes of premium ice cream. Quality attributes tested included ice crystal size, air cell size, melting resistance, and color. Ice crystal size increased from 40.3 µm to 100.1 µm after 52 wk of storage at −18℃. When ice cream samples were stored at −50℃ or −70℃, ice crystal size slightly increased from 40.3 µm to 57-58 µm. Initial air cell size increased from 37.1 µm to 87.7 µm after storage at −18℃ for 52 wk. However, for storage temperatures of −50℃ and −70℃, air cell size increased only slightly from 37.1 µm to 46-47 µm. Low storage temperature (−50℃ and −70℃) resulted in better melt resistance and minimized color changes in comparison to high temperature storage (−18℃ and −30℃). In our study, quality changes in premium ice cream were gradually minimized according to decrease in storage temperature up to−50℃. No significant beneficial effect of −70℃ storage was found in quality attributes. In the scope of our experiment, we recommend a storage temperature of −50℃ to preserve the quality attributes of premium ice cream.

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.

Purpose: The purpose of this study is to analyze current trends in the Korean ice cream industry and determine how these trends affect the competitiveness of each ice cream company. Method: This study was conducted by reviewing existing related literature and collecting and analyzing data from news articles, corporate reports, and existing researchers' studies related to the ice cream industry. Results: The Korean ice cream industry is growing and developing through the collaboration of fun marketing with taste, quality, and fun elements, and the young MZ generation can be said to be the main customer base. In terms of quality, premium ice cream made with high-quality domestic ingredients has recently been gaining popularity, and ice cream with reduced fat and sugar, such as plant-based substitutes, is also gaining popularity among consumers. Conclusions and Implications: The results of this study highlight the need for continued innovation in the Korean ice cream industry. The industry must also capitalize on the growth of online sales and the global appeal of Korean pop culture. Sustainability efforts, technology adoption, and strategic collaboration are key drivers for future industry success, and social media engagement must be integrated into marketing strategies to increase brand awareness and consumer loyalty.

본 연구에서는 시중에 유통되는 일반 '아이스크림' 22개 제품과 프리미엄 '아이스크림' 10개 제품, '아이스밀크' 22개 제품, '샤베트' 4개 제품, '비유지방 아이스크림' 11개 제품과 '빙과류'인 '비유제품 아이스크림' 5개 제품을 수집하여, 이들 아이스크림 제품류에서 추출한 지방의 조지방 함량과 지방산조성을 분석하였다. 일반 '아이스크림', 프리미엄 '아이스크림', '아이스밀크'에는 지방이 각각 $5{\sim}11%,\;13{\sim}17%,\;2{\sim}10%$ 함유되어 있었다. '샤베트', '비유지방 아이스크림', '비유제품 아이스크림'에는 지방이 각각 $2{\sim}7%,\;4{\sim}11%,\;1{\sim}2%$함유되어 있었다. 일반 '아이스크림' 22개 제품 중 14개 제품, 프리미엄 '아이스크림' 10개 모든 제품, '아이스밀크' 22개 제품 중 11개 제품에서 분리한 지방에는 포화지방산이 $63{\sim}75%$, 트랜스지방산이 $2{\sim}5%$ 함유되어 있었는데, 이는 우유나 버터에 있는 지방과 유사한 조성이었다. 그러나 일반 '아이스크림' 8개 제품과 '아이스밀크' 11개 제품에서 추출한 지방에는 lauric acid가 각각 $11{\sim}28%$와 $11{\sim}34%$ 함유되어 있었는데, 이는 우유나 버터의 지방을 조성하고 있는 lauric acid 함량보다 3배 이상 높은 값으로서 유지방만을 지방원료로 사용하였다고 보기는 어렵다. 이들 19개 제품 중에서 5개 제품에서만 유지방 이외에 '야자유'나 '정제가공유지'를 사용하였다고 표시하였다. '샤베트', '비유지방 아이스크림', '비유제품 아이스크림'에서 분리한 지방에는 포화지방산이 각각 $81{\sim}92%,\;76{\sim}99%,\;84{\sim}99%$ 함유되어 있었으며, lauric acid가 각각 $33{\sim}34%,\;17{\sim}45%,\;27{\sim}46%$로써 가장 많은 부분을 차지하고 있었다.
