Silkworm pupae are insects that are beneficial to human health, not only for their high nutritional value but, more importantly, for the variety of pharmacological functions they can perform when consumed.蚕蛹对人类健康的意义是有益的,营养价值高,更重要的是食用后可发挥多种药理作用。
1. Introduction一、简介
The silkworm is a lepidopteran insect. The life of a silkworm usually goes through five stages, lasting a total of about seven weeks. When the silkworm eggs hatch, they turn into newly hatched black and brown silkworms. After feeding and growing and shedding its shell five times, the silkworm becomes a mature silkworm, stops feeding, and starts to spit out a lot of silk in preparation for cocooning. This process takes 蚕是一种翅目昆虫周。蚕的一生经历了七轮左右,每天一次约当蚕卵出现时,它们会新出现的黑色和蚕丝。经过五次喂食、喂食和喂食壳后,蚕变成了成熟的蚕丝,停止喂食,吐出的丝,准备结茧。这个过程需要24
–28 days. After 4 days of cocooning, the matured silkworm turns into a silkworm pupa. After about 2 weeks, the silkworm pupae turns into silkworm moths. The silkworm moths finish laying eggs within 3–5 days and die soon afterwards. Silkworm pupae are considered to be the harvest period for silkworm consumption as they are consumed as food in many regions due to their high nutritional value and various biomedical functions.-28天。经过4天的结茧,成熟的蚕变成了天蚕丝。大约2周蚕蛹在3-5岁时,多次产后并死。 。 Figure 图1 depicts画了蚕的生命周期[图1 the, life2 cycle of the silkworm [1][2].]。

Silkworm蚕蛹是丝特别工业的主要一种,在东南亚主要制造动物产品和饲料和肥料,例如日本、韩国和印度它们 pupae[ are3 one of the main by-products of the silk industry and are mostly used as animal feed and fertiliser in South East Asia,
for4 example in Japan,
Korea,5 and India [3][4][5]. Silkworm pupae are also used as food insects, especially in China, where they have been eaten for over ]。食用2000
多年[ years6 [6]. There are many species of silkworm pupae; at present, the main commercial silkworm pupae used for research are]。蚕蛹的种类很多;目前,用于研究的主要蚕丝蚕有 Bombyx mori,家蚕、 Antheraea pernyi,蚕柞蚕、山麦柞蚕、 Antheraea yamamai,柞柞柞蚕、山麦柞蚕、柞柞柞蚕、桃花柞蚕、黄花柞花 Samia ricini, Antheraea mylitta, Antheraea roylei,等[ and4 other species [4][7][8]. Additionally,
the7 material composition and functional roles of these species are different. The biggest difference between the different species of silkworm pupae is the source of the silkworm’s diet and the degree of domestication. For example,

Rich in proteins, oils, chitosan, vitamins, polyphenols, and other nutrients, silkworm pupae have long been used as an important source of high-quality proteins and lipids [9].

Some researchers have used silkworm pupa powder as a protein enhancer in functional foods, and the addition of silkworm pupa powder enhances the flavour and taste of functional foods [13][14][15]. Examples are bread, yogurt, and food additives [7][13][16]. In addition, silkworm pupae can also be used in industry [17]. However, silkworm pupae are still not accepted by everyone because of the presence of allergens and unfriendly odours. We need to consider the safety and acceptability of silkworm pupae more thoroughly when using them [18]. In recent years, numerous studies have found that the active ingredients in silkworm pupae have various pharmacological functions, such as: anticancer, antioxidant, hepatoprotective, antibacterial, antiapoptotic, and immunomodulatory functions. This provides a broader prospect for the application of silkworm pupae. In the future, silkworm pupae will rapidly be developed for the health food and biomedical industries to meet the human demand for nutritious food and safe medicine [19][20].20 ]。
2. Components of Silkworm Pupae蚕蛹的成分
Silkworm蛋白质、脂肪和是最丰富的物质,还有糖成分、维生素、多酚和许多其他营养物质[ pupae21、22 are rich in many nutrients. Protein, fat, and sugar are the most abundant substances, as well as minerals, vitamins, polyphenolic compounds, and many other nutrients [21][22].]。
2.1. Silkworm Pupae Protein。蚕蛹
Bombyx mori has的蛋白质含量高达 a high protein content of 55.6%5.6%,是蚕蛹中最丰富的干肽[ 9 dry] weight。八种蜂蜜可以产生各种活性剂,由各种不同的蚕蛹的多肽成分组成。多种蛋白质的成分在各种蚕丝中基本相同, and is the most abundant dry matter in silkworm pupae [9].Biologically active peptides are peptides containing from several to several dozen amino acids, which have a variety of physiological functions [23]. These pupae proteins can be hydrolysed to produce a variety of biologically active peptides, which in turn can perform the pharmacological functions of silkworm pupae. The amino acid composition of the proteins is essentially the same in the different species of silkworm pupae, all consisting of 18 amino acids (except for其中 Eri silkworm pupae). Of these, eight essential amino acids meet the requirements of the WHO,每种蚕丝可以产生多种活性成分。符合粮农组织/
FAO/UNU recommendations. In addition, there are 联合国大学提出的要求。除此之外,还有10
non-essential amino acids that meet human requirements. Compared to hen eggs, pupae are higher in Phe and Pro种满足世界卫生组织/世界卫生组织的要求。与认为,Phe和Pro的含量增加了[ [24].24 Therefore,]。因此,蚕是优质的的蛋白质来源和蚕蛹的重要营养成分[ silkworm25 pupae are] considered to be a high-quality source of protein and an important nutrient in silkworm pupae [25]. Table 1 summarises the amino acid composition of the different varieties of silkworm pupae proteins.总结了不同的蚕蛹蛋白质的组成。

