低温烹饪的特点及技术要点分析

随着科学技术的快速发展,低温烹饪这种健康、高效的烹调方法逐渐走进人们的生活。在保持食物特性的前提下,低温烹饪可以最大限度地保存食品的营养成分,同时可以大大减少烹调过程中有害物质的产生。本文以具体的食品材料低温烹饪为例,分析了低温烹饪的具体要点。     

浅谈烹饪过程中对食物营养素的保护

生活中的食物原料均含不同的营养素,烹饪将食材加工成色、香、味、形、质俱全的食物,利于人体消化吸收,保证身体的合理营养与健康。但食物经过烹饪加工后所含有营养素会有一定的改变,从而影响食物的营养价值。本文从烹饪过程食材营养流失、破坏等现象,就在烹饪过程中如何保护食物的营养素进行浅析。     

食品的化学性污染的危害及防治

食品在生产、加工、贮藏、运输和烹调等过程中会被有害物质污染,本文主要讲述了食品的化学性污染来源以及如何进行防治化学性污染。     

烹调工艺对菜肴营养成分的影响

随着社会的快速发展,人民生活水平得到了很大的提高,对于饮食的要求变得也越来越高。菜肴中的营养物质会受到烹调工艺的影响,合理、科学的烹饪是确保菜肴中各种营养成分的重要手段,本文针对不同的烹调工艺研究与分析菜肴营养成分的影响。     

烹饪方法对食物营养成分的影响探讨

良好的烹饪方法不仅可以使人们品尝到鲜美的食物,还可以让人们获得一定的营养,这对人们的身体健康具有重要的意义。但是错误的烹饪方法会大大降低食物的营养,导致人们无法从食物中获取相应的营养,从而导致食物的浪费。本文首先阐述了初加工对食物营养素的双重影响,然后分析了常用烹调方法对食物营养价值的影响,最后介绍了减少营养素损失的方法和措施。

当下快节奏的生活方式使得消费者寻求烹调耗时短的餐食,这也促使餐饮行业不断开发新的方便食品。新型的加工方式——真空低温烹调已经在餐饮和饭店得到广泛应用,国外已有真空低温即食加热产品,但在国内对此关注得极少。本文介绍了真空低温烹调技术、开发真空低温方便食品的意义和国外真空低温方便食品的研究现状,以期为中国传统美食标准化加工及食品工业发展提供新的技术思路。     

现代化厨房设备的市场开发思路

家用电器进入厨房是居住条件达到小康水平的重要标志如果说家用电器进入寻常百姓家庭成为80年代人民生活水平大幅度提高的象征,那么完全可以说厨房中引入成套系列的家用电器将会成为90年代我国人民居住条件达到小康水平的一个重要标志。家用电器进入厨房使食品从冷藏、解冻、备餐到烹饪的许多过程实现自动化成为可能,可采用多种能源的灶具、炊具允许用户可选择多种加热手段烹调食品,大大减化了人们繁琐的家务劳动。     

食品领域的化学性危害及防治

食品安全是关乎到人们健康和安全的重要问题,保障食品制作与食用安全是我国食品管理工作的关键任务。食品的生产过程包括加工、储藏及烹调等环节,均存在被有害物质污染的可能。基于此,主要从食品的化学性污染及危害出发,着重探讨食品领域中化学性危害的防治。旨在通过该理论研究实现对食品领域化学危害的有效防治,提高食品安全性。     

食品安全人们何时不揪心

“民以食为天”,食品是人类赖以生存的能源,随着社会不断进步和发展,人们对食品的要求不仅仅是温饱的需要,而且要求除提供各类合理、足量的营养素外,对食品的安全、卫生要求越来越高。食品的卫生状况直接关系到人的生命健康,如果食品不卫生,包括病原生物在内的各种有害因素就会     

探究食品检测实验室的质量监督

质量监督是食品检测中的重点内容环节之一,通过严格控制食品检测质量,可以确保检测结果的准确及客观。在食品检测质量监测过程中,如果质量监督的标准不同,也会导致监督活动效果受到影响。本文结合食品检测质量监督中的实际问题,进行以下内容探讨。     

SOME NUTRITIONAL EFFECTS OF COOKING

Food is cooked to make it more appetizing and/or make it safe to eat. When food is heated there will be a reduction in heat labile nutrients and if liquid is used soluble nutrients may be lost. Thus cooking is a compromise aiming to make the food safe and at the same time optimize nutrient content and sensory appeal. Examples of the effect of cooking on the retention and availability of some nutrients have been discussed.     

