五食用昆虫你真的应该尝试

五食用昆虫你真的应该尝试Tostadas chapulines CON huitlacoche。 狂欢节国王08

食用昆虫是肉食传统能源替代大,因为他们是蛋白质和脂肪便宜,丰富和优秀的来源,以及维生素和矿物质。

在许多国家,吃虫不引人侧目。 他们怎么可口出现一个人在很大程度上是由文化决定的。

昆虫的分析还显示,营养价值和构成巨大差异 - 种,发展阶段,甚至由于昆虫的饮食之间。

周围 2000食用昆虫种类 在世界范围内,那些下面是一些更好的选择吃。

草蜢

蛋白质是昆虫的重要组成部分,蚱蜢,蝗虫和蟋蟀(直)脱颖而出。 顶级供应商的蛋白质被称为墨西哥有高达77.13%的蛋白质含量chapulines蝗虫。 而且其蛋白质值很多倍,比上chapulines包括玉米,大豆和苜蓿饲料常用的植物高。

从农田蝗虫这些在赞成使用农药不仅会控制这些害虫,减少土壤和水的污染,而且还提供额外的食物和收入的集合。

Chapulines通常与鳄梨酱和玉米饼吃。

棕榈蛴螬

棕榈象鼻虫(甲虫)的这些软体幼虫被广泛食用美洲(Rhynchophorus palmarum), south-east Asia (Rhynchophorus ferrugineus) and tropical Africa (Rhynchophorus phoenicis).

Larvae of the African palm weevil contain up to 69.78% fat. Because they are fried in their own fat, they don’t need any extra oil. But they’re also eaten raw.

Cultivation Of Grubs In Indonesia

脂肪是昆虫的第二个重要组成部分,构成食物中的能源最密集的营养素。

在巴拉圭东部的阿切人吃了动物性食品,这些蛴螬是最好的能源供应商 - 比蜜还要好 - 所以手掌蛴螬犹如自然能量棒。

不饱和脂肪酸(好的教师)是那些一般也占优势的食用昆虫,它们还含有较多的不饱和脂肪酸(真正好的)比家禽和鱼。 Rhynchophorus phoenicis 富含这些多不饱和脂肪酸,还含有亚油酸和α亚麻酸酸 - 两个必需脂肪酸对儿童和婴儿的健康发展尤为重要。

Some indigenous peoples in south-east Asia already semi-cultivate palm grubs - like the sago grub (Rhynchophorus ferrugineus), which feeds on the sago palm. They fell palm trees deliberately for the palm weevil larvae to grow, and between one to three months later up to 100 grubs can be found in a single trunk. Easier indoor cultivation has been developed in Thailand.

Descriptions of texture and taste of the sago grub include creamy when raw and when fried.

Mopane Worms (or Caterpillars Actually)

Most edible insects have equal or higher iron contents than beef, which has an iron content of 6mg per 100g of dry weight, while the iron content of the mopane capterpillar (Imbrasia belina), for example, is 31–77mg per 100g.

The mopane caterpillar is one of the most consumed and economically valuable edible insects in southern Africa and could go some way to improving iron deficiency in the diet.

Iron deficiency is the world’s most common and widespread nutritional disorder according to the World Health Organisation. In developing countries, around a half of all pregnant women and about 40% of pre-school children are believed to be anaemic (anaemia can be caused by iron deficiency).

Attempts to semi-cultivate and domesticate the mopane caterpillar for food has had positive results but many issues remain before they can be more widely used, for example their susceptibility to viral and bacterial diseases.

Mealworms

Mealworms are particularly interesting for western diets and mass-production. Their overall nutritional value is comparable to beef, they are endemic in temperate climates such as in Europe, and mass-rearing is already in place in the pet industry and for feeding birds.

Several companies that produce mealworms in the Netherlands are now using their knowledge and facilities to mass-rear mealworms for human food.

Importantly, the ecological footprint of mealworm production is much lower than that of beef, but also milk, chicken, and pork production. Although the production of mealworms requires similar amounts of energy, it has lower emissions of greenhouse gasses (for example less methane that you’d get in rearing cows) and requires much less land. Water use is also much lower.

Mealworms can easily be processed in foods. Preliminary results of experiments conducted at Wageningen University indicate that the texture and taste of processed foods that contain mealworms are very well accepted by western consumers.

Black Soldier Flies Maggots

These flies are excellent both as human food and as animal feed.

Dried black soldier fly prepupae (maggots) contain 42% protein and 35% fat. Live prepupae consist of 44% dry matter and can easily be stored for long periods.

As a component of a complete diet, they have been found to support good growth in chicks, pigs, rainbow trout, channel catfish, and blue tilapia

When used as animal feed, the black soldier fly can also be reared on manure of poultry, pigs, and cattle which reduces manure mass, moisture content, offensive odours, and the pollution potential of manure by 50–60% (for example, chromium, copper, iron, lead, zinc), and can also reduce harmful bacteria such as E-coli and Salmonella.

Growing them is easy; either 在后院 and as one recent invention shows, also in the home.

关于作者谈话

Joost van Itterbeeck, PhD student, Wageningen University. His current research concerns the resilience of a colony of Asian weaver ants (Oecophylla smaragdina) to harvesting its larvae and pupae for human food in the Lao PDR. The focus is on biological aspects.
