How to make the orange fleshed sweetpotato crisps taste good and be more nutritious



Today I read an article about how to make orange fleshed sweetpotato crisps at good nutrition.I think it is useful for foodies,share with you:

The study was carried out to determine the effect of salt on the sensory, nutritive and keeping quality of OFSP crisps. Crisps were made by deep frying slices of approximately 3.5 mm thickness treated with, 2% and 4% table salt. A control with no salt treatment was prepared alongside the treated ones. Two varieties of OFSP; Ejumula and Kakamega were used in the study. After deep frying, the crisps were cooled to room temperature, packed in paper-lined high density polythene pouches and stored in a dark cupboard at room temperature for three months. During the storage period, the crisps were analyzed for proteins, fat and carotenoid content. Changes in sensory attributes were analyzed using a semi-trained panel. Results indicated that freshly prepared crisps treated with 2% salt had the highest acceptability mean scores for all attributes while there was no significant difference (p > 0.05) between crisps made from either Ejumula or Kakamega variety. Carotenoid content decreased with increase in salt concentration in both OFSP varieties. Shelf-life studies showed that the decline in sensory attributes started after 2 months of storage. The study shows that OFSP crisps treated with 2% salt are more acceptable and reasonably stable during storage.

The above is the brief,and you can read the full article for more details.

Children likes tease mother more than father , this is a phenomenon over the world




Do you often tease mother or father when you are a child?I think most people may tell me :It is mother. It is very common in our life.
A research made by Nerea Portu-Zapirain  explores representational models in a sample of 111 children aged between 3 and 6.Finally confirm that security in the representation of attachment is higher with mothers worldwide.
Why?I think it is may be when we are a child,mother takes care of us more.There has been a research indicated that the baby's conscious and memory starting around 5 months after birth.So at the age of 6 month’s old,the baby may have a certain sense.
Besides, “The older the child, the greater the security manifested in their relations, and the younger the child, the greater the insecurity. ” Nerea Portu-Zapirain wrote in his paper.

How to deal with problem child?A case that Obama warns daughters on “family tattoo”




In order to discourage teen rebellionBarack Obama has warned his daughters that if they get tattoos, he and his wife will get matching ones on the same place on their bodies.As US PresidentObama also have to consider education of children.

Indeed,children's education is of great importance for parents, especially the problem children.When we found our children deviating from the right orbit,we are anxious.For some parents,they are helplessness. Not everyone is Obama.Some parents don’t know how to effectively prevent children do the wrong thing,and how to deal with their “problem child”.

There is an article introduces a method or makes a research on this common phenomenon.I hope it can be helpful for parents and the researchers in this field.More and more better researches are excepted .

Studying gaze abnormalities in autism: Which type of stimulus to use?



Background: Eye-tracking has been used to investigate social perception in autism spectrum disorder (ASD) with variable results. This heterogeneity may be due to the types of stimuli used. In this study, we investigated whether the use of moving vs static stimuli or human actors vs cartoons characters would be more sensitive in detecting gaze abnormalities and discriminating children with ASD from typically developing children.
Methods: We studied 18 children with ASD (mean age = 12.9 ± 2.9) and 21 typically developing controls (mean age = 11.3 ± 2.5). Gazes were tracked using Tobii-T120 eye-tracker. Four different types of stimuli were presented: movie with human actors, cartoon movie, picture with human actors and cartoon picture. To identify the type of stimuli that best discriminate the ASD group from the control group, a two-way ANOVA was performed using ecological dimension [human-actors/cartoon] and presentation form [movie/picture] as factors.
Results: Children with ASD presented significantly less fixations to eyes and faces in the movie with human actors and in the picture with human actors. Children with ASD also presented significantly more fixations to non-social backgrounds in the movie with human actors and in the cartoon movie. A significant ecological effect was observed for the reduction in fixations to the eyes [human-actors > cartoon]. A significant presentation form effect was observed for the increased fixations to the non-social background [movie > picture].
Conclusions: The direct comparison of gaze behavior across four different types of stimuli demonstrates that gaze abnormalities in ASD depend on the type of stimuli that is used. Our results suggest that general gaze abnormalities in children with ASD are better detected when using dynamic stimuli, and finer details of these abnormalities, especially looking less to the eyes, are better detected in a more ecologically relevant situation presenting human characters.

Protein Quality Evaluation of Animal Food Proteins by In-Vitro Methodologies




Meat is a valuable food for human.It provides us complete protein, vitamin and all kinds of other nutrition.It also provides us some nutrition which is rare in vegetarian diet,such as zinc, vitamin B12, Calcium, iron.Besides,the meat quality is important.There is a research evaluat the protein quality of some animal food sources:
In this study, the protein quality evaluation of these animal food sources, highly produced and consumed in Sonora, is proposed, using in-vitro methodologies. Four different species, from each aquatic and terrestrial origin, were selected. Samples of lean muscle were used in all cases. Various in-vitro methodologies for protein quality evaluation were selected, alternatives to the animal bioassays: % digestibility, Total amino acid analyses (HPLC), PDCAAS, computerized PER calculations (C-PER and DC-PER) and total collagen contents. % in-vitro digestibility presented significant differences among samples from terrestrial species, but muscle from aquatic species did not showed significant differences. All sources of proteins, both aquatic and terrestrial proved to be rich sources of essential amino acids. PDCAAS was unable to establish significant differences in protein quality among sources of protein from different origin. Both methods C-PER and DC-PER were more exact in their results and were able to detect significant differences among samples of different origin. An important finding was the great difference in the total collagen content between aquatic and terrestrial sources of proteins, where terrestrial muscle proteins had almost 10-time more collagen than aquatic protein sources. However, these collagen contents did not seem to have a significant influence in the protein quality of these animal proteins. These muscle proteins, from both aquatic and terrestrial species, confirmed to have a high protein quality and some of the in-vitro methodologies used in this study represent a valuable alternative to the animal bioassays.

Will human continue to live longer in future?



Recent discoveries show steady improvements in life expectancy during modern decades.Yes,better food supply and nutrition, better hygiene,the popularization of health knowledge does make me enjoy a longer life.According to Wikipedia,a French has ever lived for 122 years,a Japanese is 116 years old so far still alive.Will human continue to live longer in future?A research named < Predicting human lifespan limits>published in Nature Science takes industrialized countries as an example,and analyses the limits that will affect our “longevity”.You can read this research for more detail.

Which city planning makes for reducing bicycle crash



Compared with cars,bike seems to have some advantages that cars can’t instead.Such as: environmental protection, save money , no traffic jams and good for health.Thus,some people prefers bikes.But there lies a big problem for riders: safety.A research from Scientific Research Publishing analyses 5 years of bicycle crash data from the city of San Francisco and make recommendations on how planners and design professionals can keep bicyclist safety considerations in mind.You can learn more by reading the full article.