论大米的营养强化类型

大米作为人类的主食,拥有丰富的营养物质,对于人类的生活至关重要。但是,大米在加工、储存及烹调过程中,会使很多营养物质遭到破坏和流失,大大降低其营养价值。而营养强化大米就能很好地解决这一问题,其相比于普通大米而言,具有更高的营养价值。     

论炒菜的不良习惯

在日常生活中,如果炒菜不注重正确的操作,形成炒菜的不良习惯,不仅会影响食物的口感,还会对人体造成一定的伤害。所以,无论是炒菜前,还是炒菜中,都应该尽量避免不良习惯,这才是炒菜的健康之道。所以,在炒菜的时候,应该避免不良习惯对炒菜的影响。本文通过营养、炒菜过程以及健康3个方面对炒菜的不良习惯进行阐述,希望能够对今后的炒菜意识提升有一定的帮助作用。     

What are student preschool teachers learning about diet in their education in Norway?

This article is based on a qualitative study on diet education among student preschool teachers. The problem under discussion is: What does a student preschool teacher learn in his education about food, meals, and nutrition? The material used in the article comprises interviews with student preschool teachers at one university and one college in Norway. Preschool teacher education is a three years university college study with bachelor degree. The survey results show that student preschool teachers do not receive even the most element training, when it comes to food and meals, including nutrients, vitamins, and minerals, although education must prepare them for a job outside the kindergarten. Practical cooking was almost completely absent in their education, including hygiene. Most student preschool teachers did not know what fat they were to use in cooking. Food and senses, allergies, and food and culture were not discussed in their education. There was little correlation between the formal curricula in connection with food and meals and the training the preschool teacher students received in their education.     

河豚鱼菜肴的最佳烹调方案

高品质生活是广大人民的普遍追求,随着人们生活水平的提高,人们的饮食结构也得到显著改善。河豚作为一种特殊的鱼类,具有很高的食用价值,是人们十分喜爱的美味佳肴。但由于河豚自身含有剧毒,不能简单烹调食用,因此,在具体烹调时需对其进行正确处理,在各烹调材料搭配上要合理有度,并在选材上也要以人工养殖河豚为主。本文对河豚鱼菜肴的最佳烹调方法进行研究。     

How does a local initiative contribute to social inclusion and promote sustainable food practices? Focus on the example of social cooking workshops

Initiatives from food system players closer to citizens are currently valorized to promote sustainability. Based on TCR and on the practice theories, this research aims at studying the impacts of a local initiative on two aspects: social inclusion and sustainable food practices. To do so, we chose the example of cooking classes for people in social instability. Cooking classes may contribute to fight against social exclusion through two factors: first the group dynamic and then the value‐creation for participants. Besides, cooking classes may drive towards sustainable food practices on the basis of advice about new skills. Cooking classes in three different social service structures were observed: a Social Centre; a social service structure hosting young people suffering from homophobia; and, a hosting centre for people with disabilities. To complete these observations, semi‐directive one‐hour interviews were conducted with three participants from the different groups. This information was analyzed with thematic analysis and practice theories tools. Results show that the main factor of social inclusion is the value‐creation, with two factors contributing to people's self‐esteem: (re)teach them how to cook; and offer them the opportunity to cook and eat good food. The cooking classes are efficient to promote sustainable food practices, promoting at the same time the interest in shared‐eating, shared‐cooking, and new skills. Nevertheless, it is not enough for the people to adopt new practices because of material and logistical barriers. As such, our findings are important for policy makers tasked with promoting sustainable consumption and social insertion within vulnerable population.

Cooking,recipe use and food habits of college students and nutrition educators

The purpose of this study was to revisit Lewin's gatekeeper theory to observe current food role patterns (cooking experience, recipe sources, and both daily food consumption choices and eating out) with contemporary groups of college students (n = 292) and of nutrition educators (n = 26). Male college students equalled female students in cooking ability, use of family as a prime recipe source, and frequency of eating out, while exhibiting different food consumption excesses and deficiencies. Package labels and the Internet were most frequently identified as recipe sources by college students. Nutritionists surpassed both male and female college students in most attributes.