2.2. Silkworm Pupae Oil蚕蛹油
In silkworm pupae, the oil content is second only to protein. Of the four different species of silkworm pupae,在蚕丝中,油脂接触蛋白。在四种不同的食用量中, Eri埃里 silkworm pupae has the highest oil content, at 蚕丝的含含量最高,为26.2%
[ [22].22 The fatty acid composition of the different varieties of silkworm pupae oil is summarised in Table ]。表了我们从不同的蚕油 中蚕丝组合见表2. As can be seen from the table, all the different silkworm pupae oils contain high levels of unsaturated fatty acids, with 。中可以不同,所有不同的蚕豆油都含有高高的内里的,柞7

In%。除了表中和外用的两种,蚕丝还含有二十五分之二它们是一种物质,是蚕丝的重要的油脂,含有丰富的油脂,而且特别是不营养,尤其是多种来源的商品,作为食用油的来源具有重要的营养价值[ addition12 to the fatty acids listed in the table, silkworm pupae also contain eicosapentaenoic acid and docosahexaenoic acid, which are Omega-3 fatty acids and have an important role in promoting human health [26]. Oil is an important nutrient, and silkworm pupae are not only rich in oils but also contain high levels of unsaturated fatty acids, especially polyunsaturated fatty acids, which have significant nutritional value as a source of edible oil [12].]。

. Non-communicable diseases include stroke, hypertension, cardiovascular disease, etc. [31][32]. Some pupae are also rich in selenium, which can be enriched in the pupae protein. Selenium-rich pupae play an important role in cancer prevention and defence against oxidative stress [33][34].31、32 ]。作用,重要作用在预防和预防冠状病毒343333中发挥作用。

2.3. Minerals反而
Minerals25种重要的生物体中表现出不同的生理功能。 have an important role in living organisms. They are present in many forms in silkworm pupae. There are up to 25 different types of minerals in silkworm pupae, and these minerals may perform certain physiological functions in the organism [7][12].3个 Table 3表 lists中共有8种品种的含量、种类、种类、钙质,含有中等长度的钙长品种。 the[ content24种不同的蚕丝中] of[ eight29,30 minerals] in。。。发生率疾病传染性疾病中风,高血压血压,心血管心血管疾病[ the three types of pupae, from which it can be seen that phosphorus, calcium, and magnesium are higher in the pupae. The type and content of minerals in pupae can vary depending on the type of pupa and the environment in which they have grown [24]. It is worth noting that the sodium-to-potassium (Na: K) ratio in silkworm pupae is very low, except for the minerals listed in the table. Na:K predicts the occurrence of non-communicable diseases, suggesting that consumption of silkworm pupae may reduce the likelihood of non-communicable diseases [29][30]
2.4. Other Ingredients in Silkworm Pupae蚕蛹的其他成分
In addition to the above ingredients, silkworm pupae contain many vitamins and are rich in them. For example, 蚕蛹以上成分外,还含有多种维生素,含量丰富。例如,VA
can reach 可以达到5 mg/g
. The main vitamins in silkworm pupae include VA, VB1, VB2, VB3, VB5, VB7, VB9, VB12, VC, and 。蚕中除VB1的主要维生素有VA、VB2、VB2、VB5、VB7、VB9、VB12、VC、VE

The five tocopherols are α-Tocopherol, β-tocopherol, γ-tocopherol, γ-tocotrienol, and σ-tocopherol [28]. Rare dimethyladenosine derivatives are also found in silkworm pupae [37]. Additionally, silkworm pupae contain polyphenols and flavonoids. Polyphenols and flavonoids were found in the pupae of the silkworm和 7 种酚类也发现多种黄酮 Antheraea assamensis at类。 concentrations of 10 mg/g

The sugars in silkworm pupae can be divided into two main groups, chitosan and chitin, as well as isolated and purified polysaccharides, all of which are biologically active [ 39 ] [ 40] [ 41 ]. Chitosan and chitin from silkworm pupae are not cytotoxic, but have strong physiological activity, especially carboxymethyl chitosan [ 42 ] [ 43 ]. All these substances had certain biofunctional activities, which contribute to the basis of the pharmacological functions of silkworm pupae. [ 44 ] [ 45 ]
